2 Introduction

The Audio Visual Guidelines and Standards have been developed to ensure the AV (Audio Visual) facilities across Flinders University are designed and constructed to the same standard and to a consistent platform.

The guidelines provide Architects, Engineers, Consultants and Contractors with requirements to design and implement a successful AV installation. Additionally, the guidelines provide Flinders University faculties, departments, project managers and individuals with an understanding of best practices and the minimum requirements for the different types of teaching and learning spaces. Where these standards cannot be adhered to, consultation must be sort during the design stage and prior to the commencement of works with Flinders University ITS AV staff.

The Audio Visual Guidelines and Standards does not define architectural, electrical, network and cabling standards (please refer to the Flinders University Campus Cabling Standards) and acoustic standards or national standards and building codes.

Flinders University ITS AV notionally endorses the AETM AV guidelines as a companion document subject to the specifics of the Flinders University audio visual specifications.

3 Process

The design of modern learning spaces with integrated educational technology requires a coordinated project team and collaborative process from the earliest stages of project definition and concept design. The project team should consist of project managers, key stakeholders, ITS network, AV staff and finally the users of the teaching space. The solutions needed to meet the requirements of modern teaching and learning often includes distributed AV solutions with sophisticated media and communications technology.

The technology solution chosen for each venue can substantially change the special requirements and budget for learning spaces. Therefore, it is critical to consider AV solutions at early stages of the project. To formulate a project preliminary budget or architectural concept without the early input of AV expertise will put the project at risk unnecessarily. The most cost effective time to make changes is early in the project lifecycle.

AV expertise is required at the earliest feasibility stages to: • document the technology functionality requirements of those who will use the spaces • discuss technology options with clients and stakeholders including the institution’s AV staff • develop a technology concept that can then be incorporated into the project feasibility

assessment, preliminary budget estimate and the design brief that goes to market

Any successful project which includes a professional audio visual installation must provide for clear definition and management of goals, processes, resources, and responsibilities between the design and installation project teams and the client.

Flinders University Information Technology Services requires all audio visual integrators and consultants to provide schematics and equipment lists to allow a thorough review of the proposal before we consider the tender or quote as conforming.

At the point of handover of a new audio visual installation, Flinders University ITS AV will inspect the installation and confirm it complies with the tender specification. The audio visual integrator is to supply Flinders University Information Technology Services with a fully functional AV System with the inclusion of:

• As Built Schematics in an electronic format in CAD, DWG, Visio and an additional PDF version must be created:

o Equipment – Make and Model o Connection type – RS232, LAN, HDMI, DVI, Balanced Audio, etc. o Cabling – Make and model o Labelling of cables – as per the actual installed cabling

• A single A4 custom Room User Guide per space in both word document and PDF format • Manufacturers operation manuals and warranty details in an electronic format • Floor plan highlighting equipment and cabling location in PDF format. • Accurate table of all IP Devices which includes Make, Model, Description, MAC address serial

number and IP address in an .xls format • Electronic copy of any source codes and data base file for devices such as the Crestron

control system, Crestron Touch Screens, Digital Audio Processor, Lighting Controllers • A response to the defect, issues and improvements check list created by the University at

the time of commissioning within 5 days of issue from the University in an .xls format.


4 Lighting Design

4.1 Introduction

The presentation of PowerPoint slides, websites and other visual material is an essential part of modern teaching and learning and the clarity of these images is critical to the successful use of the venue. Poor lighting design can ruin the effectiveness of projected presentations making them “washed out” and hard to read. Consequently, the importance of lighting design in all presentation and teaching spaces cannot be over-emphasized.

Design Goals

In the majority of teaching spaces, the lighting design must have the following objectives: • Control all ambient light to allow the required contrast in projected images • Provide note taking light and if required task lighting for students • Properly illuminate the presenter wherever they are in the presentation area • Properly illuminate any demonstration and presenter work spaces • When user interaction is required, the layout and design of the interface is simple.

Selection of Light Fittings

The legibility of projected images is totally dependent on the careful selection, arrangement and control of light fittings. It is essential to select fittings which provide a high degree of directional control. Lighting divided into zones; dimming (or at least selective switching); directional ambient and task lighting; spot lights; and easy to use control systems are the tools required to achieve effective lighting in presentation and teaching spaces.

During a presentation different lighting settings may be required in rapid succession. It is essential that the lights used be capable of being switched on and off (or dimmed) quickly. Lighting which requires long delays between extinguishment and re-strike, or fittings which take more than 10 seconds to achieve maximum brightness are not suitable for general purpose teaching spaces.

Control

Presenters need access to flexible but easy-to-use lighting controls located at the presentation position. Best practice involves the integration of lighting control with the AV control system. In larger spaces this is an essential requirement.

4.2 Lighting Zones and Circuits

4.2.1 Small to mid-sized teaching and presentation spaces with projection

For small to mid-sized teaching and presentation spaces with projection three lighting circuits* are the minimum that shall be provided to allow sufficient zone control of lighting. Each of the circuits should preferably be controlled by a separate dimmer or by a relay controlled contactor if this is not possible.

Provide separate light fittings and switching circuits for: • Front lights that spill directly on the screen (including board lights) • Directional task/spot lighting to illuminate the presenter at the lectern or presentation

position without spill on the screen • Audience area room lights.

*Other zones/circuits may be used if required, and these should be switched or dimmed separately.


Directional lighting of the presentation area is a strongly recommended feature for even small venues. Without it, the presenter will either be in the dark while presenting or will they will turn on the board lights thereby "washing out" the projected presentation.

Figure 1 below illustrates a typical three circuit layout consisting of separate lighting instruments and control circuits for Board lights, Presenter illumination and audience (note taking) lights. Note that in small rooms, even if specific board lights are not used, it may be necessary to isolate the lighting nearest the screen surface so that it may be switched off during projection without affecting the note taking lights over the general audience area. Presenter lighting should be angled horizontally and or vertically by between 45 and 60 degrees to avoid dazzling the presenter and to enable them to maintain eye contact with the audience.

Figure 1: Typical Three Circuit Lighting Scheme

4.2.2 Lecture theatres and larger presentation spaces with projection

For lecture theatres and larger presentation spaces multiple lighting circuits shall be provided to allow sufficient zone control of lighting. In addition to the three zone scheme used in smaller teaching spaces it is usual to provide more sophisticated control over the audience area and the presentation area. All zones must be under the control of the presenter via dimmers with the exception of Exit, stair tread and safety lights (which may be required to be always on).


Provide separate light fittings and switching circuits for: • Board lights (as required) • Directional front stage area lighting, either spot lighting with cutters/barn doors or other

forms of directional lighting that do not spill on to the screen(s). The stage lighting shall be broken into multiple zones for large venues (e.g. Stage Left, Centre and Right)

• Lectern/presentation point focused spot lights with cutters/barn doors to ensure no spill on to the screen(s)

• A minimum of 3 audience lighting zones (e.g. front, middle, back) • Aisle lights • Safety lights • Other zones/circuits as required (e.g. for demonstration or performance spaces) • Overall lighting zones or scenes (on, off, presentation).

4.3 Ratio of Projected Versus Ambient or 5.4 “Spilled’ Light

As discussed already, the clarity of projected images relies on a sufficient contrast ratio between the light from the projector and the ambient or spilled light falling on the projection screen. AETM endorses the ANSI/ICIA published specification regarding contrast ratios in projected images (ANSI/INFOCOMM 3M-2011: Projected Image System Contrast Ratio). As these standards apply to the tertiary environment, we can identify three situations:

• Projection of Text and Graphics (e.g. PowerPoint Slides or Visualiser) where it is expected that reasonable ambient light levels are provided for note taking

• Projection of detailed photographic images (including medical images and x-rays) where notetaking is secondary to a full contrast ratio projected image which allows for the reproduction of detail in the darkest areas of the picture

• Projection of moving images (Film and Video) where note taking is secondary to a full contrast ratio projected image which allows for the appreciation of detail in both the brightest and darkest scenes in the presentation.

It is the responsibility of the lighting designer, working with the audio visual design consultant, to ensure that ambient light from all sources is sufficiently controlled so that the minimum recommendations regarding contrast ratio are achievable at the any point on the image area. If this is not achieved the imaged will be “washed out” and be hard to read.

Control of ambient and spilled light falling on the projection screen is essential in all spaces with projection, but it is absolutely critical in larger venues. Large venues require large screens which in turn require powerful projectors. For example, using the inverse square law we know that a screen twice the width requires a projector 4 times as powerful to achieve the same brightness on the screen. In general, the audio visual designer will declare the target illumination the projector is able to achieve given the screen size.

Compared with classroom situations described above, the projected light reflected off the screen will often be substantially reduced in these larger venues. Therefore, to retain a sufficient contrast ratio between projected and ambient light the ambient light falling on the screen the lighting designer must take particular care with the directional control of light fittings and the control of external ambient light sources such as daylight.

Light coloured floor coverings and furniture near the projection screens should be avoided as much as possible since they will reflect significant amounts of light from the spot and stage lights onto the screens.


4.4 Target Light Levels

Actual lighting levels in practice will be set by reference to: first Australian Standards (where appropriate) and secondly to the requirements and standards set by the individual institution concerned. Where no institutional standards exist, this section will provide guidance as to typical situations found in undertaking the lighting design for a larger multi-purpose lecture theatre.

For a typical lecture theatre, three lighting examples are defined: • ON (also used as Entry/Exit lighting without board lights). This is often defined as full

lighting. • PRESENTATION. This is the most commonly used state and is used when the projected image

or like whiteboards are in use. • OFF. All lighting, excluding OHS related, is dimmed to zero percent. Commonly used for

movie or like presentations.

In addition, the following measurement points are defined: • At the surface of each student writing surface (horizontal plane) • In the presentation area (horizontal and vertical planes) • On the whiteboard writing surface where fitted (vertical plane) • Spill and ambient light on the projection surface (vertical plane) • Stair treads and safety lighting

4.4.1 Design Lighting Levels

• Spill light from all sources to be limited so that a contrast ratio of 50:1 is achieved between the level of white illumination produced by the projector across the entire screen surface and the level of ambient light incident on the screen

• The specific expected white level from the projector should be confirmed prior to lighting design. However, as an example, where 500 lux is achieved as projected peak white, spill light from all sources must be <10 lux at any point within the image area of the screen

• Where practical, note taking light in student seating area shall be capable of producing up to 50 lux measured on the horizontal surface of each student writing bench and shall have dimming control allowing adjustment down to 0% of full brightness with no noticeable flicker. Where note taking light cannot be achieved without compromise to the amount of spill light on the screen, then note taking light is to be reduced or eliminated

• Presenter illumination is not required in this mode • Whiteboard surface illumination is not required in this mode • Stair treads: refer to applicable Australian standard or local specification.

4.4.2 Light Fitting Selection Light fittings with good directional control are required to eliminate glare and unwanted lighting spill on projections screens. The closer the lights are to the projection screens the more important this requirement becomes.

Light fittings without horizontal shielding and louvers, or light fittings that bounce light off ceilings or other surfaces do not provide sufficient directional control and are not suitable for spaces with projection. Low brightness non-reflective louvers are preferred.

During a presentation different lighting settings may be required in rapid succession. It is essential that the lights used be capable of being switched on and off (or dimmed) quickly. Lighting which requires long delays between extinguishment and re-strike, or fittings which take more than 10 seconds to achieve maximum brightness are not suitable for general purpose teaching spaces


General Light Fittings Compatible with Projection

To achieve low levels of ambient light spill onto projection surfaces, light fittings must of a glare free design with direct light distribution only (i.e. no upward incident light) and have reflectors with cut off or shielding angles of 50 degrees or less in the direction of the screen(s). Recessed lights with non-reflective louvers or suspended lights with sufficient side shielding reflectors and non-reflective louvers are usually suitable.

Examples of light fittings with sufficient light cut off or shielding:

Figure 2: Shown above is a louvered fluorescent fitting suitable for use in rooms with projection along with a

In addition to the requirements for general room lighting, fluorescent light fittings that are not turned off during projection must be equipped with low spill reflectors/louvers. Highly reflective louvers are not suitable as they reflect light horizontally.

Task lights and spotlights that are not turned off during projection must also have either internal cutters or external barn doors to enable illumination of people near the screen, while preventing direct light falling on the screen.

Figure 3: This Philips Selecon PL1 LED Luminaire, is a modern LED Spotlight light fitting which provides the beam control needed for presenter lighting without excessive spill while significantly reducing the impact of our activities on the

environment. Image supplied courtesy of Philips Selecon.

4.4.3 Light Fitting Placement

The placement of lights in relation to the projection screen(s) is another critical aspect of lighting design for teaching and presentation spaces.


Near the projection screens, house lights, stage lights and lectern spotlights must all be carefully positioned to avoid spill on the screen taking into account their beam cut-off/shielding angles. This should be confirmed in the computer modelling during the design stage and not left until the lights are installed. Care must also be taken when placing spotlights to that the body of the spotlight does impede the data projector’s beam.

The vertical positioning of stage lights and lectern spotlights is often a difficult balance between sufficient light on the presenter’s face and glare in their eyes. A commonly agreed balance is to position these lights between approximately 45 degrees and 60 degrees above horizontal from the presenter’s eye-line.

Board lights should be set back from the boards a sufficient distance to allow even coverage.

4.4.4 Control of external ambient light from windows and skylights

In the architectural design of teaching spaces with projection systems, special consideration should be given to the control of natural ambient light by limiting use of windows or skylights. Where windows or skylights are present, use of curtains or blinds or louvers to control ambient light will be required. Motorised blinds or louvers controlled by the AV system are preferable.

For videoconference rooms complete control of sunlight is essential. Even small gaps in curtains can severely reduce the quality of the image captured by the camera.

NOTE: Light from all external sources should be excluded or controlled such as to allow the attainment of the standards above with respect to spill on the projection screen at any time of day and at any time of the year.

4.4.5 Dimming

Any space where the basic functionality involves presentation technology should have lighting dimmers installed. Dimming provides a finer control of the presentation environment and can optimise the performance of other components. In large spaces, dimming can also result in more efficient use of energy. The space should have functionally different areas allocated to discrete circuits on the dimming system. In some instances, a rough dimming effect can be achieved by selective switching of fluorescent tubes in light fittings, however proper dimming remains the preferred method.

Dimming must only be achieved using appropriate dimming technology to suit the installed light fittings. Care should be taken to ensure that no flicker, audible noise, electronic interference or other undesirable artefact is evident throughout the dimming range.

4.4.6 User Controls

Lighting system should be able to be operated in either of two modes:

• Standalone - using lighting wall panel(s) • Controlled - by the AV control system

Wall mounted lighting control panels (or “Entry/Exit” switches which bring up the appropriate lighting mode) must be placed near entrances in accordance with applicable regulatory requirements and building standards.

Presenters need quick access to lighting controls located at the lectern/presentation position, consequently lighting control must also be available via the AV control system. In larger spaces this is an essential requirement.


4.4.7 House Lights

House lighting shall be directional in nature, dimmable, low spill, low glare, even and reasonably shadow-free providing approximately 320 lux falling on audience horizontal reading surfaces when operated at 100%. Currently fluorescent lighting is the most suitable for this purpose when combined with suitable low glare/spill fittings.

Lighting shall be arranged in enough zones to enable sufficient control of lighting for various projection needs and evenness lighting of the audience areas in tiered venues where the rear lights are much closer to the audience than at the front.

Fluorescent light fittings shall be of ‘rapid-start’ energy efficient type with a minimum of flicker and audible noise.

Lights shall be spaced so there is significant overlap of beam patterns (so a lamp failure does not create an unusable dark zone).

4.4.8 “Stage” Area Lights

Whether to illuminate presenters as they move around the room or for a table of speakers at a conference, ‘Stage Lighting’ provides a means of illuminating the required presentation area while avoiding washing out the projected images. Good stage lighting can help to reduce the occurrence of presenters turning on the board lights simply to get enough light while projecting.

Whether to illuminate presenters as they move around the room or for a table of speakers at a conference, ‘Stage Lighting’ provides a means of illuminating the required presentation area while avoiding washing out the projected images. Good stage lighting can help to reduce the occurrence of presenters turning on the board lights simply to get enough light while projecting.

“Stage” lights must be dimmable narrow-beam directional lights with excellent control of spill. They should include devices such as barn doors or cutters to accurately shape the light beam to avoid spill on the projection screen while at the same time lighting as much of the area in front of the screen as possible. For smaller venues the principle of providing lighting with strong spill control near the screen is just as valid. In this context it may be achieved with a series of small down lights or directional fluorescent lights with highly effective louvers.

4.4.9 Presenter Spotlights

In lecture theatres and large venues, a minimum of two narrow-beam focussing spotlights shall be installed to light the presenter at the lectern. The spotlights shall have full beam control (zoom, focus and cutters or barn doors) to adjust the light coverage and minimise spill onto the screens. Care shall be taken to avoid reflections off the lectern surfaces. For large venues theatrical spotlights are suitable.

In smaller venues a range of cost effective low voltage fittings can be used. A compact fluorescent asymmetric wall washer recessed in the ceiling can also be effective as long as care is taken to position it well and direct its beam well clear of the projection screen.

4.4.10 Special requirements for Video Conference spaces

Video conference venues are in effect small television studios and require additional care and consideration in lighting design. It is important to minimize shadows, eliminate glare, avoid reflective surfaces and to create an evenly lit environment.

The best general lighting for videoconferencing is diffuse fluorescent. However even fluorescent lights will cause unattractive shadows around the eyes of participants if placed directly overhead. When carefully placed fluorescent asymmetrical wall washer light fittings can provide an even light at a 45-degree angle that reduces eye shadowing. Small spotlights carefully applied can provide


pleasant shaping and highlights to the participant’s faces. For consistency of colour and skin tone reproduction by the camera use lights of the same colour temperature (e. g. 4000 Kelvin) and ensure illumination of participants' faces at around 500 lux.

Ideally, the room should not have any exterior windows. If it does, they need to be fully covered with curtains or blinds. Even a small chink of sunlight in the background can cause problems for the camera. Backgrounds and table tops should not be too dark or too light as this can cause difficulty with camera auto-iris control. Mid tones and moderate lighting levels on background walls will give the best results. Avoid patterned or woven fabrics and finishes on walls as these can produce moiré patterns or strobing effects when the camera is moved.

4.4.11 Integration with AV Control Systems

The dimmer network must have either a serial or IP interface and be connected to the AV control system via either serial or IP network cabling.

The AV control system must be programmed to provide quick access to lighting pre-sets and user accessible slider/fader controls for spot and stage lights. The AV control system can also automate some functions, such as dimming board lights or closing motorised blinds when projection is selected.

Lighting levels shall be fully and continuously controllable from 100% light output to less than 2%. Control function (i.e. control input versus light output) shall be approximately linear.

No occupancy time out and user initiated lighting and AV system shut down routines must be programmed. The desired lighting and AV system actions at each stage of the routine should be documented and agreed upon by stakeholders.

4.4.12 Dimmer Location

Dimmers should be located in positions that facilitate easy access. They should not be located in ceiling cavities or in false floors. Within the cupboard dimmers must be mounted at a height which allows ready access for a standing technician, without using a ladder or having to crouch or kneel down. The operation of the dimmers must not cause electronic magnetic or any other kind of interference with other systems within the room or in the vicinity.

In venues with a bio box the dimmer(s) shall be installed in or near the bio box to facilitate control wiring and adjustment.

4.4.13 Fire, Emergency, Mechanical Services (A/C) and BMS integration

Where required the AV and lighting system shall be installed and programmed to accept signals from the buildings emergency warning system (EWIS). An emergency signal to the system should trigger the actions determined by regulation e.g.: turning on the lights, muting sound systems other than warning announcements etc.

In many cases it is desirable to connect the room control system to the Building Management System (BMS). This allows the room automation to send signals to the air conditioning regarding lighting states and room occupancy.


5 Displays, Specifications and Sightlines

The type and the size of the display is critical to the installation to ensure the audience are able to read detailed content on the screen from wherever they are seated in the venue.

All display devices must have a minimum native resolution of 1920x1080 and an aspect ratio of 16:9 with the only exception being ultra-short throw projection, which may have a lower resolution of 1280x800. Any additional displays mirroring the output of an ultra-short throw projector must be of the same aspect ratio.

The screen is not to be too low as to be obscured by objects or other participants in the audience. In some instance the actual height of the ceiling may pose an issue in the design and installation of an appropriate size screen when taking into account the actual size of the room and distance of the furthest audience member from the screen. In these instances, further discussion will be required with Flinders University ITS AV to ensure a satisfactory result is obtained.

5.1 Single Display

The images/screens are to be cantered as close as practically possible to the room centre line allowing uninterrupted viewing for the audience from anywhere in the room.

Final screen position will be determined during the design consultation process and any variation to this will not be accepted unless written permission is supplied by Flinders University ITS AV before installation.

5.2 Dual Display

The presentation of two independent images is now common in medium to large teaching venues allowing the presenter independently display two unique, but complementary sources. As an example a presenter may display their laptop on one screen with a problem or question while showing the works on a document camera to a second screen. Additionally, it may be used for videoconferencing displaying both the remote site and presentation content.

Dual Display in major teaching spaces is also a fall back in the case one projector may fail.

5.3 Projection

5.3.1 Multimedia Projectors

Projected image is to provide an acceptable legible image taking into account the brightness of the projector, the physical size of the projector screen, the distance of the projector to screen and the ambient light on the projector screen itself.

Projectors shall be installed at a distance to fill the entire projector screen from edge to edge and in the centre of the projectors zoom range.

In all major teaching spaces, the projector is to be laser based technology for ease maintenance and longevity of operation. For smaller venues and where the projector is easily accessible for service and maintenance, a laser based projectors is the preferred technology however a lamp based projector may be substituted if required.

Where IWB (Interactive Whiteboards) are utilised, only ultra-short throw type projectors are to be used to reduce glare and are to be a 16:9 or 16:10 aspect ratio, a minimum of 3000 ANSI lumens and are to be wall mounted.

Projectors must be controllable with two-way communication from third party control systems such as Crestron, Extron or AMX via RS232 or Ethernet.

Flinders University ITS AV has preferred models of projectors which must be adhered to. An alternative or variation to these will not be accepted unless written permission is supplied by Flinders University ITS AV prior to installation.

5.3.2 Projector Mounts

Projector ceiling mounts must be of a suitable professional grade universal product appropriate to support both the physical size and weight of the projector. Final choice of bracket will be at the discretion of Flinders University ITS AV with samples to be provided on request.

The projector ceiling mount is to be of white powder coat finish with a universal mount and where possible a security or lock option for securing the projector. Two keys are to be provided for any locking mechanism keyed to #. All the projector mounts adjustable settings are to be firmly tightened.


Ultra-short throw projectors are to be wall mounted only and to be installed with the supplied manufacturer’s bracket to ensure optimal alignment and image quality.

Projector mounts brackets must be mounted in accordance with the manufacturers’ specifications. Mechanical (projector cages) and electronic security (tamper switches) may also be required. This will be specified during the design consultation process by Flinders University ITS AV.

When installing a projector and projector ceiling mount, it must be installed in accordance with the manufactures instructions and calculations.

Careful consideration must be given to: • Projection distance to determine screen size • Projector height in relation to optimal projected image on the screen but not to interfere

with audience sight lines. The digital keystone of a projector will not be accepted unless written permission is supplied by Flinders University ITS AV prior to installation

• Physical size and weight of the projector • Structural support for the fixing of the projector mounts in ceiling • Does not obscure sight lines of any existing or new cameras used for recording or streaming.

Flinders University ITS AV has preferred models of projectors mounts which must be adhered to. An alternative or variation to these will not be accepted unless written permission is supplied by Flinders University ITS AV prior to installation.

5.3.3 Projection Surfaces

For larger teaching, meeting and event spaces Flinders University have a preference for using large surfaces, especially in environments requiring video conferencing. The selection and placements of the screen must be governed by the size of the room and the sight line rules as for projection screens. As an example a 65” (165 cm) diagonal screen will suitable for participants sitting no further than 4.5 metres from the display.

5.3.3.1 Painted Projector Surface For large or major venues, a painted projection surfaces is recommended however it needs to be physically flat and painted with and pure white matt finish paint or the preferred option of projection screen paint such as Screen Goo or similar. Additionally, the projection surface must be perpendicular to the audience and free from power and network outlets, light switches, joins, etc. in the actual projection area.

The final dimensions of any projection area will be determined by Flinders University ITS AV during the design consultation process.

5.3.3.2 Fixed Frame Screen A fixed frame screen has many similar properties to a painted surface and offers the best lay flat properties. Fixed frame screens include a metal frame creating a border for the image and a unity white PVC surface with a gain of 1.0.

5.3.3.3 Whiteboards and Interactive Whiteboards Generally, whiteboards are not recommended as projection surfaces because they are highly reflective and cause unacceptable glare from ambient light and hotspots from projectors. If a whiteboard or an interactive whiteboard is to be the projection surface, only an ultra-short throw projector is to be used.

Where an interactive white board is installed the top of the whiteboard is to be a maximum of 2100mm above finished floor level with the bottom edge being 850mm above finished floor level depending on board size. All interactive whiteboards must be mounted in accordance with the Disability Discrimination Act 1992 and Flinders University Disability Access guidelines.


5.3.3.4 Motorised Projection Roller Screen Motorised roller screens are preferable for smaller venues allowing screens to be installed forward of whiteboards either mounted off the wall or from the ceiling. The screen surface itself is to be unity white, black backed, 50mm black border with a gain of 1.0. Motorised screen must be either controlled via IP, contact closure or wired IR.

In new building installations or wherever possible, the motorised screens are to be installed in purpose built pre-fit screen boxes to maximise screen height and terminate electronics in ceiling cavity or bulkheads.

5.4 Flat Panel Displays

For smaller teaching and meeting spaces Flinders University have a preference for using large format LCD, especially in environments requiring video conferencing.

The selection and placements of the flat panel display must be governed by the size of the room and the sight line rules as for projection screens. As an example a 65” (165 cm) diagonal screen will suitable for participants sitting no further than 4.5 metres from the display.

All flat panel displays must be controllable via IP or RS232; infrared control will not be acceptable in fixed installations.

Flat panel displays are to be installed at approximately 900 -1000 mm above finished floor level to the bottom edge of the display.

5.4.1 Interactive Flat Panel Display

Interactive flat panel displays are becoming more common in office areas across Flinders University allowing the presenters to interact with the screen at the front of the room rather than be locked down to the computer location.

In larger theatres, these interactive screens are generally located on the wall at the front of the theatre or on the teaching podium allowing the presenter to annotate on the smaller screen and mirrored on the large room display screen.

Additionally, interactive flat panel displays are installed for digital signage and wayfinding.

Interactive flat panel displays are to be installed in a location and at a height allowing access for all touch features to be accessible by wheelchair users. The interactive panels are to be installed at approximately 900mm above finished floor level to the bottom edge of the interactive display.


Direction from buildings and property and consultation with disability services should be adhered to for interactive digital signage installations.

Flat panel display mounts being either floor; wall or ceiling should be of a high quality professional grade product and must be installed as per the manufacturers’ specifications.

When selecting an appropriate bracket for mounting a flat panel display, consideration must be given to:

• the size of the display • the weight of the display • the structure supporting the display • the distance off the wall • any hardware being installed behind the display which may require access for servicing.

When mounting the flat panel display on a gyprock wall and suitable anchor points cannot be located to secure the displays mounting bracket, the audio visual integrator is to provide a solid MDF backing board finished in a suitable colour as specified by Flinders University ITS AV with edge trimming.

Mechanical and electronic security may also be required. This will be specified during the design consultation process by Flinders University ITS AV.

Final product selection and mounting position will be determined during the design consultation process and any variation to this will not be accepted unless written permission is supplied to Flinders University ITS AV before installation.

5.4.2 Flat Panel Display Trolley – MoCoW

A MoCoW (Mobile Computer on Wheels) is portable technology such as LCD trolleys with a wireless keyboard and mouse to enable flexible use of small spaces and provides group focused classes or meetings. This also avoids fixed hardware allowing for movement in and out of rooms.

MoCoW technology is often changed or improved so that any design should be first checked with ITS AV to ensure it is meeting the most recent version of technology and the University standards.

6 Control

6.1 Integrated Control Systems

Flinders University fully support and recommends the use of integrated control systems where AV has been deployed to simplify operation as well as provide the ability for remote ITS AV support.

Across Flinders University the integrated control equipment is exclusively Crestron unless otherwise specified by Flinders University ITS AV. Should a design require a control product not able to be supplied by Crestron any variation will not be accepted unless written permission with relevant data sheet is supplied to Flinders University ITS AV before the design is approved and installation can be arranged.

Minimum standard requires the control system to perform the following actions: • Control of local audio visual equipment to include

o Power On/Off o Inputs Switching o Volume Up/Down o Status reporting

• Control of mechanical devices, i.e. Screens, curtain, blinds • Power management • EWIS integration.

For best practice the integrated controller should perform: • Control of local audio visual equipment to include

o Power On/Off o Inputs Switching o Volume Up/Down o Transport Control o Status reporting

• Screens, curtain, blinds • Lighting – dimming/switching • Power management • EWIS integration • Status Reporting Error Logging • Remote Monitoring and Support.

Functions should be automated in such a way that a single button press should be able to activate all the AV in the room into an ON Status, including switching on the display, lowering a projector screen, adjusting the volume to a predetermined default level and switching to the default device input.

Where possible all control systems will be networked and on the Flinders specified network for additional security and management purposes.

6.2 Control System Touch Screens Interface

Touch screens shall be provided and interfaced to the equipment control system for AV teaching, meeting and event spaces across Flinders University.

The touch screen design is to conform to the University wide standards, to maximise usability and minimise the need for specific training.

An ongoing provision should be provided, at no additional charge, for the revision of the control interface and programming functionality after practical completion for a period of up to six months.


Figure 6: Sample Touch Screen Layout

6.3 Control System Button Interface

Button Panels may be used as an interface to control AV in basic teaching rooms, meeting rooms, event spaces and mobile trolleys across Flinders University.

The button panel shall be capable of controlling all equipment specified. The contractor shall design the layout of buttons and controls on this touch screen using the approved Flinders University layout.

For best practice the button controller should perform: • Control of local audio visual equipment to include

o Power On/Off o Inputs Switching o Volume Up/Down

• Control of mechanical screen.

6.4 Control System Programming Code

6.4.1 General requirements

Flinders University has requirements for AV programming that must be adhered to. These requirements ensure the code produced by the Integrator is of a consistent and high quality in design and operation. It facilitates simple understanding of the code for maintenance and enhancement. The University also has developed a standard Smart Graphics touch panel template that must be used to provide a consistent user interface across the University. This standard interface can only be altered by means of written consent from Flinders University ITS AV.

All Crestron control systems are to include an XPanel that is a mirror of the touch panel/keypad in the room for remote management purposes.


The complete source code for all projects undertaken must be provided to Flinders ITS in an electronic format, e.g. USB memory stick, CD, email attachment etc. This must include all files used to build the room from source:

• Crestron source • Un-compiled modules • touch panel source files • device configuration files – e.g. DSP, Switcher • IP information • User guides • ‘As Built’ design including schematics and floor plans detailing:

o Equipment – Make and Model o Connection type – RS232, LAN, HDMI, DVI, Balanced Audio, etc o Cabling – Make and model o Labelling of cables – as per the actual installed cabling

Schematics shall be in CAD, DWG, Visio and an additional PDF version must be created.

This information is required immediately following Practical Completion and prior to signoff of works as complete.

6.4.2 DNS Naming

All TCP/IP device references in the code must use the DNS name of the target device as opposed to the TCP/IP address. Flinders ITS AV will provide a spreadsheet to be filled in by the Integrator during commissioning which includes details on the devices and their MAC addresses to allow IP address allocation. All devices which can be set to DHCP for their IP information should be done so and any exceptions noted in the IP spreadsheet.

All references in IP tables and code should use the DNS name of the device. This will allow Flinders ITS flexibility in moving IP addresses of AV assets without having to recompile code.

6.4.3 Working Code Example

A working example program showing design, structure and features required by Flinders University is available upon request to ITS AV. This code includes the Flinders standard touch panel file which should be used as a basis for all future rooms. Crestron source code is included that demonstrates a complete standard meeting room. The code also demonstrates the Crestron Fusion requirements for Flinders University, which are detailed in the Error! Reference source not found. section.

6.4.4 Crestron Fusion

Flinders University uses Crestron Fusion to remotely manage and collect statistics on its AV enabled spaces. This must be implemented in a consistent manner in the Crestron room code, as changes may affect the entire of the University. When a symbol is added to Fusion, if the joins are not previously defined, the name of the join is added to the master list in Fusion. All other references to this join from here on use this same name reference. If subsequent symbols use a different name, the internal working of the room will continue to work correctly, but Fusion will incorrectly reference the join.

6.4.4.1 Standard Joins There should be one Fusion Room symbol per room. For systems which control more than one room from the same processor an individual Fusion Room symbol is required for each controlled room.

The Room symbol contains many predefined joins and some of these are implemented in our system. There are also ‘custom’ fields which are also defined by Flinders and used. These fields implicitly start at Join #50 and the standard ones are defined below.

55 Input UPS Status Used to relay pre-defined text from Fusion module for UPS status

56 Input Mic Status Used to relay pre-defined text from Fusion module for Mic status

57 Input Projector Status 1 Used to relay pre-defined text from Fusion module for Projector status




6.4.4.2 Device Usage Flinders University implements the Device Usage component of Fusion as part of its efforts to best understand room usage. The Fusion Device Usage symbol is used to collect this data and must be implemented in all Crestron AV controlled spaces. This component also requires standardised naming conventions to ensure sources can be aggregated and compared across spaces.

The Serial join component of the Fusion Room symbol also includes the Current Source for each display device. Strings to this component should also follow the same standardised naming convention, shown below.

6.5 Device Communications

Where possible Flinders University prefers communication to AV devices via TCP/IP rather than serial (RS232) or IR. TCP/IP offers the fastest means of communications and is standard on most equipment. Further, it is preferred that communications to devices be implemented via protocols not specific to a manufacturer, where possible. For example, where a display device implements the PJLink protocol it is to be used in preference to the manufacturer’s dedicated protocol. This is to allow similar devices to be substituted without code changes being required.

The preferred control communications endorsed by Flinders in order are: 1. Ethernet Control (IP Based) 2. RS-232 (via dedicated cable) 3. RS-232 (via DTP/XTP/Digital Media) 4. Contact Closure 5. Wired IR (Projector Screens)

6.6 Device Security

Flinders University implements several layers of security around its network connected AV assets. Firstly, all AV assets are assigned a separate network VLAN and IP range. This helps isolate the AV network against most users. Flinders ITS AV will assign appropriate VLANs on the network points/switches at time of commissioning.

All AV assets must also be secured to the best of the abilities of each individual device. Flinders preference is for encrypted communications to a device, using passwords supplied by Flinders ITS, and for unencrypted/unsecured communication methods to be disabled. As such use of the Crestron SSH communications module is advised.

Note that device security should include all forms of communications. As such if the device offers another interface e.g. web page or ftp, it should also be secured and encrypted if possible.

All implemented passwords should be recorded and returned on the (supplied) Flinders ITS IP Spreadsheet as part of the handover package at the conclusion of commissioning.


7 Video Switching

The University utilises Extron switching equipment for all it teaching, meeting an event spaces. Any space that has been designated to be converted from analogue to digital, or any space that is designated to be configured to output High Definition, will require the use of a High Definition Digital HDMI switcher/matrix. The switcher will be capable of:

• HDCP compliance with full key management on all inputs and outputs • EDID management • Scaling/frame rate conversion • HDMI Audio embedding and de-embedding • 1920x1080@60Hz • Colour space management.

Where display devices do not natively support 1080p, such ultra-short throw projectors, a video scaler is to be incorporated into the design to manage all the video endpoints in the space.

Audio resources from devices such as PCs, laptops, Blu-ray, wireless presenter, etc. are to be transported digitally via HDMI and routed as required through vision switcher.

Any variations requiring more switching capability than provided as the listed solutions must be approved by ITS AV before the commencement of works.


8 Audio

Audio will be provided in any meeting room or teaching room with video displays in the room. A purpose designed audio system for each individual venue is to be installed with an adequate sound level with high intelligibility across the entire space free from noise and distortion.

In teaching spaces, a designed audio system shall provide the following functionality: • Voice re-enforcement • Replay of program sources • Assistive listening/hearing augmentation • Lecture capture (where required).

Key audio components for a major teaching space will comprise of: • High quality speakers installed as to provide uniform coverage of the listening area • Lectern microphone with provision for additional microphones if required • Hand held and lapel radio microphones • Audio mixer to enable signal routing, level control, limiting/compression, microphone

equalisation and line level audio sources. The audio mixer is to provide any phantom power for microphones, interface with the integrated control system and provide an output to the amplifiers, lecture record and to the local PC

• High quality audio amplifier with load protection • Assistive listening system such as an induction loop, Infra-Red or RF systems.

8.1 Loudspeaker and Coverage

Typically, an audio system will consist of suitable stereo front of house (FOH) speakers supplemented with flush mounted ceiling speakers, if required, suitably positioned throughout the space. Final size and the position of all speakers must be determined in consultation with Flinders University ITS AV during the design process.

Wall mounted speakers are to have brackets fitted allowing adjustment of the speakers in both the horizontal and vertical plane and allow the speakers to be locked into position.

8.2 Microphones

In all major teaching spaces and meeting places an optional wired lectern or podium microphone may be installed.

A wireless microphone as a minimum will be installed in every teaching space for the Assistive Learning System. If a teaching space is equipped with Lecture Capture/Record, a radio frequency lapel microphone will be installed for the presenter with a radio frequency hand held microphone for audience questions and as a backup for the lapel microphone. All wireless microphones are by default to include a table charging station sufficient for each wireless microphone in the room.

The wireless microphone transmission frequency must be compatible with Australian audio frequency standards and should be operated within a legal radio frequency range, clear of 3G/4G telecommunication transmissions, digital TV transmissions, and free from local interference. Ideally the units operate within a selectable range of frequencies appropriate for Australia.

Flinders University has a selected range of frequencies that have been mapped for use at Bedford Park and Victoria Square campus. When installing new wireless radio microphones, ITS AV will provide the AV contractor the wireless microphone frequency to use in the room and must not be deviated from.

Were possible, all wireless microphones transmitters and receivers should be encrypted if the product is compatible.


8.3 Hearing Augmentation

Installed hearing augmentation/assistive listening systems at Flinders University shall be in accordance with AS60118.4-2007 standards and Building Code of Australia BCA 2011.

The hearing augmentation systems shall be professionally designed and installed by contracted experts with test results, for audit purposes, that the installed system meets or exceeds the current standards.

The supply and installation of any hearing augmentation system into a teaching space is to comply strictly with the following:

• Hearing augmentation system must be installed in all teaching spaces with audio visual systems and all major public accessible venues with audio re-enforcements and shall be clearly labelled with appropriate signage

• The type of hearing augmentation system to be installed is based and the venues individual variables as meeting rooms and classroom are often closely adjacent and special care must be taken as to ensure that coverage fields do not overlap.

For new buildings an ultra-low spill under carpet inductive loop is the preferred option however in the situation of many Universities, classrooms are often adjacent and special care must be taken to ensure coverage fields or hearing augmentation systems do not overlap.

Other hearing augmentation technologies include infrared and RF systems

8.4 Audio Mixer

ITS have standardised on DSP (Digital Signal Processor) for processing and routing audio inputs and outputs across all its teaching spaces.

The audio mixer will accommodate combinations of microphones, providing phantom power as required, and balanced and unbalanced audio signals.

The size and the type of audio mixer shall be determined on the required amount of inputs and outputs however additional outlets are required for any future expansions. Typically, an audio mixer will have two free input and two free outputs for future usage.

Typical inputs into audio mixer include but not limited to: • Wired and wireless microphones • Sources devices such as PCs, Blu-ray, laptops, video conferencing codecs, external audio

feeds • Video switchers.

Typical outputs from the audio mixer include: • Program audio left/right room • Speech out • Program re-enforcement delay channels • Videoconference output • Lecture capture output • Recording output • External feeds.

8.5 Audio Amplifiers

All audio amplifiers are to be a high quality power amplifier matched to the power requirement of the installed speakers and are to be of appropriate power to provide sufficient sound levels for the audience.


The installation of the audio amplifier requires careful consideration in its location taking into account heat generation and ventilation. Heat generation may affect the operation surrounding equipment therefore sufficient ventilation and physical space is to be adhered to.

8.6 Source Equipment

Source equipment is audio visual devices which aid the presenter during the presentation such as a PC, laptop, document camera Blu-ray player, etc. Source equipment will be individually specified for each space in consultation with Flinders University ITS AV during the design process. Typically, these units are readily and easily assessable to all users and may require additional mechanical or electronic security measures as deemed suitable by Flinders University ITS AV.

8.6.1 Resident Computer

The resident computer will be integrated as part of the installation generally in the lectern joinery. The monitor, keyboard and mouse are to be hardwired to rear USB ports of the computer. Velcro stripping will ideally be used to secure the pc to shelf firmly in place but still be able to be removed for servicing or swap out.

In some instance there may not be joinery, such as meeting rooms, therefore a resident microcomputer may be installed on the wall adjacent or just behind flat panel displays.

Easy access is required to the resident computer by the user to install media such DVDs, USB drivers or to switch the unit ON/OFF from the power button.

Resident computers shall be free issue by ITS and will be imaged with either a Lecture Theatre Image or Meeting Room image depending on their location and their requirement.

A standard laptop provision will include as a minimum: • a GPO for powering the portable device • a wired network connection • a HDMI connection.

Both the HDMI and wired network cable will include pull through cables with sufficient length to connect devices without tension on the cables.

8.6.3 Document Cameras

The visualisers or document cameras have to a large extent replaced the overhead projectors and are now controlled from the integrated control system for ease of use. Document cameras enable the presenter to display printed documents, handwritten annotations and 3D objects.

Document cameras are installed across all Flinders University teaching spaces and are to include: • 1920x1080p native resolution • Light sources • HDMI output • RS232 or LAN control • Optical zoom.

8.6.4 Wireless Presentation Tools

A professional wireless presenter tools allows a presenter or student to connect they BYOD devices such laptop, tablet, smart phone, etc. to the local display in the room via the Flinders Wireless network and maybe either a hardware or software solution.

Wireless presenters installed across Flinders University teaching spaces and are to include: • 1920x1080p native resolution • LAN Control • HDMI Output

Apple TV are not to be used as a wireless presentation device and are not to be connected to the Flinders University network without strict instruction from both the ITS security team and ITS Network Infrastructure team.

8.6.5 Blu-ray Player

Blu-ray/DVD players are generally only installed in major teaching spaces but maybe integrated into other teaching, meeting and event space as required however multi-region capability needs to be considered.


9 Lecture Capture Recording Systems

The Lecture Capture Recording System records lectures and events in supported venues to be made available to digitally view live lectures or events or to access the recordings at a later time. Recordings are made available to students as streaming video, via the FLO (Flinders Learning Online).

The lecture capture recording generally consists of:

Screen Capture

Ability to digitally capture any content being displayed on the room display which may include the room PC, BYOD device, document camera, wireless presenter, etc.

Please note that any digital media content that is Copy Protected may be displayed in the room however it cannot be recorded as part of lecture capture stream.

The video switching shall output a native 1920x1080p HDMI signal for the lecture capture recording.

Audio Capture

Audio recording is possible under the lecture recording system. A line level output containing a post fade mix of all microphone and line sources should be available under the audio switching and mixing specification.

Depending on the type of capture hardware, the audio output required maybe either a balanced or unbalanced and shall be determined at the time of installation.

Camera Provision

Where camera recording is possible under the lecture capture system in use, a suitable camera position shall be identified and provisioned with double power, data and video tie lines. The chosen position will have an unobstructed view of the entire teaching presentation area at an angle of view no greater than 15 degrees vertically and 30 degrees horizontally.

Typically, a lecture capture camera is PTZ with simultaneous IP and Video Streaming and IP and serial control.


10 Physical Requirements for Teaching Spaces

10.1 Equipment Racks

11.4 Electrical Testing & Tagging

The audio visual contractor is to have all supplied AV equipment including power leads, tested and tagged by a licensed electrical equipment tester as per AS/NZ3760:2003 standards prior to installation. The contractor shall supply FU with the following on a USB memory stick:

• Equipment type and serial number • Equipment location i.e. building room and number • Equipment test date • Name of tester.


12 Video Conference Facility Design Standards

Flinders University video conference hardware codec as standard is the Cisco SX series however there are still instances Cisco C20, C40 and C60 codec installed in meeting rooms and teaching spaces.

All units are purchased with premium resolution and dual display options enabled.

12.1 Physical Requirements for Teaching Spaces/Meeting space

12.1.1 Equipment Racks

Video conference equipment is typically mounted in standard 19-inch racks. Racks must provide convenient access to the front and rear of equipment. All equipment, where possible, shall have rack ears for mounting. If equipment is not suitable for rack mounting a minimum of a 1RU cantilevered shelf shall be provided to support each individual piece of equipment.

It is recommended that Cisco video conference end points are positioned at the highest position in the rack possible with no other equipment above and space below as this unit will produce considerable heat, this and will allow sufficient heat dissipation.

12.1.2 Camera Mounting

Video conference systems will require at least one camera to be mounted in the space to capture local participants to send to the connected sites.

In a meeting space with a central meeting table the camera should be mounted between the two display screens at eye line of the participants. This is usually at a height of 1.2m from the floor and centrally placed between the two displays or below a single display level with the bottom edge of the displays.

In a lecture theatre environment, the camera is placed centrally between the two displays and may be higher than in a meeting room as displays are generally higher on the wall to be seen by all people in the auditorium. This camera is to capture the audience allowing the far end to see all participants for a far end presentation or open discussion. In a lecture theatre it is standard that a second camera is placed at the rear of the room at approximately 2.2m from the floor to capture the presenter at the front of the theatre giving a presentation to the local audience and the connected sites remotely.

12.1.3 Dual Display

As content presenting is available to be shared between local and remote sites in a video conference it is standard that all Cisco SX series endpoints are purchased with the dual display option. Installation in the space can be a number of possible options depending on the space and the user requirements.

Types of displays include: • Dual projection • Dual LCD panels • Dual interactive white boards • Interactive white board and LCD panel • Projection and LCD panel.

In meeting spaces, it is recommended that LCD panels be mounted 1.2m from the floor to the base of the panel for best eye line of seated participants. In lecture theatres the recommended height is dependent on the size and layout of the space and is defined on a case by case basis.


12.1.4 Audio and Microphones

Clean audio free of echo is extremely important in a video conference setup. Audio in the space needs to be carefully considered to eliminate any additional noise. In a more complex environment it may be needed to engage an outside professional acoustic engineer to supply an acoustic report of the space and to offer recommendations.

In meeting spaces with a central meeting table a table top microphone is the standard, this is placed on the table in the room and will capture all participants around the table. The number of microphones required will be determined by the size of the room and table, as a standard a microphone will be available approximately every 3m. There will be no in room audio reinforcement from this microphone and its audio will be sent directly to the connected remote sites.

Acoustic echo cancellation (AEC) is enabled on the either the endpoint or via a hardware based Digital Signal Processer (DSP) at both the local and remote sites eliminating any signal picked up by local microphones from sound reinforcement speakers in the room. If AEC is enabled through hardware DSP, AEC settings must be disabled on the video conference codec to not interfere with audio quality.

Video conference codec Microphone inputs

C20 2 3.5 stereo mini jack + L&R RCA line

C40 2 XLR + L&R RCA line

C60 4 XLR + L&R RCA line SX10 1 3.5 stereo mini jack

SX20 2 3.5 stereo mini jack

SX80 8 Euroblock

In lecture theatre spaces multiple microphones are usually available to allow for different presentation and teaching styles.

The types of microphones include: • Lapel microphone • Table top microphone • Hand held microphone • Ceiling mounted microphone • Gooseneck microphone.

A greater number of microphone sources makes audio processing much more complex and a DSP hardware device is essential to achieve quality audio. AEC is a more complex set up as a lecture theatre space being much larger will need considerable sound reinforcement to deliver quality audio to all participants in the space.

12.1.5 System Control

The control system within a space may vary depending on the complexity of the AV system the video conference unit must integrate with.

12.1.5.1 Basic Meeting Room In the basic meeting room, the video conference unit is independent of any other AV equipment and these types of systems can be controlled with the Cisco remote control or the integrated Cisco touch panel.

12.1.5.2 Advanced Meeting Room/Boardroom The advance meeting space has additional AV sources available in the space and will be controlled by a dedicated AV control system with central touch panel.


12.1.5.3 Lecture Theatres As there are a large number of available sources in the lecture theatre environment this system is controlled via central AV control system through a touch panel.

12.1.6 Touch interface

Full functionality of the video conference system is required via the central touch panel to allow users to interact and control the video conference system.

The following video conference functionalities are required via the touch interface: • Phone books • Layout • Dial pad • Special characters (# . * @) • Presentation (share content) • Camera control (position, zoom main and second camera option) • Near end and far end control • Accept or reject incoming call • Home • Microphone mute • Volume control • Function keys • Confirmation key • DMTF dialling

12.1.8 Web Conferencing

Web conferencing options are available in meeting spaces and from staff local desktops, laptops and mobile devices at Flinders. Staff have standard Cisco conferencing tools installed on their devices and in meeting spaces to allow a variety of conferencing options.

12.1.8.1 Cisco Jabber and Jabber Guest Cisco Jabber is installed on all staff computers and in meeting spaces allowing staff to communicate through instant messaging, video calls and desktop sharing. Cisco jabber clients can connect to all standard video conference meeting room and teaching spaces allowing audio and video real time communications, they can also share desktop content. A built in camera and microphone is required via a laptop or externally connected Web camera and microphone attached to the PC via USB connection.

For directions and standards for installations of cameras and microphones refer to AV room design document.


12.1.8.2 Cisco WebEx Cisco WebEx is available on all staff computers and in meeting spaces through any available browser to join a WebEx meeting. Meetings can be schedule through staff’s Outlook or via the online portal https://meetings.flinders.edu.au

WebEx provides a collaboration environment where internal or external staff can meet in a virtual online meeting space via email invitation. Meetings can include audio and video feeds from the presenter and the participants and meeting spaces will require a Web camera and microphone attached to the PC via USB connection. Desktop sharing and control sharing is available and can be passed between participants allowing collaboration; text chat is available for continuous communication throughout the meeting.

For directions and standards for installations of cameras and microphones refer to AV room design document.

13 Digital Signage

The standard digital signage installation is comprised of a 46” LCD panel with attached PC running player software, installed in portrait or landscape orientation on a wall, ceiling or a stand. All content is controlled through a central web interface allowing publishers to schedule and upload content to attached players in public spaces and thoroughfares.

13.1 Digital Signage Hardware

The PCs are generally a Dell Micro model and are either attached to the wall behind the panel or onto the panel bracket using supplied VESA mount with a HDMI cable connecting the PC to the flat panel display.

13.2 Network Requirements

For each of the digital signage solutions two data network outlets are required at each panel location and are both terminated to the device management network allowing the content to be sent to the PC from a central location. The second network connection allows the ITS manage the flat panel display remotely.

13.3 Power Requirements

For each of the digital signage solutions two power outlets are required at each panel location for powering the flat panel display and for the signage PC.

13.4 Mounting LCD panel

The LCD panel will be mounted flush on a wall or pillar at a height that is suited for the application of the signage to allow ease of viewing for all people who may need to access the displayed information. Proffered mounting brackets will have the provision for secure locking options in the case the panel is positioned in a vulnerable public location. Proffered mounting bracket will provide ample space between the wall and the panel to allow for PC and appropriate ventilation.

In the case no wall or pillar fastenings are appropriate a pole will be fastened to the ceiling dropping through the tiles and the LCD screen will be attached to this pole, the pole will have adequate provision for all cable management internally.

If no fastenings are appropriate in the space to existing surfaces a free standing option is available to mount the LCD panel and to place the system in the best position for viewing by people in the space. One area that needs to be address with this option is cable management if the stand is away from walls cables must not pose any tripping hazard.

13.5 Touch Enabled Flat Panel Displays

For interactive content the LCD panel will be fitted with a touch enabled overlay allowing viewers to interact with content by touching the screen.

Mounting options for interactive flat panel displays are to allow access for all touch features to be accessible by wheelchair users and panels must be mounted at 1.2 from the finished floor level to the bottom edge of the LCD panel. Direction from buildings and property and Counselling and disability services should be adhered to for interactive digital signage installations.

13.6 Outdoor Signage Solution

There is on occasion the requirement for an outdoor signage solution, either fixed to a wall or as a free standing installation with an appropriate all weather housing and outdoor rated ultra-bright LCD panel (IP65 rated).


Consultation with ITS and Buildings and property is required and each installation will be done on a case by case basis.

13.7 Enterprise Signage System

Flinders enterprise wide digital signage solution is an html 5 web based interface controlled and administered through ITS and integrated with Flinders active directory. Any Flinders staff can access the system on request and will be granted publisher access to send content to specific players across Flinders campuses assigned to their area. Approved users can upload, schedule and publish content via a web interface from on or off campus pushing content to LCD panels for viewing.

All content is cached on the local player and if there is a network interruption local content will continue to be displayed until network access is restored.

There are no restrictions on the number of users of the system or the number of players attached to the system allowing unlimited expansion across the University.


14 Audio Visual Assets Standards - Information Security and Risk

14.1 Purpose

The purpose of this standard is to define requirements for the secure configuration of audio visual systems that are owned and operated by Flinders University. The effective implementation of this standard will minimize unauthorized access to University audio visual equipment.

14.2 Scope

This standard applies to all audio visual equipment that is owned and/or managed by Flinders University. This includes all controlled AV devices in teaching spaces, meeting spaces, and public areas.

14.3 Definitions

Audio Visual (AV) systems are composite systems of devices that are used for projection of audio visual content. These systems are in use in teaching, meeting, mobile and public spaces throughout the University. They are often automated via a touch panel to provide a simple, consistent user interface.

14.4 Roles and Responsibilities

The following University members have specific responsibilities to adhere to this standard:

Director, Information Technology Services (ITS) is responsible for the approval and communication of this standard.

Information Security and Risk are accountable for monitoring and enforcing compliance with this standard.

Manager, Unified Communications Services is responsible for ensuring that system administrators under their supervision fully understand this standard and comply with its requirements.

Video Conferencing and Audio Visual Services & Client Computing Services are responsible for the implementation of this standard and ensuring all audio visual standards are applied to all relevant systems across the University.

14.5 Audio Visual Standards

The following standards must be adhered to when deploying audio visual systems. Each and every standard may not be applicable to all audio visual systems; therefore, any deviations or exemptions to this standard must be documented and approved by the Associate Director, Information Security and Risk.

14.5.1 Authentication Strategy

• Audio Visual Services must develop a standard security plan that incorporates a tiered password specification (to cater for different device capabilities), and device configurations

• Audio Visual Services must develop and document implementation procedures for common Audio Visual systems

• Audio Visual Services must communicate these procedures to AV integrators working on behalf of the University to ensure AV assets are secured and conforming to Flinders security policies.


14.5.2 Configuration and Connectivity

• All AV devices that support DHCP should have DHCP enabled. ITS will create DHCP reservations and DNS entries to support all AV equipment. AV devices should be referred to by their DNS name when creating TCP/IP connections between devices

• All AV devices will be commissioned on the University’s Device Management networks to allow isolation from the general staff/student traffic

• All Integrators of Crestron AV systems must provide an XPanel interface for remote management of the space. This XPanel will be uploaded to the ITS Wiki for easy access

• Authentication must be enabled on all AV assets that support it • Default accounts must be removed/disabled or their passwords changed to a value unique

to all audio visual systems and stored in Flinders password store • Guest accounts (if any) must be disabled • A separate account for device control should be created where supported by the device • Control methods that are not specific to a manufacturer should be preferred, e.g. PJLink for

projectors • All devices must be updated to the latest stable version of firmware at the time of

commissioning.

14.5.3 Operations and Maintenance

• Remote access for any maintenance or troubleshooting activity must be over secure channels, (e.g. encrypted network connections using SSH with high encryption, 128bit encryption or greater) using privileged accounts, where the device supports it)

• Where possible remote access interfaces must only be accessible to ITS Support networks to prevent users from accessing such interfaces

• Audio Visual Services must monitor for common vendor firmware updates that address critical security weaknesses

• Vulnerabilities in AV equipment will be monitored as part of the Vulnerability Management Standards and the AV Team alerted when a major security issue is found. The AV Team should then arrange for systems in danger to be updated either by support staff or a preferred AV Integrator

• Any changes or updates to the standard security plan must follow the regular change management procedures that include requirements for testing and approval.

14.5.4 Physical Security

All audio visual systems must be adequately secured to ensure they cannot be easily tampered with: • AV equipment racks and cupboards must incorporate a locking mechanism and kept locked

when not being maintained • Publically accessible devices e.g. located on lecterns, tables etc. should be physically

restrained to prevent theft, where this does not impede the function of the device.

15 Guidelines for Accessibility- Lecterns and AV Workstations in Lecture Theatres

15.1 Access to lecture theatre

• Ramped access to lectern (if floor not level) • 1200mm wide route to lectern (with no obstructions like desks/chairs in the way. • If lectern is not wheelchair accessible, do not fix it to the floor, but make it moveable and

have an alternative option for a wheelchair user (desk no higher than 760mm, with space underneath to fit wheelchair/legs).

Figure 8: Wheelchair Access

15.2 Circulation Space

• 1400mm x 1400mm (minimum) space behind lectern to manoeuvre wheelchair. Preferably 1500mm x 1500mm.

Figure 9: Space Allowance


15.3 Lectern Dimensions

• Height adjustable, with controls easy to reach for someone in a wheelchair • No cupboards underneath the benchtop (to allow for a wheelchair to fit underneath) • Cables/USB slots to be within easy reach (e.g. on benchtop) • Microphone • Reading Light • Circulation space for arms on the desktop: 540mm – 600mm deep, 1410mm max width • Switches: to be between 400mm and 1200mm above floor level • Storage: All items stored between 400mm and 1200mm above floor level • Emergency alarm/telephone link: to be stored between 400mm and 1200mm above floor

level.

Figure 10: Maximum Reach

15.4 Touch Screen

• Positioned between 400mm and 1200mm above floor level • Ability to change between small and large size text • Screen to be as large as possible


• If possible, offer an alternative to using the touch screen, e.g. a keyboard attached with physical buttons

• Audible tones when a button is selected (to confirm selection). Best if you had one tone for a successful selection and a different tone when a button selection didn’t work (error tones and confirmation beeps)

• Buttons to be in a consistent and logical position (same for each lecture theatre).

15.5 Screen contrast

• PCs and Macs have inbuilt accessibility options which allow the user to adjust the screen contrast

• If a screen is not a computer-based device, consider contrasting colours and large font for touch-screen buttons. EG white text on a black background or yellow text on a dark blue background

• It is recommended that the background to the device is a light colour, with the button/key a dark colour, and then the text on the button/key a light colour

• Remove unnecessary logos and pictures to simplify the screenshot.

Button size/shape/texture

• Consider all keypads, including light switches, remote controls and switches to turn on the projector and computer

• All buttons to be positioned between 400mm and 1200mm above floor level • Braille buttons are helpful for people who use Braille, but they cannot be used on touch

screens. Braille could be used on light switches or other buttons which are physical and commonly used

• Suggested colour coding for the following function keys: Red: Cancel Yellow: Clear or Correct Green: Enter or Proceed Blue: Help or Information

• Keys should not have to be pressed for an extended period of time • Keys should not require fast sequential pressing (e.g. pressing the button two or more times

in quick succession) • The force required to press each key should not be excessively high, however the force

should not be so low the keys can be accidentally pressed • Matt and anti-glare materials to be used where possible.

15.6 Lighting

• Adjustable lighting (option to dim) • Adequate lighting over a reading desk.


15.7 Hearing Augmentation Systems

15.7.1 Induction Loop

A hearing loop consists of a microphone, an amplifier and, in the place of a loudspeaker, a coil of wire placed around the room. Sound waves from the speaker’s voice going into the microphone are changed into an electric current, amplified, and then sent through the coil which emits a magnetic field in the room. The field is picked up by the “T” switch of a hearing aid, amplified, and converted back into sound. Hearing aid users sitting within the loop system can pick up the speaker’s voice or other auditory stimulus with a minimum of distortion and no background noise simply by turning on the “T” switch on their hearing aids. The loop is fully adaptable to television, radio, stereo, tape recorder or movie projector.

It is important to have signage on all lecture theatres which have an induction loop.

15.7.2 IR (Infra-Red) System

A receiver is required for each person using the IR augmentation. Batteries need to be charged and the receiver kept in a convenient and safe location.

15.7.3 FM System

A receiver is required for each person using the IR augmentation. Batteries need to be charged and the receiver kept in a convenient and safe location.
