Unit 4 Seminar/Unit 5 Review Case Study: ABC Valve Plant

Al Dauser, CPP, CFIAdjunct Professor

Tonight’s Question

• In this week’s seminar, be prepared to discuss surveillance devices including cameras, closed-circuit television, and alarm systems as described in your readings.

Unit 5 Case Study

• We will also use part of the class to go over the ABC Valve Plant case study that is due during Unit 5.

As we discuss:

• What type of CCTV system do you have where you work?

• What type of access control?• Has your system been recently upgraded?

Were you part of the process? Help select/test/etc?

Keying Devices and Systems

• Warded locks– the keyway is open and can be seen through

• Disc tumbler locks– Used as desk locks, files locks, and padlocks

• Pin tumbler– keyway, which is irregular in shape, and the key, which

is grooved on both sides – can be master keyed

• Lever locks– used in safe deposit boxes and are for all practical

purposes pickproof

Removable Cores

• Used where locks are changes often• Made to be removed if necessary

with a core key, allowing a new core to be inserted

Keying Systems• The change key

– One key to a single lock within a master-keyed system• The submaster key

– Will open all the locks within a particular area or grouping in a given facility

• The master key– Where two or more submaster systems exist, a master

key system is established• The grand master key

– One that will open everything in a system involving two or more master-key groups

Other Operating Mechanisms for Access Control

• Combination locks– have three dials that must be aligned in

the proper order before the lock will open

• Code-operated locks– opened by pressing a series of

numbered buttons in the proper sequence

• Card-operated locks– presenting a card and code to open lock

Advantages of Access Control Systems

• a. Security staff no longer need to spend hours rotating key cores and keeping detailed logs.

• b. Card keys can be programmed to function in a variety of ways.

• c. Lost cards can be deactivated in a matter of seconds.

• d. The systems often allows the hotel to keep track of the time and number of entries at a given site

Types of Card-Operated Systems

• Magnetic coded cards– contains a flexible magnetic sheet sealed between two sheets

of plastic• Wiegan Effect cards

– short-length magnetic wires embedded within the card• Optical coded cards

– contain bar codes• Proximity cards

– send a code to a receiver via magnetic, optical, or ultrasonic pulses

• Radio Frequency Identification (RFID)– radio frequency identification

Types of Card-Operated Systems (cont.)

• Biometric systems – designed to recognize biological features

• Fingerprint recognition systems – optically scan a chosen fingerprint area and compare

the scanned area with a file

• Signature recognition systems– no two people write with the same motion or pressure

• Hand geometry recognition systems – use the geometry of the hand

Types of Card-Operated Systems (cont.)

• Speaker verification systems – Uses the uniqueness of voice patterns to determine

identification and control admittance

• Eye retina recognition – systems analyze the blood vessel pattern in the retina of

the eye

• Padlocks – detachable, portable locks that have a shackle adapted

to be opened for engagement through a hasp or chain

Types of Card-Operated Systems (cont.)

• High-security locks• iButton – an extension of the “smart card”

technology being used by the banking industry

– contains a hermetically sealed computer chip in a stainless steel container

Locking Devices

• Electromagnetic locking devices – hold doors closed by magnetism

• Double-cylinder locking devices – installed in doors that must be secured from both sides,

requiring a key to open them from either side– most common application is in doors with glass panels

• Emergency exit locking devices – panic-bar installations

Locking Devices (cont.)• Recording devices

– provide for a printout of door use by time of day and by the key used

• Vertical throw devices – lock into the jamb vertically instead of the usual horizontal bolt

• Electric locking devices – activated remotely by an electric current that releases the

strike and thus permits entrance • Sequence locking devices

– designed to ensure that all doors covered by the system are locked

Effective Surveillance Systems

• Should produce an identifiable image of persons engaging in criminal behavior

• Sequence cameras record still pictures at regular intervals

• Motion picture cameras using high-speed 16 mm film and fast shatter speeds can be set up to take pictures in normal light

• CCTV systems coupled with recording equipment or computers should be used

Technological Advances In CCTV

• Reduced size of the camera• Reduced price of color cameras• Improved reliability of color cameras• “Starlight” cameras – allow for good video reproduction in low

light situations

Replacing CCTV Camera’s

• Variables to be considered during a site survey– Is the camera to be visible and used as a deterrent to

crime or hidden and used in civil or criminal prosecutions?

– What effect, if any, will the sun have on the operation of the system?

– Where is the best location for a camera?– Should the placement of the camera be high?– What type of lighting is in use?

Old Construction

• Difficulties– exterior fire escapes– old and frequently badly worn locks– common walls– roof access from neighboring buildings– unused and forgotten connecting doors

New Construction

• Modern construction creates offices that are essentially open-top boxes

• Any given floor of a building has a crawl space that runs from exterior wall to exterior wall

The ABC Valve Plant

• Assess the potential risks and provide solutions for the ABC Valve Plant.

• Each proposed change should be supported in terms of why it is needed.

• Include references to the security systems and procedures you referenced in the course.

• Do not attempt to redraw the facility. (Do not cut and paste the diagram into your case study).

ABC Valve Plant• Some students in the past have found this to be a difficult project. • The key is to use the textbook as your guide since it touches on all

the problems listed on the assignment. • Physical security, locks, lighting, card access, alarms, guards, fire,

hiring, visitor control, CCTV, shipping/receiving, etc. • Do not cut and paste the site plan into your case study. • A suggestion is to follow a good/better/best format. The problem

with consultants is that they do not necessarily have a budget to follow.

• Does the cost of the upgrades outweigh the benefit of implementing them??

• Do you get a return on your investment (ROI) in a short period of time (3 years??) Also do not forget to mention controls for raw materials, finished goods, and tools.

The ABC Valve Plant

• Three to five page in length (this does not include title and reference pages)

• The paper should contain a cover page and a list of references in APA format.

• All internal citation of outside sources plus the listing of all references should also adhere to APA format.

• All text pages should be double-spaced and in 12-point font.

The ABC Valve Plant

•What questions do you have?
