Chapter 2: Connection and Login The configuration of the device is
carried out with a PC and web browser over the Local Area Network
(LAN).
Alternatively, the PC can be connected directly to the device via
an Ethernet crossover cable (for devices which are powered with
Power-over-Ethernet, a PoE injector is ad- ditionally
required).
2.1 System Requirements To configure the device with live video
display and live audio output, the client PC must meet the fol-
lowing minimum system requirements:
Minimum System Requirements
Windows 7 (each with latest service pack)
Processor (CPU) 3 GHz Intel*) Pentium*) 4 AMD*) Athlon*) 64 3400+
or faster (or equivalent)
Random access memory (RAM) 1 GB (Windows XP) 2 GB (Windows Vista,
Windows 7)
Graphics card DirectX*) 9.0 or 10.0 compatible 64 MB of graphics
memory (128 MB or higher recommended)
Sound Sound card or on-board sound chip (min. 16 bit)
Ethernet 100 Mbps
Software Adobe*) Flash*) Player (latest version) JavaScript*)
enabled Microsoft ActiveX*) enabled Dallmeier Live Video ActiveX
(latest version)
www.dallmeier.com
10
Note that
• a more powerful client PC is required if several devices are
configured with live video display (and/ or live audio output)
simultaneously.
• a DirectX compatible graphics card and the Dallmeier Live Video
ActiveX are not required for the configuration without live video
display or live audio output.
• the latest Dallmeier Live Video ActiveX can be directly
downloaded from the device or from the Dallmeier Partner
Forum.
• the latest Dallmeier Live Video ActiveX can be automatically
downloaded from the Internet after the connection to the device is
established (only with the web browser Microsoft Internet Explorer
and if it is not already installed).
• the configuration without live video display and without live
audio output can theoretically be car- ried out with any operating
system and web browser. However, the configuration always requires
the Adobe Flash Player.
Always install the latest version of the Dallmeier Live Video
ActiveX after the connec- tion to the device is established in
order to obtain the optimal system performance.
Information on downloading the Dallmeier Live Video ActiveX
directly from the de- vice can be found in the section “Downloads”
on page 93.

192.168.2.28
Ensure that the PC/web browser can establish a connection to the
device via Ethernet. Start the web browser. Enter the IP address of
the device into the address bar of the web browser. Confirm the
input.
The connection to the device is established. The graphical user
interface (GUI) of the live mode is displayed:
A HGECB D F
Fig. 2-1: Live mode with adjustable video resolution
A Hide/show title bar B Switch between live and configuration mode
C Live video D Connection method (UDP or TCP)
E Adjust video resolution F Audio On/Off (live audio) G IP address
of the device H Log out of configuration mode
www.dallmeier.com
12
Note the following explanations. Hide the title bar (A) if
required. Change the connection method (D) if required. Adjust the
live video resolution (E) if required. Enable the live audio output
(F) if required.
The “Connection method” does not affect the “Streaming” function of
the device (see section “Streaming” on page 32).
The video resolution setting mentioned above only affects the
display of the live video in the web browser, and is not related to
the encoder settings.
Live audio is only available for logged-in (authenticated) users or
user groups. In addition, the audio encoding must be enabled (see
section “Audio In” on page 64).
Connection Method If the network connection to the device is
established via a router with NAT (Network Address Transla- tion)
enabled, the live video may not be displayed in the web
browser.
In this case, two solutions are available:
The router has to be configured for a correct address translation
of the incoming UDP data packets sent by the device. The User
Datagram Protocol (UDP) is by default used by the streaming
function of the device.
An easier solution is to select “TCP” from the “Connection method”
drop-down list. The device then switches the protocol of the
streaming function to the Transmission Control Protocol
(TCP).
To receive the TCP data packets, the following ports on the client
side must be open:
• Port 30000 for the DaVid Protocol1)
• Port 80 for the Hypertext Transfer Protocol (HTTP)
Note that during data transmissions over TCP
• usually no packet loss (lack of images) occurs. • short-term
peaks in network traffic may occur. • low delays may occur.

drop-down list, select the color for the characters that are
displayed directly in
the video.
The color option “automatic” automatically displays the characters
of the camera name in either black or white depending on the
current image content (image brightness based on pixel values).
This option provides for a better readability of the camera name
and is particularly useful if the surrounding contrast or
brightness levels at the specified position are con- stantly
changing.
Confirm with “OK”.

3.4 User Management The configuration of the device is accessible
for authenticated and authorized users only.
The user management allows you to grant multiple access levels to
the device and to select custom per- mission settings for three
different local user groups. In addition, individual local users
can be assigned to each user group if necessary.
Furthermore, a centralized user and group management based on LDAP
(Lightweight Directory Access Protocol) is supported using an
Active Directory (AD) service such as Microsoft Windows Server*) or
Linux*) Server with Samba.
3.4.1 Information about User Names and Passwords For security
reasons, passwords should consist of at least 8 characters. Do not
use any personal information, conventional expressions (real words)
or names.
A secure password needs to be complex, random and long.
A combination of upper-case letters (e.g. ABC), lower-case letters
(e.g. abc), numerals (e.g. 123) and non-alphanumeric keyboard
symbols (e.g. _ / ^) is usually secure.
Character Sets Supported by the Camera The following character sets
are supported by the camera:
• ISO-8859-1 (all languages except Russian) • Windows-1251 (Russian
language only)
Characters Supported by Dallmeier Recording Systems
NOTICE

3.4.2.3 LDAP Login
This setting allows for an LDAP-based centralized user and group
management using an Active Direc- tory (AD) service such as
Microsoft Windows Server or Linux Server with Samba. The individual
user rights/permissions are granted by three different group
policies defined on the LDAP client (this device).
NOTICE
Login failure In the “LDAP login” mode, a login as a local user
group or a local user is no longer possible.
Incorrect LDAP settings The following LDAP settings may only be
performed by an administrator with ad- vanced skills in LDAP
technology.
In order to be able to set the respective group policies/rights on
the LDAP client (this device), each LDAP user intended to obtain
access to the device must first be assigned to a specific LDAP
group on the LDAP server. Then, the defined LDAP group
(user-group-relation) can be read out by the LDAP client (this
device).
A valid LDAP group name for each directory entry on the LDAP server
must be structured as follows:
[Group prefix][Group suffix]
The group prefix is a user-definable expression (e.g. myhostname),
however, it is required. This allows administrators to assign
different user groups and, thus, variable user rights to multiple
simultaneously installed LDAP clients of the same system design
(e.g. Dallmeier HD cameras described here).
The available group suffixes are fixed expressions:
• Group 1 (administrator): _G4 • Group 2 (user): _G2 • Group 3
(guest): _G1
On the LDAP server, the LDAP group names with the group prefix
myhostname would in this case be as follows:
• Group 1 (administrator): myhostname_G4 • Group 2 (user):
myhostname_G2 • Group 3 (guest): myhostname_G1
However, it is mandatory to also enter the used group prefix (here:
myhostname) on the LDAP client (this device). For further
information regarding this requirement, see the following
descriptions.
www.dallmeier.com
24
Note that the following settings require at least one existing LDAP
user to be a member of Group 1 (administrator).
After the LDAP settings have been made on the LDAP server, the LDAP
client (this device) must be configured accordingly.
In this respect, note the following steps and descriptions:
Ensure that the “LDAP login” mode is selected (see section “Login
Mode” on page 20). Click the “LDAP options” tab.
Fig. 3-10
For the correct access to the directory entries on the LDAP server,
the following information must be entered:
LDAP server: Name or IP address of the LDAP server Example:
ldap://servername ldap://192.168.57.3
LDAP host: Group prefix of LDAP group name Example:
myhostname
LDAP base: Base DN (Distinguished Name, search base on the LDAP
server); object location in the LDAP directory hierarchy Example:
ou=department,dc=example,dc=co,dc=uk
LDAP filter: Default entry: (sAMAccountName=%UNam%)
LDAP attributes: Default entry: memberOf
Enter the relevant data for the access to the LDAP server.
www.dallmeier.com
25
Before you can save the LDAP settings, your entries have to be
verified.
The validation is performed by querying the LDAP directory for an
existing authorized LDAP user with administration rights (member of
Group 1).
The settings on the LDAP client (this device) can only be saved if
the query has been successful (re- turns an internal valid
result).
Click “Test”.
Fig. 3-11
Enter the LDAP user name and associated LDAP user password of an
authorized LDAP user with administration rights (member of Group
1).
Click “Start test”. After a successful test, confirm with “OK” to
save the settings.
From this point in time, a login to this device (now LDAP client)
is possible for authorized LDAP users only.
www.dallmeier.com
26
3.4.3 Rights The three user groups and, thus, the assigned users
can be granted individual rights. In addition, the general public
(user group “anonymous”) can be granted or denied access to certain
types of live images (and/or live audio).
Note that
• the rights of Group 1 (administrator) cannot be restricted. •
certain permission levels cannot be set for all rights. • certain
rights are partially or fully relevant for external applications
only (e.g. for the DaVid Protocol).
Open the “Rights configuration” dialog via “Common settings” >
“User management” > “Rights ...”.
Fig. 3-12
The various user rights are each displayed in a separate row.
The permission level of each user group (column) is represented by
an icon (see below).

Chapter 4: Network
4.1 Basic Settings The network settings of the device can be
configured manually or automatically assigned by a DHCP (Dynamic
Host Configuration Protocol) server.
NOTICE
Network conflicts due to invalid or incorrect IP address In order
to avoid network conflicts, you should clarify if the intended
network set- tings are permitted. In particular, the allocation of
an already used IP address may result in malfunctions.
Open the “Network settings” dialog via “Network” > “Basic
settings ...”.

29
NOTICE
• Contact your network administrator for more information and
assistance. • For troubleshooting purposes, write down the “MAC
address” of the device and
all new settings before changing the configuration.
Note the following explanations.
Connection Type This “Connect type” setting defines the transfer
rate and duplex mode.
The connection type “automatic” (Autonegotiation) is sufficient for
most applications.
Bandwidth Limit Limiting the bandwidth (maximum allowed peak bit
rate) can be useful to prevent video artifacts or frame drops due
to packet loss with low-bandwidth connections.
Domain Name System (DNS) Since IP addresses are rather difficult to
remember, you can also refer to devices by their host names which
allows you to locate the devices or hosts more easily in the LAN
(Local Area Network).
The mapping of host names to their corresponding IP addresses is
handled by the so-called Domain Name Service (DNS server required).
In addition, the IP address mapping can also be stored directly in
the hosts file on your local computer.
The “Host name” (or more accurately, the short host name) specifies
the name of the machine itself (e.g. myhostname).
The “Domain name” is usually the network domain within your LAN
associated with your company and department (e.g. example.com or
intranet.example.com).
Host names are resolved by special DNS servers, also known as name
servers. Resolving host names into IP addresses requires the
assignment of a primary name server (“DNS server 1”, e. g.
ns1.example.com) and, for reasons of reliability and availability,
a secondary name server (“DNS server 2”, e.g.
ns2.example.com).
For example, to refer to the device by its long host name or fully
qualified domain name (FQDN), you can simply use
myhostname.example.com. Depending on the settings of the DNS server
or entries in your local hosts file, you can also refer to the
device by simply using its short host name (here:
myhostname).
“Search domains” (max. 5 allowed, separated by spaces) are useful
if a defined alarm host or UTC time server is not located in your
specified “Domain name”.

4.1.1 Manual Configuration If no DHCP server is available in your
Local Area Network (LAN) or if you want to assign the network
settings manually, proceed as follows:
First, pay attention to the designated and valid IP address ranges
in your network.
Contact your network administrator for more information and
assistance.
Ensure that the “Get IP settings from DHCP” check box is not
selected (unchecked). Enter the “IP address” that you want to
assign to the device. Enter the “Netmask”. Enter the “Gateway”
address. If required, configure the available DNS settings (see
section “Domain Name System (DNS)” on
page 29). If required, clear (uncheck) the “Allow IP-Finder network
configuration”3) check box. Confirm with “OK”.
The connection to the device is then terminated and the new network
settings will be assigned.
After changing the network settings, you have to re-establish a
connection to the device (with the newly assigned IP
address).

4.1.2 DHCP To have a DHCP server assign the network settings
automatically, proceed as follows:
Ensure that an active DHCP server is available in your Local Area
Network (LAN).
Contact your network administrator for more information and
assistance.
Select (check) the “Get IP settings from DHCP” check box.
The IP address, subnet mask and gateway address can then no longer
be set manually but are automati- cally assigned by the central
DHCP server after saving the network settings.
If required, configure the available DNS settings (see section
“Domain Name System (DNS)” on page 29).
To send the “Host name” to the DHCP server, clear (uncheck) the
“Get host name from DHCP” check box and enter a specific host
name.
If required, clear (uncheck) the “Allow IP-Finder network
configuration”4) check box. Confirm with “OK”.
The connection to the device is then terminated and the new network
settings are assigned by the DHCP server (pay attention to the
lease duration).
After changing the network settings, you have to re-establish a
connection to the device (with the newly assigned IP
address):
• The newly assigned IP address can be determined in the “IP
Finder” (PService) or on the DHCP server by searching for the MAC
address of the device.
• The “IP Finder” (PService) must be running on the same LAN where
this device is located.

4.2 Streaming
4.2.1 Video Server The (static) video server provides for a
continuous transmission (streaming) of the generated video data
into the network, even without an application’s active data
request.
NOTICE
Streaming failure due to incorrect configuration settings Note that
the format of the RTP payload that is to be transported must
correspond with the used encoding standard. For information on
encoder settings, see section “Encoder Settings” on page 57.
Open the “Streaming” dialog via “Network” > “Streaming
...”.
Fig. 4-2
Note the following explanations. Select an encoder from the “Input”
drop-down list. Select the transfer protocol, format and method
from the “Mode” drop-down list. Depending on the selected transfer
method, enter the “Multicast IP Address” or the
“Destination IP address”. In the “Port (1024 … 65535)” field, enter
the port number of the service that is required to receive
the IP data packets. Enter the TTL value for IP packets into the
“TTL (0 …255)” field. Select (check) the “RTCP” check box if you
want to generate and send RTCP packets. Confirm with “OK”.
www.dallmeier.com
33
4.2.1.1 Transfer Protocol and Format
Transfer Protocol The transfer protocol defines the communication
rules for the data exchange over the network. The (static) video
server exclusively transports the IP packets using UDP (User
Datagram Protocol).
Note that
• UDP allows for a smooth and fast data transmission with
relatively low delays. • packet loss (lack of images) may occur
with UDP connections.
Transfer Format The transfer format defines the RTP payload that is
to be transported.
NOTICE
Streaming failure due to incorrect configuration settings Note that
the format of the RTP payload that is to be transported must
correspond with the used encoding standard. For information on
encoder settings, see section “Encoder Settings” on page 57.
• RTP/H264 The video data is packetized by the Real-Time Transport
Protocol (RTP) for an H.264 Video El- ementary Stream. Audio data
is not transferred. The data must be encoded using H.264.
The packaging is based on the following standards: RFC3550 - RTP: A
Transport Protocol for Real-Time Applications RFC3551 - RTP Profile
for Audio and Video Conferences with Minimal Control RFC3984 - RTP
Payload Format for H.264 Video
• RTP/MJPEG The video data is packetized by the Real-Time Transport
Protocol (RTP) for an MJPEG Video Stream. Audio data is not
transferred. The data must be encoded using MJPEG.
The packaging is based on the following standards: RFC3550 - RTP: A
Transport Protocol for Real-Time Applications RFC3551 - RTP Profile
for Audio and Video Conferences with Minimal Control RFC2435 - RTP
Payload Format for JPEG-compressed Video
www.dallmeier.com
34
The transfer method defines the data distribution over the
network.
Multicast The data packets are provided with the specified IP
multicast address and port number and then trans- ferred to a group
of receivers (clients) using a point-to-multipoint connection. The
packets have to be transferred only once; the distribution is done
by especially configured routers (capable of IP multicasting). A
client will only receive the data packets if it has (already)
joined the IP multicast group and if the ap- propriate application
service is available at the specified port number. IP multicast
uses the address range between 224.0.0.0 and 239.255.255.255 (Class
D).
Note that certain IP multicast address ranges are reserved for
special purposes. For intranet applications, the use of addresses
ranging from 239.0.0.0 to 239.255.255.255 is recommended.
Contact your network administrator for more information and
assistance.
Unicast The data packets are provided with the specified
destination IP address and port number and then transferred to
exactly one receiver (client) in the network using a point-to-point
connection. The client will only receive the data packets if the
appropriate application service is available at the specified port
number.
4.2.1.3 TTL
The TTL (Time To Live) value defines the lifetime of an IP
packet.
Each router an IP packet passes through reduces the time-to-live
value by one (1). As soon as the value has reached zero (0), the IP
packet is discarded. While preventing IP packets from endlessly
circulating in the network due to routing errors, this method stops
IP packets from breaking through the limits of the LAN (Local Area
Network) and being sent to the WAN (Wide Area Network) (TTL =
1).
Depending on the requirements, a TTL value ranging from 1 – 255 can
be entered. If you enter 0 (zero), the default values are used (TTL
= 1 for multicast, TTL = 64 for unicast).
4.2.1.4 RTCP
The Real-time Transport Control Protocol (RTCP) is an extension to
the Real-time Transport Protocol (RTP) and is used for i.a. the
transmission of periodic status information such as timestamps of
the transmitted video streams.

35
4.2.2 Dynamic Servers A dynamic server is created whenever a UDP or
TCP data transmission is actively requested, for example, by the
Dallmeier Live Video ActiveX, the DaVid Protocol, the Real Time
Streaming Protocol (RTSP) or the SMAVIA Viewing Client.
The “Dynamic servers” tab provides information on currently created
dynamic servers.
Fig. 4-3
The removal of dynamically generated servers is useful whenever
servers, which are no longer used and have not been quit (stopped)
by a request automatically, are to be deleted manually.

4.2.3 Audio Client
This section applies to the following Dallmeier HD cameras that are
equipped with an analog Audio OUT interface:
Box Cameras • DF4510HD • DF4910HD • DF4910HD-DN • DF4920HD-DN
Dome Cameras • DDF4510HDV • DDF4910HDV • DDF4910HDV-DN •
DDF4820HDV-DN • DDF4920HDV-DN
In the “Audio client” tab, the processing of audio data, sent to
the device by external applications using the User Datagram
Protocol (UDP), is configured. The available settings allow you to
activate the output of the received audio data on the analog Audio
OUT interface of the device.
Fig. 4-4
Note the following requirements for the output of audio data on the
analog Audio OUT interface:
• The audio format of the audio source and the audio format defined
in the audio client of the camera (“Mode” drop-down list) must be
compatible.
• The defined destination port in the audio source and the port
registered in the audio client of the camera (input field “Port
(1024 … 65535)”) must be identical.
• With unicast, the audio source must transmit to the IP address of
the camera and the IP address of the audio source (“Source IP
address”) must be registered in the audio client of the
camera.
• With multicast, the IP multicast address used by the audio source
must be identical with the “Multicast IP address” registered in the
audio client of the camera.
For descriptions about the different transfer methods unicast and
multicast, see section “Transfer Method” on page 34.
www.dallmeier.com
37
If UDP is used to transmit the audio data, the settings in the
audio client of the camera must be config- ured manually. If the
DaVid Protocol is used to control the audio output, the necessary
information is sent to the audio client of the camera
automatically.
Note that the settings in the “Audio client” tab are disabled if
the audio output is con- trolled using the DaVid Protocol (e.g.
with SMAVIA Viewing Client).
Controlling the Audio Output with SMAVIA Viewing Client To control
the audio output with SMAVIA Viewing Client, proceed as
follows:
In SMAVIA Viewing Client, right-click the split of the respective
camera. In the context menu, select the required audio format and
bit rate via “Recorder” > “Transmit Audio”.
SMAVIA Viewing Client will then transmit incoming audio data (e.g.
from the microphone input of the PC) over the network to the audio
client of the camera using the DaVid Protocol. The camera decodes
the receiving audio data and outputs the generated analog audio
signals on the analog Audio OUT interface of the camera (e.g. on a
connected speaker).

4.2.4 RTSP The Real Time Streaming Protocol (RTSP) is used to
control the continuous transmission of multime- dia content over IP
based networks (media streams). RTSP uses a direct (bidirectional)
communication with the RTSP streaming server of the camera. On the
one hand to determine the appropriate transmission protocol for the
RTP data transfer (UDP or TCP). On the other hand to transmit
control actions of IP-based RTSP applications (players) such as the
starting and stopping of video transmissions. The encoding,
packaging and transport of the data streams from server to client
is carried out unidirec- tionally using the Real-Time Transport
Protocol (RTP). Usually, RTP transmissions of streaming content are
realized by using UDP (User Datagram Protocol). However, RTSP
transmissions are realized over a TCP connection (TCP =
Transmission Control Proto- col).
The following points need to be considered for RTP transmissions
using UDP:
• UDP is a so-called “unreliable” and connectionless communication
protocol. No connection is established to the receiver/client prior
to the data transmission. The receiver/client does not acknowledge
the receipt of data. During data transmissions over UDP, packet
loss (lack of images) may occur. Lost packets will not be sent
again.
• Usually, UDP packets sent from the Internet to your Local Area
Network (LAN) are blocked by Internet routers/firewalls in
general.
• UDP allows for smooth and fast data transmissions with relatively
low delays, i.e. with low packet delay variation (low
“jitter”).
• Each RTSP/RTP transmission over UDP requires three ports to be
open: A static port for the RTSP control commands (standard port
number: 554) and two dynamic ports for the RTP data stream.
The following points need to be considered for RTP/RTSP
transmissions over TCP:
• TCP is a so-called “reliable” and connection-oriented
communication protocol. A connection to the receiver/client is
established prior to the data transmission. The receiver/client
confirms the receipt of each IP data packet by sending an
acknowledge packet. During data transmissions over TCP, usually, no
packet loss occurs (unless in the case of a buffer overload in the
camera due to a permanent network overload). However, data
transmissions over TCP may be slower than data transmissions over
UDP.
• Usually, only the RTSP port must be open at the Internet router
or the firewall to receive data trans- missions of RTP/RTSP/TCP
packets sent from the Internet to your Local Area Network
(LAN).
• RTSP allows you to embed the transmission of RTP streams into the
existing RTSP/TCP connec- tion; a separate UDP transmission or an
additional port for the RTP data stream is not necessary.
www.dallmeier.com
39
In the “RTSP” tab, you can configure the RTSP server in the
camera.
Fig. 4-5
The standard port number for RTSP is 554.
In the “RTSP server port” field, the port number can be changed
according to your requirements.
To generally prevent access to the RTSP server in the camera, i.e.
not to allow any RTSP transmission, the corresponding check box can
be unchecked.
RTP over RTSP Buffer
Note that the following section only applies to RTP transmissions
over RTSP/TCP.
If the network is busy or if a switch within the network,
respectively the receiver/client, no longer ac- cepts additional
data, the camera can no longer send further image data. The result
is a so-called “data backlog” in the camera.
In order to prevent a loss of images, the yet unsent image data can
– at least for a short time – be saved in an internal RTSP buffer
(default capacity 1024 kBytes). Only in case of a buffer overload
are all saved images lost. Persistent network overload results in a
delay in displaying the images at the client. The delay is propor-
tional to the set size of the buffer (amount of images saved). A
large RTSP buffer is only recommended in case of short-term network
overloads. In case of a persistent network overload, a smaller
buffer as well as lower bit rates are recommended for the
individual encoder settings.

5.1 Video Standard Countries and territories use different
broadcasting television systems.
To ensure a correct video signal transmission, the device must be
set to the appropriate video standard for your country:
• HD 25/50 fps for PAL countries • HD 30/60 fps for NTSC
countries
Open the “Video standard” dialog via “Video” > “Video standard
...”.
Fig. 5-1
Note that the “Video standard” dialog may be locked by external
devices/applications (e.g. by Dallmeier recording systems).
Select the appropriate “Standard” for your country. Confirm with
“OK”.

5.2 Sensor In the sensor settings, the image sensor can be
configured and the image processing algorithms can be adjusted to
the local lighting conditions. In addition, depending on the camera
model, the behavior of the built-in P-Iris lens can be defined and
the integrated IR (infrared) illumination can be configured for an
optimum image exposure in night mode.
Open the “Sensor settings” dialog via “Video” > “Sensor ...”.
Note the following explanations on the various sensor settings. Set
the relevant options. Confirm with “OK”.
You can restore the factory sensor settings at any time by clicking
“Default”.
5.2.1 Global Settings In the “Global” tab, the following settings
can be configured:
Fig. 5-2
42
5.2.1.1 Preset
By using Automatic Exposure Presets (AE Presets), the sensor
configuration can be adjusted very easily to most lighting
conditions in order to always obtain highest image quality. In
addition, AE Presets can be used as useful starting points for the
manual fine adjustment of various camera parameters.
The following AE Presets are available:
Outdoor • Factory default AE Preset • Suitable for most lighting
conditions • Optimized for high-contrast outdoor scenes
Indoor • Optimized for indoor scenes with medium contrast • Obtains
improved detail resolution in the highlights
Low light • Optimized for low-light scenes
5.2.1.2 Color
The following color options are available:
Automatic This setting enables the automatic switching between
black-and-white and color mode as lighting con- ditions change. The
automatic switching depends on the ambient light level:
At low light levels the camera automatically switches to
black-and-white mode and removes the color burst. Without color
information, or rather in black-and-white mode, the image quality
in low-light conditions is much clearer (e.g. less color
noise).
Depending on the ambient light (when a certain brightness level is
reached again), the camera auto- matically switches back to color
mode.
On The video is always displayed in color, even at low light
levels.
Off The video is always displayed in black-and-white.
www.dallmeier.com
43
5.2.1.3 Flip
By using the flip function, the image in the camera can be mirrored
(flipped) horizontally, vertically or on both axes simultaneously.
This provides flexible installation options for desktop, wall or
ceiling applications.
5.2.1.4 Exposure/WB
To always reproduce accurate colors, regardless of the prevailing
light sources and color temperatures (measured in Kelvin), a
correct white balance is required. For this purpose, the camera
provides the following white balance modes:
Auto ATW (Auto Tracking White Balance): The white balance value is
automatically calculated using the color information of the entire
scene and continually adjusted to the changes of color
temperatures. For best results, at least one white object (as
reference white) should be within the scene that is to be captured.
The use of ATW is especially recommended for scenes with constantly
varying lighting situations/color temperatures such as indoor
scenes with artificial light sources and incident daylight.
One Push One Push AWB (Automatic White Balance): The “One Push”
white balance returns a fixed measurement value which is only
recalculated when trig- gered by user request (“Apply” button). The
calculations are based on the assumption that, in correct lighting
conditions, a white or neutral grey object (as reference value)
takes up more than half of the entire scene.
Manual MWB (Manual White Balance): This setting allows you to
manually adjust the red, green and blue gain in the image. The
respective color components can be independently adjusted in 256
steps (0 – 255) with the corre- sponding sliders.
www.dallmeier.com
44
5.2.1.5 Slow Shutter Limit
For a proper exposure, the camera automatically determines the best
combination of shutter speed, aperture (iris opening) and signal
gain. The “Slow Shutter Limit” defines the maximum allowable
automatic exposure time (electronic shutter speed). As soon as the
set shutter limit is reached, the Automatic Exposure (AE) is
exclusively controlled by the automatic iris (aperture) control
and/or the Automatic Gain Control (AGC).
5.2.1.6 Noise Filter
This setting can improve the image quality by reducing noise during
signal processing. In scenes with lots of complex objects, however,
the activation of this function may lead to a loss of detail in the
image.
The noise filter described here can be set at all
resolutions.
5.2.1.7 Lens (CS-Mount Cameras)
This section applies to the following Dallmeier HD cameras that are
equipped with a CS lens mount and a DC auto iris interface:
Box Cameras • DF4510HD • DF4910HD • DF4910HD-DN • DF4920HD-DN
Dome Cameras • DDF4510HDV • DDF4910HDV • DDF4910HDV-DN •
DDF4920HDV-DN
Available settings:
DC control Required setting when using DC auto iris lenses.
Off Required setting when using lenses with manual aperture
control.

45
5.2.1.8 Lens (P-Iris Cameras)
This section applies to the following Dallmeier HD cameras that are
equipped with a P-Iris lens:
Dome Camera • DDF4820HDV-DN
IR Camera • DF4920HD-DN/IR
The P-Iris technology is designed for the precise and automatic
adjustment of the ideal iris opening (“optimum aperture”).
Compared with conventional DC auto iris lenses, P-Iris (Precise
Iris) attains a significantly improved image quality with excellent
contrast, brilliant clarity and increased detail resolution with,
at the same time, a larger depth of field under almost all lighting
conditions.
Especially when monitoring objects in different distances to the
camera, such as in extended hallways, waiting areas or parking
lots, maximizing the depth of field is crucial to the quality of
the results of a later image analysis. In cases of extremely bright
lighting conditions, the P-Iris technology prevents the effect of a
so-called “diffraction blur” (reduction of the overall image
sharpness). This effect would typically occur with conventional
DC-controlled auto iris lenses (especially with high-resolution
megapixel cameras, due to a smaller sensor pixel pitch) when
automatically stopping down too far (high f-stop number).
Available settings:
Auto P-IRIS Together with the P-Iris lens, the camera software,
first of all, automatically determines the most ideal compromise
(also known as “optimum aperture”) between depth of field, lens
resolution and diffraction and, then, continually adjusts the
diaphragm opening (aperture) accordingly with a stepping
motor.
For best focusing results during the camera installation, P-Iris
automatically selects the widest aperture and, with it, the
smallest depth of field. Hence, it is later able to achieve perfect
image sharpness regard- less of the prevailing lighting
conditions.
Manual P-IRIS This option allows you to manually adjust the P-Iris
aperture (see section “Iris” on page 46).

5.2.1.9 Iris
This section applies to the following Dallmeier HD cameras that are
equipped with a P-Iris lens:
Dome Camera • DDF4820HDV-DN
IR Camera • DF4920HD-DN/IR
Fig. 5-3: “Global” sensor settings (P-Iris cameras)
Note that the “Iris” setting is only enabled if the setting “Manual
P-IRIS” is selected from the “Lens” drop-down list (see section
“Lens (P-Iris Cameras)” on page 45).
Available settings:
50 % [Slider on left position] Fixed diaphragm opening (aperture)
for largest possible depth of field.
100 % [Slider on right position] Maximum aperture (diaphragm
opening); useful, for example, under very dark lighting
conditions.

5.2.2 Image Optimization In the “Image optimization” tab, the
following camera parameters can be configured:
Fig. 5-4
Brightness This setting defines the overall image brightness by a
linear adjustment of the tonal values.
Contrast This setting is useful to adjust the difference in
brightness between light and dark areas.
The “Automatic Contrast Control” function allows for the automatic
and continuous contrast adjustment to the prevailing light
conditions.
Sharpness This setting influences the perceived sharpness by edge
enhancement.
Saturation This setting defines the colorfulness and luminance of
colors and therefore their perceived intensity.

48
5.2.3 Day/Night
This section applies to the following Dallmeier HD cameras that are
equipped with a removable IR cut filter and an integrated ambient
light sensor:
Box Cameras • DF4910HD-DN • DF4920HD-DN
IR Cameras • DF4910HD-DN/IR • DF4920HD-DN/IR
The above-mentioned cameras are designed to produce high-quality
images in daylight as well as under low-light conditions or even at
night.
In the “Day/Night” tab, the following settings can be
configured:
Fig. 5-5
5.2.3.1 Mode
Automatic This setting enables the automatic day/night operation
depending on the amount of visible light (de- tected by the
integrated ambient light sensor) and internal defined
parameters.
In low-light conditions, the camera switches to night mode and the
infrared (IR) cut filter is automati- cally removed (ICR ON) which
significantly enhances the sensor’s sensitivity for near infrared
light.
Depending on the amount of visible light (when a certain brightness
level is reached again), the camera switches back to day mode and
the IR cut filter is automatically moved back into place again (ICR
OFF).
The day/night switching threshold levels and the response time can
be manually adjusted (described in the following sections).
www.dallmeier.com
49
Day The day mode is always active. The built-in infrared (IR) cut
filter is always placed in front of the sensor (ICR OFF).
Night The night mode is always active. The built-in infrared (IR)
cut filter is always removed (ICR ON).
5.2.3.2 Threshold Level
This setting allows you to manually adjust the day/night switching
threshold levels (threshold values of brightness and
darkness).
Possible values: 0 – 4 (Default: 2)
Higher Level The camera switches to night mode (ICR ON) earlier but
back to day mode (ICR OFF) later.
Lower Level The camera switches to night mode (ICR ON) later but
back to day mode (ICR OFF) earlier.
5.2.3.3 Response Time
This setting is useful for further fine adjustments of the
automatic day/night switching.
The “Response time” defines the day/night switching delay time once
the particular threshold levels are reached.
Possible values: 1 sec. – 20 min. (Default: 5 sec.)
Example: If during the day the camera is operated inside a room
with a window that faces a public road, the en- tire room could
become very dark for a short time when a big truck passes.
Depending on the set threshold levels for the automatic day/night
switching, the camera would nor- mally switch to night mode
immediately and, moments later, back to day mode. In the reverse
example, there would be a constant unwanted switching from night to
day mode and back as soon as the headlights of passing vehicles
light up the room. Using the “Response time” setting, it is, thus,
possible to delay the automatic day/night switching.

Box Cameras • DF4910HD-DN • DF4920HD-DN
Fig. 5-6
The “Weatherproof housing” setting is useful if the camera is
installed in a weatherproof housing (with a front glass) which may
influence the behavior of the integrated ambient light sensor due
to the light absorption characteristics of the housing front
glass.

51
5.2.3.5 Infrared Intensity
This section applies to the following Dallmeier HD cameras that are
equipped with an integrated IR (infrared) illumination:
IR Cameras • DF4910HD-DN/IR • DF4920HD-DN/IR
Fig. 5-7
This setting allows you to configure the intensity and beam angle
of the integrated IR (infrared) illumi- nation in night mode. The
IR illumination is provided by semi-covert 850 nm high-performance
LEDs.
Note that the “Infrared Intensity“ settings described in the
following can only be made (and are only executed) in the day/night
modes “Automatic” and “Night”.
www.dallmeier.com
52
The following options for the integrated IR illumination can be
selected using the appropriate radio buttons:
Off The IR illumination is always disabled.
Wide This option enables a wide IR radiation cone (non-directional
beam angle) for a large illumination solid angle. This option is
recommended for covering a large area with homogenous (uniform) IR
illumination.
Spot This option enables a narrow IR radiation cone (directional
beam angle) for a small but targeted illumi- nation solid angle.
This option is recommended for covering a small area (e.g. a long,
narrow hallway inside a building) with distant objects while
preventing wall reflections.
Note that white or brightly-colored walls and reflecting objects
increase the perceived IR illumination intensity.
User-defined This option allows you to manually adjust the IR
illumination intensity according to your requirements using the
horizontal sliders “Wide LED power” and “Spot LED power”.
www.dallmeier.com
53
5.3 Exposure Control Using the exposure control, allows you to
adjust the automatic exposure metering of the camera.
Open the “Exposure Control” dialog via “Video” > “Exposure
Control ...”.
Fig. 5-8
Note the following explanations. Set the relevant options. Confirm
with “OK”.
The following exposure metering modes are available:
Automatic The entire image is used for exposure metering. This
setting is only recommended if the entire image area is illuminated
homogeneously.
Center (Center-Weighted Exposure Metering; Default Setting) The
center image area is prioritized over the outer image areas. This
setting is recommended in case the relevant image details are
primarily located in the center of the image area rather than the
outside margins.
www.dallmeier.com
54
Spot Light (Spot Metering) The exposure metering is only determined
in the image area defined by the user. That area is, then, exposed
ideally. However, the other image areas can be heavily over- or
underexposed. This setting is recommended for scenes with extreme
variations in brightness and when a specific im- age area is
required to be exposed absolutely correct.
In order to define an area for spot metering, proceed as
follows:
First, select “Spot Light” from the “Exposure Mode” drop-down list.
Click and hold the left mouse button and draw a rectangle (red)
over the relevant image area that
you want to define for spot metering. Release the mouse
button.
Another click within the image removes the defined metering
area.
Once the area defined for spot metering meets your requirements,
click “OK”.
www.dallmeier.com
55
5.4 Privacy Zones This function allows you to hide (mask) up to 4
user-definable areas in the camera to ensure privacy protection and
compliance with laws and regulations that prohibit certain
locations from being moni- tored and/or recorded. The defined
Privacy Zones are, then, directly blackened in the camera.
Note that the combined area of all active Privacy Zones can
maximally amount to up to 20% of the entire image.
Open the “Privacy Zones” dialog via “Video” > “Privacy Zones
...”.

If the selected image area does not meet your requirements, use the
mouse and click on an un- masked area.
The red masking is removed and a new image area can be
selected.
If the selected image area meets your requirements, activate the
defined zone by selecting the ap- propriate check box.
Click “OK” to apply the settings. If you want to define another
image area as a Privacy Zone, select the appropriate radio button
and
proceed as described above. However, if the combined area of all
already activated zones amounts to more than 20% of the entire
image, you cannot mask any more zones. In that case, reduce the
size of the already defined zones and save the settings again by
clicking “OK”. Then, define the new zone.
Finally, click “OK” to save all settings.
You should always activate and save each defined zone first (“OK”),
before defining another zone. In order to display a previously
masked image area again, deactivate the appropriate check box and
click “OK”. The defined image area remains saved in the camera as
long as you do not click into an unmasked image area within the
corresponding zone. Thus, you can always activate or deactivate the
masking for an already defined image area.

5.5 Encoder Settings
Note that the “Encoder settings” dialog may be locked by external
devices/applications (e.g. by Dallmeier recording systems).
In the “Encoder settings” dialog, the encoding of the video data is
configured. Furthermore, the audio encoding, and depending on the
camera model, the analog video preview out- put can be
configured.
The generated video images can be recorded in “Motion” recording
mode (image com- parison) by Dallmeier recorders of the DMS and VNB
series (as of version 7.1.1). Encoder 1 is used for this purpose
and has to be set to H.264 encoding. Encoder 2 and 3 are, then,
automatically disabled. In addition to recording, a second stream
from Encoder 1 can be used for live display if Encoder 1 is set to
a bit rate not higher than 6 Mbps.
5.5.1 Encoder 1 Open the “Encoder settings” dialog via “Video” >
“Encoder settings ...”.
The “Encoder 1” tab is displayed:
Fig. 5-10
Note the following explanations. Select the encoding standard
(H.264 or MJPEG) from the “Encoder mode” drop-down list. Select the
frame rate from the “Frames/Second” drop-down list. Select the
“Resolution” (width × height in pixels). Select the “Bitrate”.
Select the “Bitrate mode”. Select the “GOP-size” (only with H.264).
If required, select (check) the “Scale Preview” check box to
activate the scaling of the analog video
preview output. If required, activate the “Wide Angle” function by
selecting the appropriate check box. If required, activate the “3D
noise filter” by selecting the appropriate check box. Confirm with
“OK”.

5.5.1.1 Frames/Second
The frame rate (value in fps) defines the number of consecutive
frames generated per second. The higher the frame rate, the
smoother the video playback. However, higher frame rate also
requires higher bandwidth (transmission capacity) and more hard
disk storage space for the recording of video material. 25 (PAL
countries) or 30 fps (NTSC countries) meet the requirements for
real-time applications.
5.5.1.2 Bitrate
The bit rate refers to the number of bits per second used to encode
the video. The more bits are used to represent the video data per
second, the higher the quality is. However, higher bit rate also
requires higher bandwidth (transmission capacity) and more hard
disk storage space for the recording of video material.
Low bit rate = High image compression = Small data volume = Poor
image quality = Low bandwidth and small hard disk storage space
required
High bit rate = Low image compression = Large data volume = High
image quality = High bandwidth and large hard disk storage space
required
Usually, most requirements in surveillance applications are met
with a bit rate between 4 and 6 Mbps.
5.5.1.3 Bitrate Mode
This setting allows you to configure a “constant” bit rate (CBR) or
a “variable” bit rate (VBR) for video encoding.
A variable bit rate dynamically correlates with the changes in the
image. In scenes with many changes in the image, the bit rate is
temporarily increased. The admissible deviations from the defined
bit rate are indicated in percentages. The higher the percentage
value, the higher the maximum admissible peak bit rate and the
longer the regulation time to return to the nominal bit rate.
Example: In case of a defined (nominal) bit rate of 4 Mbps and a
bit rate mode of “variable 100 %”, the peak bit rate may
temporarily increase to up to 8 Mbps.
Variable bit rates allow for a higher image quality and a better
utilization of available hard disk storage space and transmission
capacity. In contrast, a constant bit rate allows for a more
accurate calculation of the storage space required.

59
5.5.1.4 GOP-Size
The H.264 encoding (compression) is carried out by dividing the
video stream into so-called GOPs (Group Of Pictures) of a defined
length (“GOP-size”).
A GOP sequence always starts with an Intra-Frame (I-Frame), which
contains all image data and serves as a reference for the
subsequent images within a GOP. The I-Frame is compressed with a
low compression rate, similar to the JPEG compression method.
Depending on the defined GOP-size, an I-Frame is followed by one or
more Predicted Frames (P-Frames), which only contain the motion
predictions and difference information of the preceding images
(I-Frame or P-Frames) – also called “Long-term prediction”. The
compression rate of P-Frames is much higher than that of I-Frames
since changes in relation to reference images only need to be coded
as motion vectors. Thus, the required bit rate decreases so that,
with a given total encoding bit rate, more bits are available for
the I-Frame. Consequently, the quality (e.g. the detail resolution)
of the I-Frame can be increased by the use of a larger GOP-size.
However, if there are scenes with many motion changes, a high
number of P-Frames can have a nega- tive effect on the image
quality, because the motion predictions become increasingly
inaccurate. Additionally, a larger GOP-size always leads to an
increase in delays regarding processing or accessing a
stream.
A GOP sequence ends before the next I-Frame.
Later on, the individual GOP sequences are used to generate the
visible single frames (reconstruct the original compressed image
data) at the decoder.
The GOP-size “1” (I-Frames only) indicates a low compression level
and should only be used with spe- cific applications, because the
bandwidth requirements increase significantly.
In general, a GOP-size between 6 to 15 provides a good image
quality with a sufficiently high compres- sion level.
Note that reverse playback at high GOP-sizes can lead to frame
drops with some decoders.

5.5.1.5 Scale Preview
This section applies to the following Dallmeier HD cameras that are
equipped with an analog video preview output:
Box Cameras • DF4510HD • DF4910HD • DF4910HD-DN • DF4920HD-DN
Dome Cameras • DDF4510HDV • DDF4910HDV • DDF4910HDV-DN •
DDF4820HDV-DN • DDF4920HDV-DN
The “Scale Preview” function defines the scaling of the analog
video preview output. However, the native resolution of the analog
video preview signal is always 4CIF PAL/NTSC with an aspect ratio
of 4:3.
For an ideal image quality of the analog 4CIF PAL/NTSC video
preview output with an aspect ration of 4:3, you should preferably
select the resolution 4CIF or 4SIF for Encoder 1.
Scale Preview > On [“Scale Preview” check box selected]
This setting is the default setting and is particularly useful for
determining the appropriate focal length and camera orientation
(required image detail) during the camera installation.
• If resolution at Encoder 1 is in 16:9 aspect ratio: Aspect ratio
is converted to 4:3 format by letterboxing (visible black bars at
the top and bottom of the screen). Image is scaled to display the
entire scene. Image is not cropped.
• If resolution at Encoder 1 is in 4:3 aspect ratio but is not
4CIF/4SIF: Image is scaled to display the entire scene. Image is
not cropped.
• If resolution at Encoder 1 = 4CIF/4SIF: Image is not scaled or
cropped.
www.dallmeier.com
61
Scale Preview > Off [“Scale Preview” check box not
selected]
This setting is particularly useful for a precise focusing during
the camera installation.
• If resolution at Encoder 1 ≠ 4CIF/4SIF: Image is cropped. Only
partial section of center sensor area is output. Smaller image
detail causes reduction of angle of view. Smaller image detail
leads to the impression of an increased focal length and an
enlarged sectional view (subject appears closer and larger).
• If resolution at Encoder 1 = 4CIF/4SIF: Image is not scaled or
cropped.
5.5.1.6 Wide Angle
Note that the “Wide Angle” function is only supported at the
resolutions D1 PAL or D1 NTSC and 720p.
Depending on the selected resolution at Encoder 1, a specific area
of the entire sensor is used for image capturing (“On-Chip
Windowing”). As soon as the resolution of the used sensor area
(number of used sensor pixels) changes, the effective angle of view
varies at a given focal length. By default, the resolution of the
used sensor area (input resolution) equals the selected resolution
at Encoder 1 (output resolution). However, by using special
subsampling methods (skipping and/or binning), the “Wide Angle”
function allows reducing the output resolution without decreasing
the effective angle of view. Thus, a considerably larger angle of
view at a given focal length can be used allowing you to capture/
monitor a much larger area of the scene.
Example:
Check box “Wide Angle”: selected (subsampling activated) Resolution
at Encoder 1: 720p (1280 × 720) Used sensor pixels: 2560 × 1440
Read out pixels: 1280 × 720
Check box “Wide Angle”: not selected (subsampling deactivated)
Resolution at Encoder 1: 720p (1280 × 720) Used sensor pixels: 1280
× 720 Read out pixels: 1280 × 720
For further information on the “Wide Angle” function, read the
white paper “Angle of View & Image Resolution” available in the
Dallmeier Partner Forum.
www.dallmeier.com
62
5.5.1.7 3D Noise Filter
The “3D noise filter” function can improve the image quality by
spatial and temporal noise reduction during the encoding process
while increasing the compression performance.
Note that the “3D noise filter” function cannot be activated at
resolutions higher than 720p.
Function characteristics:
• Compares pixels both within a frame and between multiple frames •
Very effective noise reduction • May cause high CPU load and, thus,
may slow down the encoding speed and lead to the loss of
individual frames • May blur moving objects • May cause loss of
detail in the image
