Hardware installation

When you switch on, the blue LED on the front lights up and the start procedure begins. During the start
procedure, the blue and red LEDs are both active. This state continues until an IP address is defined. After
you define the IP address, the LED flashes once a second. For troubleshooting hints, see Appendix.

The CMOS network camera first tries to address the wired Ethernet. If it cannot reach this, the camera tries to
reach the wireless network (WLAN). During the search and connection process to the wireless access point,
the red LED on the network camera flashes once a second. The red LED remains in this state until the
connection to an access point is established. During operation in the WLAN or wired mode, the green LED
flashes constantly once a second to show this activity.

Installation in the Ethernet

Make sure that the camera is directly connected to a PC (cross-link cable) or via a switch/hub to the network.
Now connect the network adapter of the camera to the mains network. When the camera is correctly
connected to the network, the blue LED on the front lights constantly. If no network is available, the camera
switches to WLAN mode.

Installation in the WLAN

If the camera is supplied with electricity and no Ethernet is available, the camera switches to WLAN mode
and searches for an access point with the name “default”. This name is known as the SSID (Service Set
Identifier). If an access point with the SSID “default” is found, the LED on the front lights blue.
If connection with the basic settings (SSID: default) is not successful, connect the camera via a cable to the
wired network and configure it.

Make sure that all accessories and articles listed
above are present in the scope of delivery.
Depending on application, an Ethernet cable may
be required. This Ethernet cable must meet the
specifications of UTP Category 5 (CAT 5) and
must not be longer than 100 meters.

To prevent the risk of electric shock, first connect the socket of the transformer to the CMOS-

network camera before inserting the transformer into the mains socket.

Consult your dealer for the correct installation of peripheral devices.

First access to CMOS network camera

Setting the IP address

To set the IP address of the camera:

Use a network cable to connect the CMOS network camera to your computer network.
(The simplest way is to connect the CMOS network camera direct to your PC using a cross-link cable.)

If your PC is not yet integrated into a network, you first have to configure it for the network application. Do
this by opening the Properties page for your network.
(This also applies if the camera is connected to the PC via a hub or switch.)

1. Click

, select and open the Properties page of

the

.

2. Enter a fixed IP address and subnet mask
(e.g.: 192.168.0.95 and as subnet mask 255.255.255.0).

device serial number (no spaces, uppercase letters only). You can change the hostname, the
administrator password and the date/time settings of the camera. If you cannot access the

settings, check the IP addresses of your network adapter and your network camera. The IP
addresses must be in the same subnet area. If necessary, change the IP address of the network

adapter (page 7).

10

10. Now click

to change the IP address of your network camera.

If you use a router in your network, enter this IP address (gateway) in the Default Router field. For a

Cross link connection from the camera to the PC you have to type in an IP address in the
same subnet (e.g. 192.168.0.1).

11. If you disable

Access to the network camera via the Internet Explorer

Defining a password to prevent unauthorised access

When delivered, no administrator password is defined for the CMOS network camera.
The CMOS network camera asks for this number at the start of operation. For security reasons, the
administrator should define a new password immediately. After the new administrator password is stored, the
CMOS network camera asks for the user name and password every time it is accessed. The administrator
can define up to twenty (20) user accounts. Every user has access to the CMOS network camera, but not to
the system configuration. Some system-critical functions are reserved for the administrator, such as system
configuration, user administration and upgrading software programs. The administrator’s user name is
always root and cannot be changed. Following a password change, the browser displays an
authentication window and asks for the new password. After changing the password, you cannot restore

the original administrator password. Your only option is to reset all default factory
settings/parameters.

To enter a password:

Open the Internet Explorer and enter the IP address of the camera (e.g.: <http://192.168.0.99>).

You are prompted for authentication:

Î You are now connected with the CMOS network camera and can see a video stream.

Note: It may happen that your PC’s security settings prevent a video stream. You can change the
security settings to a lower level under “Tools/Internet Options/Security”. Make sure you enable
Active X Control Elements and Downloads.

13

Changing the administrator password

Click “Configuration” and then “Security”.

Under “Root password”, enter the administrator password and confirm it under Confirm password.

Click

.

The new administrator password is saved.

Click “HOME” in the column on the left to exit configuration.

14

Installing the plug-in

When you first access the CMOS network camera under Windows, the web browser may ask for the
installation of a new plug-in for the CMOS network camera. This query depends on the Internet security
settings of your PC. If the highest security level is set, the PC will refuse any installation and any attempt at

execution. This plug-in is used for video display in the browser. To continue, click

. If the web
browser prevents continuation of the installation, open the Internet security settings and reduce the security
level or consult the IT administrator or network administrator.

15

Basic user functions

Main window and camera view

The view of the main page consists of two parts:

Configuration: You can configure the camera with these steps.
Camera view: Camera video stream

Click the configuration link on the left of the picture to open the configuration page.

16

Digital Zoom and Snapshot

Click the magnifying glass under camera view. The control field for digital zooming appears. Disable the
Disable Digital Zoom box and change the zoom factor with the slider.

Click “Snapshot”. The web browser displays a new window containing the snapshot. To save the snapshot,
either left-click it and then click the diskette icon or right-click it and select Save from the context menu.

17

Client Settings

When you first access the Connection Type page under Windows, the web browser asks for the installation of
a new plug-in. This plug-in was registered at certification and can be used to change parameters on the

Client settings page. To install the plug-in, click

. If the web browser prevents continuation of
the installation, open the Internet security settings and reduce the security level or consult the IT administrator
or network administrator.

Two settings are available on the Client-Settings page. Under “Media Options”, you can disable the audio­or video function. Under “Protokoll Options”, you can select a transmission protocol for data transfer
between the client and the server. Two protocol options are available for optimising the application: UDP
and TCP.

The UDP protocol gives you a larger number of realtime audio and video streams. However, some data
packets can be lost due to the large data volume in the network. Pictures can be unclear. The UDP protocol
is recommended if you have no special requirements.

With the TCP protocol, fewer data packets are lost and the video display is more accurate. The disadvantage
of this protocol is that the realtime stream is worse than with the UDP protocol.

18

The selection of the client is normally recommended in the following order: UDP – TCP. When the CMOS
network camera has been successfully connected, the “Protocol Options” box shows the selected protocol.
The selected protocol is registered in your PC and used for the next connection. After changing the network
environment or if you want to search again for the CMOS network camera using the web browser, select the
UDP protocol manually, save it and then return to “HOME” to set up the connection again.

<url> http://<Network Camera>/protocol.html
Network Camera is the original IP address or the hostname of the CMOS network camera.

19

Administrator settings

Configuration / video

Best performance is produced by the maximum frame rate with best video quality and minimum network
bandwidth. The three factors “Max frame rate”, “Constant bit rate” and “Fixed quality” on the video
configuration page are interrelated.

Mobile access to the CMOS network camera

Many modern mobile telephones support access to MPEG4 videostream and GSM-AMR audio data. Due to
restricted bandwidth, only a maximum resolution of 176x144 pixels is supported. You should therefore select
“Configuration for mobile access”, and all necessary parameters are adjusted accordingly.

For high frame rates

To obtain a good visual realtime effect (more than 20 frames/s), the network bandwidth must be sufficiently
large. If the network bandwidth is higher than 1 Mbps, the value for the “Constant bit rate” must be set to
1000Kbps or 1200Kbps and the “Fixed quality” to the highest quality. In the PAL system, the maximum frame
rate is 25, and in the NTSC system, 30 frames per second. If your network bandwidth is more than 384Kbps,
you can fix the bit rate according to your bandwidth and the maximum frame rate to 25 or 30 fps (frames
per second). If the pictures in your environment are changed drastically, you can reduce the maximum frame
rate to 20 frames per second to set the data transmission rate lower. This gives you a better video quality,
and the human eye cannot distinguish between 20, 25 and 30 frames per second. If the network bandwidth
is less than 384 Kbps, adjust the “Constant bit rate” according to the bandwidth and try to get the best
performance by fine-tuning the “Max frame rate”. In a “slow” network, a high frame rate results in unclear,
distorted images. Another way to improve quality is to select “160x120” in the “Size” option, or “320x240”
for a larger view of the pictures. Video quality also depends on the number of users in the network.
Performance can also be affected by a bad connection and by a restriction of the network burst.

20

For higher-quality pictures

For best video quality, set “Fixed quality” to “Detailled” or “Excellent” and the “Max frame rate” so that it
corresponds to the bandwidth of your network. If your network is slow and you get “broken” images, go to
the TCP protocol under Connection Type and select a more suitable transmission mode. Pictures can also be
affected by a time delay due to a slower connection. The more users in the network, the greater this time
delay.

For high frame rates with high-quality pictures

If you have a broadband network, set “Constant bit rate” to or higher and leave “Constant bit rate”
unchanged. You can also set the bandwidth according to the actual network speed or the frame rate. Start
with 30 frames per second and reduce this setting until you get the best performance. However, do not
reduce it to less than 15 frames per second. If the picture quality is not improved, select a lower setting for
“Constant bit rate”.

Protecting the CMOS network camera with a password

Root password

The CMOS network camera is supplied with no password defined. Using this password, all users have access
to the CMOS network camera, including its configuration, as long as they know the IP address. If other users
are to have access to the CMOS network camera, you should therefore assign a password to the camera. To
activate protection, enter a new password. The administrator is identified with this password.

21

Opening accounts for new users

Under “Configuration”, select “Security”. Now go to the “Add user” section.

Add an account with user name and password for a second user. You can define up to twenty accounts for
other users of the CMOS network camera. The camera checks only the access permission of the
corresponding user name and password. This means that two or more users can use the same account at
different levels.

Setting up a surveillance application

The administrator can use the built-in motion sensor for monitoring and signalling changes to the picture.
Snapshots of events can be sent to an e-mail address or to an FTP server. For this purpose, settings have to
be made under the configuration points “Network”, “Motion sensor” and “Application”. For detailed
information, see “System configuration”.

Updating the software version

You can download the latest software from the website. A user-friendly update wizard is provided for
updating the CMOS network camera software (Installation Wizard / Upgrade). Only the administrator can
start the update function. To update the system:

1. Download the firmware file with the name xxx.pkg from the corresponding products folder.

2. Start the update wizard and follow the instructions.

3. The complete procedure finishes in a few minutes, and the system is automatically rebooted.

You can also update the software via the menu item Configuration / management of the CMOS network
camera.

If there is a power failure during the write process of the flash memory, the program in the memory

of the CMOS-network camera may be irreparably damaged. If the security network camera cannot be
correctly restarted following the update, consult your dealer’s technical support.

22

System configuration

Only the administrator has access to system configuration. The following sections explain each element in
the left column. Specific tasks on the Options page are printed bold. The administrator can enter the URL
under the picture to jump direct to the pictures page of the configuration.

Video and audio

General

“Configure for computer viewing” Configure camera for stationary access.

“Configure for mobile viewing” Configure camera for mobile access.

Video

“Video title” The text appears in the black bar above the video window with a timestamp. This timestamp
(date and time) is supplied by the CMOS network camera, and the date and time are supplied by an
integrated realtime clock.
“Color” Selects between colour and monochrome display.
“Frame size” Four options are available for the three video sizes: “160x120”, “176x144”, “320x240” and
“640x480”.
“Power line frequency” Fluorescent light pulses with the mains frequency. Adapt the mains frequency to
eliminate this pulsing in the picture.
Three parameters are available for setting the video quality.
“Max frame rate” Restricts the maximum frame rate, which can be combined with the “Key frame interval” to
optimise bandwidth use and video quality. If the user wants to define bandwidth usage independently of the
video quality, “Constant bit rate” and the desired bandwidth must be selected. Video quality can be affected
due to sending the maximum frame rate within the restricted bandwidth if the pictures are fast-moving. To
ensure video quality (quantising rate) independent of the network, a greater bandwidth is used to be able to
handle maximum frame rate during the transmission of rapidly changing pictures.
“Flip” Rotates the video vertically.

A. Resetting and restoring

At the back side of the netzwork camera is a button. Press this button to reset the system or restore the factory
parameter settings. Sometimes the normal system status can be restored by a reset. If you have further
problems following a reset, restore the factory parameter settings and reinstall and reconfigure the system.

RESET:
Press the reset button with a pointed object.

RESTORE:

1. Press the button continuously with a pointed object.

2. Wait until the self-test runs a second time.

3. Release the reset button as soon as the second self-test starts.

If the factory parameter settings are restored,
all the previous settings are deleted. The system
can be reset or restored.

B. Frequently asked questions (FAQ)

Q. What do I do if I forget my password?
A. Every access to the CMOS network camera requires an authentication. If you are one of the managing
users, ask your administrator for your password. If you are the administrator, there is no way of reactivating
the root password. The only way of accessing the CMOS network camera is to press the reset button on the
rear of the camera to restore the factory-set parameters and then reconfigure the system.

Q. Why does no video appear from the CMOS network camera following authentication?
A. This problem can be caused by various factors:

1. If you have just installed the CMOS network camera and see no video, check the video modulation on the
configuration page.

2. Reduce the security level of the Internet Explorer to enable installation of the plug-ins.

3. If this problem recurs, the users are possibly working at a higher level than is permitted by the system.

Q. What is the plug-in for?
A. The plug-in provided by the CMOS network camera is used for showing video streams in the Internet
Explorer. If your system does not permit the installation of plug-in software, reduce the security level of the
web browser. Consult your network administrator.

Q. Why is there a difference between the timestamp and the system time of the PC/notebook?
A. The timestamp is based on the system time of the CMOS network camera. This is supplied by an internal
realtime clock and can automatically be synchronised with a time server if the CMOS network camera is
connected to the Internet and the function is enabled. Differences of an hour or more are caused by the time
zone setting.

Q. Why is the picture not refreshed regularly?
A. If you use a modem, the bandwidth of the PPP connection is much less that with an Ethernet connection. If
the timestamp difference is unstable, reduce the UART FIFO for reception and transmission under Modem
Properties in the Control Panel. If you use the Ethernet, the reason may be the length of time required to
store snapshots in memory after an event occurs.

Q. How many users can watch the video simultaneously?
A. The number of users is restricted to 20. However, the video quality depends on the network bandwidth.

Q. How fast is the video rate of the CMOS network cameras?
A. The MPEG4 Codec can internally process 30 frames a second. However, the overall quality depends on
various coefficients.

1. Data throughput in the network

2. Shared bandwidth

3. Number of users

4. The visible “complicated” objects result in large image files.

5. The settings on your PC that are responsible for displaying pictures.
The transmission rate of a normal local network can reach over 200 kilobytes per second and approximately
10 to 20 frames per second.

Q. How can I keep access to video streams of the CMOS network camera as secure as possible?
A. The CMOS network camera was developed for surveillance purposes and has many flexible interfaces.
User authentication and special confirmation during installation can prevent unauthorised access to the
CMOS network camera. You can also change the HTTP port to a non-public number. Check the system log
for abnormal activities and their causes.

Q. How fast can the CMOS network camera check the state of the digital inputs?
A. The CMOS network camera checks the input state in less than half a second. However, to avoid the
conditions of a repeated check and ensure a correct functioning of equipment connected to the digital
outputs, the CMOS network camera delays for 3 seconds after each adaptation of the condition. You can
modify this according to your own specific applications. During this period, other conditions are ignored.

38

Q. Why is access to the CMOS network camera not possible while I am setting options in the application?
A. If the CMOS network cameras are started by events, snapshots need more time since they are written to
memory. If the events occur too often, the system is constantly trying to store the pictures. If an event occurs
very frequently, use sequential mode or an external recording program to record the pictures. If you want to
access the pictures via FTP, the parameter can be set lower since FTP responds faster than the web. If the
system is busy with configuration, press the reset button to restore the factory settings and store the system.

Q. The camera was correctly configured, but access to the camera via the http protocol or the RTSP protocol
is denied.
A. Make sure that the corresponding ports (default: Port 80 or 554) in any routers used or the firewall are
released (shared). Test the network protocol “Ping” (Windows command line input: ping <IP address>).

Q. The network camera is connected to the network via a router, but access to the camera is denied.
A. If you want to connect the camera via a router (gateway), you have to define the gateway IP (standard
router). You can only do this if you first connect the camera direct via a cross-link cable and then configure
it.

Q. The network camera is located behind a router with a local IP. How can I access this camera from the
Internet?
A. The router receives a public IP, accessible to anyone, when you dial via the modem (e.g. DSL).
Forwarding – e.g., of an http query from the Internet – is directed first to this public IP. The router must now
be configured so that this query is forwarded to the local IP. Look up the following terms in your router
manual: NAT (Network Address Translation, IP forwarding, IP Server).
