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).

8. Select one of the camera models found.
9. Click to enter camera setup mode. If you have to enter a password, use the
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 , you do not have to reassign the IP address of this
camera following a power failure. Otherwise, you have to reassign the IP address after every camera
restart.

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:
ÎYou 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 audio-
or 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.

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.
