Client settings
When you first access the page with the button 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 option and reduce the security level or consult your
administrator.
On the Client setting page, two settings are available,
for disabling audio output, and
for selecting the transmission protocol between the client and server. Three protocols are
provided for optimising the application: UDP, TCP and HTTP.
The UDP protocol gives you more realtime audio and video streams. However, some data packets can be
lost due to the large data volume in the network and pictures can be unclear.
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.
Use the HTTP protocol if the network is protected by a firewall and only the HTTP port (80) is to be
opened. In this mode, no audio is transmitted with the video pictures. The UDP protocol is recommended if you
have no special requirements. The client is selected in this order: UDP / TCP / HTTP. When the security network
camera has been successfully connected, the Protocol Option 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 make a new search using the web browser, select the UDP protocol manually, save it and
then return to
to set up the connection again.
<url>
http://<Video Server>/client.html
<video server> is the domain name or the original IP address of the video server.
If you use a modem for the connection, the video server sends video data only (no audio), since the low
bandwidth does not meet the requirements for video and audio. On the Client settings page, the protocol
option is set to Http protocol.
