Home > Connections Screen
The following options are available from the Connections settings screen:
Media Option:
Option for users to disable or enable audio when viewing video.
Protocol Option
The UDP Protocol should be chosen for the most users. Generally the client
computer will automatically try these protocols in the following order, UDP ->
TCP -> HTTP.
After the client connects to the DCS-2000 successfully, the working protocol
will be displayed in "Protocol Option". The chosen protocol will be recorded
in the user's PC and used for the next connection. If the network environment
is changed or users want to let the web browser automatically detect the
protocol, select UDP manually and click Save to change the setting and
return Home to reconnect with the new setting.
Options:
UDP Protocol - Quality real-time performance compared to TCP. Some
packet loss due to network burst traffic and images may be obscure.
TCP Protocol - Packet loss is less likely to occur and video displays are
more accurate.
HTTP Protocol - If the network is protected by a firewall and it opens HTTP
port (80) only, HTTP protocol must be selected. In this mode, audio is
disabled and only video can be viewed.
