There are two settings for the client side. One is “Media Option” for users to
determine if audio should be muted. The other is “Protocol Option” which
allows choices on connection protocol between client and server. There are
three protocols choices to optimize your usage - UDP, TCP and HTTP.
The UDP protocol allows for more real-time audio and video streams. However,
some packets may be lost due to network burst traffic and images may be
obscured.
The TCP protocol allows for less packet loss and produces a more accurate
video display. The downside with this protocol is that the real-time effect is
worse than that with the UDP protocol.
The HTTP protocol must be selected if the network is protected by a firewall
and it only allows HTTP Port (80) to be opened. In this mode, audio will not be
sent and only video is operational. If no special need is required, UDP
protocol is recommended. Generally speaking, the client’s choice will be in
the order of UDP → TCP → HTTP. After the Network Camera is connected
successfully, “Protocol Option” will indicate the selected protocol. The
selected protocol will be recorded in the user's PC and will be used for the
next connection. If the network environment is changed, or the user wants to
