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 let the

web browser to detect again, manually select the UDP protocol, save, and return HOME

to re-connect.
