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.
