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 there are no special requirements, the UDP
protocol is recommended. Generally speaking, the client’s preference should be in the following order: UDP → TCP →
HTTP. After the network camera is connected successfully, the “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 detect again, manually select the UDP protocol, save,
and click HOME to re-connect.
