Generally, the client’s choice will be in the order of UDP multicast → UDP unicast →

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 detect again, manually select the UDP protocol,

can let the digital output turn into normal state.
