The default port of Hikvision 4200 server is 8000.

Generally speaking, devices need to map three ports, namely HTTP port, service port and RTSP port (some older devices don't). When mapping, you need to pay attention to the consistency of internal and external ports. If the internal port is 8000, then the external port should also be filled in 8000.

It should be noted that if users encounter the problem that the port is occupied when configuring the network or server, they may need to replace this port. Before changing the port, it is recommended to know your own network environment and equipment configuration to prevent unnecessary problems.
