In some complicated network environments, you need to set a static IP address or a domain name and ports for HikCentral Professional to enable it to access the SYS server via WAN (Wide Area Network). For example, if the SYS server is in a local area network, and you need to visit the system via the Web Client or Control Client running in WAN, you should enable WAN access and set a static IP address or domain name and ports for HikCentral Professional.

1. Click System > Network > WAN Access.
2. Set the WAN Access switch to ON to enable the WAN access function.
3. Enter a static IP address or domain name of the server for WAN access.
4. Set the following ports, including HTTP, HTTPS, RTSP (Real Time Streaming Port), video file streaming port, and WebSocket port.
