For both cameras and video recorders when you want to make a direct connection by opening the ports, the ports to be opened in the router are HTTP, Server and RTSP
If the connection is going to be made by P2P and, due to the security of the network through firewall, etc., the following must be taken into account:
The connections are routed to different domains and their ports:
- dev.hik-connect.com - 8555
- dev.eu.hik-connect.com - 8555
- litedev.hik-connect.com - 8666
- litedev.eu.hik-connect.com - 8666
And the ports used in the cloud are:
Access Service v1.7 Dynamic 31001、31002、31004、31005 TCP access service v2.0 Dynamic 31006、31007、31009 TCP UDP Dynamic 31002、31003 UDP Mobile Dynamic 31008 TCP P2P Dynamic 6000、6001 TCP STUN Dynamic 6002、6003、6004 TCP DNS Dynamic 53 TCP Time Dynamic 123 TCP Alarm Dynamic 7400 TCP Image capture Dynamic 443、80 TCP This is valid for both Hik-Connect and Hik Partner PRO connections
The operation of the tunnels for connecting the applications to the devices through the P2P server is given by whether such a tunnel is created successfully or not:
- If the tunnel is successfully created, the application will get the transmission directly from the device. That is to say, it creates the tunnel and, once it has been made, it "drops" it, leaving the connection made independently of the server. If a test is carried out to see which address has connected to the equipment, the IP of the APP or the device that made the connection will appear
- If the tunnel is not successful, usually due to poor speed, the application will request the transmission from the transmission server and the server will get the transmission from the device, the tunnel will be kept open through the device. When testing the address connected to the device, the hikvision server will be displayed
We cannot control the creation of the tunnels, the network can influence the process
