More and more router video surveillance users are using port mapping to allow external network users to directly access internal network surveillance video, meeting monitoring needs.
However, sometimes non-standard configurations by internet cafe network administrators can cause the router video surveillance mapping function to fail.
In addition, you should also pay attention to the following aspects:
1. Check Server Port Settings
Video surveillance generally requires the use of multiple ports, including HTTP ports and monitoring ports. Both ports need to have mapping configured on the router.
The internet cafe router section editor reminds you that after modifying the server’s monitoring port and data port, you need to restart the server for the changes to take effect.
2. IP-MAC Binding
Check if there are any issues with the "IP-MAC Binding" in network security settings. If the bound address does not correspond to the server’s actual address, the server’s data will not pass through the router, causing the router video surveillance mapping to fail.
3. Port Reuse Issues
In environments with multiple surveillance servers on the internal network, the internal ports are usually the same by default. In this case, it is recommended to set the external ports to different ports to ensure normal access from the external network.
