In fact, we need to know which network ports are used by network cameras or platforms, which can usually be found in the device setting interface. If you need to access multiple devices from the external network, you need to change the port of each device to realize the function of a public network IP accessing multiple devices.
After logging into the IP Camera interface, click the parameter settings in the upper right corner and select the network parameters in the left menu bar.
Enter the IP address and port, where the data transmission port is the port accessed by the client and the Web port is the port accessed by IE.
At this point, change the WEB service port 80 to 100 or1kloc-0/,102 ... (Normally, port 80 will be used by routers, so you can change it first to avoid conflicts). If there are multiple IP cameras, the ports of each workstation can be increased accordingly. For example, camera 1 use 100.
After changing the port, click OK to restart the device.
