Hello, Tianyi Butler, what is the reason for the camera port conflict? The reason for the port conflict of Tianyi watchdog camera is IP address conflict. Because two cameras of the same switch conflict, that is, the IP addresses of the cameras on the monitoring software conflict, the problem of camera conflict is caused. After the cameras are installed, they are connected to the hard disk video recorder through the signal line, and the hard disk video recorder is connected to the computer host to download the monitoring software. Each camera has an IP address, so it can be used. If IP addresses are duplicated, conflicts will occur.
