I previously had 4 Hik cameras running fine connected to POE switch then to router. Also had Hik NVR connected to same LAN and it detected cameras. I decided I wanted to use the built-in POE ports on the NVR so moved cables over from switch, turned on POE power to these channels, and now I'm getting the error "the network is unreachable" error. The NVR is not detecting any of the cameras. The NVR camera menu is showing the original IP addresses of the cameras. Should the NVR be assigning new IP addresses since the cameras are being directed to it, and not the network? I know there is a simple answer for this.
