I have a offline IP Cam System. I am trying to add extra cams beyond the 16 port POE's (goes up to 32 with router) Need my NVR to see my router and ip cams attached. Not sure how to set up IP's back and forth. (NVR's 16 POE's are full. Added Microtik POE Router to add more cams).

I have PC plugged into and can access router. NVR also plugged into router. NVR has static IP and IPV4/6 are disabled. Not sure what settings to configure with the Microtik hEX S Gigabit Ethernet Router. I only need them to see each other so I can view the additional cams. I don't need any wireless, port forwarding etc. Any help would be appreciated. Thank you!
