Hey all, thank you for your help. As always, you are all very helpful! I got it going. I first disabled the UPnP on my router, then set static IPs for each of the two cameras. Then moved the media coverter LAN cable to the same network switch that the NVR is plugged into. The NVR detected both cams, all I had to do was add them and update the password, and I'm good to go.
