Dual camera POE with NVR 7616NI-2

I have already run Poe and not able to run another easily (ceilings all finished etc now) and a few years after living at current residence have one location need wider coverage. I see several options now of dual camera (single POE) cameras. They seem to be “side by side” dual 90 degree field of view for a total of 180 or a regular camera on top with a PTZ below. Either of these options would get me a field of view I need without another run, but sounds like my NVR doesn’t support 2 ips on one Poe input.

Any ideas of cameras that would work for this? I could run to a separate POE switch and then run each to individual port but at that point the cost might be worth just upgrading my NVR.

So another question, which NVRs support the dual IP on single POE port and what other features would I gain with a newer NVR?
