Newbie looking for a recommended PoE NVR to use with my Mac and I'm struggling to decode some of the manufacturers' sales spiel. I'm viewing output from 4MP and 5MP cams on a 27in 5K iMac which has a greater resolution than the cams and I want to be able to view the cameras' native UHD output rather than a scaled down 1920x1080 image. Trouble is, a couple I've looked at which claim UHD live view and playback don't actually deliver that resolution to a standard PC and would need the cameras to be connected directly to a 4K TV to see the full image - which kinda defeats the purpose of buying an NVR. So which NVRs can deliver UHD to my PC via ethernet? I know the bit about throwing my kit away and getting Blue Iris instead but that's not an option for me.TIA
