I am currently running 12 cameras recording 24x7 on an older Dahua-based NVR (H.264/16ch). The cams are mostly 2MP or 3MP Hik's or onvif compatible cameras. All my cameras and the NVR is on a dedicated 1Gb network, so I don't need any NVR PoEs.
I've been testing a few 4K cameras and now want to upgrade the whole system to 4K, but I have questions about the current NVR specs. The 5216 series looks reasonable, but says it can only support/decode four 8MP channels at once. Is that just for display (output) or does that also limit input? Does an NVR like the 5216 decode all the inbound channels or does it just write them directly to disk in H.265 format? My assumption is it only decodes them if it is doing motion detect or some other AI on the feed. Is that correct? In my case I do not have need for motion detect or any other intelligence -- maybe in the future on one or two cams but that's it. I have physical PIR/MW motion sensors near most of the cameras that go to an automation system.
I'd really appreciate any advice. I have no desire to move over to BI or a windows-based solution -- I can understand the appeal, but my unit needs to be locked in a safe and windows updates are a bag of hurt. I'd like something that can go two years without having to reboot it like my current NVR.
Thanks,
Mike
