I also have the same rnl8-410 - if I plug in a poe camera to it, it doesn't show up. onvif or otherwise.
The nvr only seems to find cameras plugged into my router.
This nvr appears to have it's own private subnet class b 172.16.25.x
if this is the case, why don't cameras get that ip when plugged in?
