Ok, I went to 192.168.1.108, did the initial setup, set the password to the same as the NVR, the IP to 10.1.1.67, and the gateway to 10.1.1.1 then logged out. When plugged into the NVR, the camera connected (yay!!) and displayed the live image.
I then entered my NVR's IP into the browser, and looked at the camera list. Channel 3 is now there, with the IP 10.1.1.67, but instead or "Port3" it shows as "37777". And when I hit the IE icon, of course it won't open, just times out.
I changed to the NVR interface, and had a look at the under Settings > Camera > 'PoE. Channel 3 is showing as status red circle (disconnected) and Rate as " - " even though the camera image is displaying.
I've wasted a good couple of hours on this now, and I'll be damned if I know what's going on.
*edit:
In brief: when plugging a factory reset camera into a PoE NVR, it won't connect and doesn't show up at all under camera registration.
Faulty camera? Faulty NVR? Or am I missing something?
