I have the NVR-ELE8T-P NVR and it works just fine, installed it last week.
This morning I was able to log in, but did not get any camera feed. Recording stopped at 2 am when the system did an auto reboot.
I tried this morning a manual reboot, no change. Unplugged the unit, waited a few seconds, restored power, system works fine now.
How to find out what went wrong?
