Checked my log in the past 5 days it has 4k entries, no Exceptions. Are you using POE for power? I had issue initially with POE, it turned out to be a defective plug. The cam does need up 11W of power with IRs
Speaking of log with 4k entries. Seems like a bug where NVR (192.186.1.40) is constantly re configuring image quality for this one camera where I have motion detection set:
