I'm still having issues with this cam refusing to stay operational. It will record sporadically, less than a half hour and then black out for a long while. I've been way busy with higher-priority things and have made no real attempt to resolve this. I bought one of the cable tester kits as linked by others here and the cable passes the test for continuity, no faults indicated. This camera, when previously used both on the bench and mounted in another location, worked fine before. I need to test the PoE delivery at the birdhouse as well. I was previously chasing issues with multiple cams which turned out to be a dying PoE switch, since resolved. But for some undetermined reason, this cam is being difficult. For multiple reasons of priority, I haven't explored the issue, yet. I need to swap cams, first, as a most basic test, and follow on from there.
