I just started having some problems with 2 5231R-Z dropping connection. I'm on a NVR5216 w/poe switch. The first one started over the weekend, it just went black and the 2nd camera just went out this morning. The other 3 cameras are still working fine. I haven't had time to really dig into it, but now with 2 cams completely gone, I need to figure out what's going on. All I've tried so far is moving the cables to a different port on the switch, flash the NVR5216 to the 9/01 firmware since the release notes mentioned fixing cameras dropping connections intermittently. The NVR registration still shows them as disconnected.
Tonight, i'm going to hook up a laptop to the NVR switch and see if I can ping the cameras and get access to them directly instead of the NVR. Everything was working solid for months until the past few days where two cameras just died.
Anyone have experiences returning/exchanging defective cameras with Andy?
Thanks
