As of Friday morning a bunch of cameras seemed to have gone offline. They were unavailable in exacq vision NVR but pingable. We had the staff replace the PoE switch thinking if was the root cause to no avail.
Upon further examination, it turned out that most of the problematic cameras are Arecont Vision (single, dual and quad sensors), some of which are online but produce image with pinkish hue or similar distortion. Firmware update seems to fix the problem with pink hue on Arecont cameras, but it doesn't really explain the cause of the outage.
All 60 cameras are on its own LAN, running on multiple dedicated unmanaged PoE switches.
NVR is running latest exacq vision software on public facing Windows Enterprise box, which could have been compromised. Initial logs review doesn't indicate any unusual activity though.
Other than isolating the problem to switch specific segments what else can do done do discern the root cause?
