So when i started this job there was like 6 out of the 21 cameras down. 4 where still under warranty so i RMA them and replaced 2. I’ve been doing other projects here over the last 2-3 months and have had over 8 more cameras suddenly stop working and sent in for repair/replacement. Most seem to go down around the time i put a repaired/replaced camera back up then another camera goes down(maybe withing 24hrs). So im wondering how i should go about finding the issue and fixing it.
* Sometimes logs will show network connectivity issue then will disconnect and not power back on, and other times camera suddenly disconnects and wont power back on. I always bring them inside and check on other switch to make sure before i RMA them. * Most cameras are digital watchdog model:dwc-mb421tir total of 23 cameras. * Cameras are mounted to metal storage buildings, server/Poe switches, etc. are surge protected. * Most direct burial Ethernet cables are ran underground through conduit(but all conduits are filled with water?, and previous installer didn't use what i would consider "quality" direct burial cable.?) Thanks for any suggestions
