No Signal

[mrjgp]

Good afternoon, 2 of my turret cameras are currently off signal after running for a year. One actually came back on for an hour then went back off. I see the IR lights on at night so they're getting power. I tried to log into the cameras but its not connecting. I read a few other posts on this topic but I'm just not sure what steps to check. Please advise.

Ones I can think of off top of head:

1) corroded Jack, check CAT cable on cam
2) POE switch failing, remove all but one failing cam and see if comes back, try different port on switch, etc.
3) Failing CAT cabling, did you use solid copper CAT, did you terminate with your own jack that may be failing?
4) If possible, take one down and bench test it with a different CAT cable or run a temporary cable to cam and test it out
