Poe Cable Stoped Working Then 3 Days Latter Worked Again

I have an outside hikvision dome ip camera that stopped working in a 4 camera nvr setup. It worked fine for over a year.

I've tried a bunch of things to narrow downwards the problem. I updated the firmware on the nvr and power cycled it. I switched the nvr port for the camera to verify not a nvr port problem. I used the photographic camera with a brusk cat6 close to the nvr and it worked as expected. The testing leads me to think it is an issue with the cat5e cable.

Information technology seems like poe cables utilize 2 pairs for power and one pair for data leaving 1 spare pair of wires.

What is the best way to test the cat5e cable and determine the issue? I've crimped downward on the connectors again in case there was something wrong, I've added connectedness enhancer to both the connector and the camera and information technology worked for a number of hours before it cut out over again. In one case it cuts out information technology doesn't seem to come dorsum but taking down the camera, pulling the eth cord and putting it back in has allowed the camera to wake up and piece of work for a number of hours.

I am thinking of putting a new connector on the camera terminate as the cat5e cord was a petty bent and compressed under the photographic camera so maybe over fourth dimension the wires within became damaged merely information technology would be nice to know that wire x is the problem that I could use the spare pair and maybe get effectually a damaged wire inside the cat5e cable.

I have a network cable tester it indicates that pair 3/6 are not working. I left the camera plugged in and the dark-green lights cycled through the pairs skipping the 3&vi. I tried it against a good cable and it cycled through all the pairs. Information technology seems similar there are some specialized poe testers on amazon not sure if that would assistance me anymore than this.

Here is a motion picture of a 5e box the installer used. I don't have a picture of the black 5e box just looking at the side of the cable it is marked:

SAE cat5e ansi/tia-568c.2 CMR 75C 4PR E308932 (UL) FT4 Enhanced Verified

I created a cat6 cable and tested with the tester and so cut out pairs 4/5 seven/8. I attached the camera to the nvr with this cable hoping it would merely piece of work since manner A poe only requires 1/2 iii/half dozen and these pairs handle both data and ability. I tested the cablevision with my tester and the ane/ii iii/6 pair low-cal up but using it to connect the camera didn't meet with success.

I had some trouble creating the cablevision and the network tester seemed to indicate that my cable had a bad three/6 ( aforementioned problem as the camera ) then after what felt like hours of trying to create a cable I tried a known practiced cable again and it said bad iii/6 when using the two ports on the tester. I switched to using one port on the tester and i on the remote tester and then three/vi illuminated. Seems similar the iii/vi on the tester is a piddling iffy. I put the remote on the cablevision at the camera end and the tester on the cablevision at the nvr stop and at present all the pairs seem to be lighting up ok.

I permit the network cable sit for the night and checked it and all pairs were reporting good. I took the tester and tried the camera again and this time I was able to see a bad iii/six on the photographic camera. Keeping the photographic camera and cable still I swapped it to the nvr and it wasn't able to be detected so at present I am pretty certain the problem is with the 3/6 pair in the cable that is oem to the dome camera. Looking at some youtube videos of people repairing the hikvision cameras it seems likely that the network cable is stranded. Information technology seems like with stranded cables I should either install a punchdown female person end or solder if I want to repair. For now I've ordered a replacement photographic camera.

I am happy that the problem doesn't seem to be the business firm cable but disappointed that the dome camera would be made so cheaply that the cablevision would break after a couple years - probably designed to neglect.

I retested the poe test since it seemed like the camera cable is damaged I wanted to give it another go when I have the camera/cablevision in a position where the pairs are testing good.

The poe cable test still failed to connect upwards the dome camera so it would seem the camera/nvr combo doesn't work on mode A. I too monitored the power output using the nvr on the camera - when I have a good cable the power output shows the port cartoon power fairly quickly, when I put the style A cable the power doesn't register.

I am pretty frustrated that the network tester I have has a choosy 3/half-dozen light so I ordered a noyafa poe checker and a WiFi-Texas inline tester for poe. I'll play effectually with the camera a piffling bit more once my new tools arrive but I'll likely just install the replacement camera and shelve the damaged one until I get some more fourth dimension to think about repairing it.
