pinkoos Posted June 17, 2020 Share Posted June 17, 2020 Imagine an L-shaped single story house with the rack at one end of the L and the dead camera feed at the other end of the L - that's the problem I'm dealing with The particular camera feed has been dead for several months - nothing shows up in C4 and no feed shows up when accessing the camera directly through it's address in a web browser I finally got around to pulling it off the exterior wall this weekend and plugging it directly into the POE switch in the rack - as soon as I did that, the camera turned on and I was able to get a live feed in the web browser So, it seems the camera is fine, but something is wrong with the wiring somewhere between the POE switch, through the attic and all the way out to the ethernet termination outside the house The other cameras plugged into the POE switch have been working fine and I did try plugging this particular camera's CAT5 into different ports within the switch several months ago as part of my initial troubleshooting, but no luck My question - how do I trouble shoot this?

lippavisual Posted June 17, 2020 Share Posted June 17, 2020 Need to certify the line from point a to b. Cheap testers just test continuity and wire map. Testers like Fluke, etc. can tell you exactly where a break is in the line and such. There are places that rent these certifying testers or you can call your local Voice/Data company. Not all AV companies have these testers. Quote Link to comment Share on other sites More sharing options...

Not all AV companies have these testers.This but a cheap tester may indicate that replacing one or both terminations would be a good start. If the cable between those points has been stable and undisturbed that would be my expectations. Likely the outdoor / more exposed termination has gone bad.

pinkoos Posted June 17, 2020 Author Share Posted June 17, 2020 Interesting, how cheap are these 'cheap' testers? Something I can just buy off Amazon and start working on myself, as it would probably take some time and expense for my dealer to make it out Quote Link to comment Share on other sites More sharing options...
Pounce Posted June 17, 2020 Share Posted June 17, 2020 Google, buddy. https://www.amazon.com/ELEGIANT-Multifunction-Collation-Telephone-Continuity/dp/B01HCQSHNG Plug it into both ends. Turn it on. Lights tell you if its connected correctly. Quote Link to comment Share on other sites More sharing options...
eggzlot Posted June 17, 2020 Share Posted June 17, 2020 Could be bad termination. Could be a mouse ate the wire In the wall. Could be a kink in the wire. If it works when removed and plugged into switch it’s definitely the wire. The expensive tester can locate more but if you don’t know how to run a wire then it doesn’t matter. If you can’t reterminate it doesn’t matter either. Something is up with the cable or crimps. Quote Link to comment Share on other sites More sharing options...

If the OP doesn't have the gear to put a new plug on the cable they are probably better off calling the installer. Quote Link to comment Share on other sites More sharing options...

You know that. Can you crimp a new end? If so buy that equipment and reterminate. If that doesn’t work something along the cable is bad. You’ll likely need someone to go fish around anyways. And they are likely to have the expensive tools to locate what/where is the issue Pounce 1 Quote Link to comment Share on other sites More sharing options...
pinkoos Posted July 3, 2020 Author Share Posted July 3, 2020 So I ordered the item that was linked above and did some testing last weekend. 1: does anybody know why two wires were pulled out of the CAT5 and plugged into the camera separately as shown in the picture? 2: test on 'network' setting outside the house - '2' was a bit dim and 3/4 didn't light up at all...I guess those are the two wires pulled out and plugged into the camera separately? Why would '2' be dim? 3: same 'network' setting test inside the rack - all 8 lights are lighting up, full intensity - nothing dim / nothing off 4: when the device in the rack was set to 'Scan', the device outside the house showed all lights fully bright except 3 and 4 - again I'm guessing 3/4 are off b/c those wires are pulled out from the main ethernet cable? Is there anything that can be deduced from this info? Thanks Quote Link to comment Share on other sites More sharing options...

pinkoos Posted July 3, 2020 Author Share Posted July 3, 2020 I believe these are POE cameras (Lilin) but those two wires were pulled out from the 8 wires in the CAT5 cable Quote Link to comment Share on other sites More sharing options...
lippavisual Posted July 3, 2020 Share Posted July 3, 2020 Is it an analog camera? if not, looks like you’re not using a Poe injector for it because they spliced out 2 pairs for 12vdc power. Quote Link to comment Share on other sites More sharing options...

It's IP and it's plugged into a POE switch back in the rack Quote Link to comment Share on other sites More sharing options...
Pounce Posted July 3, 2020 Share Posted July 3, 2020 Just to be clear you disconnected both ends of the cable for that camera for the test correct? You unplugged it from the camera and you unplugged the other end of that cable in your rack so it wasn't connect to a switch . You then took the tester and plugged one end of the cable into one part of the tester. You then went to the other end of the cable and put the other end on the cable. You then checked the lights on the tester. All this correct? Quote Link to comment Share on other sites More sharing options...
ejn1 Posted July 3, 2020 Share Posted July 3, 2020 With 2 wires pulled out, how do you know your POE switch is powering the camera? is the power voltage light up on your switch on that port? and 2 confirm, 6 wires are in the ethernet plug?
