PTZ Camera quit working

[Juannewbie]

We have a farm setup of 3 cameras. Because of the distance between Barn, Seedplant and Office, we had to use radio transmitters and a receiver. We have 2 cameras by the Barn, 1 normal camera inside and 1 outside which is a PTZ camera. This system connects from a POE injector through the radio transmitter. The PTZ camera is getting power from the POE injector and the inside normal camera has its own power supply and then connects through the LAN connection of the POE injector. Was working fine but the PTZ camera is not picked up by the NVR anymore. Only the inside camera is picked up. They both run through the same transmitter which makes me to believe that the transmitter is working fine. My second issue is by another building which we run a PTZ camera from a POE injector through a transmitter. The POE injector all of a sudden has a flashing LED and when my camera is connected through the CAT5, the power to the transmitter switches off. Could this POE injector be faulty? So to recap. I have two PTZ cameras that is not working which was working for the last 4 months.

1. Could be as simple as corrosion on the RJ-45 male-to-female connection at the PTZ or at the POE injector. I'd inspect those first, if clean try substituting a known "good" cable (solid copper, T-568B or A spec termination on BOTH ends) to see if any change.

If corroded on CAT cable just replace the RJ-45 male but the female will need cleaning with DeoxIT D5. After cleaning and successful testing I would use dielectric grease on all Ethernet connections.

2. It would be good to have on hand a good, spare POE injector that will work with either PTZ to try. But again, I'd check all Ethernet connections for corrosion and cables for physical damage.

FOR BOTH ABOVE:
Look for subtle damage by rodents while you're at it; they love thermoplastic / PVC jackets and conductor insulation.

BTW, are any of the connections directly exposed to the weather?

Thank you Tony. The first thing that I checked was my connections by the cameras. Although they are outside, they look clean and dry. I also gave it silicone when I did the installation 4 months ago. I will inspect the CAT5 for Rodent damage because it is on a farm and I know there is always mice around.

Hi Tony. I put a power supply on the camera where I suspected the POE was faulty and it works now. The LAN connection on that POE works fine and if I only connect the radio transmitter to the POE connection it works which indicates to me that it was overloaded when the PTZ camera was connected to it.

In the other building I replaced the CAT5 cable and is still not getting power to it. The POE does not indicate any problems but I am still going to replace it and check again if it works then. Thank you for your advice.

Oh yes I forgot to mention. You were correct in the fact that corrosion shows up on the connections. Although the camera is not working with the new cable, the 4 month old cable did have a little bit of corrosion on the plugins. It was dry but the pins showed corrosion. I will get dielectric grease and do what you said. Thanks
