Hi Guys

looking for your advice, please.

I have a Swann CCTV system (DVR 4-4400) connected to 3 Swann bullet cameras and 1 Swann PTZ Camera. The system was working fine, but during recent home renovations, I decided in conjunction with my electrician to upgrade all the cabling to cat 5E (as I'd be swapped out to a POE system at some point in the future). The chap told me that he would install converters and the system would work was as is. All of the cables were upgraded and the electrician's work was done, but the house renovations continued and he said he would be back but has disappeared.

I have purchased the following adaptors:

Everything is wired in, initially one of the cameras worked but in black and white, and the other cameras do not work. I am guessing this is a power-related issue?

There are 4 pairs of cable in each ethernet cable, I am using a pair each for +video, -video, +power and -power. On the PTZ camera I am using a pair for +power, -power and a single cable for +video,-video and the remaining 2 cables for +PTZ and -PTZ.

At present, when everything is connected, I am getting VIDEO FAIL for all 4 channels. Any advice is much appreciated, please.

How are you powering the camera? Are you putting 12v DC on two of the cores of the cat5? If so that is likely you issue. the voltage drop on the 24/26 swg cat 5 cores will be too much. POE runs up to 48V normally not 12v. Also your Swann system uses coaxial cable for video. I don't think you can send raw video down Cat 5 without baluns?
