Can i use the 8 cables inside the cat6 cable to get the video from 4 cctv cameras. I find it very bulky to have one big wire for every camera.
i thought if its possible to use 4 pairs to tranfer video via cat6 cable.
Probably, with the right adapters, ones that convert unbalanced coax to/from balanced pairs and do the proper impedance conversion. Quality might suffer a hair, but probably not too much. In theory something like this would work, though I'd prefer "active" devices.
