Picture is very poor, zooming in on dvr picture becomes useless. I will certainly be changing this to be using 1 pair only. Thanks for your response.

Hi, I'm new to CCTV and have a question regarding wiring up cat5e cable to analog cameras. We have a 4 x analog camera setup connected to DVR using Cat5e and baluns. The cat5e cables supply power to the cameras (not locally powered). They are currently wired using 2 pair to carry video and 2 pair for power. I have read that they should be wired using 1 pair to carry the video and the other 3 pairs use for power. Could you say if this is correct and why and what problems we could expect giving our current wiring setup? Thanks for your help and assistance.
