Video over Cat5 - CVBS, AHD, TVI, etc? Which is most suitable?

Recommended Posts

Hello, on my home security camera installation I used cat5 when I first set it up, which I later regretted after finding out how superior coax was for video.

I installed baluns and ground loop isolators which fixed some video quality problems, but was still glitchy(tearing, flickering, video anomalies).

Then I tried an AHD camera on the same wiring and haven't had any more glitching(so far).

Is this because AHD is better suited for cat5 twisted pair wiring compared to regular analog video? Are some video standards more compatible with UTP wiring or vice versa?

If I can get away with replacing my regular analog cameras with AHD cameras instead of replacing all my wiring, it would be much easier.
