I'd seen that- are they particularly special relays or just standard ones?
As composite video is only 6MHz bandwidth, I assume it will go through
standard relays no problem- not sure what the 'video' ones improve on.

How long were the cable runs, out of interest?  As I posted a while back,
I'd put together a 25-30m run on cat-5 utp cable, with a couple of phono
plug connections en route, with no obvious problems, but that was for a
mono camera- did you notice any colour problems?
