So for a site with several cameras dotted around, a single armoured to each.

If you had an amusement arcade on the site, with 4 cameras, would you run 4 armours to the arcade??

Probably not, it would be too expensive, hard to say without seeing it. I would prefer coax but it maybe easier to use cat5 and video baluns.

Yup i agree, the days of coax are numbered i think, technology is moving so fast its unbelievable, i mean its only a year or two ago that video recorders were the norm, now look, totally unheard of.

1 Cat5 cable with baluns=4 cameras, a lot easier to run than 4 coaxes.

Don't you suffer from picture ghosting, running 4 camera's on a single Cat5 cable..?

I regularly run up to 3 cameras this way with no adverse effect.

Quality just as good with cat5? If you had the choice of coax or cat5 what would you ues??

I have seen cat5 used for the images on entry phones, and the pic quality was ****. Could of just been crapply installed/**** system.

Depends on site circumstances. Cat5 would probably be better for longer runs and\or outdoor and\or multiple runs but for a smaller internal system co-ax.

Hard to tell without seeing the job really. Bit like saying do I use 6942X\4.0 or 6943X\1.0, depends where it's going and what it's doing.

Only if you 'cross' a pair, if you use one twisted pair per signal, no problem.

I ve seen multi core coax, although it was originally used in the early days of computer networking, on a site i used to look after the whole place was covered in them. They look like huge armoured cables with bundles of coax cables in them.

I doubt they're still made or if they are, only to order

Multi core RG179 available through various suppliers, 5 core each individually coloured, no bigger than ct100 very handy for wiring racks etc.

i used to work for bt, and i regularly installed cable with 16 coax's in it, and a 20 pair in the centre!
