ian.cant Posted May 20, 2005 Share Posted May 20, 2005 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?? 53943[/snapback] 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. Link to comment Share on other sites More sharing options...
Monteey Posted May 20, 2005 Share Posted May 20, 2005 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.

breff Posted May 21, 2005 Share Posted May 21, 2005 1 Cat5 cable with baluns=4 cameras, a lot easier to run than 4 coaxes. The opinions I express are mine and are usually correct! (Except when I'm wrong)(which I'm not) Link to comment Share on other sites More sharing options...

Lectrician Posted May 21, 2005 Author Share Posted May 21, 2005 I regularly run up to 3 cameras this way with no adverse effect.Jef 54008[/snapback] 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.

Guest Posted May 21, 2005 Share Posted May 21, 2005 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. Link to comment Share on other sites More sharing options...

Rik Posted May 21, 2005 Share Posted May 21, 2005 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 53941[/snapback] Multi core RG179 available through various suppliers, 5 core each individually coloured, no bigger than ct100 very handy for wiring racks etc. Link to comment Share on other sites More sharing options...
