Lectrician Posted May 18, 2005 Author Share Posted May 18, 2005 I think you will find the coax is protected, I too would run a data cable, but my origional response was to clarify that what the CCTV guy had told him was correct. 53738[/snapback] Im not invloved in the spec at all - I was just concerned for the customer, as this guy is puting in cables only - no job in the pipeline for cameras yet, it was just because the ground was open. He has used green coax which looks like 'hi-tuff' cable. I was surprised it wasn't armoured - I actually assumed it was until I looked at the end.

Havent seen that for a few years, sort of like armoured without the armour, but a bit stiffer! A bit like that stuff BT use with the horrible vaseline filling? Def. should be ducted or conduited over then, in my book, although you'd probably get away with it. I guess they are thinking they will be able to get power locally if thats all there is. Stu. So, I've decided to take my work back underground.... to stop it falling into the wrong hands Link to comment Share on other sites More sharing options...

Monteey Posted May 20, 2005 Share Posted May 20, 2005 Yup its direct burial cable, we use it quite a lot, its good stuff although a pain in the backside to strip and terminate.

Don't do CCTV that much (only bog standard). If you have a couple cameras, can you multiplex them down a single coax??

Monteey Posted May 20, 2005 Share Posted May 20, 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 Mark Hawks Ex BT Openreach Field Service Now Self employed telecom and data engineer www.mphtelecom.co.uk Also back doing sub contract work in the security industry.

If you had an amusement arcade on the site, with 4 cameras, would you run 4 armours to the arcade?? Email : martin@askthetrades.co.uk Link to comment Share on other sites More sharing options...
