I want to lay mains, Alarm, CCTV and Network (CAT5) from my house to the

The CCTV part, initially was going to be 6 lengths of RG59, however I

heard you can run CCTV over UTP?

There are a few ways to do it:

- Media converters. These may make the exercise more expensive that
the cable.

I have seen these, and also noticed the price (considering I will need 12!)
I was also dubious about any quality loss

- Network cameras

- Standard cameras connected to old PC in garage run as capture server

With the second two, the sources are then effectively run over
Ethernet. Viability depends on what you want and already have,

The need to connect to a multiplexer, so that's out!

Anyone know of a place to buy RG59 cheap!


Can I - would be a lot cheaper on the cable if I can!
If I can, can I run four cameras down one four pair cable?

When I bury this lot in the ground, I presume I will need at least two
pipes - one for the mains, and one for the rest?
Or can I shove it all down one pipe?

Definitely not. The mains should be in any case in SWA cable
buried to 450mm and separate from the pipe containing the other stuff.
I don't believe there is a specific rule on this, but 150mm or more
should be OK.

If the mains was in a pipe, would it need to be SWA?
I thought the pipe would be enough protection
(And the projected run will have a path laid on top anyway, so highly
unlikely anyone will be digging it up!



If I do, as I expect, need two pipes, how far apart should they be in the
ground?
(I don't fancy digging a really wide trench!!)

Thanks!
