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

What sort of total load on the mains?

no more then 20A - Why does this matter, I didn't ask about cable ratings
here...

What, in terms of alarm? One detector? Two? Just contacts?

a LIM from a Scantronic 9500 (4 wires), with a local PSU for detectors, and
bell box hold off
+ve trigger (1)
+ve for the strobe (1)


How many cameras?
Is the remainder of the system conventional, or is it a first camera?

4 cameras all connecting to an existing multipler in the house (I already
have three cameras connected to this via Co-Ax)

CAT 5.....

What about it?


The CCTV part, initially was going to be 6 lengths of RG59, however I
have
heard you can run CCTV over UTP?

Why six lengths?

4 cameras, one feed back for a monitor, and one spare - why do you ask?

You *can* run video over UTP, subject to criteria being met, such as
ground looping.

I tried connecting a camera directly to a pair in some CAT5e, and the
picture was not good, not awful, but Co-Ax was a lot better.

There are other solutions too, dependant upon your answers above.

Can I - would be a lot cheaper on the cable if I can!

Don't know - depends is the only honest answer anyone can give you on
the info you've given so far.

If I can, can I run four cameras down one four pair cable?

What sort of distance - I don't know your garden, or where your garage
is :-)

The cable from, from the multiplexer would be approbamatly 35 Meters

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?

Not strictly. Which is not the same as saying you can run both mains
and ELV in the same pipe.

You can, however, run armoured cable for your LV.

Or can I shove it all down one pipe?

Only if you want a headache.

If I do, as I expect, need two pipes, how far apart should they be in the
ground?
(I dont fancy digging a really wide trench!!)

Apart works up and down the way too!

Dig a trench deep enough for your armoured - three feet. Lay the
armoured and tape it.

Fill in the trench at least a foot. Run your pipe for the ELV.

Completely backfill the trench.

But more info if you want meaningful answers!
