Alarm cable is usually 6 core and not twisted pair, so would probably
be worse than cat5?

As an alternative approach, you can achieve perfectly good Composite
Video
quality transmission - with stereo sound - using wireless video senders
such ashttp://www.maplin.co.uk/Module.aspx?ModuleNo=217641

If you don't mind getting interference from microwave ovens or wireless
network routers

I tried using one of those (a Tesco own-branded one) to send signals
from my PVR to the kitchen TV - then I switched the microwave on and
nearly jumped out of my skin when an extremely loud buzz was emitted
from the TV speaker, and the picture went haywire.

Just how much energy actually does "leak out" from a typical microwave
oven?

A fair bit I reckon. When Hil is microwaving (a new verb for you there!) in
the motorhome I can't use my bluetooth earhole device. I have to leave the
van and walk up the road. When it is raining and I'm sitting all comfy in
the front talking on the phone I have been known to shout "Oi! Turn that
****ing thing off!" to which my beloved will reply, "No ****ing tea for you
then, you miserable old ****er!"

Enough for a passive (moving coil meter with diode) detector to register a
signal when held against the door seals.

That's a worse case of course because the bluetooth is using the same
frequency band as the oven's 600w of RF output.

The video signal in the cable will be interfered with by the switching
PSU with its nasty harmonic outputs radiated from its case and back
down the mains supply cable.

Her indoors has one of they Bilk reciva things that uses 2.4 Ghz wi-fi
for radio from abroad and it sits on top of the microwave and no
interference at all:))

Some are much better then others .. generally newer ones are better in
this respect...

If thats doing that I'd have it looked at. We know one that caused some
radishes to go soggy in three days when left in a bowl nearby .. and yes
we repeated the experiment which ended with it going to the menders
where it was pronounced as very leaky indeed and thence it went to the
tip...

Another one took out an industrial grade Western Multiplex 2.4 Ghz link
when the dish within 100 metres and solid metal and facing the other
direction was badly affected!.

Once again replacement saw that problem off..

Cat 5 used with balun units will go for quite some way ....

You wouldn't use it with alarm cable;!...

Yes I would have thought so. They use four core for this if they have any
handy. -12V and video ground, +12V, video, spare or audio. The result looks
OK, sort of, but when you change it for coax it tends to be an improvement!

Well, it was 30 years ago. I built the leakage detector as a project in one of
the electronics mags. ISTR it was calibrated such that FSD was the legal
emissions safety limit, my meter registered about 20% FSD when held against
one part of the door. (Can't remember what the exact figures were).

I'm not too worried, I'm still alive, and so are my parents, the microwave
oven (a Belling) went on working until 1992, nothing they have had since has
lasted that long, worked as well, nor been as easy to use.
