Hi all,

I am setting up a CCTV system, which will have about 8 cameras.
Each of these cameras requires a 12V 200mA supply.

After a bit of research, it appears I can have one transformer (say
12V 2A), and take LV power lines off for the cameras in parrallel.
Does this seem right?

Ok, my problem appears to be finding a transformer!
Firstly, they seem to have different power ratings. Some are in amps,
some are in Watts, and some are in "VA"s whatever they are. Anyone
know how to work out one from the other.

In my CCTV System I am using alarm auxiliary power supplies.
The usually come in a white metal case with a hinged door
They also have the added benefit of having provision for a 12v battery, in
case of a power failure!

Obtainable from anywhere that sells alarm systems (Not DIY ones though!)

....They don't usually come with a battery!

If you just want a non battery backed supply, then www.cpc.co.uk part number
SR0407066 should do you!
