Picked up one of these yesterday, more to play about with. Makes an uncomfortable noise in an enclosed space like a camper. Painted black and even integrated into the dash? Put it this way you soon want to get out if it goes off....

Under a fiver, two remotes, and board will run off 6v. Doesn't need to be in the case it came in. Just needs a voltage dropper to obviate need for AA batts. One for Ghost methinks.

It would work off 5v just use a 12v-5v voltage regulator.

Or if you want to power your dashcam and sat nav use a 5A one and fit some dc sockets.

You know me too well Ralph, :D 8)

I have had one of these in the Hi-Top since I bought it ;) (I used to sell them in my Electronics Shop as "Shed & Caravan" Alarms).

I have not bothered with a power supply, when I fitted it (in a concealed-ish place), I hard wired 4 x "C" Ni-Cads (in a battery box thing) to it. I have only had to re-charge them once in 2+ years.

For some unknown reason, despite the fact I had not "armed it" the bliddy thing went off once in the night. It was an unpleasant 30 seconds until I found the key fob thingy :twisted: :twisted:

I will leave mine in the Hi-Top when we sell it (soon) and not sure if I will fit the remaining one I have into the Tin-Top as it is all a bit "belt and braces" as I (and no doubt many others) have a conventional alarm fitted to the Tin-Top as well.

Any idea of a way to make it a tadge louder still John? I think its a peizo element in there but presumably it could be hooked up to something bad ass? Relay? better speaker? attach to a 300 watt amp?? :D

Yeah, just enough to unsettle their eardrums as they rifle through your glovebox Rob :rofl

Seriously though, if the sound is loud enough, they're going to leg it pretty fast. Alarms are one thing but an ear-splitting racket inside a metal box has to be good way to get them out smartish.

Well, unless they're stone deaf or go prepared.....

Actually, aren't those dutch caps?
