motion sensor alarm for cabin and back

Hi 184............My wife and I sleep pretty soundly when we are free camping and so I needed an alarm system that 1. covered both the vehicle and the caravan. 2. had to wake us up and NOT scare the living daylights out of us. 3. Needed to, not only alert us but also give the would be thieves a start and hopefully cause them to flee also.

So I designed my own and it has the following.......
1. It is armed and silenced from inside the van.
2. When armed it covers both vehicles, even the stuff on the roof rack as well.
3. Any attempt to disconnect it from the vehicle sets it off.
4. It relys on the van batteries for power.
5. It turns on external flood lights that light all the outside of the van and vehicle as well.
6. It utilises a reversing type alarm that starts soft and steadily increases in volume to where it can be heard even outside the van. ( this gives you a chance to turn off the sound and not scare the crap out of you.) But the flood lights remain on and so allow you to peak out and check your surroundings before going out to investigate.
7. Also you are able to test the system and manually operate the flood lights independantly without setting off the alarm if you hear any strange noises and want to check out what is outside.

It works very well as I have accidently set it off when I have got up and forgot to disarm it.........ask the cook.

184,
Just a thought to consider;
Don't make it too sensitive.
You don't want it going off because you just rolled over in bed, any other in bed activities,or moths flying around.

My Disco has an inbuilt motion sensor as part of its security system, it goes off if a moth flies around in the cab. It's a damn nuisance at 3.00am

Disco.

thanks guys, so cook will know how to create one?
yes, shaking curtains in the wind.

Alarm systems seem to be not so common,
maybe only in modern coaches ... hey, or yachts!

there are wireless systems in US, 600$ up,
better ones not with infrared but alternative technics
to sensor movements
