The new (New to me) Caravan is coming tomorrow and I'm starting to think about security
The idea I have is to place a second small 12 volt battery in a cavity and wire up a Hawk car alarm I have knocking about. It has shock and ultrasonic sensors and a siren that could go in the spare wheel compartment
I didn't want to wire it up to the leisure battery as I plan to fit a solar trickle charger to it
Has anyone done the same? I'm fairly sure it will work fine, I didn't fancy one of the cheaper contact/pir alarm units
Regards

Whats the current draw on the alarm? Thats the issue even a very small amount soon adds up when the van is unused and not being charged.
If your adding a solar charger then the leisure battery would be way better than some smaller battery unit.
It will last a lot longer between charges.
I would size it like this...
If the alarm draws 1watt per hour in standby then it will use 24watts a day. I would have at least a 12 watt panel to recharge it. That way it should keep the battery topped up even in quite cloudy weather.
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
