I thought about external pirs or parallel beams, but there is quite a lot of cats in my street, so would probs activate all the time.
I have an alarm at present, risco cpx, when it activates it's bells plus vo com to my mobile.
I would be hoping that when it was ripped off the wall the alarm would have activated, and they would have left empty handed, it's a 1.1m solid dish with a motor, lnb arm and bracket which weighs a tonne, which isn't the easiest of things to transport about.
I had a camera pointing at my van, but that didn't stop some cnut breaking the window and stealing my test monitor.
I thought about a single core of 6 core in a loop from the panel out and around the bracket of the dish and then back, but don't really fancy having to replace every couple of weeks.
