Garage Alarms - Anyone Use A Xena PIR system?

I’ve just aquired a lockup from a mate for my car & bike which has fairly decent security on it already but I want to fit some sort of alarm incase anyone did manage to get in so had a quick look on google and found this:

Thinking about getting the XENA Ceiling-Mount PIR & Remote system - what do you reckon?

Doesn’t look like a bad idea.

I think the more security you have the better!

12 bore blank mines are the way to go;)
