When I first moved into the place im at now, our garages were getting broken into on a regular basis. The only thing i was worried bout was them scratching my kid parked down there, so now, $90 later, if the door is even remotely jarred open it trips a silent alarm, waking or alerting me upstairs so I can stroll down and dish out some real street justice.
Happened once, found a guy snooping downstairs, flashed my wallet badge and asked him for ID, stoopid prick gave me everything I needed to know about him too! Dont know whether it was the badge or an accompnaying piece of equipment, but we have had no problems ever since!!!!!!!
