My 2 cent's.

A Burglar Alarm is a great deterrent. Just seeing that box sitting on the front of your house will put them off when there are other houses around that don't have one.

Wireless systems are dead easy to install too and run for about 2 to 3 years before needing any battery attention.

When I was living in the City our home was broken into as well as a few others on the same night. Not one of the houses that had an alarm were touched.

It's the worst feeling ever, so get an alarm ASAP.
