Beat the burglar, don't become another statistic!

It is estimated that 9 out of 10 burglars would choose to target a home without a home alarm over those with one.

Burglars today are professional opportunists, they know the exact signs to look out for when choosing a target. The outside bell box is a huge clue, they know the difference between a DIY installation and a intruder alarm installed by a professional security company.
