Sure, you could just install a burglar alarm in your home, but no robber is going to be afraid of some incessant beeping. He’s going to grab what he wants and bolt out of there before the cops ever show up.
If you want to stop a would-be burglar dead in his tracks (and make him cry like a six year-old girl), you might want to install a Burglar Blaster. The Burglar Blaster is a highly durable, cast aluminum alloy case with a built-in passive infrared detection system. After a certain amount of time, the Blaster will fill the area with pepper spray, incapacitating the intruder and preventing him from making off with your belongings.
The device can be painted to blend in with any surrounding and runs for up to four years on a set of “C” batteries.
