The problem with conventional burglar alarms is the fact that they generally don’t stop thieves from doing their job, they’ll just make sure to get in and out of unoccupied buildings as fast as they can before any law enforcement arrives. Which means you still end up the loser, even if your alarm works properly.

The BurglarBlaster Decintegrator (sic) is a fully fitted anti-theft system which will release up to four 6oz cans of OC pepper spray into an area when triggered. The spray is enough to protect up to 4000 sq ft of space, and it syncs with generic alarm systems to give off an audible alert at the same time.

The device, which has a tiny cousin called a BurglarBlaster Tripwire for smaller premises, can then reset itself immediately ready to dispense another shot of spray if there’s another intrusion. The batteries last for up to 4 years, and the whole rig costs $595.00 (with pepper spray can refills at $24.95).
