Skip the expensive subscription-based alarm services and go for something a little more… painful. Housed in a high-strength cast aluminum alloy casing, Burglar Blaster mounts to a wall and uses a passive infrared system to detect movement, setting off a nondirectional high-pitched alarm. Should the culprit not deactivate the unit in time using the included key, Burglar Blaster sends them scrambling by releasing four ounces of irritating OC pepper spray. Plus, the system operates for up to 4 years on a single set of C batteries, can be reloaded easily in seconds using (no tools required), needs no clean up after use, and controls areas up to 2,000 square feet. Not quite enough for your needs? Also check out their Decintegrator and Dual Gang Decintegrator ceiling mounted units that fire 4 and 8 cans of pepper spray, respectively.
