A home alarm system will automatically call the police in the event of a break-in, but by the time officers arrive, the intruders may have already taken your valuables. So this laser security system serves as an additional visual deterrent that your home is as protected as the most secure government facility.
The $220 unit creates a set of sweeping red laser walls that appear as if they’re constantly scanning back and forth in a room, looking for intruders. However, in reality, the system’s not actually able to detect anything. It’s all just a ruse intended to make a would-be intruder think twice about breaking into your home. But unless the perps are willing to make a Mission Impossible-like entrance, they’ll probably just move onto your neighbor’s house instead. [Spy Gadgets via The Red Ferret Journal]
