Wild Planet Spy Gear® Lazer Tripwire

Descripción

In the old days, keeping unwanted nosy brothers and sisters out of one’s room meant hanging a crudely lettered sign that read "KEEP OUT". Today, these matters are a lot more high-tech, as is evidenced by this "lazer" tripwire system. It features three units to be planted at strategic positions around the area one wants to protect. Each unit is capable of emitting a safe LED beam and sense other beams being received, this establishing a perimeter. An included misting water bottle lets you test the otherwise invisible beams to make sure they’re in place and avoiding tripping the alarm. Three AAA batteries are required but not included. --Charlie Williams
