Wild Planet Spy Gear Lazer Tripwire

short description is not available

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 SKU:ADIB0007PHP88
