Infrared Trip Wire System Price: $19.99 Store: ThinkGeek
Product Description: You get three Infrared units, one primary and two secondary (each with a sensitivity switch to compensate for different light conditions). Clamp the Infrared units anywhere, and just align each Sender (IR light) to each Receptor (light sensor). Use only two Infrared units, or set up a perimeter with three or more units (multiple sets can be combined for one major invisible protection system). When all the units are connected, a nice voice will announce "System Armed." Break one beam, though, and an alarm will sound, alerting everyone to the security breach.
Please keep in mind, this is a toy. It works really well, but you shouldn't rely on it to protect your gold bars or top secret documents.
