Set up a hidden light beam that triggers an alarm when anyone crosses its path! The transmitter spider sends an invisible beam to the receiver spider. When the beam breaks, the alarm sounds. Perfect for aspiring spies and young security experts who love secret missions!

Transmitter spider (smaller lens) sends the invisible light beam. Receiver spider (larger lens) detects the beam and sounds the alarm with a loud beep. Both are cleverly disguised as spiders so your security system stays hidden in plain sight. LED indicator confirms when connection is established.

Use the included reflective mirror with stand to redirect the light beam! Create a challenging light maze that intruders must navigate. The tracking card helps you locate reflected beams. Perfect for complex security challenges, spy missions, and obstacle courses!

Right switch position works best in bright areas (reduces sensitivity). Left switch position works best in dark areas (increases sensitivity). Works in any lighting condition with proper calibration. Learn how real security systems adapt to different environments.
