Create a top-of-the-line, 360-degree security zone in your room! Secrets have never been safer than with this Spy Labs security system. Activate the LED beams in the two transmitters with a push of a button, then align the light beams with the receivers on the base station to create an invisible tripwire. When the barrier is breached or interrupted, the alarm sounds and the interloper is revealed! The transmitters can be placed up to six feet apart and feature a small, discreet design ideal for covert spy play. The included instruction manual walks you through the quick and easy setup process and offers tips and tricks on how to set a successful trap. BONUS: Use the mist from a fog machine or humidifier (not included) to make the light beams visible and stay one step ahead of your super-sleuthing adversaries!
