This toy security system simulates a discreet alarm setup for pretend spy play. The set includes two transmitters and a base station with receivers. Pressing a button activates invisible LED light beams between the transmitters, creating an invisible tripwire up to 6 feet apart. If the beam is interrupted, an alarm sounds. The included instruction manual guides setup. For added play value, the light beams can be made visible using fog from a machine or humidifier (not included). This set is part of the Spy Labs Incorporated line, which offers activity kits focused on detective skills like forensic analysis and tracking. Designed for ages 8+, it encourages imaginative role-play and problem-solving as kids take on detective scenarios. Additional spy gear from the line can expand play options.
