Infrared Wireless Home-Alert System
This infrared alert system uses a sensor and receiver combo to alert homeowners when something is afoot on their property. Position the sensor above a garage, near doors, or in backyards. When it detects motion, the receiver makes a chiming sound. The sensor can also be used like a doorbell, placed inside mailboxes to signal the postman's arrival, or used to prove to everyone that the coatrack is actually sentient and follows you at night.
