This is the telephone that detects motion and silently calls whatever number you desire, allowing you to monitor the sound in the room. Its microphone allows you to listen in on sounds and conversations, enabling you to verify if it's just your cleaning service, a neighbor watering your prized orchids, or a more nefarious plot. Ideal for use in vacation homes or any time you are away, the phone looks like a typical corded telephone and plugs into a standard telephone outlet, requiring no service fees. It has a sensitive motion detector; when you position it to face a doorway or window and someone triggers the detector, the phone will automatically call any number you enter and let you listen. It also functions as a normal telephone. 8" L x 3" W x 3" D. (1 1/2 lbs.)
