The TELESPY? INTRUDER ALERT is an ingenious mix of telephone, microphone and motion sensor. The TELESPY? is an ordinary telephone that actively monitors any room and can dial any number you choose if motion is detected. Upon answering the call, you can hear what is happening in the room through an amplified microphone in the unit. This system allows you to make a determination if there is a crime in progress or if it is just a friend stopping by. After 30 seconds of listening, the TELESPY? resets the connection and arms itself again and begins detecting. Completely portable, no wiring or installation necessary and will work from any phone line. No monitoring fees, no false alarms.
