Wireless Wander Alarm

Place the Wireless Wander Alarm near the doorway and when someone wanders within 15ft of the detector, the alarm sounds, alerting you of an unwanted wanderer or trespasser. The transmitter makes no noise, eliminating the risk of agitation. You can select one of three alarm tones: musical, bell, or siren and the alarm will continue to sound for 2 seconds, 30 seconds, or 1 minute after last motion is detected. The detector and transmitter use one 9V battery each which are sold separately. The receiver is AC powered (power supply included) or three AA batteries (sold separately) can be used.
