Scare Intruders With Realistic Barking Protect your home with a specialized motion detector designed to simultaneously alert you and deter intruders. The Rex Plus Electronic Watchdog is always on duty, guarding and protecting. Rex can sense motion through thick doors, walls or glass. When motion is detected, Rex sounds one of four selectable alerts: an angry, barking watchdog, soothing sounds to alert you of a guest's arrival, alert sounds of both an angry watchdog and a warning siren, or continual tranquil sounds of the rainforest.Senses movement through walls, doors and glassBarking gets more frequent as intruder gets closerPlugs into any standard electrical outletAdjustable volumeBark Sound The closer an intruder gets, the more frequent the barking.
