The Electronic Watch Dog is a unique alarm system that uses the same advanced technology as some police radar systems. With microwave technology, it is able to "see" through walls to determine when someone is approaching and how close they are. When an intruder comes within 20 feet, it begins barking like an angry German Shepherd. The closer they come, the more frequent and more threatening the barking becomes.
