The Electronic Watchdog uses the same advanced technology as some police radar systems. Because they use microwave technology, these barking dog alarms are able to "see" through walls to determine when someone is approaching and how close they are. When an intruder comes within 20 feet, they will begin to bark like an angry German Shepherd. The closer they come, the more frequent and more threatening the barking becomes.

Functions using an electronic radar-wave sense control, which can detect through any medium such as: wood, cement, brick, glass, paper, cardboard, curtain, etc.

When a thief or intruder comes within about 20 feet of the Electronic Watchdog, it will automatically bark (Woof! Woof! Woof!) imitating a genuine vicious dog. These barking dog alarms will immediately scare away any unwanted visitors. These Electronic Watchdog barking dog alarms can reach a maximum volume of up to 100dB.

Adjustable radar sensitivity and volume controls.
