Rex® II is versatile and provides an excellent way to deter burglars, without the annoying problems of owning a real dog. With his electronic radar eyes, this barking dog alarm can "see" through thick doors, walls and glass. When Rex II detects movement, he starts to emit the selected sound. The closer the intruder gets, the more frequent the barking sound (when selected). As the intruder backs off, the barking decreases in frequency, stopping completely when movement is out of range. This barking dog alarm has also been known to scare a bear or two. Rex II also offers siren or greeting alternate sounds. For use outside of UK and Europe.
