ED-55 - Rex Plus II Electronic Watchdog

Rex II, the electronic watchdog alarm, never needs sleep, a walk, food or water, yet is always on duty guarding and protecting. In addition to the choice of a ferocious dog(s), Rex II also offers a siren or greeting announcer. 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, Rex II can "see" through thick doors, walls and glass. Once his cord is plugged into any standard 110 VAC electrical outlet (or install six C batteries), he'll stay on duty around the clock.

When Rex II detects movement, he starts to emit the sound you have selected. The closer the intruder gets, the more frequent the barking becomes. As the intruder backs off, the barking decreases in frequency, stopping completely when movement is out of range

I own a jewelry store. I have a regular alarm system. But I put this in the back room and when someone walks by the side window, They think i mad dogs in the building. Its funny just to peoples reactions. This will keep the regular thief away for sure.
