Feature 5



Rex Plus® is the electronic watchdog that never sleeps and the soothing sounds of the rainforest! Choose from four settings: continual tranquil sounds of the rainforest, alert sound of an angry and protective watchdog, soothing sounds to alert you of a guest's arrival, and alert sounds of both the angry watchdog and a warning siren. Rex Plus can "see" through thick doors, walls and glass. Once you plug his cord into any standard 110-VAC electrical outlet, he'll stay on duty around the clock. Ideal for homes, apartments, mobile homes, RVs, jewelry stores, hotels, public and private buildings of virtually every kind.

Choose any location indoors where you want to detect movement such as hidden behind the front door. Turn Rex on and he begins detecting. When movement is detected, Rex Plus will alert you with the sounds you have chosen.

Barking Dog Alarm
I bought my first Rex Barking Dog alarm 3 years ago and was so impressed I have bought 2 more since then and bought one for a good friend of mine. I use all three of them on all three levels of my home; I sleep a lot better at night now.

STI-ED-50 Barking Dog Alarm
I’ve already bought 3 of these. Two for our house and one for brother-in-law. So you see how well we like this product. Not only keeps burglars at bay, it works to keep cats from urinating on my front door!

This is a Great item. We turn it on whenever we go shopping or just for a walk. The sound of Rex barking leaves a strong feeling, that there is something behind that wall and if I were a robber would think twice before entering. I wish that it had a 360 degree beam to cover doors in front of the unit and windows behind the unit. Let me know if one becomes available.
