EVERYBODY LOVES REX! Hes been featured on network TV and Better Homes and Gardens. Its REX Plus.. the barking dog alarm! Everybody seems to love Rex (except surprised intruders), including people who aren't crazy about dogs. Even mailmen love this electronic marvel because he hasn't been blamed for a single case of dog bite. But most of the raves for Rex are from people who depend on it for around-the-clock perfection. From Mansions to Mobile homes, Rex is the perfect watch dog because he what even the best living, breathing watchdog cant do. With his electronic radar eyes, Rex can "see" through thick doors, walls, and glass. Simply plug him in to any 110 VAC electrical outlet, hell stay on duty 24 hours a day! Rex is an ideal security device for homes, apartments, condominiums, mobile homes, RVs, jewelry stores, Retail stores, factories, storage and warehouses - virtually any kind of public or private building. Here Is How Rex Works... You can choose any location indoors where you want to detect motion such as behind the front door. Turn Rex on, set the volume and sensitivity, and he is ready. When motion is detected, Rex begins to emit a realistic, fearful barking sound of a large, unhappy attack dog. The closer the intruder gets, the louder and more frequent the barking gets. As the intruder backs off, the barking lessons in intensity and frequency. Once no motion is detected the barking stops and Rex awaits for further activity. No Problems Of Owning A Real Watch Dog Not only does Rex have powers far superior to any four-legged watch dog, you are spared all the negatives of dog ownership. No license is required, No money and time required for food, supplies, toys, medicines, and vet bills. No No training or obedience classes. No morning or night walks. No furniture or house damage. No messes to clean up. No bite liability. No worries and arrangements when you are not home or are traveling. So Realistic, It Fooled A Professional! A true story. It happened in San Diego not long ago. A customer wrote saying he was actually tickled to tell us he had received a nasty citation for the local Dog Warden! It seems that our gentleman had our Rex, the Electronic Watchdog, guarding his house. The Dog Warden was canvassing the neighborhood to make sure all dog owners had purchased licenses for their pets. He obviously approached the mans house, heard Rex barking and took action. How realistic is the sound of Rex? Realistic enough to fool a trained professional who deals with dogs for a living!
