Product Description

Safety Technology International - STI ED-50 Rex Plus Electronic Watchdog Barking Dog Alarm. This electronic watchdog alarm never needs sleep, a walk, food or water; yet is always on duty guarding and protecting. 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. Place Rex Plus in any location indoors where you would like him to detect and watch him go. When there is any movement detected, Rex Plus will alert you with the sounds you have chosen. The closer the intruder, the more frequent the sounds. Ideal for homes, apartments, mobile homes, RVs, jewelry stores, hotels, public and private buildings of virtually every kind. Limited 90 day warranty. Safety Technology International, Inc. "We protect the things that protect you"

Rex barks whenever anyone comes near the door and stops as they move out of his range- just like a real dog.

When I first plugged it in I was disappointed like some other reviewers here. It has two problems. First, it sounded like a broken record and second, it saw behind itself better than it saw outside. You are probably wondering why I gave it four stars. Well I have been using this for several months now and it wasn't easy to get it dialed in but it now works great and I want to help others get this work right because it is pretty cool when it does.

First, you need to understand this has 3 barking stages. The first stage is a single woof, as you move closer then the second stage is several woofs, and if you continue to move or get closer then the third is several rapid woofs that blend together. It will continue to repeat stage 3 as long as movement is sensed and after a couple times it becomes obvious it is not a real dog because it sounds like a broken record. To solve this problem you should put Rex in a place that sees the approach but not while the person is waiting at the front door. I am fortunate that my living room is about 3 feet in front of the front door so it will not continue to bark at stage 3 while the person is waiting at the front door.

The bark doesn't sound so realistic inside the house but through the wall it sounds very realistic as you approach it. I have had guest ask me where the dog is when I open the door. I actually have a well mannered Labrador Retriever but she never barks at people and she is normally asleep in the backyard anyway.

I fixed the other problem of it seeing behind itself by making a metal shield using a piece of 24 gage stainless steel cut 10" by 16" and shaped it into a curve. It would sometimes bark when I was upstairs directly over it so I added a piece of stainless to go over the top and this did the trick.

I've had mine about 6 months. Sure, it takes a bit of time to position it just the way you want; sooo? Big deal if it barks when I'm leaving the house; I just say, "Guard the house." hahaha. Sounds just like a german shephard and scares the mailman.
A cop friend of mine said that it's great for a single person living alone, and no burglar is going to waste their time trying to decide if it IS or if it ISN'T real, when they can go to the next house that DOESN'T have a dog.

Rex is omni-directional. It detects motion in all directions. Sometimes I think that it may even detect birds landing on the roof above it. Since I have a cat, the only place where I could put Rex was the garage. To my surprise, my garage door, which was made of synthetic material (most likely fiberglass), totally blocked the signal, but Rex went through stucco walls really well. I placed it next to the wall. It covered the part of the driveway leading up to my front porch, the front porch itself and beyond. I said "beyond", because Rex even detected motion in the kitchen on the other side of the porch. It barked when I moved around in the kitchen. I didn't mind during the daytime, but the barking became annoying in the middle of the night, when I got up and fixed a snack. I was afraid of waking up the neighbors. My solution was "remote controlled Rex". I plugged it in a wireless remote switch (also bought at amazon.com) and turned it on and off from the kitchen. The barking does sound mechanical and repetitive, when one takes time to listen to it carefully, but I doubt that an occasional burglar will stick around and listen to the Rex. It is not as good as a real dog, but it will do as a burglar deterrent. By the way, if you want to get a real dog, please go to your local animal shelter for one. Don't buy it from a pet shop.

The electronic sound of a dog barking does not sound like a real dog. The sound is distorted and sounds electronic. It fools people initially, but if they hang around, they soon catch on that it is not a real dog. Perhaps it may be just enough to deter a burglar though, and that would make it worth it's expensive price.

The device monitors an outside area, but it monitors the inside area even better. This means that everytime you go near it, even while inside the house, the alarm activates, which you don't really want it to do. I tried putting heavy books around the back and sides of it, but it still activated everytime I went near it while I was inside the house. Ideally, you would need to place it somewhere that you do not go near while you are at home, or else only activate it when you go away from home.

The good news is you don't have to clean up after it or feed it, and it stops barking when you turn the juice off.

It's very easy to set up, just plug it in and adjust the sensitivity and volume control knobs, that's it!

Despite it's shortcomings, I may even buy another one for my side door as I am paranoid about burglars. It does have a wow factor when your neighbors learn about it. I don't know of anything else quite like it on the market.

Rex is a motion-sensing noise-maker, that increases the barking intensity/frequency as 'intruder' advances. Rex does that very well and very realistically. Works great when I work late alone or when I travel. Rex also travels with with a prominently placed heavy chain leash and large partially-chewed rawhide bone, to complete the illusion.

COULD someone stay around for several minutes (or make repeat visits) and eventually figure out it's probably not a real dog? Sure. But It isn't that easy to figure out WHERE the sound is coming from and it takes time to FIND IT to try and shut it up. (Try out new positions, don't always keep Rex in the same place.)

Unless your dog is specially trained, it may not alert you to an intruder, or may not be able to defend ITSELF from an intruder. (A Rex can't be bribed by food.) So be smart and realistic when thinking about your safety options. Rex also has a pleasant rainforest/bird setting, if you just want to know someone has entered a certain area. I've given away three as gifts over the years to people who needed a little extra security.

And, of the eight people Rex 'warned' me about during our years together? Not one approached after the first bark.
