Review on 🐕 Safety Technology International, Inc. ED-50 Rex Plus Electronic Watchdog: Powerful Barking Dog Alarm for Enhanced Security by Logan Tripp

I have two of these. They're the best out there, but the downside is that the speakers feel quiet. My friend and I thought that the audio recording was interrupted, but it turned out that the speaker or the electronics had failed (the volume is too high, so you hear a strange vibrating noise). As a result, you hear the dog bark once, you come closer, it barks several times, you come even closer and it starts barking, but this angry barking is a bit louder and you hear a buzzing due to this technical error. and it lets you know that the dog is not real. This is a detailed explanation of this whole "This sounds wrong. NO, that sounds REAL" which you keep seeing in these reviews. If you lay this thing on its side (try both sides, it varies) and attach the speaker to something to constrain it (one thing, one thing I've tried is tape around the speaker) the hum will decrease, if you turn the volume down the hum will also be eliminated by the lower volume but then it's too quiet to really work like a dog so you need to hook it up to an amp or mic but there is no sound.Sockets to plug everything in so that's my next idea.If I get a chance I'll make an "out" connector on it by using solder the wires from the speaker to the radioshack headphone jack the sound of the dog is TERRIBLE my beloved dog and he is big and through a thick wall the sound is 90% more real even with buzzing but when I put the su mmen can get rid of, this product is an idea. The positioning of this thing is also an issue in the back as there is steel in my doors blocking the sensor. I need to place it a few feet behind and to the side of the door and then increase the sensitivity so it covers an area wide enough to cover the door. If I put it next to the door, on the floor or against the wall, it doesn't see people at the door, only people on the side of the door. Get creative with the range and location settings and play around with it for half an hour, trying different ranges and locations until you find one that works for your door. And it's annoying that you can't avoid triggering it when you're moving around the house, but I don't care because I use it for vacations when there's no one around the house.
