Dog Barking Alarm Motion Detector,Pir Wireless Human Body Walking Sensor Doorbell Door Security Alert System Device for Home or Office Burglar Deterrent (1Sensor + 1Receiver, White)

I love it, the bark is so real and it scares ppl.. they do a double take looking for the dog, I leave my blinds down in the front so they can't see in my front area.. great product..

i love this gadget, i have it on the DOG mode, it surly is a sound of a real dog. It had different sound modes, like doorbell also. I put it outside by the dood so any one comes by like Mailman or Amazon delivery it barks, so I know there is someone by the door.

I bought this for the dog bark. It went up just great and senses motion through the wall as described. T.he only problem is that it played about 3 times, it began to sounds fake. The first few times it played, it sounded real, like a real dog--it began to deteriorate fast and now it sounds like a recording. Too bad as everything else works wonderfully.

OK so it sounds like a dog sort of. But hey for the price it is well worth it. Motion detection is great for distance and it scares off racoons. Volume isn't the greatest but it still is pretty good, you can hear it through a wood door. Batteries might become an issue haven't had it that long.

The device worked fine from the beginning, although I was not really happy with the sound of barking - it was quite obviously not real if one listens carefully. But for the price, I was ok with that. After a couple of months it stopped working. I replaced batteries in both pasrts of the device - nothing doing. The trasmitter still seems to tramsit as the light goes off when it is triggerred, but the receiver is not responding. Then I noticed a brownish residue behind the batteries compartment of the receiver, as if something leaked from the inside. My receiver stays in the house so it could not have been any dirt or weather impact. I think the receiver went bad for some internal reason. Not a good product if within weeks in stops working.

I have to admit I was skeptical to buy this to chase off the neighborhood cats from peeing on our deck. But, so far out of ALL of the methods we have tried, THIS REALLY WORKS!!! We have the Blink system and we have been able to watch those cats run for the hills!!!

I almost didn't buy this because of some of the reviews mentioning that it was not loud enough. Well they either had bad batteries or maybe the one I got is from a new batch and a new factory or something, but these things are very loud. It accidentally came on while I was setting it up and it was all I could do to get it to go back off because no one could hear the TV! No problem with the volume level here! Since I just received it today I'll add more about longevity, volume levels(which is adjustable), and range, but I just really wanted to get something out there right now to say, "there is no problem with the Volume Level!" IT'S LOUD!!! :)

I had raccoons constantly draining and tearing down my Hummingbird feeder. Nothing worked until this! I had tried light motion detectors, spotlights and spray that was supposed to keep critters away. Finally, this scared the raccoons and they haven't been back. Easy to set up. Some have complained about the sound, but I found no problem with it. It was realistic and loud enough to scare away the night time bandits!
