This item goes off all the time with no barking! my dog is a freaking mess now, I didnt realize it went off here and there without barking. horrible, I didnt realize it until I put the setting where I could hear when it went off. One upside, now my dog isnt barking as much, just with it in view, LOL.This would go off when my 3yr old would laugh, when we would shut a door, flush a toilet, walk heavily, and our dog was shaking all the time!
