These go off everything that happens even if it's the wind blowing Works ok Does everything it is supposed to do It doesn't seem to be workeing unless I'm standing next to the sensors with the box... and mine didn't come with a manual so I'm not even sure what I'm doing wrong? this works nicely and lets you know if some one is coming. I use it for pet detection when my dog is at the door which means he needs to go out!! its great! Placement is key to making this work I have been moving it all over so I get coverage I want, Like most people say it is sensitive to wind and random motion so finding a way to... It's okay, the alarm sound is not as loud as I would have liked. And, there is not delay on the alarm setting so you can get out of the room or door. At night the product is useless because it cannot see you even though there is light outside. During the daytime sometimes it catches a person and sometimes it doesn't. I use them in the window and it surely will let you know if the window is touched. So, for that reason I like it. The downside is that it is super sensitive.
