You can know when someone ” crosses the line”. This high tech device creates an invisible infrared beam up to 60 ft. long. When the beam is crossed a loud alarm or a pleasant chime sound will be emitted. Can be used as an invisible playpen to alert you to your child or pet leaving a safe area. The alarm can also be used at night to scare off would-be intruders. In the chime mode, retail stores in businesses can use it to announce customers and alert them when someone enters an area that is “off limits”.

1 Star Piece of junk
I read a previous review that this thing was a piece of junk but ignored it anyway. Well, I should have listened. I own a business and needed a “fitting room” type sensor to alert me when customers came through the door. I thought that this device was doing the job although it was annoyingly loud even at its lowest setting. However, it stopped working after 2 weeks. I returned it and although was kinda PO’d that I had to pay to ship it back, I was hopeful that the thing was just a lemon and the next one I would get one would work. I was wrong. The second one stopped working, too!
