The sensor beams create an invisible field that sounds an alarm if someone strays into it. Excellent for protecting specific areas around your home.
Motion sensor alarms are used to detect the presence of someone or something in an area where they shouldn’t be. By using infrared technology, these devices can sense when someone walks in front of them and will sound an alarm to alert the owner. More than one sensor can be used around the home or business to protect a very large area. Some alarms will even call a phone number when triggered letting you know something is wrong.
