home security alarm system
That can create a dangerous situation where you come face to face with a burglar in your hallway. Door and window transmitters are the only way to detect break ins immediately. Don’t let anyone convince you that motion detectors alone are a substitute for them. Glass breakage sensors
are available too, but are optional. Most burglars only break glass in order to unlock a door
or window. Then, when they open the door or window, a standard transmitter will detect the entry.
