Detailed explanation-1: -What is a Burglar Alarm System? A burglar alarm system consists of a series of electrical components that are connected to a property. Via sensors and contacts, they detect movement or the opening of doors and windows, upon which a loud alarm is produced to alert those nearby of the unauthorised entry.
Detailed explanation-2: -They are also less secure than an access control system because many of the devices, such as motion detectors and glassbreak detectors, don’t trip until the burglar is entering the facility. Burglar alarm systems are NOT access control systems!
Detailed explanation-3: -Input Devices – These are motion detectors, door and window sensors, as well as glass break sensors. When someone breaks into your home, these sensors will activate your security alarm system.
Detailed explanation-4: -An active infrared motion sensor emits infrared light from the end and the receiver on the other end receives the signal. If that electrical beam is cut off by any object between the emitter and the receiver, it triggers the alarms.
