What is the input of a burglar alarm?
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. Input devices such as smoke or fire sensors and water leak sensors are special types of sensors that are always active.
What three types of intruder alarms can be used in a security system?
