Motion sensors are electronic devices used to detect nearby people or objects. When these devices pick up motion they send an alert to the security system.
Types of Motion sensors include:
Passive Infrared- detect body heat or infrared energy by looking for changes in temperatures.
Microwave – sends out microwave pulses and measures their reflections off moving objects.
