Microwave Doppler Radar Motion Detector: Also a portable motion sensor that runs on a 9-volt battery. It detects motion based on reflected microwave signals. It transmits a signal and “listens” to what’s reflected back to it. Movement changes that signal and the alarm is triggered. This detector can “see” through, and detect motion through, most walls and doors!
