Motion Detection

Motion detection is the process of detecting a change in position of an object relative to its surroundings or the change in the surroundings relative to an object. Motion detection can be achieved by both mechanical and electronic methods. When motion detection is accomplished by natural organisms, it is called motion perception.

Motion can be detected by:

Infrared (Passive and active sensors)
Optics (video and camera systems)
Radio Frequency Energy (radar, microwave and tomographic motion detection)
Sound (microphones and acoustic sensors)
Vibration (triboelectric, seismic, and inertia-switch sensors)
Magnetism (magnetic sensors and magnetometers)
