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)

Famous quotes containing the word motion:
“Too many Broadway actors in motion pictures lost their grip on success—had a feeling that none of it had ever happened on that sun-drenched coast, that the coast itself did not exist, there was no California. It had dropped away like a hasty dream and nothing could ever have been like the things they thought they remembered.”
—Mae West (1892–1980)
