  2. Motion detector - Wikipedia

    en.wikipedia.org/wiki/Motion_detector

    A motion detector attached to an outdoor, automatic light. A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection).Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.

  3. Motion perception - Wikipedia

    en.wikipedia.org/wiki/Motion_perception

    These sensors are described as detecting motion by spatio-temporal correlation and are considered by some to be plausible models for how the visual system may detect motion. (Although, again, the notion of a "pure motion" detector suffers from the problem that there is no "pure motion" stimulus, i.e. a stimulus lacking perceived figure/ground ...

    However, initial size, power consumption and price had prevented their mass adoption in consumer electronics. While there are other kinds of motion detector technologies available commercially, there are four principle types of motion sensors which are important for motion processing in the consumer electronics market.

    A PIR motion detector used to control an outdoor, automatic light. A camera trap with PIR motion detector. An indoor light switch equipped with PIR-based occupancy sensor [1] A PIR-based motion detector is used to sense movement of people, animals, or other objects.

  6. Unattended ground sensor - Wikipedia

    en.wikipedia.org/wiki/Unattended_ground_sensor

    The gateway bridges U-UGS sensor field to the FCS network and relays motion alarm and image data. It's capable to be monitored locally by a soldier or remotely through a FCS network enabled modulevehicle. The intrusion node is a motion sensor that detects movement and is able to tell the difference between animal and human beings.
