2. Passive infrared sensor - Wikipedia

   en.wikipedia.org/wiki/Passive_infrared_sensor

   Since PIR sensors have ranges of up to 10 meters (30 feet), a single detector placed near the entrance is typically all that is necessary for rooms with only a single entrance. PIR-based security systems are also viable in outdoor security and motion-sensitive lighting; one advantage is their low power draw, which allows them to be solar-powered.

3. Security alarm - Wikipedia

   en.wikipedia.org/wiki/Security_alarm

   PIR sensors identify abrupt changes in temperature at a given point. As an intruder walks in front of the sensor, the temperature at that point will rise from room temperature to body temperature and then back again. This quick change triggers the detection. PIR sensors designed to be wall- or ceiling-mounted come in various fields of view ...

4. 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.

5. Photoelectric sensor - Wikipedia

   en.wikipedia.org/wiki/Photoelectric_sensor

   Remote photoelectric sensors used for remote sensing contain only the optical components of a sensor. The circuitry for power input, amplification, and output switching is located elsewhere, typically in a control panel. This allows the sensor, itself, to be very small. Also, the controls for the sensor are more accessible, since they may be ...

6. Infrared detector - Wikipedia

   en.wikipedia.org/wiki/Infrared_detector

   Prototype of high-speed infrared detector installed on the PIONIER instrument at ESO’s Paranal Observatory. [1]An infrared detector is a detector that reacts to infrared (IR) radiation.

8. Camera trap - Wikipedia

   en.wikipedia.org/wiki/Camera_trap

   A camera trap with a passive infrared (PIR) sensor. A camera trap is a camera that is automatically triggered by motion in its vicinity, like the presence of an animal or a human being. It is typically equipped with a motion sensor—usually a passive infrared (PIR) sensor or an active infrared (AIR) sensor using an infrared light beam. [1]
