   en.wikipedia.org/wiki/Forward-looking_infrared

   A FLIR Talon multi-sensor camera system equipped with an infrared laser pointer (which is invisible to casual observers) for illumination purposes was used to gather data at night. [15] The American Civil Liberties Union raised concerns over the fact that new surveillance technology is implemented without judicial guidance and public discussion ...

4. Full-spectrum photography - Wikipedia

   en.wikipedia.org/wiki/Full-spectrum_photography

   Full-spectrum photography is a subset of multispectral imaging, defined among photography enthusiasts as imaging with consumer cameras the full, broad spectrum of a film or camera sensor bandwidth. In practice, specialized broadband/full-spectrum film captures visible and near infrared light, commonly referred to as the "VNIR". [1]

   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.

6. Pose tracking - Wikipedia

   en.wikipedia.org/wiki/Pose_tracking

   In optical tracking, cameras are calibrated to determine the distance to the object and its position in space. Optical systems are reliable and relatively inexpensive, but they can be difficult to calibrate. Furthermore, the system requires a direct line of light without occlusions, otherwise it will receive wrong data.

7. Automotive night vision - Wikipedia

   en.wikipedia.org/wiki/Automotive_night_vision

   Active systems use an infrared light source built into the car to illuminate the road ahead with light that is invisible to humans. There are two kinds of active systems: gated and non-gated. The gated system uses a pulsed light source and a synchronized camera that enable long ranges (250m) and high performance in rain and snow.
