2. Infrared photography - Wikipedia

   en.wikipedia.org/wiki/Infrared_photography

   Cameras sensitive to longer infrared wavelengths including those used in infrared astronomy often require cooling to reduce thermally induced dark currents in the sensor (see Dark current (physics)). Lower cost uncooled thermographic digital cameras operate in the Long Wave infrared band (see Thermographic camera). These cameras are generally ...

3. Forward-looking infrared - Wikipedia

   en.wikipedia.org/wiki/Forward-looking_infrared

   Forward-looking infrared (FLIR) cameras, typically used on military and civilian aircraft, use a thermographic camera that senses infrared radiation. [ 1 ] The sensors installed in forward-looking infrared cameras, as well as those of other thermal imaging cameras, use detection of infrared radiation, typically emitted from a heat source ...

4. 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.

5. Full-spectrum photography - Wikipedia

   en.wikipedia.org/wiki/Full-spectrum_photography

   The longwave infrared light may also wash out a considerable amount of the visible light in the blue and green areas in a full spectrum photograph. Similarly if infrared light is entirely blocked, the visible light can overwhelm the recording of the ultraviolet light. So there is no truly full-spectrum photograph that can be made.

6. Image intensifier - Wikipedia

   en.wikipedia.org/wiki/Image_intensifier

   An image intensifier or image intensifier tube is a vacuum tube device for increasing the intensity of available light in an optical system to allow use under low-light conditions, such as at night, to facilitate visual imaging of low-light processes, such as fluorescence of materials in X-rays or gamma rays (X-ray image intensifier), or for conversion of non-visible light sources, such as ...

7. Day and night camera - Wikipedia

   en.wikipedia.org/wiki/Day_and_night_camera

   A day and night camera is a security camera that can see the picture during the day hours, when there is enough sunlight, and during the night in total darkness or minimum illumination. A day and night camera has special lenses that allow infrared emission produced by infrared LEDs and reflected from objects to go through and reach a CCD or ...
