There are non-triggered cameras that either run continuously or take pictures at specific time intervals. The more common ones are the advanced cameras that are triggered only after sensing movement and/or a heat signature to increase the chances of capturing a useful image. Infrared beams can also be used to trigger the camera.
Infrared sensing snakes use pit organs extensively to detect and target warm-blooded prey such as rodents and birds. Blind or blindfolded rattlesnakes can strike prey accurately in the complete absence of visible light, [13] [14] though it does not appear that they assess prey animals based on their body temperature.

A passive infrared detector mounted on circuit board (right), along with photoresistive detector for visible light (left). This is the type most commonly encountered in household motion sensing devices and is designed to turn on a light only when motion is detected and when the surrounding environment is sufficiently dark.
In January 2015, IEEE 802.15 formed a Task Group to write a revision to IEEE 802.15.7-2011 that accommodates infrared and near ultraviolet wavelengths, in addition to visible light, and adds options such as Optical Camera Communications and LiFi. [12]
Digital camera sensors are inherently sensitive to infrared light, [42] which could interfere with normal photography by confusing the autofocus calculations, because infrared light wavelengths may focus at a different point than visible light wavelengths, or by softening the image, if the red channel becomes oversaturated.
When OnePlus announced its 8 Pro smartphone, it included details about a curious camera that it calls the Color Filter camera. In reality, it’s an infrared (IR) camera that can pick up a part of ...
