Adaptive IR technology whitepaper
Lighting is one of the most important factors in image quality. As it gets darker, a surveillance camera’s ability to capture evidentiary detail such as faces and licence plates rapidly decreases. In order to overcome this, artificial sources of light can be added to the scene, the most common of which is Infrared (IR) illumination.
While the human eye can detect visible light in the ranges of 390 to 750 nanometer (nm), IR light is at a higher wavelength (typically 850 nm), making it invisible to the human eye while providing the camera the ability to “see.” Since IR light has a higher wavelength than the colour spectrum, the resulting image will be in monochrome (black and white), but can capture crucial detail in complete darkness.
