Infrared (IR) Cut Filters allow for a sharper quality picture, more accurate colors, and better overall image quality day or night. Cameras with IR Cut Filters deliver color images during the day. As light diminishes below a certain level, the camera can automatically switch to night mode to make use of near infrared (IR) light to deliver high-quality, black and white images. During the day, a day and night camera uses an IR-cut filter. IR light is filtered out so that it does not distort the colors of images as the human eye sees them. When the camera is in night (black and white) mode, the IR-cut filter is removed, allowing the camera’s light sensitivity to reach down to 0.001 lux or lower.
