A day and night camera is designed to be used in outdoor installations or in indoor environments with poor lighting and delivers colour images during the day. As light diminishes below a certain level, the camera automatically switches to night mode to deliver black and white images. Higher end Day night cameras use an IR-cut filter. IR light is filtered out so that it does not distort the colours of images as the human eye sees them. When the camera is in night mode, the IR-cut filter is removed, allowing the camera’s light sensitivity to reach down to 0.001 lux or lower without any Focus shift.
