The infrared led array has a wider emitting angle than traditional infrared leds. Traditional infrared leds can only emit the active infrared ray in a narrow angle. When there is a security camera with infrared led array, the emitted infrared will cover the whole surveillance area, which means the infrared led array camera can see the whole area in a dark environment such as at night.

Function seeking to compensate the backlight events in order to prevent the camera from dazzling with great intensity of light received and so produce an unsatisfactory image. AWB may be entirely sufficient for camera positions with non-traditional environmental illumination changes.

To determine the overall video brightness, it is necessary for cameras to be able to measure an actual scene illumination, being auto-iris the most advanced and commonly used method nowadays. In order to get this, the camera measures the light level and then adjusts the motorized iris in the auto-iris Lens.

This feature delivers a sharp image in low light and nighttime conditions. There is also real solution to day and night surveillance applications that deliver clear and sharp color images in illuminant areas and black and white images in dark areas using infrared illumination, without the need to refocus the lens.
