This IR808HS premium CMOS camera comes with 520 TVL high resolution. Built in dual-filter day & night auto switching, the camera can switch to black and white on low light to enhance sensitivity. With heat dissipating, weatherproof metal housings, its perfect for both indoor and out door installations. Notes: Near-infrared light is beyond what the human eye can see, but most camera sensors can detect it. Therefore color camera in daylight without an IR-cut filter will see a significant amount of infrared light resulting in strange colors. With a Mechanical IR-Cut Filter Switch, this camera uses an IR-cut filter during the daytime. 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, built in IR illuminator active, the IR-cut filter is removed, allowing the camera detect infrared light reflect from the object.
