The IR808HS is a high-resolution, premium CMOS camera with 520 TV lines of   resolution. 2012 model built in with dual-filter day & night auto switching,   the camera will switch to black and white on low light to enhance sensitivity.   With heat dissipating, weatherproof metal housings, it's 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, color camera in daylight without an IR-cut filter will therefore see a significant   amount of infrared light resulting in strange colors. With a Mechanical IR-Cut   filter switch, during the day this 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, built in IR illuminator   active, the IR-cut filter is removed, allowing the camera detect infrared light   reflect from the object.
