This camera is an affordable economic day night audio video CCTV CMOS security camera. Built-in 36 infrared LEDs are used for night vision. Capture color pictures by day and excellent images at night. Connect easily with DVR or TV for monitoring. 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. Camera selection tips: A CMOS image sensor is sensitive to light but is not sensitive to color; entry level CMOS camera does not have accurate color reproduction. Low light sensitivity is more important for security surveillance applications. If color reproduction is more important to your, please select a CCD bullet camera without IR.
