Swann PRO-642 Multi-Purpose Day/Night Security Camera, 700 TV Line Camera Resolution, 85' Night Vision, CCD Image Sensor, Weatherproof

The Swann PRO-642 Multi-Purpose Day/Night Security Camera is sensitive to light and therefore, can make use of even the smallest amount of light to provide an image. In low light, this comes through as a black and white image. In complete or near-total darkness, the camera uses built-in infrared LEDs to illuminate the area in front of it. This light is invisible to the human eye, although you might notice a faint red glow coming from the front of the camera, which is normal. It has an OSD (On-Screen Display), that you can access to change various options for image quality, white balance and shutter speed.
