Swann PRO-642 Multi-Purpose Day/Night Security Cameras, 700 TV Line Resolution, 57deg. Viewing Angle, 82' Night Vision, 2 Pack

The Swann PRO-642 Multi-Purpose Day/Night Security Cameras (2 Pack) are 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, these cameras use 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.
