Swann SWPRO-A856 analogue high definition (AHD) 1080P 2MP CCTV dome camera. For use with the Swann 4600 Series of CCTV Recorders, it uses coax cable and is known as AHD which is analogue high definition. This Dome camera is a perfect addition to any 4600 series kit. Being a dome these look more subtle than a bullet camera with the same performance. This camera, like others has Infrared LEDs mounted around the lens allowing the camera to operate in complete darkness with a reasonable distance up to 25Metres, obviously additional light from Sensor lights or street lights can assist the camera see further at night. During the day the camera can see as far as you. The Camera has a good 70° viewing angle, this angle of view suits most applications giving good coverage without sacrificing quality - remember the wider the angle the less detail, the narrower the angle improves detail with less coverage.
