Hikvision is expanding their DarkFighter range of ultra-low-light surveillance cameras with the DS-2DF8223I-AEL PTZ network camera. This cutting-edge camera utilises Hikvision’s industry-leading, ultra-low-light MP lens and is designed specifically to capture sharp color and monochrome images in extreme, low-light conditions. The result is crystal-clear color images in conditions that would defeat most conventional monochrome IP cameras and competing low-light cameras.     Features: 1/1.9” HD CMOS sensor 2MP(1920*1080)
