Often the thinking seems to be that these bigger PTZs will be pole or wall mounted well out of harm’s way and there’s truth in this. This latter is rather unusual in top-line PTZ of this size. Important for a camera with designs on dominating external applications, Hikvision’s DarkFighter PTZ is protected by an IP66 rating against rain and dust, as well as being rated to IK10 against vandalism. And with 200m IR capability, Darkfighter PTZ brings some big guns to the party. I didn’t see this sort of see-in-the-dark low light performance in our test though I can confirm the full body Darkfighter is very strong down to 5 lux in street surveillance applications, giving face recognition to about 5m at 7 lux. The company talks about getting colour(!) images down to 0.0005 lux, which is way less than the 0.002 lux of starlight. I saw the unit resolving license plates effortlessly at 200m and apparently the Hikvision Australia team expects performance to be at least 300m, which is really something. Something else Hikvision claims is that the new camera allowed license plates to be read at distances of hundreds of metres and yes, I can confirm this is true. Importantly, a lens that works well in low light is not necessarily a great lens in backlight or in daylight but the Darkfighter PTZ, like its full body sibling, handles daytime as well as any other 1080p camera. The wide F1.2 aperture on a lens with a focal range of 6-136mm is going to be contributing to low light performance, too. My sense is that Hikvision’s wholly-owned lens manufacturer is using superior lens material as well as coatings that are optimised for low light, and possibly a simpler internal design to reduce attenuation of light passing through the lens to the sensor. Exactly what this means from a technical perspective is a bit uncertain. There’s also support for ONVIF, PSIA, and CGI standards allowing integration with other video surveillance equipment and systems.ĭarkfighter PTZ employs the company’s ultra-low-light MP lens that’s designed specifically to capture sharp color and monochrome images in extreme, low-light conditions. MPEG4, MJPEG and H.264 video compression formats are supported and the camera features multiple H.264 compression profiles, allowing users to optimize bandwidth and storage without compromising image quality. There’s 120 dB WDR (Wide Dynamic Range) and Hikvision's 3D DNR (Digital Noise Reduction) technology, along with a 23x optical zoom. In terms of general specifications, DarkFighter PTZ has a 2MP, 1.9-inch high definition progressive scan CMOS image sensor. You’d need to look at a number of top cameras side by side to be sure, but the Darkfighter PTZ is right up there at the top. This is a big claim but looking at the images, I think it’s justifiable. It’s a handsome unit, robustly built and nicely balanced in appearance.Īccording to Hikvision, the DS-2DF8223I-A(AEL) Darkfighter PTZ is the world's first 1080P Full HD ultra low illumination network PTZ that delivers full colour images in conditions the company says would defeat conventional monochrome IP cameras and competing low-light cameras. WE’VE talked about Hikvision’s Darkfighter PTZ in SEN before but I’ve never seen it in action, so it’s off to the Hikvision head office in Sydney to check out this low light PTZ. The DarkFighterX series cameras can be widely used for wide ranges of high-definition, especially where needs 24h color-full images, such as street, the rivers, forests, roads, railways, ports, squares, parks, etc.New from Hikvision is Darkfighter PTZ, which combines a large CMOS sensor, strong WDR, a quality 23x zoom lens and 200m IR range to offer a solution of serious power. And then these are combines into one full-colour image.Ī Revolutionary Technology for Ultra-low Light Environment This series has innovative dual-sensor design, on sensor for IR imaging that gurantees image brightness, the other sensor for visible light that guarantees vivid colour. Hikvision strives to get ever more effective information about suspects and vehicles, such as: facial features, height and clothing colour of a suspect and plate number, colour and brand of a vehicle. Hikvision's DarkFighterX series is based on the retinal imaging that eyes independently use to process colour and brightness. 70% of crimes happen at night.
