PSI PRODUCT REVIEW 2018 Hikvision Hikvision DarkfighterX is the ultra-low light surveillance camera technology range which displays full colour images 24/7. The innovation is inspired by retinal imaging and the human eye’s ability to independently process colour and brightness H DARKFIGHTER X Sharp colour images at low light levels ikvision, the world’s leading supplier of innovative video surveillance products and solutions, has created the next level of night surveillance with the latest upgrade of its DarkFighter technology – the DarkFighterX series. The technology can provide colourful, sharp images right down to the lowest light levels – in fact to 0.001 lux. This series takes colour to the max by taking inspiration from the way the human eye works. Eyes use different cells to collect colour and brightness information, which the brain then merges. The DarkFighterX cameras take information from an IR sensor (for brightness) and information from a visible light sensor (for colour) and combines them to provide the best of both worlds – one bright fullcolour image. Traditional cameras could either provide bright images that were blurry, or images in monochrome. The new technology seamlessly melds the two, so neither will be an issue for image quality again. “It’s a fact that 70% of crimes happen at night, but with DarkFighterX, that’s no problem,” says Peter Guan, Hikvision’s Channel Sales Director. “Faces are sharper and easier to recognise and the surroundings much clearer to see, even in the lowest light. All of this makes images much more valuable for evidence collecting and case solving.” The DarkFighterX series includes a PTZ and bullet camera. Both come with optical defog, 25X optical zoom, 2MP resolution and smart detection. They also boast the new H.265+ codec and are weatherproof to IP66 standard. They are at the cutting edge of security technology and are particularly useful in applications that require 24h full-colour images, like cities - streets, squares and parks; outdoors - rivers and forests; and transportation – railways and ports. The two cameras in the Darkfighter X range are the speed dome (DS-2DF8225IH-AEL) and the outdoor camera (DS-2CD5028G0/E-HI) both utilising the dual patented sensor design to process colour and brightness independently. The Hikvision DS-2DF8225IH-AEL Darkfighter X 2MP 25 IR network speed dome adopts 2 1/2.8" progressive scan CMOS chips. With the 25x optical zoom lens, the camera offers more details over expansive areas and operates at Colour: 0.001lux/F1.5, B/W: 0.0001ux/F1.5. The unit can also work with H.265+, H.265, H.264+, H.264 and MJPEG. Meanwhile the DS-2CD5028G0/E-HI camera boasts a 1/ 2.8" progressive scan CMOS and 1920 × 1080 at 30fps footage. Other features include: 1 RS485, 2 alarm inputs /outputs, 1 audio input/output, operating condition: -40 °C to +60 °C (-40 °F to +140 °F), H.265, H.264 and up to 100m IR range. www.hikvision.com/europe/ “It’s a fact that 70% of crimes happen at night, but with DarkFighterX, that’s no problem.
