Hikvision DarkFighterX 4MP PTZ Camera Review 35 The beautiful looking lens is coated with Magnesium Fluoride. The wide end of a big PTZ like this tends to be longer than most other cameras – in this case the wide horizonal angle of view is 58.9 degrees, while the narrow end is 2.2 degrees. Hikvision’s high end cameras have sweet lenses – this one has an aperture range of F1.6 at the 5.9mm wide end and F4.4 at the 206.5mm long end. You wouldn’t use all this digital zoom but being able to creep a little closer with the glass at full stretch can be beneficial in CCTV applications. If 35x optical isn’t enough, there’s 16x digital as well. According to Hikvisions’s Cecil Nie, that size in part comes down to the need to accommodate a bigger 35x optical lens capable of identifying a 1m long object at 260 metres with a resolution of 250 pixels. When I saw DarkfighterX PTZ at Security 2019, the first thing that struck me was its increased size. Given Hikvision engineers tend to chase the specification hard, it’s likely the delivery of this performance comes thanks to a lot of digital work in the background, as well as a slower shutter speed in low light.ĭarkfighterX also offers deep learning technology to deliver greater accuracy with analytics such as intrusion detection and line crossing – video analytics works better the less pixel spread you have across a scene, which means this 4MP camera with 2688 x 1512 pixels should offer solid performance. We’ve never seen what the sensor of a DarkfighterX looks like – it’s probably hard to distinguish from the any other 1/18th of an inch CMOS.ĭarkfighterX 4MP’s sensor is said to deliver colour images at 0.0005 lux, which is a big call for an image not enhanced by 250 metres of IR – starlight is. The 2 data streams are combined by the camera engine to deliver optimum colour and clarity. The interesting thing about DarkfighterX technology is that it uses a lens and sensor to capture colour, while another lens and sensor captures light – and this takes place on the sensor board itself. The 4MP DarkfighterX PTZ (the model number is DS-2DF9C435IH-DLW) effectively doubles the resolution of the previous model, which had excellent performance in its own right. Hikvision’s Darkfighter X PTZ is among the best CCTV cameras in the industry, so when offered the chance to take a look at the latest 4MP IR DarkfighterX PTZ, we didn’t hesitate. Features of Hikvision DarkfighterX 4MP PTZ include:.Hikvision’s DarkfighterX 4MP PTZ combines an excellent sensor engine offering solid low light performance and high resolution with a brilliant lens and long range IR to create a surveillance tool of unprecedented power. ![]()
