Very low noise, low blur and true colourisation – note the brown paper bag blowing mid-air. Minimum scene illumination is 0.001lux at F1.5 in colour and 0.0001 lux at F1.5 in monochrome.īear in mind that this camera is designed to shine brightest in the lowest light and I’m undertaking my first test drive in daylight with considerable backlight – the idea is to get a sense of the optical quality of the camera and to assess the performance of the camera engine in daylight conditions – later on tonight I’m going to take a look at night performance and add my findings here. And now, the Deep Learning algorithm also significantly improves the accuracy of Smart functions such as intrusion detection, line crossing detection, human body detection, and auto tracking, etc.WHEN I pull the Darkfighter X out of its crate and install it on a heavy-duty dome camera pendant tripod, my first impressions are its size and heft – this is a robust PTZ camera designed for serious work in external environments.įeatures of Darkfighter X include ½.8-inch dual optical and IR CMOS sensors, integrated 200m IR array, 25x varifocal zoom lens with F1.5 4.8-120mm range with autofocus, -20 degrees to 90 degrees of tilt (Auto Flip), 120dB wide dynamic range, 1080p resolution, IP66 rating, optical de-fog, smart detection functions and H.265+, H.265, H.264+, H.264 and MJPEG compression options. The cameras support H.265+ smart codec, which vastly helps to increase bandwidth performance and lower data storage requirements. Hikvision Darkfighter X technology can provide colourful, sharp images right down to the lowest light levels – in fact to 0.001 lux according to the company. The technology results in colourful, bright, and accurate imaging on security monitors, making night time surveillance video appear nearly as clear as daytime video. The Darkfighter X Series cameras expand upon the human sense of sight by first mimicking the human eye – two distinct sensors capturing and combining brightness and colours – then extending that ability in extremely low-light environments. Critical infrastructure locations are often prime targets for criminals and form ideal locations for the Darkfighter X, including ports, electrical and other power plants, railways, airports, and other travel nodes, and international borders. Tourist areas such as rivers, lakes and beaches, forests, public squares, historical monuments, and more. Applications for this camera and its advanced technology range widely - applications include crime-prone areas of cities after dark: sidewalks and streets, alleyways and retail centres, for example. Video surveillance systems must extend and enhance surveillance capabilities into the darkness in order to reduce the overwhelming amount of night time crime. The result? Darkfighter X renders higher brightness, better color fidelity, sharper edges, and less noise and blur. Hikvision refers to this as bi-spectral technology. The camera combines the two spectrums of light to create video and images – the brightness of the IR sensors imbued with the low-light colour. Both sensors sit behind a single lens, just as the rods and cones in our eyes. While these IR sensors only transmit in black and white, visible-light sensors in the camera are simultaneously detecting and decoding colours – like the cones mentioned above. Infrared sensors in the camera capture reflected Infrared light that is invisible to the human eye but very “bright” to the sensors – similar to the rods in our eyes. Hikvision’s DarkfighterX Series technology was developed from insight into the way human eyes see. Nature did it first, but emerging technology is going further. The brain fuses the information into a single image. The rods respond to brightness while cones capture and identify colours. These two light-sensitive cell types independently perform different functions to capture the visible world around us. In humans, two types of photoreceptive cells – rods and cones – sit on the rear inner surface of the eye, known as the retina. Today, Hikvision is equipping video surveillance hardware aiming to shatter that statistic and take night time video surveillance deeper into the darkness, lifting the cover of night to capture the kind of information that will lead to the prosecution of criminals. To effectively reduce that crime statistic, video surveillance systems must extend and enhance surveillance capabilities into the dark, alerting security personnel before an event occurs. Of all known crimes, 70% happen at night, hidden under cover of darkness.
