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.
DARKFIGHTER X HIKVISION SERIES
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.
