What is DarkFighterX
Why we need DarkFighterX in surveillance
The average human eye detects visible light wavelengths around 500nm. In contrast, image sensors sense visible and infrared light, whose wavelength range is longer than 700nm.
Conventional cameras have limited vision in extremely low illumination environments with no visible light. As a result, they produce poor image quality with large amounts of visual noise.
Infrared light is essential to supporting the camera to lower image noise, producing clear images. However, true colour can’t be guaranteed.
How does it work?
DarkFighterX technology adopts Hikvision’s SpecEX technology to combine a scene’s colour and brightness data. It then renders accurate and detailed high-definition images in extremely low-lit conditions.
Cameras using DarkFighterX are equipped with a dual-sensor structure that works independently.
- Cone sensor – This sensor acquires visible light to collect colour data
- Rod sensor – captures infrared light to gather brightness details.
Both infrared and visible light are significantly enhanced.
DarkFighterX cameras have high-light sensitivity and resolutions while providing clear images and true colour.
DarkFighterX cameras use the supplement infrared light in extremely low illuminated environments. Visible light and infrared light enter separate image sensors, forming two images.
The two images are then processed by the unique image signal processing (ISP) and Hikvision image fusion algorithm, resulting in an image of higher brightness and signal-to-noise ratio (SNR).
The challenge for CCTV in low-lit areas
Imaging in low illumination has always been challenging in the video surveillance industry. Although some cameras meet the basic requirements for surveillance, they fail to work well in extremely low-light environments.
Switching to infrared mode leads to colour data loss. To produce an all-weather full-colour image, Hikvision developed a technology based on the human eye, DarkfighterX.
DarkFighterX breaks the limitations of traditional surveillance cameras by providing clear imagining in poor lighting conditions. As a result, DarkfighterX cameras are used for a broad range of applications, including:
- Local authorities for use around towns, parks and buildings
- Government Institutions
- Petrol Stations
- Retail Parks
- Car parks
- Construction Site Security
