The surface of the DarkEye lens is coated with multiple layers of anti-reflection coating. As the aspherical lens has a free-form surface, the lens improves light transmittance, and consequently, enhances image brightness at night. The DarkFighter lens employs an aspherical lens shape, which effectively reduces image aberration present in conventional cameras with a spherical lens. Hikvision achieves this by modifying the order of the photosensitive layer and metal layer within the sensor, resulting in decreased light reflection and increased light usage. Single Pixel Area: Conventional Camera (left) vs DarkFighter Camera (right)ĭarkFighter cameras also have a backside illuminated sensor, which improves brightness by 30%. To further enhance low-light performance and improve light passing quantity, the sensor's single-pixel area is nearly double the size of a normal sensor. Hikvision specifically designed their sensor to have an extremely high quality, as well as a high S/N ratio and increased Wide Dynamic Range (WDR). Similarly, if a high-quality sensor is used, the image will be of extremely high quality. If a low-quality sensor is used, a poor image will be produced. In a surveillance camera, the quality of the sensor determines the quality of the captured image, especially in low light conditions. The security of your premises, whether that's your home or business, is of the utmost importance, at both day and night.įortunately, this detrimental problem has been solved by Hikvision's range of ultra low-light cameras with DarkFighter technology. Poor image quality in low light environments is a common and recurring problem many have faced. This problem can be the cause of major concerns, especially as the most crime happens at night.
