Acusense

Empowered by deep learning algorithms, Hikvision AcuSense technology brings human or vehicle target classification
alarms to front- and back-end devices. The system can greatly reduce false alarms generated by targets other than
humans or vehicles, vastly improving alarm efficiency and effectiveness.

Interms of quality, the Acusense cameras perform exactly the same as Darkfighter Cameras - the only difference is that the Acusense cameras understand what Humans and Cars look like, this reduces false alarms by a large factor. Rain, animals and glare don't activate the alarm and you can sleep peacefully knowing that your camera isn't flooding your phone with false notifications.

Darkfighter

Hikvision Darkfighter cameras are an industry-leading solution for ultra-low light technology. Typically able to to provide full colour images up to 0.002 lux, and black and white up to 0.0002, Hikvision Darkfighter cameras are great for any low-light scenario.

Most security incidents happen at night. Of all known crimes, 70% happen under the cover of darkness. Information about suspects — such as facial features, height, and clothing — and vehicles — license plate number, color, type — are all crucial forensic evidence. In low-light environments, however, these critical details can be easily missed by conventional cameras. Infrared does improve image sharpness on conventional cameras, but it cannot provide color reproduction.

Lux refers to the unit of illuminance, and illumination at night is usually less than five lux. In general, less light means poorer image quality. Manufacturers have used various methods – increased gain, slow shutter, larger sensors or better lenses – to improve image quality in low lux scenes. Hikvision, on the other hand, believes in improving the quality of the components in their cameras instead of using other compensation techniques. For this reason, Hikvision DarkFighter Series cameras combine a larger sensor, a better lens design, along with multiple advanced technologies to provide excellent all-around daytime images, as well as high-quality color images in dark environments. This paper is an introduction to Hikvision’s DarkFighter technology

The image sensor is the core component of a camera. The sensor quality determines the image quality, especially in a low-illumination environment. Hikvision DarkFighter Series cameras use specifically designed, nearly ½-inch sensors, yielding better photosensitivity, a high S/N ratio, and increased wide dynamic range. Their single pixel area is almost twice as large as that of a normal sensor and greatly improves the light passing quantity, which is an essential component in better low light performance.

ColorVu

Hikvision has been leading the security industry in imaging for years. That tradition continues with their powerful new Hikvision ColorVu Technology. ColorVu Technology enables cameras to produce colorful videos even in extremely dimly lit environments. Watch the video below to see how color helps to tell the true stories.

Hikvision ColorVu Cameras’ powerful ability to capture details in low lighting comes from two specific breakthroughs in hardware technologies: advanced lenses and high-performance sensors. Coupled with a supplemental light for extremely dark scenarios, ColorVu cameras guarantee video with colorful details when you need them.

As a result, Hikvision ColorVu Cameras provide bright color video images 24/7 in low illumination conditions. They excel at capturing vivid chromatic images in a multitude of application scenarios, such as public places with no lighting, night security at industrial parks, traffic intersections in low light environments, and many more – everywhere color information is particularly important

Conclusion

Choosing between Color Vu and Darkfighter is all down to the range, we would recommend Colorvu for for most applications under 20M Range and anything over that we would recommend the Darkfighter Cameras - We hope that reading this article helped you narrow down your decision and showed you the features of both systems and how they work.
