Hikvision Technologies

Acusense – AcuSense is a technology designed for Hikvision cameras, that uses deep-learning AI algorithms to improve security capabilities.
This allows for AcuSense equipped cameras to achieve impressive Human and Vehicle classification, meaning that it will recognise whether an alarm was triggered by a person, vehicle, or other object. This reduces the amount of false alarms, and allows your surveillance system to prioritise genuine security risks.

Darkfighter – DarkFighter is a technology that helps to improve a camera’s low light performance, allowing image quality to remain clear regardless of the amount of light in a scene. This keeps video surveillance working effectively at all times.

Image Enhancement Capabilities

IR Illumination – Suppliment Light, with an IR wavelength of 850nm, and a range of up to 90m.

120dB Wide Dynamic Range (WDR) – Improves image visibility in challenging lighting conditions.

Highlight Compensation (HLC) and Backlight Compensation (BLC) – Compensates for areas of darkness and bright light in the camera’s field of view, keeping images clear and balanced.

3D Noise Reduction (3DNR) – Reduces image quality interference from incoming ‘noise’ keeping footage as clear as possible.
