Does your Video Security have Wide dynamic range

Conventional camera without wide dynamic range

Camera with wide dynamic range applied

Wide dynamic range is a feature in some Axis network cameras that handles a wide range of lighting conditions in a scene. In a scene with extremely bright and dark areas or in backlight situations where a person is in front of a bright window, a typical camera would produce an image where objects in the dark areas would hardly be visible.

WDR solves this by applying various techniques to enable objects in both bright and dark areas to be visible.

WDR – Forensic Capture

Axis’ WDR – Forensic Capture optimizes video for forensic purposes by enabling an extremely high level of detail to be visible in both dark and bright areas of a scene. It is the result of years of development at Axis combined with the best imaging components on the market. An Axis camera with WDR – Forensic Capture applies advanced algorithms to optimize image quality and includes the ability to seamlessly transition between WDR and low-light mode.

WDR – Dynamic Contrast

With Axis’ WDR – Dynamic Contrast, the camera performs an advanced tone mapping, where some brightness levels are dropped to decrease the bit depth to a format that a computer screen can handle. In this tone mapping, both the darkest and the brightest parts are taken into account, resulting in more details on both ends.

WDR – Dynamic Capture

Axis’ WDR – Dynamic Capture works by acquiring several images with different exposure times for each image. These pictures are then combined in a composite, where both the brightest and the darkest parts are kept, resulting in an image with exceptional clarity and sharpness.
