WDR (Wide Dynamic Range) - a function that provides high-quality images in uneven lighting conditions.

WDR offers better functionality compared to BLC (Backlight Compensation). WDR uses image exposure analysis. This means that dark objects in the image are brightened, while objects that are too bright are darkened. This function makes all objects visible even in high contrast situations. WDR cameras deliver high-quality images regardless of whether the camera is used indoors or outdoors. A WDR camera can be used in areas exposed to direct sunlight without affecting image quality.

For comparison, what it looks like in practice - below is an example using different modes: on the left - without BLC and WDR, in the center - with BLC, on the right - with WDR.



WDR technology also includes a related function called D-WDR (Digital Wide Dynamic Range).

D-WDR (Digital Wide Dynamic Range) - automatic application of WDR based on software analysis using gamma correction to easily identify objects in dark areas of the image.

D-WDR technology is often misunderstood as WDR. D-WDR is a less expensive and less effective version of WDR. D-WDR better addresses issues with unfavorable lighting conditions; however, the digital version does not provide the high-quality images offered by WDR. The quality of recorded images is acceptable.
