WDR (Wide Dynamic Range) combines the spaces of bright lights with the spaces of shadows that are in the same shot, to create a balance in the final image. This is possible by doing full exposure metering (highlights, tones, colors, depth of field, objects, etc.) and adding light detail on the gloomiest surfaces, and subtracting luminescence from the brightest areas. Such modification can improve up to 800% of the image quality compared to that of a camera without WDR.

What Is the Function of the WDR?

Wide Dynamic Range (WDR) refers to the ratio between the largest and smallest measurable amounts of something. 

In the case of video surveillance, the dynamic range measures the relationship between the elements that are lighter or with greater illumination and darker or less incidence of illumination in the image. 

WDR technology is excellent for high-contrast scenes, balancing brightness and shadow areas simultaneously so the image doesn’t appear washed out or too dark.
