What is Wide Dynamic Range

Wide Dynamic Range is a technology employed by cameras in order to provide a clear picture in situations where there is a large dynamic range in lighting. This typically occurs when a camera is pointed towards a large window or entrance that lets in large amounts of light. For cameras not implementing WDR (Wide Dynamic Range) technology the images that the camera records will be washed out and hard-to-see.

These hard to see images are produced because of the large dynamic range from the dark and bright elements of the room which the camera has trouble processing. WDR cameras implement two Charge-Coupled Devices and take two scans of the same image and process them together to provide clear images.
