WDR is the abbreviation used for Wide Dynamic
Range. WDR is the technology used on professional security cameras, where there
is need to balance brighter and darker surveillance areas. WDR is actually the
difference in lighting. It is clearly seen, when recording entrance, where
bright outdoor light is merged with dim indoor light, or when the area has
large glass windows. Cameras using Wide Dynamic Range technology are able to
record clearer details in low light scene, while making sure that the
highlights don't get blown-out, and as a result having natural looking shot.
WDR technology is commonly used in surveillance
cameras and in some medical applications. In an area with extremely bright and
dark parts or in back light situations when the light comes from the back of a
person, standing in front of a big window, a camera without WDR would produce
an image where objects in the dark areas are hardly visible. Wide dynamic range
solves this issue by applying techniques such as using different exposures for
different objects in a scene for making objects in both bright and dark areas more
visible and clearer.
