What are WDR security cameras used for?

times   2015-04-29

A WDR camera (Wide Dynamic Range) is used for capturing images of objects surrounded by a strong back light, while still keeping the background visible. WDR technology uses special high-speed CCDs to make two consecutive image scans to one picture. Non-WDR cameras just make one pass.

The first scan captures images in the normal light condition. Right after, the camera captures the second image at high speed to capture the images that are in the strong light. The image processor then superimposes the two video images to provide a single picture that can see all areas. 

A typical use for a WDR camera is capturing scenes indoors that have large windows in the background with lots of sunlight. A WDR camera would enable you to capture both the indoor and outdoor/background scene clear.
