What is a WDR (Wide Dynamic Range) Camera?
If an indoor security camera is pointed towards a window or an entrance area, you will see the background washed out during daytime. This is a very common situation in restaurants and stores which have large glass windows. To fix this problem, CCTV manufacturers introduced WDR (Wide Dynamic Range) technology. The camera is fitted with two CCDs, one high speed CCD and one low speed. The two CCDs take 2 scans of the same image instead of one scan like a typical camera. The first CCD scans the images in normal light condition. After that, the camera scans the second time at high speed to get the image with strong light background. The image processor then combines the two images into one to provide a balanced image which shows the indoors and outdoors clearly. (Source: http://en.wikipedia.org/wiki/Wide_dynamic_range)
