How exactly does WDR (Wide Dynamic Range) effect cameras?
Wide Dynamic Range is a technology utilized by security cameras in order to balance out images that have a large dynamic range. An example of this situation would be if an indoor security camera were pointing towards a window or building entrance. During daytime, the image produced by the camera would be extremely washed out due to the high brightness of the incoming light. This effect is commonly seen in restaurants, stores, offices, and other buildings that have large windows or entrances. In order to solve this problem, CCTVs have been using Back Light Compensation (BLC) to help compensate for high brightness situations. However, Wide Dynamic Range technology has recently become the most popular solution to washed out images. WDR cameras are fitted with two Charge-Coupled Devices (CCD), one high speed, and the other low speed which are designed to take multiple scans of the same image in order to provide a clear and balanced image. The two CCDs take 2 scans of the same image instead
