In surveillance, WDR, or Wide Dynamic Range, allows a camera to filter the intense back light surrounding a subject and thus enhances the ability to distinguish features and shapes on the subject. WDR cameras are usually recommended for situations where light enters a premise from various angles such as a multi-window room. A camera placed on the inside of the room will be able to see through the intense sunlight or artificial light coming in. If an indoor security camera is pointed towards a window or an entrance door, you will see the background washed out during daytime. This is very common situation in restaurants and stores which have big glass windows.
