What does the acronym WDR stand for in the context of video surveillance?

Wide Dynamic Range, abbreviated as WDR, refers to a technology used in video surveillance systems to enhance the quality of images captured in challenging lighting conditions. This feature is particularly important in environments where there are significant contrasts between light and dark areas, such as when a scene is backlit or when there are shadows.

Cameras equipped with WDR can capture details in both the bright and dark areas of a scene, allowing for a more comprehensive view of the environment. This is achieved through various techniques, such as blending multiple exposures of the same scene to ensure that neither highlights nor shadows are overly exposed or underexposed.

Understanding WDR is essential for surveillance operators and technicians, as it directly impacts the effectiveness of video surveillance in real-world scenarios where varying light conditions can compromise image quality.
