Hikvision WDR technology works by capturing multiple images of a scene at different exposure levels and then combining them into a single, balanced image with details visible in both bright and dark areas.
When a Hikvision WDR camera captures a scene, it first takes one image at a normal exposure level, which captures detail in the mid-range of brightness. It then takes a second image at a higher exposure level, which captures details in the brighter areas of the scene, such as a window or a light source. Finally, it takes a third image at a lower exposure level, which captures details in the darker areas of the scene, such as a shadow or a dimly lit corner.
The camera's software then combines the three images into a single image, using advanced algorithms to select the best parts of each image and create a final image with balanced brightness and detail visible in both bright and dark areas. This process allows Hikvision WDR cameras to capture clear, high-quality video in challenging lighting conditions, such as in areas with bright sunlight or strong backlighting.
Hikvision WDR technology can be particularly useful in scenarios such as entrances, exits, or parking lots, where bright sunlight or artificial lighting can cause significant glare or shadowing, making it difficult to capture clear video.
