Acronym for Wide Dynamic Range. This refers to cameras. This is a high-end feature. A camera viewing an image with very bright and very dark sections will probably not show any detail in the dark areas as the camera is adjusted to tone down the bright areas. With WDR the camera view will be much improved showing detail in both light and dark areas. This feature also provides better image detail in low light conditions.
WDR (Wide Dynamic Range) enables a camera to capture details in both bright and dark areas of a scene. It’s essential for surveillance in environments with high contrast lighting.
