What is the WDR function of IP Cameras?
Dynamic Range is the difference in light levels in an image, between the darkest and the brightest areas.
Cameras with wide dynamic range (WDR) technology can enable the camera to capture details clearly in both the poorly and strongly illuminated areas of the video.
