WDR (Wide Dynamic Range):

This function allows users to identify more image details in an environment

with dark objects posed against an extremely bright background. You may enable the function by selecting

Auto or the Manual mode, and then adjust the sensitivity and correction level (low, medium, high) to

acquire the best image quality.

This camera supports Double exposure in the WDR mode. Double exposure is an advanced rmware

algorithm that delivers best image quality by comparing two video frames taken with different shutter

speeds, e.g., 1/60s and 1/4500s, and rendering data points from them into a well-balanced image.

Note that if this feature is enabled, the camera's video frame rate will be halved, e.g., from 60fps to

30fps. With frames taken at two different shutter speeds, the Long exposure is always set at 1/60s,

while the Short exposure value is user-congurable depending on the lighting condition of where the

camera is deployed.

When completed with the settings on this page, click Save to enable the setting.
