Note
If you set the shift to night mode to occur when it’s brighter, the image remains sharper as there will be less low-light
noise. If you set the shift to occur when it’s darker, the image colors are maintained for longer, but there will be more
image blur due to low-light noise.

Set the max gain to a lower value.

If you maximize the details in an image, the bitrate will probably increase and you might get a reduced frame rate.
•
Set the compression as low as possible.
•
Select MJPEG streaming.

Turn off Zipstream functionality.
Handle scenes with strong backlight
Dynamic range is the difference in light levels in an image. In some cases the difference between the darkest and the brightest
areas can be significant. The result is often an image where either the dark or the bright areas are visible. Wide dynamic range
(WDR) makes both dark and bright areas of the image visible.
