Description
A flashing background
environment influences image
quality. To obtain high-resolution
images, you can set the
background frequency to suit
lighting conditions. Select a proper
background frequency based on
the standard frequency of the state
grid.
NOTE
Disable the background frequency in
natural light.
Cameras with the backlight
compensation function can
provide clear images in
environments with backlight
condition.
Image exposure adjustment
includes the adjustment of the
sensibility, brightness, and noise.
Increasing the gain increases the
image brightness, sensitivity, and
noise.
When a slower shutter speed is
selected, a longer time passes from
the moment the shutter opens till
the moment it closes. More time is
available for movement in the
subject to be recorded by the
camera.
This parameter is available only
when Exposure mode is set to
Automatic exposure.
NOTE
When the WDR is enabled or
Day/Night mode is set to Color, the
slow shutter is unavailable.
