Auto
: If you set Exposure mode as
Auto
, the Exposure time and Gain control will not be
configurable since the sensor library will automatically adjust the value according to the ambient
light. Then you can configure iris mode as “indoor” or “outdoor” to reach the best image quality.
■
Iris mode
: Select Indoor or Outdoor iris mode to adapt to the installation. The preset iris aperture
setting will apply. Note that on a fixed lens model, this option is not configurable.
■
AE Speed Adjustment:
This function applies when you need to monitor fast changing lighting conditions. For example,
the camera may need to monitor a highway lane or entrance of a parking area at night where
cars passing by with their lights on can bring fast changes in light levels. The same applies if
the camera is installed on a vehicle, and when it needs to adapts to fast changes of light when
entering and leaving a tunnel.
■
WDR:
This refers to the Wide Dynamic Range function that enables the camera to capture
details in a high contrast environment. Use the checkbox to enable the function, and
use the slide bar to select the strength of the WDR Pro functionality, depending on the
lighting condition at the installation site. You can select a higher effect when the contrast
is high (between the shaded area and the light behind the objects).
