If I select a WDR preset and change the AGC value, when I
go back to the WDR preset, it has changed to “Custom”.
Has my preset been changed or erased?
The WDR presets set the dynamic range, the exposure,
sharpness and the AGC level. Changing any of these will
change the WDR preset to Custom. When you saw the Custom
setting, the preset that you selected was still loaded, except
that the AGC had changed, thus customizing your setup. This
camera function allows any WDR preset to be loaded into
custom so that you can modify the dynamic range and
exposure of the underlying preset.
There are seven WDR presets in the camera. How do I
know which one to use for my scene?
The WDR presets consist of three main types—center-
weighted scene, full scene, and full scene with spot glare.
Depending on the scene, you can narrow down your choice to
the presets within each of these groups. Most applications can
use the full scene WDR preset—INDOOR or OUTDOOR—as
these are optimized for general lighting conditions (General
Scenes in the first generation HCCWD484 wide dynamic
camera).
Other applications in which the area of interest is primarily in
the center of the scene should use the ATM, LOADING DOCK
or LOBBY WDR presets.
•
ATM is optimized to render proper exposure of faces
when the person is backlit by the sun, while still allowing
the ability to make out a person standing behind the
person using the ATM machine.
•
LOADING DOCK is for areas with a tall vertical opening
and walls on either side.
•
LOBBY is for areas with large windows across the scene.
However, depending on your lighting conditions and angle of
view, a different preset may render a better picture for your
scene.
For scenes in which there are hot spots of illumination that can
occur anywhere in the scene and you need to see detail of
objects near these hotspots, the Full scene with spot glare
presets—GAMING and LICENSE PLATE—will likely offer the
best picture quality for seeing the objects of interest.
•
GAMING is optimized to allow the reading of cards when
the card is in a hotspot and is producing glare.
•
LICENSE PLATE is optimized to allow the viewing of the
front license plate when the headlights are shining into
the camera.
