Manual:
Note that WDR and Defog functions will be disabled using the Manual mode setting.
NOTE:
When Iris Priority is selected for the Exposure mode, the tunable aperture size is related to zoom
ratio. When using different zoom ratios, the range of aperture sizes can be different. When zoom ratio is
0x, the range of iris sizes is F1.6~F14. When zoom ratio is 20x, the iris size is F3.4.
■ WDR Pro (Wide Dynamic Range): Default is on. When set to Auto, you can select the strength of the
WDR function. The Low, Medium, High options correspond to the level of contrast between the overly-
lit area and the shaded areas. For example, the High option applies to a high contrast scenario. Note
that when the exposure time is set to longer than 1/60 second, the WDR function will be disabled.
IMPORTANT:
1. Because the exposure settings are also available in the Profile setting, incorrect configurations such
as a very high exposure level will let the camera consider it is operating in the Day mode even when
the ambient light is actually low. The camera will falsely remove the IR cut filter, and thus results in
distorted image colors.
Therefore, when the IR cut filter is in the Auto mode, the Profile setting is not available.
2. When set to the Night mode, the image display automatically changes to Black and White.
3. There is no Preview button in the Exposure window. Configuration changes are directly reflected in the
live view window.
