Exposure Value – This is a number that represents a combination of a camera's shutter speed and
f-number, which brightens or darkens the scene accordingly. Select from the following options: -2,
-5/3, -4/3, -1, -2/3, -1/3, 0, 1/3, 2/3, 1, 4/3, 5/3, or 2 . The higher the number, the brighter the image.
The default setting is 0 .
·
Back light Compensation – In images where a bright light source is behind the subject of interest,
the subject would normally appear in silhouette. The backlight function of the camera allows it to
adjust the exposure of the entire image to properly expose the subject in the foreground. From the
drop-down list, select one of the following options for the backlight compensation:
OFF, Upper
2/3rd, Lower 2/3rd, Central 1/3rd, Central 1/6th, Left, Right, or OFF (default setting). The settings
are as follows:

·
Digital WDR – This function improves the image quality and amount of details in high contrast
scenes. Such scenes combine areas with different lighting conditions, where some areas are very
bright and others are dark. If this function was not used, the image either would be overexposed or
too bright in bright areas and completely dark in dark areas. Digital WDR helps to improve image
quality by producing a larger amount of details in both the dark and bright areas of the image.
Select High, Medium, Low, or OFF . When High is selected, the image has the highest wide
dynamic range, so that the IP camera can capture the greatest scale of brightness. Selecting OFF
disables this function. The default setting is Medium .
