Continue to configure the other settings in the Exposure section:
·
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 1/3 rd , Central 1/6 th , Left, Right, or OFF (default setting). The settings
are as follows:
·
Highlight Compensation – This setting masks bright light sources that are directed at the camera.
Select ON or OFF (default setting).
·
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.
Configure the settings in the Day/Night Switch Control section:
·
Mode – The Day/Night switch activates the IR Cut (IRC) filter for electronic day/night operation.
Three modes are available: Auto, Color, and B/W.
·
4K model ONLY - Enhanced Low Light Performance (ELLP) is check ed off by default, but can be
enabled. When camera is set to 4K, ELLP enhances the image and sensitivity. It also k eeps
cameras in color for longer before switching to black and white mode.
Note: ELLP may not be used when the camera is set to record images on an SoE card.
·
Auto – Select Auto for automatic operation according to the ambient light level. The camera
converts from Day (color) mode to Night mode (monochrome/black and white) automatically
at nighttime or in low-light conditions. When there is sufficient light, the camera converts
automatically from Night mode to Day mode. This is the default setting.
·
Color – Select Color for daylight operation. This deactivates IR mode by putting the camera
into Day mode.
