Image Sensor Options
• Video Style: Select TV Color or PC Color.
• Backlight Compensation: Enable/disable
Backlight Compensation. If enabled, objects are
exposed brighter in backlit situations.
• Sharpness: Adjust the sharpness level. Adjust
the contours to make the images look sharper.
Increasing the value raises the sharpness level, but
using too high a value can result in unwanted noise.
• Noise Filter: Select the noise filter level. Noise filter
can reduce the noise in images taken under low-
lighting conditions. Increasing the value reduces the
noise, but using too high a value can result in blurry
images.
• 3DNR : Enable/disable 3DNR (3D Noise Removal).
3DNR reduces background noise in images taken
under low-lighting conditions. 3DNR does not
produce blurry images like Noise Filter but can result
in ghosting.
• IR Mode: IR Mode blocks out the infrared
spectrum. You can ensure clear images at all times
by blocking out the infrared spectrum in high-lighting
conditions and allowing the infrared spectrum to
pass through in low-lighting conditions.
– Daytime Mode/Nighttime Mode: Enable/
disable
IR Mode.
– Auto: Allow the system to enable/disable IR
Mode automatically.
• Black & White Mode: Display the images
in greyscale for greater clarity in low-lighting
conditions.
– On/Off: Enable/disable Black & White Mode.
– Auto: Allow the system to enable/disable Black &
White Mode automatically.
• Smart IR: Adjust the IR LED's brightness level.
Select On to allow the system to adjust the
brightness level automatically. Deselect On to select
a brightness level manually between 0% (darkest)
and 100% (brightest).
• Setup Mode: Select desired setup mode between
Normal and Number-Identification. In Number-
Identification mode, when a certain area of images
is too bright due to backlight under low lighting
conditions and it causes the other area to be too
dark, this function provides the other area of images
brightly and clearly by blocking the backlight in
the certain area. Dark parking lot entrances and
gas station entrances at night, for example (Local
Exposure compensates for the bright light coming
from incoming vehicle headlights and makes it
possible to see the license plates). When setting to
the
Number-Identification mode, some option
settings will be adjusted automatically, and you
cannot change them as long as the Setup Mode is
not changed.
• Mirror: Select Horizontal or Vertical to flip the
image horizontally and/or vertically.
Select Apply after setting up a camera to see
images from the concerned camera on the left side
of the screen. Selecting
Apply or OK displays a
popup screen that indicates whether the camera has
been set up successfully or not.
