AGC : It’s a form of amplification where the camera will
automatically boost the image output signal to optimize the
clarity of image in poor light conditions. You can set the AGC
value from 0 to 15. The AGC is disabled if the value is set to 0.
Note:
The noise will be amplified if the AGC is on.
SENS-UP : Sense up increases the exposure on a signal frame,
which makes a camera more sensitive to light so it can produce
images even in low lux conditions. You can set the SENS-UP as
OFF or AUTO according to different light conditions.
OFF : SENS-UP function is disabled.
AUTO : The SENS-UP function will atomically adjust itself to x2, x4,
x6, x8, x10, x15, x20, x25, and x30 according to the different light
conditions.
BRIGHTNESS : Brightness refers to the brightness of the image.
You can set the brightness value from 1 to 100 to darken or
brighten the image. The higher the value, the brighter the image
is.
D-WDR : The digital wide dynamic range helps the camera
provide clear images even under backlight circumstances. When
there are both very bright and very dark areas simultaneously in
the field of view, D-WDR balances the brightness level of the
whole image and provide clear images with details.
Set the D-WDR as ON to improve the image quality under the
backlight environment.
Set the D-WDR as OFF to disable the function.
