EXPOSURE MODE
You can set the EXPOSURE MODE to GLOBAL, BLC, or
WDR.
GLOBAL
GLOBAL refers to the normal exposure mode which
adjusts lighting distribution, variations, and
non-standard processing.
BLC (Backlight Compensation)
BLC (Backlight Compensation) compensates light to the
object in the front to make it clear, but this may cause
the over-exposure of the background where the light is
strong.
WDR (Wide Dynamic Range)
The wide dynamic range helps the camera provide clear
images even under backlight circumstances. WDR
balances the brightness level of the whole image and
provides clear images with details.
AGC (Auto Gain Control)
It optimizes the clarity of the image in poor light
conditions. The AGC level can be set as HIGH, MEDIUM,
or LOW. Select OFF to disable the AGC function.
Note:
The noise will be amplified when the AGC is on.
SLOW SHUTTER
SLOW SHUTTER increases the exposure time on a single
frame, which makes a camera more sensitive to the
light so it can produce images even in low lux
conditions.
You can set the SLOW SHUTTER according to the
different light conditions.
3.3 VIDEO SETTINGS
