3.1 FORMAT
You can set the video format to 2MP@25fps or
2MP@30fps.
3.2 EXPOSURE
EXPOSURE MODE
You can set the EXPOSURE MODE to GLOBAL, BLC, HLC,
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.
HLC (Highlight Compensation)
HLC stands for highlight compensation. The camera
detects the strong spots (the over-exposure portion of
image), then reduce the brightness of the strong spots
to improve the overall images.
WDR (Wide Dynamic Range)
The wide dynamic range (WDR) function helps the
camera provide clear images even under back light
circumstances. When there are both very bright and
very dark areas simultaneously in the field of view, WDR
balances the brightness level of the whole image and
provide 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.
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 function as OFF, x2, x4,
x6, x8, x10, x12, x14, or x16 according to the different
light conditions.
Note:
This function is not available, when adopts power over
coaxial to supply power.
3.3 DAY/NIGHT
COLOR, B&W (Black White), and AUTO are selectable
for DAY and NIGHT switches.
COLOR
The image is colorful in day mode all the time.
B&W
The image is black and white all the time, and it is
better to turn the IR LIGHT on in poor light conditions.
