3.1 VIDEO FORMAT
You can select the video format as 2 MP @ 25 fps or 2
MP @ 30 fps.
You can also select PAL, or NTSC in CVBS mode.
3.2 EXPOSURE
EXPOSURE MODE
You can set the EXPOSURE MODE to GLOBAL, BLC, HLC,
WDR (supported by Type I camera), DWDR (supported
by Type II camera), or HLS (supported by Type I
camera).
GLOBAL
GLOBAL refers to the normal exposure mode which
adjusts lighting distribution, variations, and
non-standard processing.
BLC (Backlight Compensation)
The BLC (backlight compensation) function can
compensate light to the object in the front to make it
clear, but this causes 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.
Note:
WDR is only supported by Type I camera.
DWDR (Digital Wide Dynamic Range)
Digital wide dynamic range gives the camera the ability
to view dark areas of the given image as well as
extremely lighted portions of the image, or areas of
high contrast.
Note:
DWDR is only supported by Type II camera.
HLS (Highlight Suppression)
It is the same visual effect as the solar eclipse. If the
brightness of a part in the image exceeds the threshold,
this part will become black. Then whole image can be
clear.
Note:
HLS is only supported by Type I camera.
AGC
It optimizes the clarity of the image in poor light
conditions. The AGC level can be set to HIGH, MEDIUM,
or LOW.
Note:
The noise will be amplified when setting the AGC level.
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 to OFF, ×2, ×4,
×8, or ×16 according to the different light conditions.
Note:
SLOW SHUTTER is only supported by Type I camera.
