Descriptions
NORMAL – Optimized for the normal indoor and
outdoor in the good lighting condition.
WDR – Improves the visibility for the high bright area
and the dark area by the double captures of image
with LONG and SHORT exposures. With WDR ON,
the frame rate becomes half by the double captures.
WDR level can be selected from LOW, MID and
HIGH. Care should be taken to select this mode
because video may lose its quality in some environ-
ments by the over compensation.
•
CVBS video signal: Connecting 2nd video to
CVBS port disables WDR function temporary. It
should be considered when installer adjusts the
video with installation monitor via CVBS video
signal.
D-WDR – Improves the visibility by compensating
the video gain for the dark area. Noise can increase
in the dark area accordingly.
BLC – Improves the visibility for the dark object by
the bright back light. Outside area of BLC window
can over saturate. BLC has a target window for
compensation and its size and position can be set
by H-POS, V-POS, H-SIZE and V-SIZE.
HLC – Cuts out the highlight area with black mask
and excludes it from compensation.
3D-NR is a very sophisticated and powerful time-
based noise reduction technology by monitoring the
noise for the several video frames and defining and
eliminating them consecutively at low light.
Higher setting reduces noise much more but results
in losing the sharpness and the tail effect or the
motion blur for the fast moving target at low light.
