SETTINGS
NR MODE
Select to set the 2D NR filter mode (Y, C, Y/C).
Y LEVEL
(0-15) Indicates the noise reduction strength for the luminance signal. Higher value
performs stronger noise reduction and makes the image less sharp. Due to the
limitation of 2D NR, noise reduction may not be effective enough.
C LEVEL
(0-15) Indicates the noise reduction strength for the chrominance signal. Higher
value performs stronger noise reduction and makes the image less sharp. Due to the
limitation of 2D NR, noise reduction may not be effective enough.
5.1.7. DAY/NIGHT submenu
Menu allows to set operating mode of the electronic D/N function. There are 5 modes which can
be chosen.
COLOR
The Day/Night function is set to OFF.
B/W
The NIGHT mode is established forcibly, and chroma is set to OFF. When B/W<
┘
is
selected, click ENTER to bring up the B/W sub-menu for further settings.
BURST (ON/OFF) Sets whether to output the burst signal when the Night status has
been identified.
IR OPTIMIZER (ON/OFF) Automatically balances the infrared light required in a
scene
MODE (AUTO/CENTER) Features to center of image or automatic area.
LEVEL (0-31) Defines level of the optimization
AUTO
Day or Night is automatically identified and controlled accordingly. After pressing SET
button in this mode submenu depicted below appears.
BURST (ON/OFF) Sets whether to output the burst signal when the Night status has
been identified.
DELAY CNT (0-255) Is the time in seconds before Day
↔
Night switches. DELAY can
avoid the unwanted/frivolous switching of short term lights such as light from a passing
car.
DAY
→
NIGHT (0-255) Select to set the threshold for identifying the Night status from
the Day status. Lower (Higher) value makes the camera switched from Day to Night at
lower (higher) illumination. If the camera stays in Color at night time, increase
DAY
→
NIGHT threshold value until it just switches to Night.
NIGHT
→
DAY (0-255) Select to set the threshold for identifying the Day status from
the Night status. Lower (Higher) value makes the camera switched from Night to Day
at lower (higher) illumination. If the camera stays in B/W mode during day time,
decrease NIGHT
→
DAY threshold value until it switches to Day.
EXT1
In this mode way of D&N change is controlled by external synchronization
(photovaristor). EXT1 mean D&N will exchange at high level voltage,
EXT2
In this mode way of D&N change is controlled by external synchronization
(photovaristor). EXT2 mean D&N will exchange at low level voltage,
