LENS SETTING
DAY/NIGHT setting
AGC MAX GAIN setting
Use the CURSOR button (j or l) to move
the cursor to AGC MAX GAIN, and then use
the CURSOR button (d or c) to select the
maximum AGC gain.
Available settings: +9dB, +12dB, +15dB
DNR setting
Use the CURSOR button (j or l) to move
the cursor to DNR, and then use the
CURSOR button (d or c) to select the
digital noise reduction setting.
Available settings:
ON: DNR (digital noise reduction) is applied.
This reduces interference at low luminance
levels.
OFF: DNR is not applied.
Note: Digital noise reduction operates when the
gain control increases. In addition,
blurring and ghosting of images can
occur when moving images are being
monitored, and so the resolution is also
reduced slightly.
BURST setting
Sets burst suppression. If other peripheral
devices (such as a multiplexer) are connected to
the system, bursts (distortion of image color)
can occur when switching between color and
black & white. If this happens, change the
BURST setting to "ON".
Use the CURSOR button (j or l) to move
the cursor to BURST, and then use the
CURSOR button (d or c) to select the burst
setting.
Available settings:
ON: The color burst signal is turned on.
OFF: This should normally be set to "OFF".
FOCUS setting
Sets the focus when switching to black & white
mode.
Use the CURSOR button (j or l) to move
the cursor to FOCUS, and then use the
CURSOR button (d or c) to select the focus
setting.
Available settings:
1: Near-infrared wavelength correction is set.
(around 900 nm)
2: Visible light spectrum is set.
Note: This is set to "1" at the time of shipment
from the factory. If the images are out of
focus, change it to "2".
LEVEL setting
Sets the switching level for color mode and
black & white mode. The three available settings
are LOW, MID or HIGH. In addition, the
switching level can be set manually (ADJ; see
p22).
Available settings:
LOW: The mode switches when the luminance
of the objects being monitored is
comparatively dark.
MID: The mode switches when the luminance
of the objects being monitored is between
the LOW and HIGH levels.
HIGH: The mode switches when the luminance
of the objects being monitored is
comparatively bright.
ADJ: The switching level for color mode to
black & white mode and for black & white
mode to color mode respectively can be
set manually.
