4.2.12 Day/Night
Day/Night settings apply only to
the NWC-0900 camera.
"Automatic" enables the camera
to switch automatically from
daylight conditions (using the
color sensor) to nighttime con-
ditions (using the monochrome
sensor) and vice versa, based
on the Threshold settings (see
below).
"Day" enables the daylight
mode and disables the night-
time mode.
"Night" enables the nighttime
mode and disables the daylight
mode.
‘Threshold’ adjusts the auto-
matic switching of the camera:
"Switch At" changes the adjust-
ment level of darkness from
daylight to nighttime mode.
"Toggle Guard" changes the
adjustment level of brightness
from nighttime to daylight
mode. Toggle Guard set to 0% corresponds to "Switch At" set
to 100%. Toggle Guard should be adjusted to prevent mode
toggling during the transitional lighting.
4.2.13 Auto-Iris
The Auto-Iris menu allows monitoring the state of the automatic
DC iris. If the scene is too dark, the camera will open the iris
fully. This allows more light onto the sensor and will substan-
tially improve the low-light performance. If the scene is too
dark when the camera is started, the camera will not close the
iris until there is enough illumination.
Camera DC auto-iris can be configured using Auto-Iris menu:
