4.2.12Day/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.

4.2.13Auto-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:
