Day/Night
Day/Night ( Figure 23 ) settings apply only to MP3-DN camera including:
Figure 23. Day/Night setting menu
Auto-Iris
The Auto-Iris menu allows you to monitor 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 substantially 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.
Automatic enables the camera to
automatically switch from daylight
conditions (using the color sensor) to
nighttime conditions (using the
monochrome sensor), and back based on
the Threshold settings.
Day enables the daylight mode and
disables the nighttime mode.
Night enables the nighttime mode and
disables the daylight mode.
Threshold adjusts the automatic
switching of the camera:
• Switch At adjusts the level of
darkness to switch from daylight to
nighttime mode.
• Toggle Guard adjusts the level of
brightness to switch 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.
