Parameter Description
3. Exposure Settings
Iris Mode Only “Manual” is available.
Exposure Time The exposure time controls the length of time that the aperture is open
to let light into the camera through the lens.
Select a higher value if the image is dark and a lower value to see a
fast moving object.
Gain Select a value to adjust the image brightness.
Day/Night Switch
This option appears when the Common option is selected.
Day/Night Switch Defines whether the camera is in day or night mode. The day (color)
option could be used, for example, if the camera is located indoors
where light levels are always good.
There are five options:
Auto: The camera automatically detects which mode to use;
Day: The camera is always in day mode;
Night: The camera is always in night mode;
Schedule: The camera switches according to the defined schedule.
Triggered By Alarm Input: The camera switches when the alarm
input is triggered.
Note: “Triggered By Alarm Input” is supported when the camera
supports “Alarm I/O” on harness.
Sensitivity If “Auto” is selected as the Day/Night switch, you can choose the
sensitivity value from 0 to 7. The higher the value, the easier it is for
the mode to switch. Default is 4.
Delay Time This is only available when “Auto” is selected as the D/N switch mode.
The filtering time refers to the interval time between switch over from
day/night. You can set it between 5 and 120 s.
Smart IR When enabled, over exposure issues can be avoided.
