Day/Night:
■ Auto
The Network Camera automatically switches between day mode and night mode by judging
the level of ambient light. This mode is accessible only when the exposure mode is set to Auto.
■ Day mode
In day mode, the Network Camera switches on the infrared cut filter at all times to block the
infrared light from reaching the sensor so that the colors will not be distorted.
■ Night mode
In night mode, the Network Camera switches off the infrared cut filter to allow the infrared light
to pass through. This improves the sensitivity of the Network Camera in low-light conditions.
■ Schedule mode
The Network Camera switches between day mode and night mode based on specified
schedule. Enter the starting time and ending time for the day
[hh:mm] and is expressed in 24-hour clock time. By default, the starting time and ending time
of day mode are set to 07:00 and 18:00.
