Day/Night Settings
IR cut filter
With a removable IR-cut filter, this Network Camera can automatically remove the filter to let IR light into
the sensor during low light conditions�
■ Day mode
In day mode, the Network Camera switches on the IR cut filter at all times to block 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 IR cut filter at all times for the sensor to accept
infrared light, thus helping to improve low light sensitivity�
■ Schedule mode
The Network Camera switches between day mode and night mode based on a specified schedule.
Enter the start and end time for day mode. Note that the time format is [hh:mm] and is expressed in
24-hour clock time� By default, the start and end time of day mode are set to 07:00 and 18:00�
