Day/Night settings
Switch to B/W in night mode
Select this checkbox to enable the Network Camera to automatically switch to Black & White display
during the night mode.
IR cut filter
With a removable IR-cut filter, this Network Camera can automatically remove the filter to let Infrared light
pass into the sensor during low light conditions.
■ Auto mode (The Day/Night Exposure Profile will not be available if Auto mode is selected)
The Network Camera automatically removes the filter by judging the level of ambient light.
■ 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.
