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.
■ Auto mode
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.
■ Synchronize with digital input
The Network Camera automatically removes the IR cut filter when DI triggers. Some external
housing may come with its light sensor and IR lights, and has a pin signal to tell the camera to
switch off its IR cut filter.
■ 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.
Light sensor sensitivity
Select Low, Normal, or High sensitivity for the light sensor.
