IR cut lter
With a removable IR-cut lter, this Network Camera can automatically remove the lter to let IR
light enter the light sensor during low light conditions.
■ Day mode
In day mode, the Network Camera switches on the IR cut lter 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 lter 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 lter when a Digital Input is triggerred.
For example, the digital input can come from a housing that is equipped with IR illumination and
control circuits such as VIVOTEK’s AM-214.
■ 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.
Note that the IP9172-LPC is installed in a housing aided by an external IR. The
Day/Night mode control should always be enabled by a digital input connection with
the external IR illuminator.
