Day/Night Settings
Switch to B/W in night mode
Select this to enable the Network Camera to automatically switch to Black/White during night
mode.
Turn on external IR illuminator in night mode
Select this to turn on an external IR illuminator (connected via Digital Output lines) when the
camera detects low light condition and enters the night mode.
IR cut filter
With a removable IR-cut filter, this Network Camera can automatically remove the filter to let IR
light enter the light 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 (1~3)
The Network Camera automatically removes the IR cut filter 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 outdoor housing.
■ 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.
