Day/Night
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.
Turn on external IR illuminator in night mode
If your camera is installed with an IR illuminator and the digital output signals are connected to it, you can
let system firmware turn on the supplementary illuminator during low-light conditions.
Turn on built-in IR illuminator in night mode
This option is enabled by default. This camera comes with IR lights under the top panel. When the
onboard sensor detects a low-light condition, the onboard IRs will turn on.
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.
■ Synchronize with digital input
The Network Camera automatically removes the IR cut filter when a digital input is triggered, for
example, when the camera is accompanied by an external IR light that comes with its own sensor and
provides a signal to the camera. Some camera housings come with such mechanism.
■ 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 a day mode are set to 07:00 and 18:00.
