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.
