Day/Night Settings
■ Turn on external IR illuminator in night mode
The camera’s digital output signal can be connected to external IR lights to turn it on when the camera
detects low light conditions and enters the night mode.
IR cut lter
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 lter by judging the level of ambient light.
■ 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.
■ Schedule mode
The Network Camera switches between day mode and night mode based on a specied 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.
IMPORTANT:
1. Because the exposure settings are also available in the Prole setting, incorrect congurations such
as a very high exposure level will let the camera consider it is operating in the Day mode even when
the ambient light is actually low. The camera will falsely remove the IR cut lter, and thus results in
distorted image colors.
Therefore, when the IR cut lter is in the Auto mode, the Prole setting is not available.
2. When set to the Night mode, the image display automatically changes to Black and White.
3. There is no Preview button in the Exposure window. Conguration changes are directly reected in the
live view window.
