IR cut lter
With a removable IR-cut lter, this Network Camera can automatically remove the lter to let Infrared light
pass into the sensor during low light conditions.
■ Auto mode (The Day/Night Exposure Prole will not be available if Auto mode is selected)
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.
■ Synchronize with digital input
The Network Camera automatically removes the IR cut lter when DI triggers.
