Tips:
If there is an object in close proximity, the IR lights
reflected back from it can mislead the Smart IR's
calculation of light level. To solve this problem, you
can place an "Exposure Exclude" window on an
unavoidable object in the Exposure setting window.
See page 62 for how to do it.
You can also configure the "Exposure Exclude"
window in a night mode "Profile" setting so that your
day time setting is not affected.

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.
■ Schedule mode
The Network Camera switches between day mode and night mode based on a specified
schedule. Enter the start and end time for the 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.
