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 75 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.
