Tips:
If there is an object in close proximity, the IR
lights reflected back from it can mislead the Anti-
overexposure'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 79 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.
