• Electronic sensitivity boosting (SENSE UP)
automatically lengthens the CCD exposure time in
dark situations. Accordingly, moving target objects
may cause conspicuous afterimages, blurs and white
spots.
• When electronic sensitivity boosting (SENSE UP) is
enabled, the electronic shutter function will not work.
• When the Day/Night function is set to "AUTO",
electronic sensitivity boosting (SENSE UP) works
only while black and white image is displayed.

Notes on setting electronic iris (EI):
• If the iris views an unusually bright image, it can
cause a smear that cannot be corrected by adjusting
the light entering through the lens. In this case,
arrange the physical angle of lighting in a way that will
prevent on-screen smearing.
• If there is a fluorescent lighting in the camera
location, flickering of the target object may occur.
Changing fluorescent lighting to incandescent
lighting will prevent the flickering.
• When the electronic iris (EI) is activated, the
electronic shutter (SHUTTER) setting cannot be made.
