Important
• The initial camera settings

to
5
define the defaults that
apply when the camera is started. Setting changes will be
reflected only after the camera is reconnected or rebooted.
Specify the settings used in the actual operating environment
from the Admin Viewer (P. 7-10).
• If the subject is a traffic signal or electronic scoreboard, etc.,
the captured image may flicker.
In this case, try changing the [AE mode] setting to [Auto
(Shutter-priority AE)] and selecting a shutter speed lower
than 1/100 to see if the problem improves.
Important
• If [Auto] is selected for [Day/Night], conduct a thorough
operation test to check the effectiveness of the setting
beforehand.
• If [Auto] is selected for [Day/Night], set [AE Mode] and the
Admin Viewer to [Auto], [Auto (Flickerless)] or [Auto (Shutter-
priority AE)] (P. 7-12).
• To use with infrared illumination, set [Day/Night] to [Manual].
Infrared illumination cannot be used with [Auto].
• When [Day Mode] and [Night Mode] are switched, the image
may not focus correctly depending on the brightness.
• If [Day/Night] is set to [Auto], the infrared cutoff filter may
move several times while the mode is switching between
[Day Mode] and [Night Mode]. Pan, tilt, zoom and manual
focus will not work during this period.
