brightness differences within the screen.
Use this mode to stabilize the exposure in locations
where vehicles or people are moving.
[Spot]
The center of the screen is metered.
An appropriate exposure can be achieved for the
subject at the center of the screen regardless of the

receiving a spotlight or backlight, etc.

Note
• See “Subjects Difficult to Focus On” (p. 38).
• Focus ranges (rough guide) are shown in the following table
according to the settings of [Day/Night] (p. 53), etc.
* When using an infrared lamp, the camera may be out of focus.
Important
• The initial camera settings (1) to (6) 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. 135).
• 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.
• Setting a slow shutter speed may make it impossible for
intelligent functions to work correctly. Select a shutter speed
that suits the capture conditions and purpose.
• In conditions where an outdoor scene is captured
from an indoor location through a glass window, the camera
may focus on the glass surface if there is dust or water there.
Install the camera at the shortest possible distance from the
glass surface.
