[Average]

The entire screen is metered by averaging.

A stable exposure can be achieved even in a

capture environment where there are notable

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

brightness/darkness on the periphery of the screen.

Use this mode if you want to adjust the exposure to

the center of the screen because the subject is

receiving a spotlight or backlight, etc.

[Auto] is selected.

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. 137).

• 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.
