You can also switch between [Day Mode] and [Night

Mode] using the Day/Night mode function of the

Admin Viewer (p. 153).

Note

• See “Subjects Difficult to Focus On” (p. 40).

• It is recommended that you check the focus after rebooting the

camera.

• Focus ranges (rough guide) are shown in the following table

according to the settings of [Day/Night (when Auto is set)], etc.

* When using an infrared lamp, the camera may be out of focus.

Camera Control

(1) [Digital Zoom]

Set digital zoom to [Disable] or [Enable].

The higher the digital zoom ratio, the lower the image

quality becomes.

(2) [Image Stabilizer]

Select [Disable], [On1] or [On2] for image stabilizer.

The image stabilizer function has the effect of

correcting blurry images caused by movement of the

camera. Try [On2] if the image is still blurry after

selecting [On1].

If you have selected [On1] or [On2] as the image

stabilizer setting, the viewing angle will be smaller and

the image more coarse than when [Disable] is

selected. This is not a malfunction.

(3) [AGC Limit]

Select one of 5 levels from 1 to 5 to automatically set

the upper gain limit. The greater the value, the higher

the sensitivity becomes. If you do not want to use the

automatic gain adjustment, select [OFF]. Setting the

[AGC Limit] allows you to record with reduced noise

when recording in low light conditions.

(4) [Smart Shade Control Strength (Auto)]

Select [Mild], [Medium], or [Strong] for the control

strength when [Smart Shade Control] (p. 55) is set to

[Auto].

• [Mild]: Select this when noise reduction is a priority.

• [Medium]: Recommended setting for auto mode

(factory default setting).

• [Strong]: Select this when visibility in dark areas of

the scene is a priority.

(5) [Haze Compensation Strength (Auto)]

Select [Mild], [Medium], or [Strong] for the haze

compensation strength when [Haze Compensation]

(p. 55) is set to [Auto].

Important

• The initial camera settings (1) to (11) 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. 149).

• 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.

• [Smart Shade Control] cannot be used if [Haze

Compensation] is set to [Auto] or [Manual].

• [Haze Compensation] cannot be used if [Smart Shade

Control] is set to [Auto] or [Manual].

• 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 [Exposure] of the

Admin Viewer to [Auto], [Auto (Flickerless)] or [Auto (Shutter-

priority AE)] (p. 151).

However, when [Auto (Shutter-priority AE)] is being used,

night mode may not be activated even if [Day/Night] is set to

[Auto], depending on the shutter speed.

• The Day/Night Mode can be switched manually via the Day/

Night function of the Admin Viewer (p. 153), or via the

[External Device Input] (p. 70) or [Timer] (p. 71) settings in

[Setting Page] > [Event].

• To use with infrared illumination, set [Day/Night] to [Manual].

• 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.
