Canon VB-H43 Operation Manual page 58

You can also switch between [Day Mode] and [Night
Mode] using the Day/Night mode function of the
Admin Viewer (p. 155).
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. 151).
• 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. 153).
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. 155), or via the
[External Device Input] (p. 72) or [Timer] (p. 73) 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.
Note
• See "Subjects Difficult to Focus On" (p. 42).
• 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.

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. 57) 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. 57) is set to [Auto].
