Canon VB-H43 Operation Manual page 55

• 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.
• 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. 146).
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.
• When Day/Night Mode is set to [Manual], in addition to the
Day/Night function of the Admin Viewer (p. 148), it is also
possible to switch Day/Night Mode via settings in [Setting
Page] > [Event] > [External Device Input] (p. 68) or [Event] >
[Timer] (p. 69).
• 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. 38).
• 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] Setting Initial Camera Settings and External Device Name
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. 54) 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) [Pan/Tilt Speed Control]
Select [Control at set speed] or [Control by zoom
position] for the pan/tilt operating speed. When
[Control by zoom position] is selected, the pan/tilt
speed is slowest at maximum telephoto, and fastest at
maximum wide angle.
Important
• [AGC Limit] is disabled when [Exposure] is set to [Manual] or
[Auto (Flickerless)] in the Admin Viewer.
• Minimum subject illumination may change when [AGC Limit]
is set.
• If [On2] is selected for [Image Stabilizer], it is best to select a
video size smaller than "960 x 540".
• The image stabilizer is not effective when the subject is shaking.
• The image stabilizer is not effective beyond a certain level of
vibration or against momentary vibration.
