Canon VB-S30D Operating Manual page 48

[Auto]
Automatically uses haze compensation.
(11)[Day/Night]
Set Day/Night mode to [Auto], [Day Mode] or [Night
Mode] when the camera starts.
You can also switch between [Day Mode] and [Night
Mode] using the Day/Night mode function of the
Admin Viewer (p. 144).
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. 141).
• If the subject is a traffic signal or electronic scoreboard, etc.,
the captured video 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.
• Even if [AE Mode] is set to [Auto (Flickerless)] or [Auto
(Flickerless 2)], some screen flicker may still occur under
unstable light source conditions.
• 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)], [Auto
(Flickerless 2)] or [Auto (Shutter-priority AE)] (p. 143).
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.
• Though the camera has an infrared filter, there is no effect on
lighting due to infrared light as the camera does not have an
insertion/removal mechanism for the filter.
• The Day/Night Mode can be switched manually via the Day/
Night function of the Admin Viewer (p. 144), or via the
[External Device Input] (p. 61) or [Timer] (p. 62) settings in
[Setting Page] > [Event].

The higher the digital zoom ratio, the lower the video
quality becomes.

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