Canon VB-S30D Operating Manual page 113

Any moving objects detected are shown with contour
lines. If it is smaller than [Change Ratio (%)], contour lines
are white. If the video is changed for an area larger than
[Change Ratio (%)], contour lines take on the same color
as the detection area, indicating that "detected" mode
has been triggered to ON.
Note
Detection will not be possible for three seconds after the change
ratio is modified when camera tampering detection is selected, or
when switching into camera tampering detection from another
detection mode.
Detect criteria for [Passing Detection]
Set the passing direction and decision point of the moving
object for the detection line that the moving object will
cross.
[Passing Direction]
Select the direction for moving objects to pass the
detection line. When an object that moves in the selected
direction passes the detection line, "line crossed" is
detected.
A preview display shows the selected passing direction
on the detection line in the video display area.
[Decision Point]
Select the decision point of a moving object in
accordance with a detection line. When a decision point
selected here crosses the detection line, "line crossed" is
detected. In the video display area, a cross mark is
displayed to indicate the decision point in the detection
frame.

[Object Size (%)]
Enter or use the slider to set the size ratio of moving
objects for the entire screen.
When a moving object exceeds the value set for [Object
Size (%)], it becomes a passing detection target.
When [Object Size (%)] is changed, an indicator frame
showing the size of the object is displayed for 1 second in
the center of the video display area, allowing specification
of the settings while checking the size ratio.
Important
Perform a detection test in advance to make sure that the
detection frame continues to be displayed for a subject
targeted for passing detection.
Note
• A ratio of up to 30% can be set for [Object Size (%)] in passing
detection.
• A passing detection event is notified only when the decision
line is crossed. Take care in setting the operation to be
performed when an event occurs.
Setting by Right-Click Menu
Right-click on the Intelligent Function Setting Tool display
screen to display the menu. There, the following functions
can be used.
[Copy detection area/line]
Copy the detection area/line of the detection setting
selected.
[Paste detection area/line]
