• Click [Clear] to delete the polygonal detection area.
• The camera tampering detection area cannot be changed.
Changing a [Rectangular] detection area into a [Polygonal]
shape or changing a [Polygonal] detection area into a
[Rectangular] shape
Changing the shape of the detection areas already set
deletes that area and switches to a new drawing setting.
„ Setting the Detection Line
Use the image display area to set the detection line.
Specify a detection line consisting of a polygonal line with
a maximum of 32 angles.
In the image display area, click the start point of the
detection line and then click the end point. To create a
detection line consisting of polygonal line, click each
angle in the polygonal line in order.
To confirm a detection line, click any of the already set
angles.
The angles in a confirmed detection line can be dragged
to change the shape of a detection line and lines between
angles can be dragged to change the position of the
detection line.
Note
• Drag the square marks ( ■) at each angle to change the shape
of the detection line.
• Click [Clear detection line] to delete a detection line.
„ Setting Detection Criteria per Detection Type
Specify different detection criteria for each detection type.
Detect criteria for [Moving Object Detection]
Set detection areas where you want to detect moving
objects.
For [Object Size (%)], enter a value or move the slider to
set the ratio of the size of an object moving in the
detection area to the size of the detection area.
When the ratio of an area where the camera has detected
a moving object exceeds the value set for [Object Size
(%)], detected mode is triggered to ON.
When [Object Size (%)] is changed, an indicator frame
showing the size of the object is displayed for 1 second in
the center of the image display area, allowing
specification of the settings while checking the size ratio.
Any moving objects detected are shown with contour lines.
If a moving object is smaller than [Object Size (%)], its
contour lines are white. If the moving object is larger than
[Object Size (%)], its contour lines take on the same color
as the detection area, indicating that “detection” mode has
been triggered to ON.
Detect criteria for [Abandoned Object Detection]
Set areas where you want to detect abandoned objects as
detection areas.
[Object Size (%)]
Enter a value or move the slider to set the ratio of the size
of an object that was left behind in the detection area to
the size of the detection area.
When [Object Size (%)] is changed, an indicator frame
representing the area of the object is displayed for 1
second in the center of the image display area. This
allows you to check the size ratio of the abandoned object
detection area while specifying the [Object Size (%)]
setting.
[Duration (Sec)]
Set the time that must elapse after an object has been left.
If both the values for [Object Size (%)] and [Duration
(Sec)] are exceeded, detection mode is triggered to ON.
