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
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.
[Duration (Sec)]
Set the time that must elapse after an object has been left
behind.
If both the values for [Object Size (%)] and [Duration
(Sec)] are exceeded, detection mode is triggered to ON.
Any moving objects detected are shown with contour
lines.
If [Object Size (%)] and [Duration (Sec)] are not exceeded,
contour lines are white. When all detection criteria are met,
contour lines take on the same color as the detection area
and “detected” mode is triggered to ON.
Detect criteria for [Removed Object Detection]
Set detection areas for objects whose removal you want to
detect.
For [Duration (Sec)], set the time that must elapse after
the object has been taken away. Detected mode will be
triggered to ON when an object is taken away from the
detection area for a period longer than the set [Duration
(Sec)].
Any moving objects detected are shown with contour
lines. As long as [Duration (Sec)] has not elapsed,
contour lines are white. When [Duration (Sec)] has
elapsed, contour lines take on the same color as the
detection area, indicating that “detected” mode has been
triggered to ON.
Detect criteria for [Camera Tampering Detection]
For [Camera Tampering Detection], the entire image
display area becomes the detection area. “Detected”
mode will be triggered to ON when the image is
obstructed for an area exceeding the ratio set [Change
Ratio (%)].
When [Change Ratio (%)] is changed, an indicator frame
showing the obstructed area is displayed for 1 second in
the center of the image display area, allowing
specification of the settings while checking the ratio that
the image display area occupies.
Any moving objects detected are shown with contour
lines. If it is smaller than [Change Ratio (%)], contour lines
are white. If the image is changed for an area larger than

Important
Set detection areas for removed object detection so that they
precisely match the contours of the object in question.
Influence from the target object's shadow or adjacent objects
may result in the target object being recognized as larger than
actual and will not trigger Removed Object Detection. In such
cases, reconfigure the detection area to outline the recognized
target object.
