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 over an area exceeding the ratio set in
[Change Ratio (%)].
When [Change Ratio (%)] is changed, an indicator frame
representing the area that can be obstructed is displayed
for 1 second in the center of the image display area. This
allows you to check the change ratio of the camera
tampering detection area, which occupies the entire
image display area, while specifying the [Change Ratio
(%)] setting.
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
[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.
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.
