How to Configure Abandoned Object Detection
Set the area you want to detect an abandoned object in as a detection area.
Select [Rectangular] or [Polygonal].
1
In the video display area, draw the area in which you would like to detect abandoned objects (P. 166).
2
Configure the size of the object needed for detection in [Object Size (%)].
3
This determines how large the abandoned object must be in the detection area you set in step 2 to detect as an
abandoned object.
When the setting values or slider is changed, an indicator representing the object size is shown for one second in
the center of the video display area allowing you to check the size ratio while setting.
4 Configure [Duration (Sec)] for the time required for an object to be detected as an abandoned object.
Detection Status for Abandoned Object Detection
All moving objects detected are displayed with profile lines.
If [Object Size (%)] and [Duration (Sec)] are not met, profile lines are white.
If both [Object Size (%)] and [Duration (Sec)] are exceeded, the profile lines take on the same color as the detection
area, indicating that "detected" mode has been triggered.
