Important Set detection areas for removed object detection so that they precisely match the contours of the target object. Influence from the target object's shadow or adjacent objects may result in the target object being recognized as larger than it actually is and will not trigger removed object detection. In this occurs, reconfigure the detection area to outline the recognized target object. 3 Configure [Duration (Sec)] for time required for an object to be detected as a removed object. Detection Status for Removed Object Detection All moving objects detected are shown with contour lines. As long as [Duration (Sec)] is not exceeded, contour lines are white. When [Duration (Sec)] is exceeded, contour lines take on the same color as the detection area, indicating that "detected" mode has been triggered. 6 Contours of Moving Object Detected as Removed Admin Tools  How to Configure Camera Tampering Detection For [Camera Tampering Detection], the entire video display area is the detection area. The area cannot be changed. In [Change Ratio (%)], you can set the ratio of screen change for tampering detection to be determined in relation to the entire video display area. When the setting values or slider is changed, an indicator frame representing the area of the entire video display area that can be obstructed is displayed for one second in the center of the video display area allowing you to check while specifying the setting. Change ratio indicator Detection Status for Camera Tampering Detection All moving objects detected are shown with contour lines. If an object is smaller than [Change Ratio (%)], its contour lines are white. If the obscured area in the video exceeds [Change Ratio (%)], contour lines take on the same color as the detection area, indicating that "detected" mode has been triggered. 223
