2. Set the alarm holding time and alarm trigger options. The setup steps are the same as
motion detection. Please refer to 4.4.1 Motion Detection for details.
3. Click “Save” button to save the settings.
4. Set the alarm area of the abandoned/missing object detection. Click the “Area” tab to go
to the interface as shown below.
Set the alarm area number and then enter the desired alarm area name. Only one alarm area
can be added. Click the “Draw Area” button and then click around the area where you want to
set as the alarm area in the image (the alarm area should be a closed area). Click the “Stop
Draw” button to stop drawing. Click the “Clear” button to delete the alarm area. Click the
“Save” button to save the settings.
5. Set the schedule of the abandoned/missing object detection. The setup steps of schedule
are the same as the schedule recording (See 4.1.4.1 Schedule Recording Settings).
※ The configuration requirements of camera and surrounding areas
1. The range of the detection object should occupy from 1/50 to 1/3 of the entire image.
2. The detection time of objects in the camera shall be from 3 to 5 seconds.
3. The defined area cannot be covered frequently and continuously (like people and traffic
flow).
4. It is necessary for abandoned/missing object detection that the drawn frame must be very
close to the margin of the object in enhancing the sensitivity and accuracy of the
detection.
5. Abandoned/missing object detection cannot determine the objects’ ownership. For
instance, there is an unattended package in the station. Abandoned object detection can
detect the package itself but it cannot determine to whom it belongs to.
6. Try not to enable abandoned/missing object detection when light changes greatly in the
scene.
7. Try not to enable abandoned/missing object if there are complex and dynamic
environments in the scene.
8. Adequate light and clear scenery are very important to abandoned/missing object
detection.
