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 object removal 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. Object removal detection cannot determine the objects’ ownership. For instance, there is an
unattended package in the station. Object removal detection can detect the package itself but it
cannot determine to whom it belongs to.
6. Try not to enable object removal detection when light changes greatly in the scene.
7. Try not to enable object removal detection if there are complex and dynamic environments
in the scene.
8. Adequate light and clear scenery are very important to object removal detection.
