Note
The reliability of object detection depends on local factors. In various situations, false
alarms can occur. In particular, environmental influences such as rain, snow, insects, dirt
and difficult lighting conditions can have a negative effect on the results.
To achieve an optimal performance of the object detection, certain frame conditions have to be
considered during the installation or the field of view of the camera (see also section 7):
1. The installation height of the camera should be chosen between 2 and 3 meters.
2. The object height in the selected image section must be between 1/16 and 1/2 of the image height.
If objects in the image are displayed too large or too small, they may not be detected correctly.
3. Note that below the camera a certain area is unmonitored.
4. Reflective surfaces in the image section can irritate object recognition.
5. Make sure that there are no branches or leaves in the close-up range of the camera in the image
section.
6. Do not use object detection in areas with a correspondingly high number or frequency of objects
(people, vehicles). This will result in a high number of alarms.
