In this new firmware (ver. 4.x.6.218), we upgraded the vision algorithm for motion detection. Depending on the specific scenario, some movements (such as moving leaves and tree branches) may be more sensitive to the vision algorithm.
We recommend using the green rectangle that is generated by the motion tagging to identify the motion detection zones. The green rectangle indicates the largest rectangle of the moving objects.
The motion detection is triggered when there is an overlap between your active detection region and the green rectangle. We are not displaying the green rectangle if it doesn’t overlap with the active detection zones. However, if there is any overlap, even if it is very small, the vision algorithm considers that as a trigger of motion detection.
