That's the problem with motion detection on dash cams; either you get false triggers or the camera may fail to record. Motion detection is really a technology from the CCTV industry that is intended for use in a static environment such as a warehouse, office environment or retail space at night when no one is around. I can see it being used for dash cams in a similar static environment such as a parking garage. Outdoors, there are numerous things that cause false triggers such the aforementioned trees blowing in the wind and also pedestrians, stray animals, birds flying past, moving clouds etc. can all trigger the camera. Now in my ninth year of dash cam use and experience has taught me to avoid motion detection entirely.
Most CCTV systems have the capability to mask off areas within a grid where you do not want motion detection to function specifically for avoiding false triggers or for designating a zone of capture where you anticipate motion such as a doorway. Does the A129 have this? If not, and if the DSP is capable perhaps it would be a good addition to the buffered parking mode feature? One could create a "bubble of motion detection" within a designated distance surrounding one's vehicle.
Here masking is used on a CCTV cam to avoid triggers from the motion of the trees.
