Motion detection does not trigger video file creation #2792

Open faocrates opened 3 years ago

faocrates commented 3 years ago

I've recently setup motioneyeos on my Raspberry 3B+ (using the R3B+ OS image) and use it along with a USB camera equipped with a Sony IMX291 image sensor. Configuration changes I made were to add files to a Samba network folder, enable Movies (motion triggered) and Motion Detection (threshold left at 2.6%). All other configurations were left to the initial defaults. Connectivity is through WIFI.

The camera looks over a parking lot, sometimes there will be three cars parked (distance to the cars ~8-10 meters). I'll have a stored video in the remote SMB folder showing three cars parked (all idle) then the next video shows two cars parked (again all idle) but the video in between that should show one of the cars moving out of the parking lot is never stored! Somehow it seems like any major movement does not result in a stored video file, while some minute changes are stored (with main subjects captured remaining idle). Really puzzled by this issue, any help or advice would be greatly appreciated.

I usually start with Frame Change Threshold set to 0.1% and move it up until I don't get very many 'false positives'. I also turn on 'Show Frame Changes' until I get to the settings I want. To minimize false positives, especially in twilight and dawn, I turn on Despeckle and Auto Noise Detection. I do not turn on Auto Threshold Tuning. I set Motion Gap to 2 seconds Capture Before 10 frames Capture After 10 frames Minimum Motion Frames 2 have always been a good place to start, too.
