I have been trying to tackle this type of "Feature" but object detection and action detection seem to be a totally different problem. Use case: I want to "detect" when a car does not stop at a stop sign. I have researched this over youtube, reddit, etc and other than training it myself there are no models already out there, including YOLO. Can anybody offer advice on how to achieve this use case?

Try building up a method iteratively. Start by calculating the speed of a car as it crosses the camera frame.

Then try calculating the speed between two points (in car length in front of and a car length behind the stop sign).

Then set a threshold for how fast is too fast for a car to realistically go between those two points without stopping. Get notified with a video snippet when a car is above this threshold. Adjust the threshold based on the videos you are capturing.

It won’t work if your object detection is not running at your camera framerate.

My reolink cameras indicate on the clip the length of time the object in motion was recorded. One can probably figure out a way to bin these clips according to this length of time as a proxy for speeding through the stopsign.

With ByteTrack or other similar algorithms I don't think it would be too difficult. If you're looking to contract the work out I could give it a go.
