Are there tutorials on how to do this? Should it be set up on a server on my local network??? How hard is it to set up? I have so many questions.

It’s possible to still track speed using a video feed instead. You just have to know the distance between two static points within the videos frame. Time naught = passes first static point, time final = passes second static point.

Velocity = distance / time

Although I’m not sure how or if this would impact the battery life of the device.
