This is close to what I've always wanted to build; a camera watching the road next to me that records the speed of the vehicle traveling by. I should have everything needed from a simple camera setup, but I've not bothered actually doing it.

Since you have speed, I should dig into this.



I wanted that with noise levels. I'm so very tired of hearing illegally modified exhausts. It seems like an I2S mic would give calibrated levels.


Same here, I have a Pi 3 but I want to have this outside in the balcony, the question that always stops me is how to power it and what camera do I meed?


My plan was to stick the Pi inside, and power both it and the camera with Power over Ethernet (external-rated PoE cameras are a dime-a-dozen on Alibaba and friends).

I even got so far as to get it working with Zoneminder to dump out the clips that had motion, but didn't get further.

I actually have done something similar to this, since I had pretty clear view of the road infront and had my old android phone laying around,

Used to yolov5 to detect vehicles and deepsort to track them, also got a rough estimate for the speed of the pass

heres the two part blog i wrote about it

Could you show average speed vs car manufacturer? Or vs car type (compact, European luxury, minivan, truck). I've always wondered if this is correlated.


Would be interest; perhaps the red ones ARE faster.


The short ones are fastest.
