I'm attempting to build something with a Raspberry Pi that can hopefully capture moving vehicle's license plates 50-100 ft away (and at night). I understand very little about photography, but through my own research as I understand it, the focal length needs to be decently large in hopes of getting a high enough resolution at this distance.
If necessary, I can build a panning motor to put the camera on that will constantly scan around (assuming there is no low focal length/large FOV camera that can capture this information). I'm also concerned about if there are headlights next to the plate, wouldn't the aperture have to be low in hopes to see anything?
So far I've been lead to these two products,
A Rapberry Pi HQ 12.3MP IMX477 Camera
A 35mm focal length lens with adjustable aperture
Would the manual focus on the lens be an issue? Is there any better way to achieve this(if this even works), and how would IR affect the situation?
I understand this is a specific situation and probably has a complicated answer, but any type of ELI5 answer as to how I can achieve this would be amazing, I've been fumbling for hours trying to understand how something like this might be achievable.
