    So, my town has asked me to try and build them something that will be mounted next to the road. Big flashing sign "Local PD welcomes you" - they want it to scream surveillance. The cars will pass by at 50mph or so.

    The goal isn't to read the plates (but I'd like to be able to) - but to get a clear picture of passing vehicles.

    The good thing is I'll have a great angle on the cars. The bad thing I have a "petty cash" budget.

    My the budget is super tight (less than $650).

    So my first shot at this was an IR LPR camera (generic) from Alibaba and a raspberry Pi.

    The camera takes stills and FTPs them, but when it's sending the image, it ignores the next car.

    So I started trying to grab frames from the RTSP stream, and bought a radar from Omnipresense, and when a car comes within rage, copy the frame from a ram drive.

    Well, the frames are all noisy and blocky, or if the car is moving more than 30 mph, smeared.

    So - my question is - if you were going to build this - which camera would you use? Knowing it would be mounted at least 8 ft up - and be as close to the highway as a stop sign?

    I'm still working on the software side - I've tried ffmpeg but I'm starting to think it's not the answer. I think I need some type of motion detection. Maybe motion app, or something like that.

    Any tips on where to start? I can write software, but I'm not codec / ip camera guru.

    Do you think a Raspberry pi is adequate for this? Should I look at something more powerful?

    Hi Marble -

    I would be very cautious on this sort of civic project - there can be significant legal issues and legal challenges - and if they can only give you a budget of $650, well then I am concerned that they will be unable to handle any legal challenges or record requests ( example - FOIA, Open Records challenges, .. etc )

    Yeah - I was thinking about stuff like that.

    This isn’t for speed enforcement, and the like. More a crime deterrent.

    That being said - is it technically possible using a Pi?
