Speed Detection (radar?)

So this one may sound strange. I'm a former (30yrs ago long ago) Deputy Sheriff, but I still have maintained great relationships with the Sheriff's office. They asked if is there a way to measure someone's speed in an automobile automatically via the footage? I know you could measure the distance of two points, use a stopwatch, and determine if the car is speeding. They were asking if there was a way to do it automatically on the screen via another app, and/or also only capture motion for excessive speeding violations?

I've never seen anything like this, but thought I would throw it out there to see if others maybe had?

    I googled "security camera calculate speed"

    Proper calibration and authorized use are the key things that matter in court when it comes to speed detection equipment. If neither is acceptable to a judge or enough doubt can (easily) be established, it would be a waste of time to try and prosecute with standard security camera footage. Therefore the information would just be reduced to anecdotal. 

    I am certainly not a lawyer, but do have experience successfully defending myself in court against 2/2 speeding violations over the last two decades. Both times I called into question the accuracy and use of the speed detection equipment. I did this by filing a motion for the calibration and training logs, then used the actual operations manual of the speed detection equipment (radar and LIDAR). Long story short, there were enough obvious failures in how the officers maintained and applied the equipment that the judge threw out both cases. Their cases would have been stronger against me if they would have just stuck with the officers witness statement alone.

    We are already getting way off topic for what this forum is setup to offer, but I would say that the use of standard security camera footage for use in any type of traffic enforcement is too flawed for legal purposes. It would just be a toy. Of course there are manufacturers that specializes in such camera based systems where multiple levels of speed detection and calibration are incorporated, but certainly at a much higher cost and only available to law enforcement for a reason.

    BTW, coming from a 30 year retired firefighter, thank you for you service.


    Peace,

    Thanks guys, and no this is not for Traffic citations. It's part of a multi part evaluation, with lots of questions around abusive traffic behavior, time of day occurrences, behavior after someone has passed a radar sign displaying speed, sometimes youth or people of concern that simply need to be "talked" to, etc... It feels a little "big brother", but the goal is find out if we have a community issue or just some bad players.

    The state got $6M in grant funding for License Plate Reader cameras. Trying to figure out if there are ways to leverage the data from them better.

    There's a lot of ideas bouncing around, but don't read too much into this...it's simply a research project for now.
