That's probably exactly what they did, deployed a sbc + some off the shelf model and increased the price 300x by making a black plastic shell.

I guess that they are implementing crappy cameras? Not sure about american plates, but in most jurisdictions licence plates are optimized for easy OCR:

Note how each letter is unique and can't be transformed with a sharpie into another. That also makes OCR easy. If you use a crappy dashcam, you will get problems regardless. Esp. in low light situations at higher speeds.

So I would guess that Flock uses cheap sensors and cheap lenses. Which kind of makes sense when they are putting out thousands of scanners.

If you have a million stolen licenses, but on the road remain very few, say 1k. While there are say 100m other cars. If you now have 99% accuracy, you will read 990 stolen cars, and misread 1m plates. Since 1% of plates are stolen, you randomly hit 10k of those misreads into a stolen plate.

This is generally alwayd an issue with rolling out mass tests. If the thing you search is even rarer than your failure rate, most detections are errors no matter how good your test.

This is why we don't just test everyone for diseases all the time even when it would be very cheap and simple.

since its a mass surveillance apparatus, the juror/court was not its intended purpose. they likely profile(errenously) potential people who are going to be a "nuisance" in the future.

don't forget to clap

huh. i wonder if they don't have them around my town because the test one they put on the bike route i take to the next town acquired so many holes without my help i felt i didn't need to add.

Doing God's work!

But on the other its not, as it can cause someone else with a similar plate number to be accused of a crime or infraction, etc that another committed.

No. Its like drug dogs. Its just an excuse to do whatever they want. Infinite monkeys writing up probable cause forms.

If they flag all the plates, they're bound to get all the ones they're aiming for. It's a simple solution.
