CATHEXISVision ANPR 02: Essential Requirements for a Working ANPR System
The short version: A Cathexis engineering tutorial on ANPR camera specs is a reminder that plate surveillance is precision-built infrastructure, not an accident.
Our Take
This one isn't a news story or an exposé — it's a vendor training video from Cathexis, a video management software company, walking installers through the technical requirements for a functioning ANPR (automatic number plate recognition) setup. Plate size in frame, lens angle, lighting, mounting height — the nuts and bolts of making a camera reliably read your license plate at speed. Credit to Cathexis for putting out plain, practical material; it's not aimed at the public, but it's useful to us anyway.
Why useful? Because it strips away the marketing language and shows how deliberate this technology is. Flock Safety and its competitors didn't stumble into mass plate tracking — they engineered toward it, spec by spec, the same way this video walks installers through it. When you see a camera bolted to a pole at the entrance to your neighborhood, it wasn't placed casually. Someone followed a checklist a lot like this one to make sure it could capture, timestamp, and log every plate that passes, all day, every day.
Videos like this are a good reminder that the fight against blanket ALPR surveillance isn't just about privacy slogans — it's about knowing the hardware well enough to spot it, question it, and push back on it in your own town. Check our camera map to see what's already been logged near you, and hit take action if you want to do something about it.
