   The whole RoadSense AI

   A pole camera records an encrypted traffic study on a memory card; the office hub counts vehicles by turn and class from the video.

2. 02Brain

   Raspberry Pi Zero 2 W

   The brain: it runs the rs-rec program

3. 

   03

   Camera Module 3 Wide

   Films the intersection at 720p, 15 frames a second

   Raspberry Pi Zero 2 W · CSI ribbon cable · Video frames

4.

How the parts connect

RoadSense AI, wired up

Every part, what links it to the brain, and how the data reaches your phone. A solid line is a cable; a dashed line is a radio link.

The program

What controls RoadSense AI

while (state === 'RECORDING') {
  const seg = await rpicamVid({ width: 1280, height: 720, fps: 15,
                                bitrate: '2M', seconds: 300 });
  await age.encrypt(seg.file, FIRM_PUBLIC_KEY);   // X25519
  fs.rm(seg.file);                                // only the .age file stays
  sidecar.append({ start: seg.start, frames: seg.frames, lux: seg.lux });
  const view = viewMatch(referenceFrame, seg.lastFrame);
  if (view < 0.5) mqtt.event('view_moved', view);
  if (battery.volts() < 12.0) { state = 'LOWBATT'; manifest.end('END_LOWBATT'); }
  if (rtc.now() >= schedule.stop) state = 'SLEEP';

The MUTCD keeps phases with the controller and lets detectors place calls; video detection needs a camera per approach, often on its own arm (about $15,000 for a four-approach intersection in a Cal Poly study), and street counters go on lamp columns; US DOT Safe Streets and Roads for All grants fund this safety data.

2. 27 Oct 2026, 07:20A builders’ merchant, timber yard or garden centre lets customers drive in, park, queue at the will-call counter and walk among forklifts. WorkSafe NZ fined a timber yard after a forklift knocked a pack onto a customer and asked yards to control people on foot and show customers where to park. Today each job is a separate tool: about $950 a truck for an AI reversing camera, $35 a month per camera for plate reading, paid processing for traffic counts and $859-919 per people counter.
