Watching the watchers

Cameras that watch<br>government vehicles.<br>Owned by nobody.

Volunteers point a spare phone at a street. It reads the vehicles that go past,<br>keeps the government ones, and destroys everything else on the device ,<br>before anything is sent anywhere.

Kept<br>Government vehicles

The photo and the plate are kept, and they become the public record. Public money, public roads, public vehicles.

Destroyed<br>Everybody else

The plate is destroyed on the camera itself, before anything leaves it. What reaches the server is an anonymous dot with no photo and no plate.

Running a camera

There is nothing to install and no account to make. It runs in a browser tab on a<br>phone you have already stopped using, propped in a window.

The detection runs on the phone, not on a server. That matters more than it sounds:<br>if the video were uploaded for a server to look at, there would be a video feed to<br>intercept. There is not one.

Works on an old phone, a laptop webcam, or a USB camera

No account, no sign up, no app store

Your camera's exact location is never published, only the street it watches

You can shut it off and take your camera out of the network at any time

Want an always-on camera?

A spare PC with a webcam can run the full detector locally — it tells a<br>patrol car from an ordinary one on the machine, and reads plates. One<br>command sets it up and starts contributing to the map:

Windows: run irm https://sparrowmap.com/install-node-windows.ps1 | iex in PowerShell, or download SparrowMapCameraSetup.exe

Linux (help us test): curl -fsSL https://sparrowmap.com/install-node-linux.sh | bash

Everything still runs on your machine — only detections leave it, never video
