Public money, public roads, public vehicles\. Destroyed ### 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 phone you have already stopped using, propped in a window\. The detection runs on the phone, not on a server\.

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?
