ALPR PRIVACY / AN INDEPENDENT DIY PROJECT
Your journey.
Your privacy.
A GPS-aware ESP32 controller that compares your location with a local database of reported plate-reader cameras.
The prototype uses that match to control a relay and indicator. The proposed privacy panel switches from clear to opaque near a mapped camera.

FROM LOCATION TO ACTION
How the prototype works
- 01 / LOCATE
Find your position
A GNSS receiver supplies the controller with a position and accuracy estimate.
- 02 / COMPARE
Check the local map
The ESP32 compares usable fixes with camera geofences stored on the SD card.
- 03 / RESPOND
Control an output
A confirmed geofence match activates the relay signal and external indicator.
BUILD AT YOUR OWN PACE
A small controller.
A documented project.
Start with the parts, follow the bench checks, then learn the maintenance interface. The guides identify what is established and what still needs validation.
