Radar sees movement. It cannot see a face. Privacy is a property of the hardware, not a promise in a policy.
The sensor records how objects move: their distance, direction and speed. That is enough to classify them.
No photos, no video, no faces, no biometric data. There is nothing to blur, redact or leak.
Classification runs on the sensor. Events go to your own systems on site, not to a DPLR cloud.
