Flock & ALPR Cameras in Union City, California
Volunteers have reported 57 automated license plate readers in and around Union City — cameras that log every passing plate with a time and location.
Jurisdiction · by recorded street address
The 57 cameras counted on this page are every reader mapped within about 20 kilometres of Union City, so the count crosses municipal lines. By the street address recorded for each one, 31 of them sit inside Union City itself.
The rest sit in Fremont (15), Hayward (11).
8 of them name an operator in the record: California Highway Patrol (5), Kaiser Permanente (2), California Highway Patrol (CHP) (1). The operator is who runs the camera, which is not always the local government.
