Sure there are, and we worked this out decades ago with telecommunications. We ought to:

- Require a judicial warrant before recording anything. Recording with a camera network is now considered a 4th amendment search, and scope must be minimized to prevent harm to the public.

- Police must articulate a probable cause for a search, and can only record locations for specified vehicle or individual traits during a specified time window as approved in the warrant.

- No BS with recording everyone and searching the existing database of every public movement whenever you want; this is a "dragnet" and is unconstitutional or highly contested in other contexts (e.g. geolocation).
