This sentence struck me as well. It says what it is focused on, but nothing about what it actually captures. What I would like to see is something like this: - The detectors have a per-determined list of suspect faces and only record information when those faces are spotted. - These detectors keep only a fixed length of recording that is permanently deleted unless it is actively linked to a crime and explicitly held as part of that investigation. But it says nothing concrete. Just some nonsense about "focus" which doesn't mean anything.
