As a general note, having done work in automated surveillance, most people are too upset of the level of UK surveillance. The current system is not automated, meaning that humans need to watch the 4 million feeds. But expert humans miss 95% of events after 20 minutes from a single feed. Imagine how that decays for many cameras per operator.

I would love all public officials to wear these cameras. They would need to be on all the time, outside private spaces or security clearance requirements.
