Nope. You are referring to one extrapolation a journalist made, when they assumed all streets in the UK have as many cameras as a single inner-city street. This has led to the commonly-spread, factually-inaccurate, rarely-refuted meme of Britain being drenched in state-owned cameras. It's patently untrue. The vast majority of cameras are in private hands, watching their property for thieves and/or vandals, etc. They are also covered by EU data protection regulations (for now), which are squarely on the side of the data subject (the public in this case).
