Keep logging and reporting, not sure I would agree that councils have power to remove cameras though , because probably those that did , didn't pursue what powers they actually have and follow a course of action with them , most people want the problem to go away if that makes sense.
Evidence is crucial , also look up the info on nusciance neighbours I seen people get also done by councils and courts although it takes a long time and patience to log and report log and report , eventually you will hopefully be on winning side
Some people do deserve action against them
