I see two main differences between traditional and cctv-enabled surveillance, the first being that traditional surveillance requires participation and the second being that traditional surveillance is deployed after suspicion. These are not minor differences; participation means equal opportunity and "fair play", and it can't be stored for future use and retroactively used against people for future perceived transgressions. There is a limit to the traditional surveillance that a society would bear, while the latter is nearly invisible. It is a powerful tool to be able to track your political enemies at any point in the past.
