Continuous surveillance is not just valuable in entertainment, it is ubiquitous in the security industry. But less obvious adaptation of surveillance has always played a role in aviation safety. The so called black boxes are a mandatory requirement in commercial aircraft. They record all the flight performance data and cockpit conversations, which later become useful for investigations of aviation incidents and accidents. You can term it as a form of Big Brother, continuously recording events, albeit for safety reasons. And now, the healthcare industry is adapting continuous surveillance in attempts to reduce medical errors and improve overall healthcare safety.
