Filmmakers render aspects of nature, human activity and imagination visible. The documentary film continues to be a potent form in all its variety, from the personal video diary to “objective” fly-on-the-wall shoots, to the hybrid fact/fiction (“faction”) film. But the most prolific documentarists are no longer to be found in film schools and TV stations. In some European and American cities, every street corner is under constant surveillance using recording closed-circuit TV (CCTV) cameras. Such cameras are typically operated by local government, police, private security firms, large corporations, small businesses and private individuals, and may be automatic or controlled (zoomed and panned) from a remote control room. Filmmakers, and in particular documentarists of all flavours, should reflect on this constant gaze. Why bring in additional cameras, when much private and public urban space is already covered from numerous angles?
