Lots of buses are equipped with CCTV. Backhauling this to a real-time surveillance and control centre goes some way to making bus travel safer and therefore more attractive (or less unattractive, anyway). All 8000 buses under Transport for London have on-board CCTV, but so far the video has been stored on the bus rather than transmitted in real time.
