Who works the cameras in a TV station?

It depends on the production. For dramas, sitcoms, sports and similar productions, most cameras have an operator behind the camera. The operator is responsible for moving and directing the camera according to a director's instruction, focusing and all the other small but important tasks. Some cameras may be fixed while others might be controlled remotely from the gallery.
Many regional news programs are moving to cameras that are controlled by the news presenter himself and others are using fully automated cameras that will move, pan, tilt, zoom and focus under the control of a computer without any manual intervention. News programs are leading the way in automation because they are fairly predictable programs from a technical viewpoint. Automation has added a reliability to local and regional news because the computers are very good at remembering all the details of a particular shot.

However, automation in many other program genres isn't possible because of the limitations of the computers. They are unable to react to unexpected situations in the same way a camera operator can. A good operator will always frame a shot well even if the performers move off their marks. Our new robotic camera systems haven't learnt those subtle adjustments just yet.
