One or more cameras
One or more cameras: one camera during live production limits us to filming a wide shot most of the time, to make sure we don’t miss anything. This probably means few or no close ups (depending on the event), no facial expressions etc. Two or more cameras allow us to shoot different framings, so one wide, medium, close for example, as well as different angles. More cameras mean more security (if one shot is going out of focus or if the camera has a problem we can switch to the others), more variety and more dynamism.
