Typically 4 cameras setups where a single remote can control all of their cameras. For classical concert, they would use 2 PTZ robotic cameras and 2 mini cams on some artists and instruments. There is no camera operator at the camera side (for costs reasons) so a single operator has to do it all.
One important point, if you are not live, then there's usually the possibility to adjust everyting manually on the camera and then finish in post production so our remotes are nearly never used outside the constraints of live productions.
One the opposite direction, I heard that they had around 250 cameras on Love Island but you can pretty much control everything from one or 2 remotes as there isn't a need for a lot of changes at a single time. The action only happens in front of a few of them. That said, we still have 250 processes running and controlling these cameras continuously.
