FanCam or some such equivalent is pretty much universal these days, at least amongst clubs who have TV screens in the stadium. We have similar. Luckily I sit high up so never get picked out by the cameraman.
I do have a particular loathing for goal music though. The Albion promised when we moved to the Amex that we'd never have it. Our goals are treasured enough: they don't need poxy Chelsea Dagger to "enhance" the moment.
