In locating the hard cam I always look for a spot that’s square on to the ring and ideally with the crowd behind it, but if that’s not possible then with crowd somewhere in shot, like in front of it or off to the side. Depending on how good the hardcam works out depends on how much I’d use it vs a ringside camera. Sometimes it can be very hard to get the right height, in our gym shows we have a platform that’s pretty much the only place you can set up a camera but it’s essentially a roof cam… other places can be too low at times, I don’t have people manning the hard cam usually it’s locked off.. it’s also mostly a phone hence harder to man or use in any meaningful way… but yeah.. that’s me anyway. I prefer crowd in shot rather than entrance way in shot anyway..
