I don't know about the use of cameras for swim, either. I just meant that we were able to see what happened because of them.
According to another thread I took part in someone said the Japanese swimmer was seen doing the dolphin kick on the Jumbotron and everyone started booing...most likely swim parents, he said, LOL!
They're not Jumbotrons -- they are South Dakota-made Daktronics ProStar units. The Brookings, SD manufacturer has the contract by Swatch to provide all video boards.
But officials at FINA cannot use the spectator-friendly ProStar units. They must officiate from their poolside points, and cannot use replay cameras.
