Wow, that does sound like a fun project, especially if he has a budget.
Although the Canon C50 doesn't have built-in POE capabilities, you can't get better PTZ, and you could use POE modules. Visitors could really check out close-up views of that scenery you mentioned
. There are also several Axis models that support either built-in or splitter module POE. Do you need enclosures or will the cams be under a cover, out of the weather? I think that having at least one PTZ for event viewing would be nice, maybe a second stationary cam that covered the entire main court as well.
Wish I had your opportunity. The only cam project I've run across was putting one at the top of Rio Blanco hill in the dead of winter so the County could see the weather conditions and know if they needed to send out the plows!
