Wrap a tripod in some soft sponge for shock protection and bungee cord it to the fence outside?
Use a tripod with a geared elevator and bungie cord it to the fence with the sponge between the fence and tripod. Use the geared tripod elevator to raise the camera to look through a hole in the fence. Make something to block the fence hole so that a ball can't get through - a piece of plywood with a hole in it that the ball can't get through.
If a ball hits the fence and there is no sponge/shock absorber the shock might cause damage.
Someone mentioned that possible theft might be an issue with a camera outside the fence.........
Some other ideas in an earlier reply on camera protection.
