Building a 203 camera system for recording Soccer

I am building a self containing system to record my kids Soccer and basketball games. I am hoping for help on the best camera to use, that will record video from a distance. so that i can setup the case in the stands, and have one camera for each side of the field. I am thinking of a 3rd camera that would point at the score board. so 2 cameras shoud have a FOV of about 120 degrees and the 3rd camera would be something that has a good zoom. auto focus i think woud be best, but i dont know since there will be several focal points.

and help would be great
