Industrial camera for overhead sports recording
 

I need to record a sporting event from above. I want to run an cable back to my PC and record directly to my hard drive. I have tried webcams and the resolution is very poor. A 1 mega-pixel min. would give me the quality I need. I need the ability to mount a very, very wide angle lens. Anybody have any idea's. I will use 5 cameras at each event so cost is a factor.
