So appreciate all the great input.
I can sure sympathize with other posters who are claiming major headaches. I have spent an entire day researching cameras and literally have one.
From my current assessment it appears I would need something in the range of 25-30mm or a varifocal 5-50mm, which I have seen. The prices however are far more than I want to spend at this time so I think I will compromise and try a 12mm. I think the mistake I was headed for was trying to cover too much area with too few cameras. So thanks for setting me straight on that as well..
