Thanks for the replies.
The color on the Arecont was harsh. Particularly with high contrast items, i.e. having several pieces of white paper on a black countertop. The software has no contrast control, perhaps that is the issue with it.
As far as the Avigilon is concerned, I don't see it as a supported camera on Exacqvision's website. If it would work, I'd certainly give one a try.
Thanks,
