We bought our setup from this place http://www.spyshop2000.com/the_barn_special.htm a couple of years ago. 4 cams, quad processor 3000 plus range for foaling. Plug and play easily installation worked perfect at first asking. TV quality color during the day, and excellent night vision, Black and white. Perfect color with stall lights on. Surprisingly inexpensive. Really nice people to work with.
