That's what everyone here at Oakbar calls the TV that is connected to our barn camera. We put it in a couple of years ago so we could watch the calving pens without going outside and bothering the cows. It works great and its more than paid for itself by letting us see any calving problems as they develop without the cow knowing it. In two years I would say we've probably saved at least 2-3 calves in our small operation that would have otherwise died or at least had major problems. I've even had phone calls from my wife telling me that a cow is in labor or having trouble when I'm on another part of the farm. Its also reallly nice to check on them in the middle of the night from the house rather than go out on a cold north Iowa night. I'm watching one right now that should calve within the next day or two.
I'm warning you, though, all our city friends think its a little funny that we sit at our kitchen counter and watch the cows calving. No doubt we're the epitome of "Redneck" to them!! Somehow, if they're here when a cow gives birth, they all seem to learn something and never forget it!!
