Im waning to get a couple cameras to put in the calving barns. Getting tired of 2 or 3 night time checks. One barn is right at the house, 2-300 feet, the other is 3100 feet. Not sure if there is anything with that kind of range? Doesn't have to be anything fancy, just reliable. I have looked up old threads but the links were all out dated and no good. I don't need a monitor, I have both smart phone and an iPad. Any help would be much appreciated.
