At 700 feet you're going to need more than a Z4E. A 5241B-Z12 wouldn't be enough. Maybe Andy has a recommendation besides the obvious one of a PTZ, 49225 should do it but that's in the $300-400 range and a pretty big camera when compared to a 5442T.
I am planning on installing soffit lighting in the front and back too in the spring. Should I be concerned about my camera choices?
