I’ve mounted my camera to a telephone pole and it’s about 20’ high. The location it’s in is not the best for a camera so capable. SO, I’m going to drop a 3”x1/4 wall square tube in the ground about 4’ at a more advantageous location. I was thinking about 16-17’ high. Has anyone mounted a ptz to square tubing this high up? Should I expect any shaking?
