I have several Nest Outdoor cameras. They are excellent, however, I don't believe that it will detect very small objects like a golf ball. My cameras detect small animals like skunks, cats and so on, but I don't think it would catch something that small. But you have to remember that the camera is always on and you can search the archive video to see if you see anything. I rolled a golf ball for you on my back patio to see if it will detect it. The camera did not notify me of any movement, but I was still able to see it on the playback. Hope this helps. Good Luck.
