Netgear Arlo 4k surveillance system. With auto zoom focus tracking

I'm retired DoD computer Science, I also have Ring, Blink, Nest, n some china thing to test the software and features. picture quality especially at night, and watching the auto-tracking follow a mouse a cross my lawn is cool. Just find Ring to have more of the features I prefer, my point is none of my electronics are used much. Picture is color in 4k even at night. has Light and microphone and speaker for 2-way communication, or scaring someone. Cameras mount in seconds if you able to use a power drill for 1 screw or a hammer. the camera can be placed at any angle due to the movement is magnetic. Very simple. The Magnet pieces that hold on 1 screw/nail can be moved without having to do anything but grab the camera and see if it works better. 30 min you can try the whole yard. well mines 3 acres.
