The biggest difference between the Pro 3 and Pro 2 is the lack of built-in video cloud storage. While the Pro 2 and its predecessors came with 7-day continuous cloud backup, the 3 doesn't include video cloud storage without a $120/year plan. It wouldn't be such a problem, but the local storage available through the base station/smarthub is pretty much useless. To access this local storage it needs to be removed from the base station/smarthub and viewed on a computer etc. There is also no option to use NAS as a workaround as they are not supported. As the owner of Arlo, I've watched the company make its products less and less user-friendly while increasing costs. My guess is that spinning it off into its own company probably has something to do with it. If I could go back and choose a different option for my smart camera system, I probably would, but I have so many of their products I'm locked out.
