WIth the Arlo Pro 2, you can buy a second home base (connected via ethernet to an Orbi satellite closer to those cameras), and that works as “range extender” of sorts. In reality, you just have all your cameras and hubs in your Arlo account, and you can view them all together. You don’t need a mesh network, just a wired ethernet connection to the second (or 3rd, 4th, etc.) Home base. The second home base would have its own set of cameras, but you can look at all the cameras together on the app as if it were one system. I currently do this with 5 Arlo Pro 2 cameras (3 on one base station on one side of the house, and 2 on the other at the other side of the house). I know it is not an ideal solution, but the range stinks and there is not much you can do about it.
I just ordered my Eufy cameras, and they will be at opposite sides of a moderately large house. I wonder if you can buy a second Eufy Home Base (or, another camera with Home Base) and do the same thing. The Eufy app looks and appears to work just like the Arlo app, and you can add all sorts of devices. Presumably Eufy will have a doorbell, and other security devices soon. Ideally Eufy will have a reasonable range extender, but a second Home base may be a workaround if you can get an ethernet connection at this base.
I actually like the Arlo system, but I am moving and I am buying a new security camera system for the new house. I was considering the Ring system, but then decided on Eufy based on battery life (my Arlo’s would only last a week, so they are all hardwired now) and upcoming HomeKit support (in addition to Google and Alexa). To me Eufy appears to be Arlo on steroids (even in its admittedly current beta state).
