Good evening kids! I have a question, that I believe I know the answer to, but want to re-confirm.Good evening kids! I have a question, that I believe I know the answer to, but want to re-confirm. The Arlo Pro 2 cameras are able to be added on to the current Arlo Pro base? We have moved and the house is larger than my last, so I have 3 more cameras to add to my current subscription and since the Pro (1) series are clearanced/discontinued, I want to add a few without having to purchase a whole new system I am also open to experience and comments with the newer systems and whether it would be worth utilizing a 720p in not so heavily trafficked areas and utilizing a 4k system in my high traffic areas and any interference between the two
