I've got Lorex Security Cameras on the outside of my house, all wired to a DVR in the attic - depending on your budget and your desires, these are the best vaule out there and their quality is hands down better than any of the streaming cameras out there. With that being said - there is work involved - running cables and all that.
Inside the house I have several Arlo 2 camera - I like them, the app is good, they integrate with SmartThings, and have good night vision. Can't go wrong with Arlo if this is what you are wanting to spend the money on. Easy setup and quick notifications.
I ordered a RingPro doorbell for my wife for Christmas - I'll post a review when I get it. We wanted the realtime 2 way audio so we can combine it with my smart door lock.
