I'm a big fan of Unifi. We have all Unifi network switches, APs, and now cameras. We replaced our old camera system with Unifi. It's great! It loads fast, can be viewed from the browser, and it's crazy easy to add a camera. We currently have 16 and are adding 5 more and probably more down the road. With 16 cameras set to record on motion, and the 2TB Unfi video recorder/controller, we get almost exactly a month of footage before it writes over the earliest recordings. I'm an IT guy that wears a lot of hats, this is easy to manage for anyone.
