I install what the customer can afford. I have used pretty much every system out there bar none. Just stick with POE and never use wifi. It all depends what you are looking to do with them. The off brands won't last as long but some of them have decent picture quality. We even used a no name Zosi and while it wouldn't be my choice its still up and running almost 3 years later and they are satisfied with it. Its all in what kind of end result you are looking for.
