Thank you both for the replies.
I really don't want to run ethernet to the outside and drilling through the walls, but I understand what you're saying about PoE being simpler.
Why do you say wireless is unreliable?
I found a lot of people had congestion issues which caused connection problems but it sounded more like they just had no clue about wifi or networking and only wanted a plug and play magic system. I don't have any 2.4ghz congestion. All my 2.4ghz stuff channel hops or is set to be tolerant of my other wireless sources.
I currently have 2 cheap-o indoor ptz and 1 fixed ip camera but no nvr/dvr to record to, only their microsd cards and their ftp servers. I haven't had any issues with them so far.
