I want to installed an outdoor camera system that is motion activated and maybe p2p compatible for easy access from outside the network. Basically I am just looking for something to record movement when a car enters the driveway, something moves in the yard, or the UPS guy shows up and have access to at least 1 stream remotely at 720p (at least 10FPS) There are a bunch of these 4channel 720p wireless camera systems with an NVR for around $150 but there aren't many in depth and informed reviews on them. Will I be disappointed picking up one of the cheap generic systems?

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.
