thats not really a problem these days. storage really is only an issue when you start getting into huge number of cameras or megapixel cameras.
those cheap cmos are ok if the light doesn't change to rapidly and its fairly even light. low res is not bad if you have a small area. so still quite suitable for something like a doorway, or a hallway where subject is forced to walk in a set area.
don't forget camera systems are pointless if they can't identify the person and with budget cameras they have to be close.
i'm not a big fan of wireless cameras. you have to wire up power to them anyway so its not a problem to run a video cable. wireless also can cop interference as a lot of other devices use that same frequency ie you can end up recording your neighbours reversing camera, baby monitor etc.
i see you can wire cat5 to that camera so you don't need a wireless receiver. being IP you don't need to buy a separate DVR card, so it make for a simple install.
