Another vote for Blue Iris here.
The max framerate of that Swann bundle you posted is 15 (and note that it says "up to," which makes me suspect the NVR will choke if you put more than one or two cameras on it, and your actual FPS will be lower), which is half the framerate that would be considered full motion.
is a decent example of the difference between 15 and 30 fps. Personally I would not want anything less than 30 for my security cameras - if whoever is committing a crime against you moves fast enough at 15fps, it's possible there will be no frames in which their face is recognizable.
I also stay away from wifi cameras because interference can render them useless at the wrong time. If interference is enough to disconnect them from your router, or if your router isn't one of the expensive long range ones and the camera has a couple of walls between it and the router, you will get signal drops.
The one wifi camera I have on my setup, which is only there because it's not monitoring an area likely to be invaded and it was free, used to drop out all the time until I spent $200 getting a good router.
