Hands Down, Nuvico.
Better over the internet. Can be used with a Dynamic IP address. The 15fps is over kill for what you are doing. The Nuvico will give you 7.5fps which is more than enough and because it records in MJPEG you get a superior image on recording.
I like the everfocus as well, but if you are giving me a choice I would chose the Nuvico.
