My wife just expressed interest in them. Anyone can tell us how they work. How does the cam transfer the recording to your computer? Or do you have to transfer only to video (that would seem to suck, giving only 2-4 hours of quality video) ? Which products are the best? Any and all explanations, tutorials and links would be appreciated. When the wife is feeling kinky I gotta jump before the window passes and the timid side returns! Thanks.
