*NO* camera? Even a simple webcam or a cellphone camera can be used to film video. Or a video camera with a video digitizer.
EDIT: You can get USB web cams on ebay (Buy It Now) price for less that $4USD (including shipping). I have used web cams for filming demos before. You may have to open the case to adjust the focus for closeups on some cheap web cams though...
