It sounds like a scam, your spelling sux for a college student, use a spell checker, and the shift key wouldn't hurt. Should have learned that you should make your presentation look like you are serious, if expect people to take you seriously.
China turns out a bunch of tiny video recorders (camera+DVR). Have seen pens, buttons, keychain car alarm remote (got this one), small enough to hide in a pack of gum, cigarette lighters (no smoking in class), sunglasses. Battery only lasts an hour (claim two hours), and you won't know what you got, until you plug it in to the computer. Word of caution, when I plugged mine into my XP (no internet), my virus protection went crazy, formatted the camera, and seems all is well. Pretty good deal, for under $40, 4 gig storage, video (VGA) and still pictures(1280x760), and the image quality is clear in decent light, not useless in low light. Case seems pretty solid, doubt it'll break if dropped.
Sounds like you want to sell the videos, because I doubt many people want to sit through 3 hours, and your typing doesn't speak to highly of your interest in education...
