Solve : using external webcam at a distance?

1.	Solve : using external webcam at a distance?
Answer» i NEED a clip on webcam that will still give good quality video & stills even if I'm 2 to 3 meters away & MIGHT be MOVING around. i'll be using it for skype/video-chatting & possibly making movies for YouTube etc. i've only ever used built-in webcams on laptops. So, what do i need to look for in an external cam? HD? higher megapixel rating? anything else? any HELP or advice much appreciated thanks in advance
