The camera has to be attached to a computer that downloaded skype and set up an account and is calling another computer that has a skype account. Then you ‘call’ the other computer and press the video call button. It has to be a good computer though or the video will make the program freeze.
Syag, it probably depends on your video card. You need a lot of RAM to use video on Skype and streamline an event like this. The older video cards don’t work so quickly, that’s why they freeze.
