Firstly, you will need a webcam. You can use Skype with most webcams currently available, or you can purchase one that’s guaranteed to work seamlessly with Skype from the Skype shop.
To set up video, you’ll need the latest version of Skype for Windows or Skype for Mac. The first time you run Skype with a webcam installed, you will be taken through a few screens to help you get up and running.
You can also activate video by going to:
Tools > Options > General > Video Settings
