How do I make high quality video calls?
Logitech webcamThere are a couple of technical bits and bobs you’ll need to have before you can start making high quality video calls. Firstly, you’ll need a webcam that can take high quality video. Secondly, these video calls will require a dual-core processor in your computer. Lastly, high quality video calls require sufficient bandwidth (we recommend 380kb and above). 
Don’t try this on dial-up folks 😉
