You will need to install some video chat software. Please find out which network your friends are using such as Skype (Windows/Mac), AIM (Windows only), FaceTime (Mac only), Google Hangouts (Windows/Mac) or Yahoo! Messenger (Windows/Mac). Download the corresponding software from the network's website and follow their setup instructions. Make sure you set HUE as both your camera and microphone in the new program's settings. Additional help on using a specific network can be found on each company's website.
