We generally order webcams as needed rather than have them here in stock. The camera we officially support and order is the Logitech QuickCam Pro 9000.
Our main webcam use is for audio/video recordings for online course material and web-conferencing through WATTLE.
The webcams can also be used for Skype. Every machine at the ANU College of Law has the ability to use Skype, whether you have a webcam or not. However, to make video calls you will need to have a webcam, which you can ask the IT & C Unit for.
