General Advice

The audio is the most important aspect of a video conference. And audio is primarily affected by the room, number of people and microphone (even built-in laptop speakers tend to be good enough). A large seminar room with two people in it using a laptop is one of the worst situations. Why? There will be lots of echo because of the large amount of sound reflective surface (walls, tables) and the lack of sound absorbing objects such as people and soft furnishings (e.g. curtains, carpet). And not using an echo-cancelling microphone.
For one-to-one a headset is going to work very well. For a small group of people use an office or small seminar room together with an echo-cancelling microphone (from IT Support). For a large number of people a microphone system will be needed - please ask IT Support.

Specialist Equipment Available

In both Hannover and Potsdam the IT Department has specialist equipment available for video conferencing including microphone systems for larger rooms and cameras that can record chalk-boarding.
