Video conferencing systems enable online communication and collaboration between participants. Basic functions of the systems are, in addition to audio and video transmission, the ability to share the screen, polling options as well as chat and note-taking functions.

Prerequisites for successful use

We recommend for participation in a video conference:

  • a powerful terminal device,
  • a headset,
  • a webcam,
  • a stable and fast internet connection,
  • no light source in the background

Despite similar basic functions, video conferencing systems differ in their operation. We therefore recommend that you familiarise yourself with the chosen system and its options in advance.

Our system comparisons and selection aids

Depending on the underlying scenario - from confidential consultation hours and seminars to conferences and public lectures with up to 300 participants - the requirements for videoconferencing differ in both technical and didactic requirements. Depending on the intended use, whiteboards, breakout rooms, the possibility of telephone dial-in, recording function or integration into the central learning platform Moodle are useful additional functions. When choosing a suitable video conferencing system, security, data protection, stability and scalability of the system are relevant.
