Requirements and recommendations

Requirements for organizers

To set up and control the video conference:

  • Workstation computer / notebook / tablet (Windows, Mac, Unix) with web browser
    • With (as powerful as possible) a connection to the Internet
    • A wired connection is preferable to WLAN.
  • Valid UniAccount
    • Please note the different access conditions for the various services
    • Secondary accounts do not have host authorization for video conferencing
    • E-mail address (in the address area of ​​the University of Kassel) for sending the invitations and for communicating with the participants

Requirements for all participants

A terminal device for participating in the video conference

The video conferences can be accessed via various devices. The simplest option is access via the web browser of a standard workstation computer / notebook. Any client programs that may be required will then be loaded and installed automatically.

  • Workstation computer / notebook (Windows, Mac, Unix)
  • if necessary, classic video conference devices (connection via H.323 or SIP) - depending on the conference software used
  • Smartphones or tablets with the app for the conference software used (for Android or Apple operating systems)
  • Dial-in by phone

Audio-video equipment:

  • Web camera (mostly already built into notebooks, tablets and smartphones)
  • Microphone and speaker output
    • To avoid echoes and background noise, all participants (with the exception of video conference systems) should use a headset (headphones / earphones with microphone).

Connection to the Internet:

  • A powerful Internet connection is helpful for good video and audio quality
  • A wired connection is preferable to WLAN.
  • When used at home, poor connection quality can possibly be improved if other data-intensive Internet uses (e.g. video streaming by other household members) are paused for the duration of the conference.
  • The organizer should be given an email address to receive the invitation and, if necessary, to communicate with the participants.

Recommendations for organizing the conference:

  • Make sure the background is calm (and tidy)
    • Avoid moving elements in the background as much as possible (e.g. fan, fluttering curtains, people walking by, etc.)
  • Create a quiet environment during the conference
    • Close windows and doors to block out sources of noise
    • Avoid interference from visits, the phone or messenger
  • Make sure there is good lighting
    • Bright and glare-free lighting is ideal (indirect light from above and / or from the direction of the camera)
    • Avoid back light (windows in the back of the participant) and strong side lighting (participants are shown too dark).
    • Colored light or reflections from colored surfaces (e.g. furniture) can lead to unfavorable color distortions.
  • Maintain conversation discipline
    • Speak clearly at normal conversation volume and speed.
    • Depending on the transmission quality, there may be small delays in video and sound transmission. Talking at the same time therefore leads to mutual interference and confuses the participants.
    • If you want to say something, raise your hand, if necessary, or use the options built into the video conference clients to ask you to speak.
    • Switch your microphone to mute and only switch it on for the duration of your speech. In this way you avoid the transmission of annoying background noises to all participants.
