Video Preview is not supported when the Collaboration Server is in Ultra Secure Mode. For more information see Ultra Secure Mode.

Collaboration Server users can preview the video sent from the participant to the conference (MCU) and the video sent from the conference to the participant. It enables the Collaboration Server users to monitor the quality of the video sent and received by the participant and identify possible quality degradation.

The video preview is displayed in a separate window independent to the Collaboration Server Web Client. All Web Client functionality is enabled and conference and participant monitoring as well as all other user actions can be performed while the video preview window is open and active. Live video is shown in the preview window as long as the window is open. The preview window closes automatically when the conference ends or when participant disconnects from the conference. It can also be closed manually by the Collaboration Server user.

Video Preview Guidelines

Video Preview is supported in CP Conferencing Mode only.

Video preview is available for AVC participants. It is not available for SVC participants.

Video preview window size and resolution are adjusted to the resolution of the PC that displays the preview.

Video Preview of the video sent from the conference to the participant is shown according to the line rate and video parameters of the level threshold to which the participant is connected.
