Network
The ClearView Flex system streams video at three quality levels, please ensure you discuss with your Attendees the most appropriate quality for the connection. When presenting from your ClearView Flex Box we recommend you use a wired connection.
For a mobile Attendee connection we recommend the low quality stream. The network bandwidths we recommend are:
At least 3 Mbps for low quality, recommended for use when any of the Attendees are on a mobile connection.
At least 10 Mbps for medium quality.
At least 20 Mbps for high quality when you are sure all the Attendees have access to higher bandwidth and there will not be conflict for network resources.
