Hardware

Any CPU/GPU that supports VP9 hardware accelerated decoding. For desktop devices this is 6th Generation Intel® Core™ processors or newer. Android devices built post-2017 should be compatible.

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.

Firewall rules

You can find the Flexbox Video Stream IP in the Firewall rules for your Flexbox.
