8.18. How many attendees can use their camera at the same time? Are there any limitations?

All the attendees of the session can use their cameras at the same time.
For example, if there are 50 attendees in a session all can turn on their respective cameras during the session.
The only limitations are the users own bandwidth. Onstream Webinars will allow you to start as many video streams as you like but performance may suffer if bandwidth isn’t available.
