Yes, presenters can decide whether or not to share their video with their audience. This can be controlled by a single click of the video icon in the webinar UI. Zoho Webinar protects the privacy of its users by keeping the camera disabled by default. This ensures that the video of the presenter is not shared without their permission. 

If you are the administrator of your organization, you can also control use of web cameras by your organization members across all webinars they conduct using Zoho Webinar.

With Zoho Webinar, you can share your entire screen or an application window you choose, with your webinar audience. You can also share your presentation from a connected monitor without sharing the screen you use to run your webinar. 

To share your screen, use the Start sharing option on the left menu of your webinar window. Learn more about screen sharing.

 

You can use computer audio (VoIP) or phone audio for your webinars. If your internet connectivity is poor, you may not be able to use computer audio smoothly. In these situations, you can use Zoho Webinar's list of dial-in numbers to join webinars through your desk phone or mobile phone. Dial the number for your region and enter the access code for the webinar as instructed. Your attendees can also use this facility if they are unable to use VoIP. However, they will incur charges for using their phone network.

 

If you would like to enable your attendees to join webinars through their phone without incurring network charges, you can purchase the toll-free add-on for Zoho Webinar. This add-on offers more than 55 toll-free numbers for different countries. Your attendees can use these numbers to join webinars from any part of the world without paying phone network charges.
