Video doesn't have to be "on" a desktop today as most of it can be accessed thru the cloud using your Chrome, Firefox or IE browser and a USB camera. Depending on the size of your company and their security standards - Zoom is a nice option and they have a "free" service with some limitations. The website is www.zoom.us.com
If you need a more robust or enterprise level solution, Webex and Microsoft Teams would be the way to go and I can talk to you about those options.
Thanks
