Zoom works with all common web browsers and runs on most common operating systems (Windows and MacOS are preferred).
Audio and video recommendations for both hosts and participants in a Zoom meeting:
Audio: Headset (with microphone) or a combined tabletop microphone and speaker (preferably with echo cancelling)
Video: Webcamera or HD-webcamera - built-in or USB plugin
