Zoom will detect any video sources (like a built-in or USB webcam) and will attempt to use your default device when joining or hosting meetings. However sometimes you may not want video enabled, or you may have more than one viable video source.
While attending or hosting a Zoom meeting you can adjust which camera you are using by clicking the small arrow next to “Start Video”, found in the lower left corner of the Zoom taskbar. This will pull up a list of possible video sources with a checkmark next to the currently active device. Simply click on one of those devices to make it active. To toggle the video feed on or off just click the camera icon rather than clicking the associated arrow–a red slash over the camera icon indicates the camera is currently disabled. If no video options are listed try unplugging your webcam and plugging it back in–if that doesn’t work, please contact the Helpdesk for additional troubleshooting.
You can also click the “Video Settings…” option to bring up additional video options, including HD and low light adjustments.
