When logging into the Lifesize app for the first time, you have the option to select the camera and microphone to use for video conferencing calls and meetings.
If you have multiple camera options available to use with the Lifesize app, select the one that fits your needs best. To specify your camera preferences, select from the options in the Camera list. Use the video display to check the quality of your selection.
To specify your microphone preferences, select an option from the Audio list. You may choose to always start with your microphone muted.
Check your microphone by speaking into the microphone. As you speak into the microphone, a green bar shows on the volume meter if the microphone is picking up sound.
Check your speakers by clicking Play test sound and listening for a ringing sound.
You can also set these options at any time from Settings in the top right navigation menu.
