If you have multiple cameras set up on your computer, you can choose which one to use when you log in to your space. To do this, go to the welcome screen of your space by accessing the space URL or leaving the space if you are already inside. On the first screen, you will be able to select your profile picture, name, and description. Once you click the "Continue" button, you will be taken to the device setup screen where you can make your camera selection.
On the second screen, you will find buttons for selecting your desired camera and microphone. Simply click on the buttons to choose the camera and microphone that you want to use.
To use a specific camera or microphone, simply click on the corresponding button on the second screen. Please note that you cannot change the speaker in this way. If you want to change your speaker, you will need to change the default speaker for your entire computer.
