If a client computer has more than one webcam and microphone, you can configure a preferred webcam and microphone that Real-Time Audio-Video redirects to the remote desktop or published application. These devices can be built in or connected to the client computer.

Real-Time Audio-Video redirects the preferred webcam if it is available. If the preferred webcam is not available, Real-Time Audio-Video uses the first webcam that is provided by system enumeration.

Windows client computer
For a published desktop or published application, if the client computer has Horizon Client for Windows 4.2 or later installed, you select a preferred webcam or microphone by configuring Real-Time Audio-Video settings in the Horizon Client Settings dialog box.
For a virtual desktop, if the client computer has Horizon Client for Windows 4.2 through 5.1 installed, you can select a preferred webcam or microphone by configuring Real-Time Audio-Video settings in the Horizon Client Settings dialog box. Beginning with Horizon Client for Windows 5.2 and Horizon Agent 7.10, the Real-Time Audio-Video feature can redirect more than one webcam and microphone to a virtual desktop and you do not select a preferred webcam or microphone.
With Horizon Client for Windows versions earlier than 4.2, you must modify registry settings to select a preferred webcam and use the Sound control in the Windows operating system to select a default microphone.
