After you install Horizon Agent with Real-Time Audio-Video, the feature works on your remote sessions without any further configuration. The default values for the webcam frame rate and image resolution are recommended for most standard devices and applications.
You can configure group policy settings to change these default values to adapt to particular applications, webcams, or environments. You can also set a policy to disable or enable the feature. An ADMX template file enables you to install Real-Time Audio-Video group policy settings on your Active Directory server or on individual desktops. See Configuring Real-Time Audio-Video Group Policy Settings.
If users have multiple webcams and audio input devices built in or connected to their client computers, you might need to configure preferred webcams and audio input devices to be redirected. See Selecting Preferred Webcams and Microphones.
When webcam images and audio input are redirected to a remote session, you cannot access the webcam and audio devices on the local computer. Conversely, when these devices are in use on the local computer, you cannot access them on the remote session.
