N You can adjust frame rates from 1 fps up to a maximum of 25 fps and resolution up to a maximum of
1920x1080. A high resolution at a fast frame rate might not be supported on all devices or in all

Configure a Preferred Webcam or Microphone on a Mac Client System
With the Real-Time Audio-Video feature, if you have multiple webcams or microphones on the client
system, only one webcam and one microphone can be used on the remote desktop. You specify which
webcam and microphone are preferred at the command line by using the Mac defaults system.
With the Real-Time Audio-Video feature, webcams, audio input devices, and audio output devices work
without requiring USB redirection, and the amount of network bandwidth required is greatly reduced.
Analog audio input devices are also supported.
In most environments, there is no need to congure a preferred microphone or webcam. If you do not set a
preferred microphone, remote desktops use the default audio device set in the client system's System
Preferences. See “Select a Default Microphone on a Mac Client System,” on page 56. If you do not congure
a preferred webcam, the remote desktop selects the webcam by enumeration.
