Selecting and Adjusting a Camera
The LifeSize remote control operates pan, tilt, and zoom functions for adjusting the camera:
• Left and right arrows to pan
• Up and down arrows to tilt
• Zoom in and zoom out keys to zoom
A camera icon displays in the input window for the camera you are controlling when using
these functions. For example, an icon inside the picture-in-picture window indicates control
of the primary (near) input. To adjust the camera before a call, press Near and then adjust
the camera.
Far End Camera Control
You can control the far end camera if it is enabled properly. Far end camera control works
only when you are in a call and the far end side supports Annex Q. You control a far end
camera in the same manner as you would control a near end camera. To select which
camera to control during a call, press the Far button twice and then press the
select the camera you wish to control.
To prevent far end users from controlling your near end camera, see your administrator (or
refer to "Configuring Video Behaviors" on page 28).
Managing Video Call Quality
LifeSize Room systems are based on the latest H.264 standard and provide support for
H.263 for interoperability with all standards-based video communications systems.
The system automatically selects the best video algorithm based on the video source and
capabilities of the remote system.

LifeSize Codec
The LifeSize codec compresses outgoing video, audio, and data, transmits this information
to the far end, and decompresses incoming information. You should not need to interact with
the codec once it has been properly set up in your environment unless you are experiencing
problems. See your administrator for information about resetting or rebooting the codec and
its proper setup.
