Best practices
A successful video conference provides a face-to-face
meeting, even if the participants are miles or continents
apart. Keep in mind that it still is a meeting—normal
etiquette and dress code apply even here.
General
Consider setting the unit to Automatic Answer, but
mute the microphone for privacy reasons, if possible.
Do not forget to rehearse “the noble art of operating
a video system” to the extent needed.
In the meeting room
Make sure the microphone is placed at the front of the
table to ensure that all speech will be detected. The
best position is at least 2 m (6.5’) in front of the system,
on a at surface with at least 0.3 m (1’) of table in front.
Directive microphones should point away from the
video system.
Make sure that no speaking participant experience
obstacles blocking the view to the microphone at all
times.
Microphones should always be placed away from
noise sources like computer and projector fans
placed on the table. The noise from such sources is
often perceived as surprisingly loud by the remote
participants.
If you use a document camera try to arrange the
participants so that the camera is close to the leader of the
meeting, or alternatively, close to a designated controller.
Remember to arrange all the peripherals so that one
participant can reach each of them to point, change
the display, record or perform other functions during
the conference.
To help ensure the most natural meeting environment,
position the camera on the top center of the receiving
monitor, if possible. The camera should point directly
at the meeting participants to guarantee eye contact
with those at the far end. Check this out by means of
the self-view feature of your video system. The self-
view settings shows what the remote party can see
from you (the outgoing video).
If you are going to share content you are normally
going to make use of duo video. That implies the use
of two video streams, one showing the presentation
and the other showing the presenter—or the group
of presenters. Smaller systems may force you to
choose between showing the presentation or the
presenter.
For duo video some attention is needed. Duo video
is sometimes shown side–byside with half the
screen showing the presentation and the other half
showing the presenter. Provide the impression that
you seem to look towards the presentation instead of
the impression that you sit with your back towards it,
when all is viewed on the remote monitor. If in doubt,
look straight into the camera to avoid this situation.
Use camera presets
Cisco TelePresence systems let you create
predened zoom and camera pointing directions
(pan). Use these to zoom into the person speaking,
if appropriate. Do not forget to zoom out again
afterwards.
Loudspeaker volume
The audio system will use the loudspeakers built
into the monitor or the Cisco Digital Natural Audio
Module.
For some systems you can set the default volume
level by adjusting the volume on the monitor with the
monitor remote.
Brightness control
To adjust brightness, colors or other settings of
the monitor, use the monitors own remote control.
Adjust the monitor to suit the conditions of the
conference room. The monitors supplied by Cisco
have on-screen menus that are very easy to use.
For more information on conguring the monitor, see
the corresponding user manuals and administration
guides.
Ease of Use
To help meeting participants dial, add presentations
and use other functionality during a call, consider
stationing a poster, table tent or other quick-
reference guide in the room.
