Designing the Room
Select the appropriate EasyUSB devices based upon the
customer requirements and room layout.
Starting with the camera selection, what will you use for
video?
The ClearVIEW HD-USB PTZ camera has a USB connection
emulating a standard web camera to the PC with HD video
quality (720p) and full PTZ controls required for group
conferencing environments.
Now that you have the camera, what type of audio will you
need?
This is where The EasyTalk USB Audio products come in.
There are five products that make up the EasyTalk USB
product line: The EasyUSB Mixer/Amp, The EasyMic MicPOD,
EasyMic Ceiling MicPOD, Bose DS-16 Ceiling Speakers and the
EasyTalk Sound Bar.
Now that you have audio and video, how do you control it?

AV Design Rules
In order to obtain optimal audio and videoconferencing
performance within a room, a few key guidelines should be
followed.
For Audio
s
The designer needs to place the EasyMic in a location on the
table or in the ceiling that covers all the potential participants
in the room.
s
A minimum of four feet separation should be maintained
between any loudspeaker and the EasyMic devices.
s
The EasyMic MicPod has an optimal pick up radius of
approximately 12 feet. However, this may vary based upon room
acoustics.
s
Using simple acoustical treatments such as carpeting, window
shades, acoustical wall panels, or other physical absorbing
material reduces audio reflections on surfaces such as walls,
floors and ceilings.
s
In videoconferencing applications, the loudspeakers should be
placed near the LCD display.
For Video
s
Locate the camera or cameras while paying close attention to
viewing angles, lighting conditions, and site obstructions. Avoid
placing cameras near fluorescent lights or open windows. For
videoconferencing, an eye-to-eye aspect is desirable between
the local and far-end participants.
s
Know your field of view and optical zoom range of the PTZ
camera. Wide-end horizontal viewing angles of 58 to 70 degrees
is needed in videoconferencing group meeting rooms to make
sure all participants can be framed in the shot.
s
Use multiple PTZ cameras to cover large spaces. Don’t try
to cover large areas with a single PTZ Camera as this can
produce very busy camera movements that can distract far-
end participants. For corporate training rooms, always use a
minimum of two PTZ cameras, one for the instructor and one for
the students/audience.
Employing these simple guidelines in your room designs will
allow all participants within the conference an exceptional
user experience that is free of echoes, choppy audio, and
tunnel speech.
