General room guidelines

The physical conditions

When building a video meeting room, or using an existing room for
video meetings there are a few guidelines to consider.
Lighting
•
The illumination should be distributed evenly in the room to obtain
low contrast
•
The ideal light intensity is a little higher than in an ordinary meeting
room. Typically, the luminous intensity should be 800–1400Lux,
measured at the table with an incident light meter
Seating area and table
•
The seating area and table should be non-shiny and non-patterned
•
The seating area should allow all participants to see the monitor
Walls
•
The color of the wall should be in good contrast to skin tonality
Light blue is a complementary color to skin tonality, it gives a good
contrast and is commonly used
•
Acoustically reflective surfaces (such as glass or concrete) should be
covered with curtains or sound treatment
Audio
•
The Noise Floor (the sum of all the noise sources) should be less
than max 35dBA
•
The reverberation time should be 0,3 to 0,5 seconds
Ventilation
•
The requirements for ventilation may be a little higher than in an
ordinary meeting room.
•
Keep in mind the Noise Floor (see Audio)
•
Velocity creates noise, therefore keep velocity of air low

The room equipment

When placing and using the room equipment there are a few
recommendations and guidelines to consider.
The microphone
•
The microphones should be evenly distributed on the table. Avoid
positions where they can be hidden behind obstacles like laptop,
projector or other equipment placed on the table
•
Do not place a microphone close to noisy equipment like computer
and projector fans, power outlets or similar arrangements on the
table. The microphone will pick up noise from these arrangements
quite strongly.
The camera
•
The camera should be able to "see" all participants in the room. Use
the pan, tilt and zoom features to adjust the picture.
The PC
•
PC's placed on the table should not cover the microphones as this
will reduce the audio quality at the far end
Position of the system
•
Position the video system in such a way that all participants
attending the meeting are visible to the far end.
•
If appropriate, the far end should be able to see people entering or
leaving the room
The document camera
•
The document camera should be close to the chair person or a
designated controller of the document camera for ease of use
•
Make sure this person is visible on screen while carry out the task
Other peripherals
•
Arrange all the peripherals so that the chair person can reach each
of them to point, change the display, DVD, and still be fully visible on
screen while carry out the task

Environmental considerations

This section explains how to carry out basic adjustments and simple
tests to ensure that you send and receive the best possible image and
audio quality when using your system.
Iris control and lighting
By default the system camera will use an automatic iris to compensate
for changes in lighting. In addition to this feature, you may further assist
the system to maintain the best possible image quality by paying special
attention to environmental lighting and background colors as described
below.
Remember the system will send live images of both yourself and your
immediate surroundings.
•
Avoid direct sunlight on the subject matter i.e. yourself, the
background or onto the camera lens as this will create harsh
contrasts
•
Avoid placing the seatings in front of a window with natural daylight,
as this will make the faces of people very dark
•
If light levels are too low you may need to consider using artificial
lighting. As described above, direct illumination of the subject matter
and camera lens should be avoided
•
When using artificial lighting, daylight type lamps will produce the
most effective results. Avoid colored lighting
•
Indirect light from shaded sources or reflected light from pale walls
often produces excellent results
•
Avoid harsh side lighting or strong light from above. Strong sunlight
from a window or skylight may put part or all of the subject matter in
shadow or cause silhouetting
Loudspeaker volume
The audio system will use the Digital Natural Audio Module (DNAM)
which is integrated in the system. The volume of the audio is controlled
by the Volume key on the remote control.
