Introduction

Getting started

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

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 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

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

Audio

The Noise Floor (the sum of all the noise sources) should be less than 44 dBC

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. Consult the specifications for the monitor for data about the energy consumption. The TANDBERG Codec C90 together with the TANDBERG PrecisionHD 1080p camera has the following specifications:

Max rating – 175 Watts

Normal operation – 110 Watts

Standby – 110 Watts

Keep in mind the Noise Floor (see Audio)

Velocity creates noise, therefore keep velocity of air low

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

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.
