1. Room Design Considerations
When designing the room in which you are going to install a VidyoRoom, you should take a
number of factors into consideration, such as the placement of the windows, the noise level in the
room, the lighting, and so on. This chapter describes these factors and provides
recommendations to assist you in this process.
If your VidyoRoom is already installed and you simply need to configure the system, skip this
chapter and continue with the next chapter, 2. Configuring the System Using the Admin UI.
VidyoRoom Room Design Considerations
This section describes the factors you should consider when designing a room for your
VidyoRoom installation.
Selecting and Preparing the Room
Windows
Because windows create audio reverberation, less than 20% of the room should have windows or
other vertical glass walls. Also, natural light coming from windows varies considerably, which can
affect the quality of the video. Therefore, if your room does have windows, you should install
acoustical window treatments or blackout curtains.

1. Room Design Considerations

Flooring, Walls, and Ceilings
A room where the floor is carpeted, the walls are composed of drywall, and the ceiling is
suspended typically provides the best acoustics. Of course, you can select a room with different
surfaces (such as tile floors or concrete walls), but these are often more reverberant, and therefore,
may affect the sound quality.
A cost effective way to improve acoustics is to add carpeting or rugs if your floor is not carpeted.
You may also want to consider adding acoustical sound panels to the walls.
Noise and Temperature
When selecting the room in which to install your VidyoRoom, keep these noise and temperature
considerations in mind:
◼The room where the VidyoRoom is located must be equipped with Heating, Ventilation, and Air
Conditioning (HVAC) equipment. Remember, however, that HVAC equipment can raise the
noise level in the room.
◼You should consider which rooms are nearby and try to select a room that is not adjacent to
frequently noisy areas, such as cafeterias or reception areas.
Acoustics
The quality of the sound is just as important as the quality of the video. You want the dialogue
between participants to sound like everyone is in the same location, which means that you need
quality microphones placed in the right spots. You may choose to hang microphones from the
ceiling, embed them in the table, or place them on the table.
Microphones pick up sound reverberating off hard and flat surfaces in the room. You can dampen
reverberations by installing noise-dampening ceiling tiles, fabric-wrapped acoustical panels on the
walls, or a combination of both.
Room Color
The color of the walls within the camera field of view can impact how the far-end participants
perceive the video quality. If you want the far-end participants to see higher quality video, ensure
that the wall at which the camera is pointing is non-textured, non-patterned, and not reflective.
Painting the wall a muted color, such as beige or blue-gray, looks better on video than bright white
or dark colors. As a general rule of thumb, the brighter the room is, the darker the walls should be.
For example, if your room has no windows, dark carpeting, and the overhead lights are not
extremely bright, you should consider painting your walls a lighter shade, such as pale blue or light
beige. If, on the other hand, your room gets a lot of natural sunlight, has light-colored carpeting,
and has bright overhead lights, you should consider painting your walls a slightly darker shade,
such as tan or medium gray or blue.
If you want to test colors before painting the walls, try hanging fabric of various colors on the back
wall to see which color looks best on video.

Lighting
The room in which your VidyoRoom is located should have evenly dispersed, ambient lighting. For
the best lighting, use LED lights. Although the upfront cost for these is higher, the long-term cost is
lower. The direct fluorescent lighting that is common in offices is not recommended because it
causes harsh shadows on the faces of the participants. In addition, its brightness can vary
considerably at different parts of the room. If you cannot change the fluorescent fixtures, get full
spectrum bulbs designed for video.
The ideal color temperature should be between 3,000° and 3,500° Kelvin, and about 70 foot
candles of intensity at the subject.
Lighting for video can involve as many as four lighting positions (which are explained below), with
the Key Light being the most important. For most multi-purpose conference rooms, a strong color-
balanced Key Light supported by additional full spectrum lighting in the room will work well. Just
remember: you don't want meeting participants feeling like they're in a television studio.
Here is some additional information about the lighting positions:
◼Key Light: Light shining on the participant from the front. These lights are generally placed high
and at the center, or to each side of the seating area if two are required. Aim them downward
at a 45° angle to light the participants’ faces without causing their eyebrows to cast a shadow
over their eye-sockets.
◼Fill Light: Lights shining on the participant from the front, but placed at a low angle to soften
shadows under the eyes and chin.
◼Hair Light: Lights at the rear of the room, above the participants and aimed downward to help
separate the participants from the background.
◼Backdrop Lighting: Lights above and (if space allows) between the participants and the
background. Two lights are usually required, each aimed toward the opposite half of the
background to evenly light it.
In addition, always ensure that no lights are pointing in the camera lens, and avoid pointing any
lights directly at the displays. If possible, you may want to hire a lighting designer and have the
lighting professionally installed.
Vibration
Room or wall vibration can be caused by HVAC equipment, heavy machinery being used nearby,
trains passing by, and other factors. If the wall on which the camera and displays are located
vibrates excessively, the camera may also vibrate. This vibration may be noticeable by the far-end
participants. Therefore, if you have known vibration issues, consult the building manager or an
architect to determine the optimal placement for the camera.
Installing the VidyoRoom Equipment
Once you have selected and prepared your room, you can begin installing the VidyoRoom system.
For information about how to unpack and install the VidyoRoom, refer to the VidyoRoom Getting

Started Guide that was shipped with your VidyoRoom system. This guide also describes how to
configure the account and network settings after your VidyoRoom powers up.
Controlling the VidyoRoom
You can control the VidyoRoom using the hand-held infrared remote control or the hand-held radio
frequency remote control.
Alternatively, you can control your system using VidyoRemote 3 for iOS. VidyoRemote 3 is a native
iPad application for controlling VidyoRoom version 3.3.10 and later. It is available on the Apple®
