Guidelines for Optimal Videoconferencing Environments
The following are a set of guidelines to consider when either building a videoconferencing room, or
using an existing room for videoconferencing.
LIGHTING
- Low Contrast desired for light intensity.
- No dark spots.
- Intensity @ table 800 - 1400 Lux as measured
with an Incident light meter.
- Intensity @ back wall: minimum ˚ of that
measured at table, Max ∫ of that measured at
table.
- Color temperature: Depends upon wall color and
camera.
- Typically 3200 - 3600 degrees Kelvin
- Block sunlight from entering room.
SEATING AREA (TABLE)
- Should allow all participants to see Monitors.
- Should allow camera to "see" all participants.
- Should allow participants to see each other.
- Should allow 3 linear feet for each participant.
- Non-shiny non-patterned preferably light grey
surface (if table used).
WALLS
- Color: Depends on participants skin tones,
cameras, and lighting. Generally high contrast
color desired . Light blue is commonly used.
- Acoustically reflective surfaces (such as glass or
concrete) should be covered with curtains or
sound treatment.
AUDIO
- Noise Floor Maximum 50dBC.
- Noise Floor preferred less than 44dBC.
- Reverb Time .3 to .5 sec.
- Absorption Coefficient .25 to .45.
- No flutter echoes.
VENTILATION
- Keep in mind Noise Floor.
- 300W (1024 BTU/HR) per person.
- 400W (1365 BTU/HR) for equipment.
- Intake and exhaust should be located near
equipment.
- Velocity = Noise. Therefore keep velocity of air
low.
MONITOR SIZE
- Optimal distance from monitor for viewing people
is about 7.5 x monitor size.
- Optimal distance from monitor for viewing
documents is about 3.25 x monitor size.
- Viewing Angle: 45 degrees off axis maximum.
ROOM
- Should be located away from noise
- Should not have windows
- Doors should be located off camera - A "diamond"
shape gives best viewing angles, camera
angles, and can seat the most people.
