VISION 5000 Videoconferencing System

Installation

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 Vision 5000.

Iris control and lighting

By default the Vision 5000 camera will use an automatic iris to compensate for changes in lighting. In addition to this feature you may further assist the Vision 5000 to maintain the best possible image quality by paying special attention to environmental lighting and background colours as described below. Remember the Vision 5000 will send live images of 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.  If light levels are too low you may need to consider using artificial lighting. As above avoid direct

illumination of the subject matter and camera lens.  When using artificial lighting, daylight type lamps will produce the most effective results. Avoid

coloured 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, for example: strong sunlight from a window or

skylight, as this may put part or all of the subject matter in shadow or cause silhouetting.  If you still have problems with the iris and lighting, manual adjustment of the camera parameters might

help - see Camera adjustments in Video Input menu.  Dim scenes can also be improved by manually adjusting the camera brightness setting.

Background

The appearance of the picture background is very important but easily overlooked. It is important to remember that the camera also shows whats behind you when in a videoconference. To ensure a suitable background we recommend you consider the following:

 Use a neutrally coloured background with a medium contrast and a soft texture, e.g. a plain curtain with

no heavy patterns or strong colours that may adversely tint the whole scene.

VISION 5000 Videoconferencing SystemInstallation

 Avoid moving backgrounds, for example: curtains in a draught, moving objects, or people walking behind

you, as this may both reduce image quality and distract the attention of the calling party.  Do not place the camera facing a doorway.

Brightness control

For adjusting brightness, colours or other settings of the TV monitor, you must use the TV monitors own remote control. Adjust the TV monitor to suit the conditions of the conference room.

The TV monitor has an on-screen menu and is very easy to use. For more information on configuring the TV monitor refer to the user manual for that unit.

Loudspeaker volume

The audio system will use the loudspeakers built into the TV monitor or the Natural Audio module (if installed). The volume of the audio system is controlled by the Volume Control keys on the Vision 5000 handheld remote control.

The default volume level can be set by adjusting the volume on the TV monitor using the TV monitors own remote control.

Guidelines for setting up videoconferencing rooms

The following are a set of guidelines to consider when either building a video conferencing 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 ½ of that measured at table, Max ¾ of

that measured at table.

- Colour 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:

- Colour: Depends on participants skin tones, cameras, and lighting.

Generally high contrast colour 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.

- 40 W (137 BTU/HR) for each Fluorescent tube (maybe).

- 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

VISION 5000 Videoconferencing SystemInstallation

How to prepare a typical room for videoconferencing

The diagram below shows a typical room designed to obtain the best results when using the Vision 5000.

The microphone should be placed at the front of the table to ensure that all speech will be detected. The best position for the microphone is at least 2 meters (6.5 feet) in front of the Vision 5000 on a plain, flat table with at least 0.3 meters (12 inches) of table in front of the microphone.

The document camera should be close to the leader or a designated controller of the document camera for ease of use. (Remember to arrange all the peripherals so that one participant can reach each of them to point, change the display, tape, and so forth).

The camera supports up to 15 pre-stored camera positions. The illustration shows three possible camera positions. One of all the participants, one of the whiteboard and one of the main speaker. The remaining presets are then available for other peripheral equipment, for example: a VCR.

Position the Vision 5000 in such a way as to avoid the possibility of somebody inadvertently walking into the cameras field of view when entering the room. Other than the conference participants there should be no moving items in the sent image.

System start-up

Your Vision 5000 should be in standby mode, if so pressing any key will wake up the system.

If the Vision 5000 does not respond: turn on the system by using the On/Off switch located at the rear of the Codec, see figure below. After a few seconds you should see a start-up message on the monitor.

If this does not help, check if your monitor is switched on. To switch your monitor on you normally push the power button in front of the monitor (depending on monitor type).
