Operational Considerations
Iris Control and Lighting
By default the HCS III camera will use an automatic iris to compensate for changes in lighting. In addition to
this feature you may further assist the HCS III to maintain the best possible image quality by paying special
attention to environmental lighting and background colours as described below. Remember the HCS III 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. Again, 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 the ‘Video Settings’ menu:
• If a subject is backlit, e.g. a person in front of a window, it will appear dark. This can be corrected by
switching on the backlight function (automatic on some cameras).
• Dim scenes can also be improved by manually adjusting the brightness.
Brightness Control
For adjusting brightness, colours or other adjustments of the monitor, you must use the controls monitor’s
front panel. Adjust the monitor to suit the conditions of the room. More adjustments can be made using the
on-screen menu. Refer to the monitor’s user manual for more information.
Loudspeaker Volume
The audio system uses the built-in high quality loudspeakers and amplifier specifically designed for this
system. The volume of the audio system is controlled by the volume control keys on the HCS III remote
control. The volume control on the monitor is not used.
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 neutral 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.
• 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.
