Audio Quality
These suggestions may enhance the audio quality in the room where the system is installed:
Carpet the floor.
Cover windows with curtains.
Position microphones away from sources of noise.
Place microphones at least five feet apart.
Note: Note: Note: Note: If you have ever held a conversation in an empty warehouse with concrete floors
and can remember the way voices sound in that environment, compare that to a
conversation held in a quiet, carpeted home with soft furniture, carpeting and curtains.
The importance of sound deadening techniques to improve audio quality will become
obvious.
Video Quality
To enhance visual quality, cover windows or select a room without windows in order to decrease
glare. Keep the room well lit to avoid dark areas in the camera view.
The decor of the room should be unobtrusive. For example:
Use a light, neutral color on the walls.
Do not use fine patterns, weaves, or wood grain in the background.
Do not place distracting objects in the field of view.
Use light, non-reflective tabletops.
System Location
Requirements
When selecting a location for the system, keep these requirements in mind:
The system must be located near a network connection and a grounded, three-pronged
power outlet. For the United States and Canada, this means a NEMA 5-15R outlet for 115-
volt AC or a NEMA 6-15R outlet for 230-volt AC. For other regions, this means a grounded
three-pronged power outlet approved by the electrical code of the region.
The area around the system must be clean and dust-free.
The area must be well ventilated and away from sources of heat, including direct sunlight.
The system must not be near sources of vibration or physical shock.
The system must be isolated from strong electromagnetic fields produced by electrical
devices (such as air conditioners, large fans, large electric motors, radio and TV
transmitters, and high-frequency security devices).
