Backlight
Compensation
Specifies whether to have the camera automatically
adjust for a bright background. Backlight compensation
is best used in situations where the subject appears
darker than the background.
Enabling this setting helps to relieve a bright
background, which can impact the tracking performance
of the Polycom EagleEye Director.
Primary Camera Specifies which camera is the main camera. The
primary camera is active when the Polycom HDX
system powers up. Its source is automatically set to
People.
Changing this setting causes the system to restart. After
the system restarts, you might need to select Detect
Camera.
Camera Pan Direction Specifies the direction the camera moves when using
the arrow buttons on the remote control.
Quality Preference Specifies the bandwidth split for People and Content
video.
•People
—10% Content, 90% People
•Both
—50% Content, 50% People
• Content
—90% Content, 10% People
Notes: In a multipoint call, the MCU setting determines
the People and Content video rates, not the system
sending the content.
This setting does not apply if Dynamic People/Content
Bandwidth is enabled or automatic bandwidth
adjustment is enabled using the API.
This setting applies only to calls of 128 kbps of higher.
Dynamic
People/Content
Bandwidth
Specifies whether the system automatically adjusts the
bandwidth allocation for people and content in
point-to-point H.323 and SIP calls. This setting
maintains equal image quality for People and Content in
the call.
Power Frequency Specifies the power line frequency for your system.
In most cases, the system defaults to the correct power
line frequency, based on the video standard used in the
country where the system is located. This setting allows
you to adapt the system in areas where the power line
frequency does not match the video standard used. You
may need to change this setting to avoid flicker from the
fluorescent lights in your conference room.
