Camera Issues
How to adjust room lighting?
You can alter the environmental lighting and background colors of your environment to obtain
the best video quality. If light levels are too low you may consider adding artificial lighting.
Reflected light from pale walls often produces excellent results.
Avoid the following situations:
Direct sunlight on the display device, the background, or the camera lens which creates
harsh contrasts.
Colored lighting.
Why can’t I adjust the camera angle and focus?
You can adjust the camera when the endpoint is idle or during a call. The camera cannot be
adjusted when the endpoint is in the menu screen.
Ensure that the batteries in the remote control are in good working condition, and installed
correctly.
Aim the remote control at the sensor when you perform a task.
Ensure that no objects are obstructing the sensor on the front of the camera.
Ensure that the LED on the front of the camera flashes green when you use the remote
control to perform a task.
Ensure that what you are controlling is the local camera.
Reboot the endpoint.
If the above suggestions cannot solve your problem, perhaps the remote control is broken.
You can contact your system administrator for help.
Why is the video quality bad?
Ensure that the display device has suitable resolution.
Check whether the packet has been lost. For more information on packet loss, refer to Call
