•Low, Med, and High quality settings -- allow you to specify the amount of detail in the transmitted video. High quality transmits the most detailed images, but at the expense of CPU and network bandwidth. The use of Custom quality settings is strongly discouraged unless you are highly knowledgeable. Note that the two clients in a video call negotiate to a common video quality that is acceptable to both, so delivered image quality may vary from call to call.

Note: There is no tool or formula that allows you to compute the network bandwidth (in bits per second) for an arbitrary combination of video settings. However, network bandwidth increases with increasing quality.

•Format button -- produces another window that allows you to specify the size and internal organization of the video image. The window typically appears as shown in the following figures. This window will vary from camera to camera.
