Note
This feature can be disabled for general users (see Creating or modifying a general user account) and for guest users (see Changing the features available to guest users).
By default the camera’s microphone is automatically muted when the lens is panning or tilting. You can change this setting if desired, as well as adjust the sensitivity of the microphone (see 5.6 Changing Audio Settings).
The audio may be interrupted or delayed due to your PC’s performance, the network environment, if you are running other applications, or if you have multiple windows open. Close other applications and windows or reduce the maximum bandwidth (see 5.1.1 Network (IPv4) Settings or 10.3 Configuring Your Camera for IPv6) for best performance.
When the image is refreshed (such as during preset registration or when clicking your browser’s refresh button), the volume is reset to the center position and the mute will be turned off (i.e., audio will be heard again).
