Panasonic BB-HCM331A operating instructions For Microphone, For Speaker, Extsp

Operating Instructions

•Audio features such as camera microphone sensitivity and mute during pan/tilt can be set up on the Audio page (see page 68).

•If you are running other applications or opening multiple windows, the audio may be interrupted or delayed.

•When the image is refreshed during any operation such as preset registration or a web browser refresh, the volume is reset to the default (midrange) position. Audio that was muted is enabled.

•The audio may be interrupted due to your PC's performance or network environment. Reduce the max. bandwidth (see page 40 and page 44).

•If the camera is accessed while the PC user visits other websites, the active microphone may pick up audio from the PC's speakers. Be careful with it.

•If you cannot listen to the audio or talk from your PC, see 2.5 Audio Problems in the Troubleshooting section of the Installation/Troubleshooting.

•If you use external microphone, excessive length or poor quality microphone cable can cause a degradation in audio quality.

•To talk to the camera from your PC, an external amplified speaker must be connected to the camera. The speaker connects to the camera with a stereo audio cable similar to that used by your PC. Though the connector is stereo, the audio is not.

•If you install the camera outdoors, external microphone or external speaker must be outdoor compatible.
