Note
• Talk button and Listen button cannot be used simultaneously. Talk feature is
stopped during listening. Talk feature can be used only for a user. Listen
feature can be used for maximum 10 users. If the audio is interrupted, reduce
the max. bandwidth (see page
51 and page 56). In this case, the number of
users for listening are reduced.
• Audio features such as camera microphone sensitivity and mute during pan/tilt
can be set up on the Audio page (see page
86).
• 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
51 and page 56).
• 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.
• Talk feature cannot be used from a PC when the camera is accessed via a
proxy server.
• If you cannot listen to the audio or talk from your PC, see page 14 of the
Troubleshooting manual (for BB-HCM311) or page 54 of the Installation/
Troubleshooting manual (for BB-HCM331) on the Setup CD-ROM.
• 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.
• [For BB-HCM331] If you install the camera outdoors, external microphone or
external speaker must be outdoor compatible.
