Remote
Audio Monitoring
Current Video Server PCs include up to 5
audio inputs, allowing some camera(s) to have
sound included with the camera image (and in
associated video recordings). These sounds
can also be monitored at the Video Server PC
and at any authorized remote stations.
Multimedia Settings: Listening to audio through a
microphone is subject to Windows multimedia
settings for recording and playback (mute, volume,
etc.). Remote Stations must be equipped with a
sound card (or equivalent) and speakers. (A sound
card is already built into Video Servers.)
Audio Recording: Audio is not recorded as a
separate file. Instead, it is included in any local or
remotely recorded AVI (or MPEG) files for the
specific camera.
Legal Notice: The recording of live audio is subject
to local bylaws. Be sure to find out if audio
recording is restricted in your area before
proceeding.
16.7.1
Network / Connection Set Up

address).

16.7.2
Microphone and Speakers
Connect the microphone and speakers to the
appropriate/correct jacks on the back of the
Video Server. Bare microphones to connect to
through a line-level audio input (video capture
board or audio input board) will each require a
suitable pre-amp.

Push Button: The microphone can have a
direct/permanent connection, or it can be controlled
through a push-button or switch (e.g., for a one-way
A/V intercom application).

Since all sounds handled by the Video
Server's sound card will be heard at
the remote stations, it is best to turn
off
the sounds associated with MS
Windows (at the Video Server).
