Audio
When you configure video and recording (see "About video and recording configuration" on page 63)
for specific cameras, properties include the possibility of selecting a default microphone and/or
speaker for the camera. With a default microphone and/or speaker selected for a camera, audio from
the microphone and/or speaker is automatically used when you view video from the camera.
If a microphone/speaker is attached to the same hardware device as the camera, that particular
microphone/speaker is the camera's default microphone/speaker if you do not select otherwise.
Properties available in all XProtect software versions:
Name Description
Default Microphone
Select a default microphone.
Properties available in XProtect Enterprise and XProtect Professional only:
Default Speaker Select a default speaker.
The ability to select a default microphone or speaker for the camera is only available if at least one
microphone and/or speaker has been attached to a hardware device on the surveillance system.
Recording
The term recording means saving video and, if applicable, audio from a camera in the camera's
database on the surveillance system server. Video/audio is often saved only when there is a reason to
do so, for example as long as motion is detected, when an event occurs and until another event
occurs, or within a certain period of time.
When you configure video and recording (see "About video and recording configuration" on page 63)
for specific cameras, recording properties include:
Name Description
Always
Record whenever the camera is enabled (see "General" on page
81) and scheduled to be online (see "Online period" on page 129)
(the latter allows for time-based recording).
Never
Never record. Live video will be displayed, but —since no video is
kept in the database —users will not be able to play back video from
the camera.
Conditionally
Record when certain conditions are met. When you select this
option, specify required conditions (see the following) which
enables you to store recordings from periods preceding and
following detected motion and/or specified events.
Example: If you have defined that video should be stored when a
door is opened, being able to see what happened immediately prior
to the door being opened may also be important. Say you have
specified that video should be stored conditionally on event, with a
start event called Door Opened and a stop event called Door
Closed. With three seconds of pre-recording, video is recorded
from three seconds before Door Opened occurs and until Door
Closed occurs.
