each second of recording. Obviously, some stream quality is lost when lower quality settings are used. All three
standard quality settings produce recordings in SIF size when the unit’s video resolution is VGA and recordings in
CIF size when the video resolution is D1 (see
Video Resolution , page 18). High quality is the optimal recording
configuration, and is recommended for use whenever possible. For information about the framerates and bitrates
used for the standard quality levels, see
Advanced Recorder Settings , page 106.
NOTE:
If SVMultiClient is used to view live video-streams from a camera, the quality settings selected for
recording are also used for streaming live video the SVMultiClient at the highest-quality level. Thus, if
a camera is configured to record video at a high bit rate, and SVMultiClient operators also play live
video streams from the Video Gateway at highest quality, the total amount of data sent over the
network to SVMultiClient can be considerable. Depending on the package supplied by your internet
service supplier, this may result in high bills for internet services, especially if live video is transmitted
over the cellular network. To prevent such high fees, it may be advisable to set SVMultiClient’s default
quality level for live video streaming to medium or lowest. For additional information, please refer to
the
SVMultiClient User Guide .

2. Under Recording Quality , select the recording quality ( High , Medium , or Low ).
Note: For information about the data rates represented by the standard quality levels and about selecting
custom recording quality settings, see Advanced Recorder Settings , page 106.
Note: The percentage of available recording space that is allocated to the camera is indicated in the screen. (In
the illustration above, 24% is allocated to the camera.) This value is set in the Advanced Settings. For
additional information, see
Advanced Recorder Settings , page 106.
3. If the recorder is event-triggered, select the triggers that will cause the recording to start:



VMD: If VMD is enabled for the camera (see Video Motion Detection (VMD) , page 96), and you want
VMD events to trigger event recording, select VMD .
