Adjusting Secondary Stream Quality
DW Spectrum's architecture provides significant CPU and network bandwidth savings by acquiring
multiple streams from a single camera: High Resolution (regular) and Low Resolution (approximately x10
less bandwidth). The second stream is always decoded by Media Server and is used for the following:
Software Motion Detection
CPU and Bandwidth Saving during Playback (RADASS)
The quality of the second stream is set automatically, however, it is possible for User to adjust the quality
of the stream.
IMPORTANT. Higher quality of the second stream provides for a much better look and feel (especially
on larger monitors), but can significantly increase CPU load on Media Server. It is not recommended to
change these settings.
To adjust the quality of the second stream:
1. Open Camera Settings and go to Expert.
2. Check I have read the manual and understand the risks.
3. Adjust Secondary stream quality.
4. Click Apply or OK when finished. To discard changes, click Cancel.
Note: If Camera does not support dual-streaming, the above settings are unavailable.
