Rev. 072017 Page | 68
To disable automatic adjustment for all Cameras:
1. Disable recording for all cameras and close them (if opened for viewing).
2. For each Camera go to its Web Page and set desired image settings.
3. Open Main Menu and go to System Administration –> General tab.
4. Remove Allow system to optimize cameras settings flag.
5. Click OK when done or Cancel to discard changes.
This setting influences on the following ones:
 Adjustiung Average Bitrate on Device
 Adjusting Secondary Stream Quality.
Setting Up Camera Transport Protocol
Some cameras stream data in a different way. Usually 2 protocols are used for streaming: UDP (faster, but less
reliable) and TCP (more reliable, but slower). DW Spectrum tries to determine the best protocol for the camera.
However, sometimes camera may have issues when streaming via the chosen protocol. In this case setting the
protocol manually may help.
To do so:
1. Open Camera Settings and go to Expert.
2. Check I have read the manual and understand the risks.
3. Choose RTP Transport and click OK or Apply.
4. Restart the camera.
5. If the changes do not help, choose a different protocol and restart once more.
Forcing Software Motion Detection on Specific Stream
DW Spectrum provides the Software Motion Detection feature. It is performed on the Server side. Server analyzes
secondary stream from Camera and detects motion. For this purpose it needs to perform decoding. Thus, if the
secondary stream is high-resolution one, it may consume all the Server CPU.
Sometimes specific cameras report their configuration incorrectly and swap primary and secondary streams. Server
considers Hi-Res stream as a secondary-one and tries to decode it, resulting in high CPU load. To avoid this, it is
possible to force Software Motion Detection on Specific Stream.
To do so:
1. Open Camera Settings and go to Expert.
2. Check I have read the manual and understand the risks.
3. Choose Force motion detection for stream (Primary or Secondary).
4. Restart the camera.
IMPORTANT. Adjusting these settings may seriously affect the Server performance!
