Ability to control the Spectra Pro PTZ degrades with motion and audio turned on, the bit rates will need to be lowered

Issue

When using audio and/or motion detection the drivability control of the Spectra Pro PTZ degrades and the bit rates need to be lowered to help regain control

Product Line

Pelco Cameras, Pelco Video Management

Environment

Spectra Pro PTZ when using audio, window blanking and motion detection

Cause

The use of Motion detection, Audio, or Window Blanking requires more CPU processing power and communication processing.

Resolution

Please see the following chart for best settings;

  1. If using Motion and Window Blanking the CVBR maximum should be 4200 kbps
  2. When using Audio and Window Blanking the CVBR should be maximum of 4200 kbps
  3. Window Blanking only the maximum CVBR is 4200 bps
  4. If using Motion, Window Blanking and Audio the maximum CVBR should be 3600 kbps

Basically, if one item is used the CVBR should be maximum of 4200 kbps, if two items are used the CBVR should be maximum of 4200 kbps, and if three items are used the CVBR should be a maximum of 3600 kbps.

If using CBR the maximum should be 4000 kbps.
