Product Line

Pelco Video Management

Environment

  • Digital Sentry
  • DS ControlPoint
  • DSSRV
  • DS NVs
  • Audio

Cause

The Bandwidth Throttle option in the DS ControlPoint client is configured causing an interruption in the audio stream.

Resolution

There are 2 possible resolutions to correct the Bandwidth Throttle interruption.

  • 1. Bandwidth Throttle Override
  • 2. Disable the Bandwidth Throttle

     
  1. Use the Throttle Override option to temporarily override the bandwidth limitation.
    1. In DS ControlPoint, navigate to SETUP > Application Settings > Bandwidth tab > Throttle Override.  Place a check mark in the "Allow override...for" with All Systems or Individual (your choice, default is All Systems.)  How long the throttle override will last be default can be set in Dwell Information > Override Length.


       
    2. Click OK to save.
       
    3. Perform a video search in DS ControlPoint on the camera which is experiencing the problem, either before starting video playback or during playback press the keyboard key B to bring up the Throttle Override window - ThrottleAssistant.  The Override Length can be adjusted manually if need.  Press the Ok button to override the bandwidth throttle again if needed, the override time will count down and display how much time is left.

      Note: The ThrottleAssistant will only display if the bandwidth throttle is configured to limit the frame rate, if the slider is set to "No Bandwidth Limit" nothing will happen when B is pressed.


       
    4. Playback the video while the throttle is being overridden and the audio should now be as smooth as when viewing live.


       
  2.  Disable the bandwidth throttle configured in DS ControlPoint.
    1. In DS ControlPoint, navigate to SETUP > Application Settings > Bandwidth tab.
       
    2. Under Bandwidth Settings, drag the slider to the right until "No Bandwidth Limit" is displayed.
