DW Spectrum® IPVMS v4.1.0.31768 Patch Notes

New Software Version:  v4.1.0.31768

Current Software Version:  v4.1.0.31401

Release Date:  September 10, 2020

New Features

Redesigned PTZ Controls

PTZ control has been redesigned for improved UX.  To enable the new PTZ user interface, go to Local Settings in the Desktop Client and uncheck the “Show aim overlay for PTZ cameras” checkbox.

Intel® Quick Sync Video

Intel® Quick Sync Video uses the dedicated media processing capabilities of Intel® Graphics Technology to decode and encode fast, enabling the processor to complete other tasks and improving system responsiveness. Vastly improves the ability of low power hardware (e.g. Intel Atom, Celeron) and the ability of the Desktop Client to decode very high resolution (e.g. 16 MP, 32MP) cameras and streams.

  • Go to Local Settings in the Desktop Client and check the “Use Hardware Video Decoding” checkbox to enable Intel® Quick Sync Video
  • Use Hardware Video Decoding” is unchecked by default

SDK Fixes

Metadata SDK:

  • Added a method for plugins to get the Server’s built-in SDK version.
  • Performing a text search for object type in the Desktop Client led to analytics metadata not working properly during playback. Fixed.
  • Metadata was received from Stub Analytics Plugin only after Server restart. Fixed.
  • When a plugin is enabled on a camera, and its settings are saved by pressing the "OK" button, settings values were not updated in GUI when the plugin setting dialog is being opened again. Fixed.
  • Stub Analytics Plugin: “throwPluginDiagnosticEventsFromDeviceAgent” setting was renamed to “throwPluginDiagnosticEventsFromEngine”.
