DW Spectrum® IPVMS v4.2.0.32842 Release Notes

New Firmware Version:  v4.2.0.32842

Current Firmware Version:  v4.2.0.32660

Release Date:  May 3, 2021

New Features

OS Platform Support Changes

  • Windows 7 compatibility support ended.
  • Windows 2008 R2 compatibility support ended.
  • Added support for MacOS 11 in the desktop client.

New Features and Changes

  • Redesigned PTZ controls - PTZ controls have been redesigned for improved UX.
    • Advanced PTZ activates only when the Shift key is pressed.
  • 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.
  • Fisheye lens projection options - Improve fisheye dewarping precision by selecting the most suitable lens projection type:
    • Equisolid
    • Equidistant
    • Stereographic

New Device Support

  • Added advanced PTZ support for Hikvision IPC6412LR-X5P, IPC6854SR-X38UP-VC, IPC6222E-X33UP, IPC6222EI-X22UP-C.
