Intel Quick Sync Video (QSV) is a technology available on some Intel processors, that provides hardware acceleration for video encoding/decoding. QSV offloads video encoding/decoding to a dedicated hardware CPU core, providing faster results and reducing the video footprint on server CPU performance.

Axxon One applies Intel QSV for decoding:

  1. Video formats: H.264, H.265 and H.265+.

  2. Live, Archive modes (forward playback only) and TimeCompressor.


If the Client shares the same PC with a Server which applies a detection tool to а video stream, Intel Quick Sync Video will not be used for displaying this stream.


Maximum pixel resolution depends on your particular version of the Intel Quick Sync core; refer to https://www.intel.com/content/www/us/en/homepage.html for details.

To use Intel Quick Sync Video, make sure your system meets the following requirements:

  1. Since QSV is incorporated into the graphics processor, your CPU must have one (iGPU). 

    You  can check if the CPU supports QSV here. 


    For H.265 and H.265+ video, Intel Quick Sync Video technology is supported only on Intel processors with microarchitecture: Braswell (only decoding), Cherry Trail (only decoding), Skylake, Apollo Lake, Kaby, Gemini, Coffee Lake.


  2. The mainboard supports iGPU (includes Flexible Display Interface). 

  3. The Graphics driver supports QSV. We recommend using the latest version of the Intel HD Graphics Driver.

    You can also update the driver automatically using the Intel Driver Update Utility.


To activate the Intel QSV in Axxon One you need to:

  1. Enable using the integrated graphics option in the BIOS settings. 

    Depending on the BIOS version, it may be named differently (iGPU, Internal Graphics, Integrated Graphics Adapter − PEG).


  2. In general, the simultaneous use of the integrated graphics unit (iGPU) and external GPU has to be avoided. In this case, to use Intel QSV, do as follows:
    1. enable Multi-Monitor in the BIOS settings;

    2. connect a “Fake/Virtual” Monitor/Display on Windows and then connect it to your iGPU and select Extend desktop to this display in the Multiple displays list.

  3. Go to Settings → Options → User Interface (1-2). 
  4. Select the Enable hardware decoding checkbox (3).
  5. Click Apply to save the changes
