There are changes introduced to the metadata analytics stream in AXIS OS 10.10, scheduled for release in March 2022. See AXIS OS portal for more information about upcoming features in OS releases.

What will change in OS 10.10

In AXIS OS 10.10 we have restructured the AXIS Object Analytics (AOA) and Motion Object Tracking Engine (MOTE) metadata producers. AOA is not the producer for object classification metadata anymore. AOA will continue to work as an ACAP that provides its own events and detections. A new firmware component replaces the AOA ACAP as metadata producer. This new producer will continue to use in the metadata frames and it will use the metadata producer name “Axis object analytics” in the 10.10 release. 

Note: The names “objectanalytics” and “Axis object analytics” will likely be deprecated and replaced by other names in a later release to distinguish the metadata producer from the Axis Object Analytics ACAP. The Axis Object Analytics ACAP will remain unchanged.

The configuration of the metadata producers changes. It is now possible to configure the metadata producers via VAPIX, using the Analytics Metadata Producer Configuration API, or the ONVIF Analytics API. And, there is a new section in the WebGUI.

Note: Metadata configuration page is only available in the new GUI (ADA). See WebGUI under System -> Metadata to configure the metadata producers.

The metadata analytics stream now supports enabling several metadata producers at the same time.

Frames from all enabled producers are interleaved in the stream. The timestamps of frames from different producers are not guaranteed to increase between each frame, only between each frame from the same producer.

Axis video motion tracker metadata producer will be enabled as the factory default. Axis video motion tracker is may also be referred to as MOTE. It provides just bounding boxes and polygons.

Note: From 10.9, Axis video motion tracker frame elements includes . Before 10.9 no source was included in the frame elements.

When upgrading from 10.6 – 10.8 the enabled metadata producer will be configured according to the run status of the AXIS Object Analytics ACAP.

  • AXIS Object Analytics ACAP = On, results in the Axis object analytics metadata producer being enabled after the upgrade.
  • AXIS Object Analytics ACAP = Off, results in the Axis video motion tracker metadata producer being enabled after the upgrade.

New object classes

In Axis OS 10.10 release, the metadata from the Axis object analytics provider will add two new classifications and associated bounding boxes for: 

  • HumanFace
  • LicensePlate (location of the license plate on the image)
     

Note: The additional classifications will only be available on DL cameras.

Why these changes? What are the benefits?

We are introducing these changes to improve the structure around metadata producers. Now the metadata producers are configurable via WebGUI. AOA becomes more independent and can focus on more dedicated use cases.

Axis Object Analytics ACAP was never designed to be used as a metadata producer, but in order to meet the market demand, it was a temporary solution. Now we have a proper metadata producer in Axis OS. And, now the metadata producers are configurable. On top of that, AOA can focus what is designed for, to keep the data internally without exposing it to analytics stream, and provide better detections.

What should developers take into consideration?

A new firmware component replaces the AOA ACAP as metadata producer. This new producer will continue to use  in the metadata frames and it will use the metadata producer name “Axis object analytics” in the 10.10 release.

The names “objectanalytics” and “Axis object analytics” will likely be deprecated and replaced by other names in a later release to distinguish the metadata producer from the Axis Object Analytics ACAP. The Axis Object Analytics ACAP will be unchanged.

The configuration method changes, also note the factory default and upgrade behaviors. If you have guides on how to configure object classification in Axis products based on AOA, that is also needed to be updated.

For coming releases, it is good to be aware that:

  • There might be new metadata producers added
  • The factory default metadata producer might change
  • The contents of the metadata from the producers that already exist may evolve with new classifications and other additional data
