Device Data Hub

info

The Device Data Hub is availbe from Axis OS 12.11

The Device Data Hub is an internal component (via the ACAP Native SDK) that enables efficient communication between applications on the same device. It uses a publish/subscribe pattern to eliminate direct coupling between different processes, making it easier to exchange data without introducing build-time dependencies.

Applications communicate with the Device Data Hub through a C API. For more information, see Device Data Hub documentation. For an example of how to consume Axis Scene Metadata via an acap see acap native sdk examples.
