Device Data Hub

info

The Device Data Hub is available starting with AXIS OS 12.11.

The Device Data Hub is an internal component available through the ACAP Native SDK. It enables applications on the same device to communicate efficiently through a publish/subscribe pattern. This lets processes exchange data without direct coupling or build-time dependencies.

Applications communicate with the Device Data Hub through a C API. For more information, see the Device Data Hub documentation. For an example of how to consume AXIS Scene Metadata from an ACAP application, see the ACAP Native SDK examples.
