MQTT
Axis devices can distribute data sources using MQTT, providing an efficient method for data generated by both the Fusion Tracker and Track Consolidation modules to anyone from cloud services, IoT platforms, and edge applications.
The api for configuring MQTT for scene metadata can be found here Analytics MQTT API. The Analytics MQTT API data sources match the released data sources with an additional "#channelID" suffix to allow subscribers to select the channel on multi channel devices.
There is also a MQTT How-to guide for guidance on how to set up scene metadata streaming over MQTT.
For configuring other types of data via MQTT, please have a look at the event system MQTT integration.
Be aware that scene metadata topics may generate large amounts of data, especially when enabling object snapshots. Please make sure the MQTT broker can manage the load to avoid dropping data.
