Best approaches for dynamic object tracking outside of camera FOV?

I'm building some prototypes in Hololens 2 with Unity 2020 + OpenXR + MRTK 2.7 exploring options for tracking moving objects. I have a lot of success with dynamic tracking options within the camera's FOV and computer vision, but I'm curious about what approaches would be suggested for dynamic tracking outside of the camera's FOV? I understand how I can use object anchors to mark a static object in space, but what about constantly tracking a moving object? I'm open to utilizing 3rd party components and libraries, or even specific hardware for this purpose like iBeacons/BLE beacons, but are there any Microsoft specific solutions that might be usable for this?

    Hello, Welcome to Microsoft Q&A,

    For clarification, the tracking services provided by Azure officially are based on the cameras and image recognition algorithms. For the object tracking inside the camera FOV, you can consider using QR codes detecting. But we don’t support tracking the trajectory of objects outside the camera FOV. As you said, you can consider using the third-party solutions, like the BLE location estimation, etc. We don’t have Microsoft ready-to-use solution from this perspective.
