Hi,
I looked at the doc Synchronize multiple Azure Kinect DK devices and it's mentioned there that typically each Azure Kinect DK uses its own host computer:
Typically, each Azure Kinect DK uses its own host computer. You can use a dedicated host controller, depending on how you use the device and how much data is transferred over the USB connection.
Make sure that the Azure Kinect Sensor SDK is installed on each host computer. For more information about how to install the Sensor SDK, go to Quickstart: Set up your Azure Kinect DK.
Therefore it is my understanding that if you Calibrate the devices as a synchronized set you should be good to go.
Let me know if I could answer your question?
Thanks!
