Hi, @weibinliu. This delay is usually caused by one of two things:
Once you start streaming the sensors in the Multicam context, check the ‘Sync Mode’ field in the ‘Sensor Configuration’ panel to ensure that it reads ‘Multicam Master’ or ‘Multicam Subordinate’ - (This will be grayed out, and automatically set based on how the sync cables are arranged). If it says ‘Standalone’ for any of the sensors, check the connections of each sync cable to ensure they are plugged into the proper port and well-seated, or try swapping out different cables.
Check that the firmware matches on each Azure Kinect. If it doesn’t, you can update the firmware using the resources found here.
