Camera ID - ID string of the tracker to be used for the camera tracking. The tracking systems can send data for multiple physical trackers at the same time and this ID can filter them. For stYpe, this should always be "0".

Protocol – The tracking system (protocol) to use.

Port – The UDP port on which to listen for tracking data. Required for stYpe, FreeD, EZtrack, LONET 2, not used for OptiTrack and Vicon.

FOV – Horizontal field of view override in degrees. This option is used to override the FOV value from the tracking system or the scene. By default, it's 0.0, which means that the override is disabled and the value from the tracking system or the scene is used. When disabled, the FOV is taken from the tracking system if it supports FOV tracking and currently provides a valid positive value or from the main camera exported in the scene.

Recording Directory – A directory for the recorded camera tracking Alembic files. By default, it's the Windows %TEMP% directory.

Sync Recording to Animation – When enabled, tracking samples are recorded only during the first animation playback with the exact animation times as rendered. This ensures that the exported Alembic file matches the scene animation when imported to the same scene. When disabled, all received samples are recorded with uniform time sampling based on the average FPS of the received data.

Unit Scale – Scaling factor for the position data received from the tracking system. Can be used for the correction of incorrectly calibrated tracking systems or scenes with a wrong scale. Normally it should not be needed.

1 button – Reset the scaling factor to 1.0.

Uniform Scaling – If enabled, the scaling is uniform on all dimensions; otherwise, it can be specified for each dimension separately.

Horizon Shift – Horizon shift effect for the camera inner frustum. Similar to a vertical lens shift effect.
