# ObjectTrackerConfig

`ObjectTrackerConfig` stores the parameters that drive the
[`ObjectTracker`](https://docs.luxonis.com/software-v3/depthai/depthai-components/nodes/object_tracker.md) node. It lets you
configure tracker types (zero-term / short-term), association thresholds, maximum number of simultaneously tracked objects, and
ROI re-acquisition behavior when detections are temporarily lost.

Set `ObjectTracker.initialConfig` to establish defaults and send live updates through `inputTrackerConfig` when you need to adapt
the pipeline—for example, to increase the IOU threshold in crowded scenes or to switch from median-flow to kernelized correlation
tracking. The node will apply the new configuration without requiring a pipeline rebuild.
