# Perception

The Perception microservice detects and tracks objects in the warehouse from camera streams and publishes the results as metadata for downstream analytics. Choose the configuration page that matches your deployment profile.

* [2D Single Camera Detection and Tracking (RT-DETR)](/vision-agent/agent-workflows/industry-specific-examples/warehouse-operations-blueprint/microservice-configuration/perception/2d-single-camera-detection-and-tracking-rt-detr) - Per-camera 2D detection and tracking, used by the 2D profiles.
* [3D Multi Camera Detection and Tracking (Sparse4D)](/vision-agent/agent-workflows/industry-specific-examples/warehouse-operations-blueprint/microservice-configuration/perception/3d-multi-camera-detection-and-tracking-sparse4d) - 3D detection and tracking across multiple calibrated cameras, used by the 3D profile.
* [3D Multi Camera Detection and Tracking (MV3DT)](/vision-agent/agent-workflows/industry-specific-examples/warehouse-operations-blueprint/microservice-configuration/perception/3d-multi-camera-detection-and-tracking-mv3dt) - Multi-view 3D tracking where cameras share tracklets, used by the MV3DT profile.
