 ## Detection
 
-Object detection uses the [apple-silicon-detector](https://github.com/frigate-nvr/apple-silicon-detector) with a YOLOv9-t model (`yolo-generic`, 320x320), running natively on [[indri]] as a LaunchAgent (`mcquack.eblume.frigate-detector`). It communicates with Frigate via ZMQ over TCP (`tcp://host.minikube.internal:5555`), using CoreML with partial Neural Engine acceleration (~50-80ms inference, down from ~117ms with in-pod ONNX CPU).

Model ONNX files are stored on the NFS volume at `/media/frigate/models/`.
 
-A `driveway_entrance` zone is configured for alert filtering — only detections in this zone trigger review alerts.
+Two zones are configured: `driveway_entrance` (triggers review alerts for person/car) and `driveway` (triggers review detections).
