+ **Object Recognizer**:
+   - No environment variables specified.
+
+ **Motion Detector**:
+   - `INDEX`: A unique identifier for each motion detector instance (e.g., `1`, `2`, `3`).
+   - `OR_HOST`: The hostname of the **object recognizer** service (set to `object_recognizer`).
+   - `OR_PORT`: The port on which the **object recognizer** service is listening (set to `9999`).
