+### Multi-Camera
+
+Run one instance per camera, each with its own camera index and socket path:
+
+```bash
+./build/vizionStreamer --camera 0 --socket /tmp/vizion_cam0.sock &
+./build/vizionStreamer --camera 1 --socket /tmp/vizion_cam1.sock &
+```
+
+Point the control scripts at a specific instance with `VIZION_SOCKET`:
+
+```bash
+VIZION_SOCKET=/tmp/vizion_cam0.sock ./scripts/start_stream.sh
+VIZION_SOCKET=/tmp/vizion_cam1.sock ./scripts/set_pipeline_udp.sh 192.168.1.100 5001
+```
+
+Without the env var, scripts default to `/tmp/vizion_control.sock` (single-camera usage).
+
+CLI options:
+
+```
+-c, --camera <idx>   Camera index to open (default: auto-detect VCI-AR0234, else 0)
+-s, --socket <path>  Control socket path (default: /tmp/vizion_control.sock)
+-h, --help           Show help
+```
