    xOut.setStreamName("camOut")

    # Here we will send camera preview (ImgFrame) to the host via XLink.
    # Host can then display the frame to the user
    cam.preview.link(xOut.input)

  .. code-tab:: c++

    dai::Pipeline pipeline;
    auto xOut = pipeline.create<dai::node::XLinkOut>();
    xOut->setStreamName("camOut");

    // Here we will send camera preview (ImgFrame) to the host via XLink.
    // Host can then display the frame to the user
    cam->preview.link(xOut->input);
