private CameraURLBuilderWPF _myCameraURLBuilder;

private OzekiCamera _camera;

public MainWindow()
{
InitializeComponent();

_connector = new MediaConnector();

_provider = new DrawingImageProvider();

_detector = new MotionDetector();

videoViewer.SetImageProvider(_provider);

video MyWin = new video();
MyWin.Show();


}

void GuiThread(Action action)
{
Dispatcher.BeginInvoke(action);
}

private void StartMotionDetection()
{
_detector.HighlightMotion = HighlightMotion.Highlight;
_detector.MotionColor = MotionColor.Red;
_detector.MotionDetection += detector_MotionDetection;
_detector.Start();
}

void detector_MotionDetection(object sender, MotionDetectionEvent e)
{


GuiThread(() =>
{
if (e.Detection)
{
MotionEventLabel.Content = "Motion Detected";

}

else
MotionEventLabel.Content = "Motion Stopped";


video MyWin = new video(MotionEventLabel.Content.ToString());

});
}

private void StopMotionDetection()
{
_detector.Stop();
_detector.MotionDetection -= detector_MotionDetection;
_detector.Dispose();
}

private void MotionChecked(object sender, RoutedEventArgs e)
{
MotionEventLabel.Content = String.Empty;
var check = sender as CheckBox;
if (check != null)
{

else
StopMotionDetection();
}
}

private void Compose_Click(object sender, RoutedEventArgs e)
{
_myCameraURLBuilder = new CameraURLBuilderWPF();
var result = _myCameraURLBuilder.ShowDialog();

if (result == true)
{
if (_camera != null)
{
_camera.Disconnect();
videoViewer.Stop();
}

_camera = new OzekiCamera(_myCameraURLBuilder.CameraURL);
_camera.CameraStateChanged += _camera_CameraStateChanged;

});

Disconnect();
}
}

{

{

}
if (e.State == CameraState.Disconnected)
{
Disconnect();
}

});
