How to detect if a camera is working using c#

C#

I am trying develop a camera solution that will take snap shots of events and send them to a remote server using c#. I want to send an alert if the camera is not capturing, or disabled or mal-functioning.

I used Aforge to take the snap shots like this

#region AFORGE ORIGINAL

/// <summary>
/// This section starts the camera software by way of initialization
/// </summary>
private void StartCameras()
{
InitializeCameras();

//create first video source
VideoCaptureDevice videoSource1 = new VideoCaptureDevice(videoDevices[int.Parse(System.Configuration.ConfigurationManager.AppSettings["VideoSourceIndex"].ToString())].MonikerString);
videoSource1.DesiredFrameRate = 10;
videoSourcePlayer1.VideoSource = videoSource1;

videoSourcePlayer1.Start();

}

/// <summary>
/// this method is used to stop the camera
/// </summary>
private void StopCameras()
{
videoSourcePlayer1.SignalToStop();
//videoSourcePlayer1.WaitForStop();
}

/// <summary>
/// Camera initialisations
/// </summary>
private void InitializeCameras()
{
cameraNames = new ArrayList();

try
{
videoDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice);
if (videoDevices.Count == 0)
{
throw new Exception();
}

for (int i = 1, n = videoDevices.Count; i <= n; i++)
{
string cameraName = i + " : " + videoDevices[i - 1].Name;

cameraNames.Add(cameraName);

System.IO.File.AppendAllText(Application.StartupPath + "\\Cams.txt", DateTime.Now.ToString() + " " + cameraName + "\r\n");
}

//check cameras count
if (videoDevices.Count == 1)
{
cameraNames.Add("Only one camera found");

}
else
{

}


}
catch
{
cameraNames.Add("No camers found");
}
}
