    private void ButStartClick(object sender, EventArgs e)
        {
            GetFrame();
        }

        private void GetFrame()
        {
            //string sourceURL = "http://192.168.0.102";
            string sourceURL = "http://192.168.0.102/jpg/image.jpg";
            //"http://192.168.0.102:4747";

            byte[] buffer = new byte[1280 * 800];
            int read, total = 0;
            HttpWebRequest req = (HttpWebRequest)WebRequest.Create(sourceURL);
            WebResponse resp = req.GetResponse();
            Stream stream = resp.GetResponseStream();
            while ((read = stream.Read(buffer, total, 1000)) != 0)
            { total += read; }
            Bitmap bmp = (Bitmap)Bitmap.FromStream(new MemoryStream(buffer, 0, total));
            pictureBox1.Image = bmp;
        }
