i have done it as below. it wrong or right ?
string hostName = Dns.GetHostName();
           string myIP = Dns.GetHostByName(hostName).AddressList[0].ToString();

           myIP = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
           if (myIP == "" || myIP == null)
           {
               myIP = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
           }
           string fileName = myIP.Replace(".", ".") + "." + DateTime.Now.ToString("dd-MM-yy_hh-mm");
           //string fileName = DateTime.Now.ToString("dd-MM-yy_hh-mm");
           byte[] imageBytes = Convert.FromBase64String(data.Split(',')[1]);
           //Save the Byte Array as Image File.
           string filePath = HttpContext.Current.Server.MapPath(string.Format("~/CapturedImage/{0}.jpg", fileName));
           File.WriteAllBytes(filePath, imageBytes);
           return true;

Instead of creating longer filenames, try creating a tree like folder structure e.g
IP address (192.168.0.1)
|_ UserLoginName (if authentication based) or GUID based
|_ PC1
|_ Cam1
|_ DatetimeFormat.jpg

Computer follows instructions, if you able to identify the camera manualy then apply that in code

Hope you got the point

i have below code which is used to capture image by webcam in web app C#.
i want to implement this for multiple computer user. how to do i have no idea.
[WebMethod()]
      public static bool SaveCapturedImage(string data)
      {
          string ipaddress = Dns.GetHostName();
          ipaddress = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
          if (ipaddress == "" || ipaddress == null)
          {
              ipaddress = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
          }
          string fileName = ipaddress.Replace(":", "_") + "_" + DateTime.Now.ToString("dd-MM-yy_hh-mm");
          //string fileName = DateTime.Now.ToString("dd-MM-yy_hh-mm");
          byte[] imageBytes = Convert.FromBase64String(data.Split(',')[1]);
          //Save the Byte Array as Image File.
          string filePath = HttpContext.Current.Server.MapPath(string.Format("~/CapturedImage/{0}.jpg", fileName));
          File.WriteAllBytes(filePath, imageBytes);
          return true;
      }

You can use GUID ( a 16 digit characters), allot them an alias name like (near window, in front of table1, whatever best suits you to identify) then do your stuffs.

BTW, if you can share the project scenario we can have better solution as well but you can try above .
