How to show video of an IP camera

Hello there! I've spent last week tryin to show my ip camera's video in my unity 3d application , and i did , but the video displayed is TOOO slow ( around 2-3 fps ).

This is my actual code :

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine.UI;
 
 public class CameraManager : MonoBehaviour {
 
 
     public string url;
     public string username;
     public string password;
     public RawImage img1;
     public RawImage img2;
     public Text consolle;
     public InputField ip;
     public Texture2D cam;
 
 
     public void Start() {
         UnityEngine.Time.timeScale = 1;
         cam=new Texture2D(1, 1, TextureFormat.RGB24, true);
     }
 
     public void StartFetching(){
         if (ip.text != "") {
             url = "http://" + ip.text + "/snapshot.cgi";
             StartCoroutine (Fetch ());
         } else {
             consolle.text += "\r\n 'Ip' field cannot be empty";
         }
     }
 
     public void StopFetching(){
         StopAllCoroutines ();
     }
 
 
     public IEnumerator Fetch() {
         while(true) {
             
                 WWW www = new WWW(url, null, new System.Collections.Generic.Dictionary<string,string>() {
                 {"Authorization", "Basic " + System.Convert.ToBase64String(System.Text.Encoding.ASCII.GetBytes(username+":"+password))}
                 });
 
                 yield return www;
                 Debug.Log ("doing");
                 if(!string.IsNullOrEmpty(www.error))
                     consolle.text += "\r\nConnection with ip cam failed! : "+www.error;
                 try{
                 www.LoadImageIntoTexture(cam);
                 }catch(UnityException e){
                     consolle.text += e;
                 }
                 img1.texture = cam;
                 img2.texture = cam;
 
         }
     }
         
 
 }

Now i want to know if exists some other method to make the video more faster and less choppy, the problem it's not the connection as i know that the video in my android application ( "FRCAM" , my ip-cam is an FREDI HD L17 ) is displayed at 20 fps ( which is good for what i'm using ) , the URL i could use for get the video is :

Any ideas ? I'm really frustrated.
