Update configuration for Sercomm iCamera2
Can you please update the config at https://sunoo.github.io/homebridge-camera-ffmpeg/configs/Sercomm-iCamera2.html to the following? I am the author of the information on that page and originally submitted it under #1274 - "Sercomm iCam2 tested configuration". Thank you.

**Manufacturer/Model:**
Sercomm iCamera2

**Homebridge Config:**

      {
        "name": "[Camera_Location_Name]",
        "manufacturer": "Sercomm",
        "model": "iCamera2",
        "serialNumber": "[CAMERA_SERIAL_HERE]",
        "videoConfig": {
            "source": "-i rtsp://administrator@[CAMERA_IP]:554/img/media.sav",
            "stillImageSource": "[LEAVE THIS BLANK]",
            "audio": true
        }
      }

**Additional Information:**
I've created a full how-to on my GH page (https://github.com/Falc0n2k/Homebridge-Sercomm-iCamera2) that might help folks get set this up in a lot less time than it took me.
