  Support for IP Cameras.
  
  This component provides basic support for IP cameras. For the basic support to
  work you camera must support accessing a JPEG snapshot via a URL and you will
  need to specify the "still_image_url" parameter which should be the location of
  the JPEG image.
  
  As part of the basic support the following features will be provided:
  -MJPEG video streaming
  -Saving a snapshot
  -Recording(JPEG frame capture)
  
  To use this component, add the following to your config/configuration.yaml:
  
  camera:
      platform: generic
      name: Door Camera
      username: YOUR_USERNAME
      password: YOUR_PASSWORD
      still_image_url: http://YOUR_CAMERA_IP_AND_PORT/image.jpg
  
  
  VARIABLES:
  
  These are the variables for the device_data array:
  
  still_image_url
  *Required
  The URL your camera serves the image on.
  Example: http://192.168.1.21:2112/
