def __init__(self, hass, url, port, name, username, password):

        self._url = url
        self._port = port

        self._password = password

        # Establish camera
        self.camdata = HikCamera(self._url, self._port, self._username, self._password)

        if self._name is None:
            self._name = self.camdata.get_name
