=head1 DESCRIPTION

This module contains the implementation of the Foscam FI8908W / FI8918W IP camera control
protocol.

The module uses "Control Device" value to retrieve user and password. User and password should
be separated by colon, e.g. user:password. If colon is not provided, then "admin" is used
as a fallback value for the user.
