Code: Select all

# ==========================================================================
#
# This module contains the implementation of the Mobotix protocol
# It is easy to adapt to all Mobotix cameras. We have found a lot of commands 
# using: http://<IP-Camera>/control/click.cgi?help or http://<IP-Camera>/control/click.cgi?list
# Any improve is welcome, and please share it
