# ==========================================================================
#
# This module contains the implementation of the Vivotek PT7135 protocol
# It is easy to adapt to other Vivotek cameras. I have found a lot of commands with Wireshark
# This protocol get some info from the camera through receiveCmd function.
# Implement a pseudo diagonal movement
# Where go "presetClear" function from php code?
# Any improve is welcome, and please share it
