# DESCRIPTION:
#   Handling Hikvision PTZ-cameras sequences.
#   Additionally:
#   - get ds18b20 sensor value over SSH,
#   - saving pictures to FTP.
#   This is only a local "proof of conept" for testing and debugging.
#
# DEPENDENCIES:
#   - curl
#   - sshpass
#
# PARAMETERS:
#   1: "qn" - execution without pauses
#   2: custom configuration file path
#
# FUNCTIONS:
