#!/bin/bash  
#
# ARGUMENTS:
#
# $1 -> start, update, stop
# $2 -> IP address of the domotikad daemon
# $3 -> type of event (motion only for the moment)
# $4 -> camera name
# $5 -> a string with camera name followed by a list of zones involved in the event, like
#       "CAM1: zone1, zone2", it take only the part after : and expect to find a list of
#       zone names separed by ", " (a comma and a space)
# $6 -> cam path (contain camera stream uri and other info like: rtsp://192.168.1.101/h264 -
# $7 -> monitor id
# $8 -> event id
#
# MYSQL CONFIGURATION:
#
# after using sudo to  permit root execution from the mysql user and add a regular shell
# to mysql user,
# 
# Add UDF sys_eval function to mysql and then:
#
# Add event to mysql zoneminder db with:
#
# delimiter EOF;;
# create trigger zmalarm_start after insert on Events
#    for each row
