PI Zero Bicycle Dashcam Python Service

	#!/bin/python3
	# Python script for using my Pi Zero as a Bicycle Dashcam which also live streams
	# to an rtsp-simple-server running at home
	# Recommended to start as a user systemd service

	# This script requires user access to /sys/devices/platform/leds/leds /sys/class/leds
	# Also recordings folder tends to corrupt very easily and should be its own filesystem
	# I use NTFS to allow police/other windows 10 users to access recordings
	# - DO NOT bother with vfat it is too unreliable
	# I use the following commands in /etc/rc.local to prepare for running this script

Zoneminder Record High-res H264 streams 24/7 with low CPU Load

	>>>>>>>>>>>>>>>>>>>>> BIG UPDATE <<<<<<<<<<<<<<<<<<<<<<<<<<<<
	On zoneminder version 1.35.16 and later there is a DecodingEnabled setting for each monitor - this script is therefore of little use anymore
