Small script for handling ZoneMinder offsite uploads

I created this to handle my ZoneMinder offsite uploads. My ZoneMinder setup at home will automatically upload images when motion is detected via SFTP to a server in the "cloud". This little script unarchives the uploaded images, and lets me browse them via HTTP. It adds the same html-file with a simple JavaScript based viewer as ZoneMinder itself uses when you export events.

• Set up your ZoneMinder instance to upload (see options) events (using filters) as TAR-files
• The default location I've configured in the script is /home/zm
• Create a directory where the unarchived files will end up, like /home/zm/untar
• Put this repository's two files in the same directory, make sure zmoffsite-process.sh has chmod +x permissions.
• Add a cronjob to run it automatically (example for every minute: */1 * * * * /home/zm/zmoffsite-process.sh)
• Install a webserver if you like, like nginx, and let this directory be served

In this last screenshot you can see the settings I'm using for the upload tab in ZoneMinder.
