Video Surveillance on unRaid

Inspired by everyones favourite unRaid you tuber SpaceInvaderOne's then partially completed series on setting up CCTV in unRaid, I figured it was time to get started on a little bit of home security.

I'd previously worked on building an interface to my legacy Comfort alarm / home control system, and that's fine for basic alarm, but video was always the next step.

SpeaceInvaderOne conducted a basic analysis of cameras and software available, before publishing a walkthrough of how to set up his chosen Shinobi docker. This, along with some other research, started me on my journey. I went ahead and purchased two of the SV3C 1080p PoE cameras he mentioned. These would connected to the spare PoE ports on my Unifi Switch 8 (see my Unify blog post for more details).

I tried installing Shinobi, (before the walkthrough dropped), and failed miserably. In any case, I'd previously researched the area and at the time decided that Blue Iris looked like the best option for scalability and integration.

The Grand Plan

Welcome to Mediaserver8, a place where I document my adventures in home automation and media serving - mostly for my own reference and future sanity!

I'm going to keep this post on top and maintain the overview schematic at Gliffy to offer an introduction to my HA system as it evolves. (Here's a direct link to a scalable version of this diagram).

Seeking Comfort

Embarking on the great home automation project of 2016, I wanted to get my openHAB installation talking to my legacy Comfort system.

I'd installed the comfort system 15 years ago, (it's a Comfort Pro), and it's been very reliable if somewhat basic since. At it's core, it's a home automation system that can function as a security system, telephone answering machine, lighting controller, infra-red blaster and a number of other tasks.

It's got a range of modular input and output systems and in my case, connects to the outside world via an RS232 serial interface. (USB and Ethernet options are also available but I don't have them). The system can be programmed and works on the basis of zones/inputs and responses so can be set up to, say, switch a light on if a particular sensor is tripped after dark.

I have window and door sensors connected up as well as a few PIRs as well as an X-10 interface for lighting control. There's a doorphone at the front door and the system is connected to the telephone line. This means that if we're not at home and the doorbell rings, we can set the system to call a mobile and we can speak to the person at the door. Neat.

Comfort has been updated over the years and version 2 has been out for a while with support for more modern protocols etc. but as an upgrade would require me to replace the entire system, I didn't bother.

Now with a renewed interest in home automation and a decision to pursue openHAB as the core, I needed to find a way to get Comfort and openHab linked up. I really don't want to throw out a perfectly good alarm system and have to rebuild it all again with new components just to get the same functionality. My ambition is to reuse and recycle what I have if it's fit for purpose.

A Winter Project

When we renovated our house over 15 years ago, we put in some automation systems. The brain was a Comfort system from Cytech. This is fundamentally an alarm system that does a few other things such as offering a voicemail system and has expansions for IR blasters and the like. It's accessible via a serial interface and programmable via 'comfigurtor' software. Connected to the comfort system are a set of window and door contacts, a doorphone, keypads and some PIRs.

Also installed were a number of hard wired X10 controllers (LD11 din-rail dimmers) which were set to control various lights via wireless switches and could be addressed via the comfort system (when coming home and entering the system disarm code, switch on the lights if it's after dark etc.)

In recent times, the X10 systems have been gradually degrading. Lights would switch on by themselves or fail to operate on command. It was time to start looking for options.

MQTT bi-directional communications in PERL

In attempting to interface openHab with my Comfort system, I needed to adapt an existing Perl linux driver for Comfort to work in Windows. The idea is that a small Perl program manages serial communications with the Comfort system and uses the IoT protocol MQTT to pass messages back and forth with openHab.

In doing so, I found that there was a very limited amount of information on integrating MQTT with Perl. There is a minimal MQTT interface for Perl that does the trick but the sample code was not obvious to me and there's very little else out there.

I've written a vey basic Perl <-> MQTT program to show how basic input and output is achieved.
