Some of you know that I installed a security system at our house instead of contracting it out to ADT or one of the other popular companies. I never blogged about the project, but it was a major project for me. The physical installation wasn’t very hard, but it took a ton of time to research what I needed to buy. I’m not going to go into specifics on this public site, but here is some of the basic info in case you’re interested in this for your own home.
The main reason you would probably want to consider this is that you can save a lot of money on your monthly bill. I think ADT is currently charging $37/month for their basic package. By doing it yourself, you can get the same monitoring coverage for $10/month. You don’t have to be a math whiz to know that saving $27/month adds up quickly.
Our house was previously serviced by ADT but there was no active service when we moved in. The panels that ADT uses are locked down. While they are standard models, they are tweaked so that you can only use them with ADT. The sensors that are already on your doors and windows are probably reusable. In our case, all of the sensors were hardwired and those are extremely simple to reuse. The “only” thing I had to do was replace the main control panel and the keypad.
In retrospect, I could have saved myself some time if I had just bought the exact same panel that was there before. It would have been obvious how to wire it up! But I went with a new panel mostly because I didn’t think of that option, and also because I wanted to be able to support wireless sensors. I’m glad the wired sensors were there, but I wanted to quickly and easily expand the coverage of the system.
Once I had the panel in hand, I carefully labelled all the wires on the old panel, disconnected the wires, and then reconnected everything. Programming is all done via the keypad and you’re interacting with 90s technology. Everything is done via long strings of numbers and you better have a firm grasp on the manual so you don’t get loss. It’s ridiculous, but it works.
I was able to confirm that the alarm worked locally so then it was just a matter of hooking it up to the phone line. You cannot use a VOIP telephone line (like the one you get from Comcast.) It must be an actual old-fashioned telephone line (POTS) or you can use a cellular monitoring system for a little extra money per month.
So is this a good DIY project? Ehhh… if you’re a geek and you’re willing to spend a lot of time reading manuals, you can figure it out. You’d also have the advantage of being able to call me up and learn from my mistakes. I’m thankful we have it but I spent a TON of time getting it going. I think a lot of that delay was because I was so nervous about dropping a few hundred bucks and then screwing it all up.
Our system has been rock solid and we use it regularly. We’ve only had one false alarm and that was attributed to a helium balloon slowly floating in front of a sensor. I love our custom solution because when I decide to add some more sensors, I can do it for $20-40/sensor. There’s no service call from a tech, crazy prices for installation, or additional monthly fees. And if I want to control it from my phone or hook it into a home automation system, it’s just some more research and purchases on my end. We’ve already added fire and carbon monoxide monitoring for a grand total of $0/month.
Is the system safe? Sure. I’m already using the layout that the “professionals” recommended for the house and then I’ve added more sensors on top of that. I can tell you that the fire sensors we got are exactly the same as the system that we put in at church for tens of thousands of dollars. A smart burgler could get through our system, but they could get through your ADT system at least as easily. I could spend more money to tighten up some of those holes, but at some point you just have to let it go. Having the sign out front is probably more important than the layout of our system.
I enjoy this kind of thing so it’s worth my time to save the money. Obviously the math is different for most people because companies like ADT are very successful!
Broken Window Theory
I hate cleaning, but even more than that, I hate looking at a mess and knowing that I have to “waste” my time and clean it. So my basic approach is to ABC: Always Be Cleaning. (Every self-help article like this needs a cheesy acronym, right?) For example, when I finish making dinner, I don’t leave the dishes in the sink to greet me the following morning, I take 5 minutes and clean them up. Doing little bits of cleaning here and there feels a lot less painful than ruining two hours of my Saturday because the kitchen turned into a nightmare.
Coupled with that, I also force myself to clean up the area before starting any project. Even if I clean up at the end of a task, the area slowly gets messy again. This is especially true out in the garage. So before I start that next big project, I pick up all my tools, clean off my bench, and organize the piles of wood. Then I’m excited to work in that nice clean area instead of tripping over stuff on the floor and never having room on the bench.
My approach can be neatly summed up by the Broken Window Theory. If you read that linked Wikipedia article, you’ll see the theory summed up like this:
It’s pretty easy to tell when an area is clean. I feel an emotional response to setting that first piece of junk in the nice clean area. But then I get used to seeing it there and it doesn’t bother me so much. In fact, it gets easier and easier to just throw more junk in that area because hey, I have to clean it out anyway, right? Pretty soon it’s a huge mess and now I have to do one of those big huge cleanouts and my quality of life is negatively impacted because I’m annoyed by the thought of that big cleaning event coming up.
It’s surprising how often this theory applies. For example, we talk about it regularly at work when someone proposes a less than beautiful piece of code. Just take the time to fix it now because your hack will open the floodgates for more hacks until we’re left with a nightmare that we don’t have time to re-architect. If you want to get a little geekier about it, you might propose that messes grow exponentially.
If you’ve already got a system that works for you, then stick with it! But if you need a little more encouragement, remember the broken window theory.
