Tomorrow is move-in day, and what better time to talk about security systems, since there will actually be possessions in the house for the first time.
Security is kind of a tough thing to blog about since the more I publish about my setup, the easier it would be for miscreants to subvert it. I’m sure everyone reading this blog on a regular basis is an honest member of society, but you never know who might come in through Google one day. So… for that reason, I must say very little. What I will say is this though: I’m going to lay out a few details in this post about how we secure the house and then I’ll do a separate, more comprehensive post on all the great home automation we’ve built in.
To start off with, we have contact sensors on every single opening in the house. Doors, windows, sliders, Nanas, garage door… you name it. When any perimeter orifice is opened, the central alarm/automation system knows about it. This is not only useful for security but also for doing cool things like turning on lights when doors are opened.
The second layer of protection is glass breakage sensors. We have these all over the house. They work by detecting the audio frequency emitted when glass is broken. If any window in the house breaks, the alarm/automation system knows about it.
The third layer of protection is motion sensors. As the name suggests, these trigger when they detect movement in the house. Some people choose to keep these on only when the house is empty and some people have certain zones on all the time. These are also useful for doing things like automatically turning on the stair lights when you’re about to walk up or down stairs.
We also have a siren on each floor and one on the roof for maximum ear piercing delight. When the alarm triggers, a monitoring service is alerted as well as a few cell phones including mine.
There’s a bit more to it than this even, but we’ll just leave it at that for now. I will say this: if you’re building a house, do not skimp on wiring, whether it’s alarm wiring or data. It’s very tempting to ask yourself “do I really need a sensor here?”, but spend the extra few bucks and run every single wire you could possibly need. You won’t regret it. Most of these sensors are less than $20 apiece (for top of the line, great ones even!) so all you’re really paying for is your wiring guy’s labor. Well worth it.
Do not worry about overwiring. Do worry about underwiring.
I’m really looking forward to move-in day tomorrow. There are several more big posts coming including the hardwoods, the landscaping, the kitchen, and the bathrooms.
UPDATE: Nina in the comments reminded me about cameras. I totally forgot to mention those. We have several infrared, high resolution, night-vision cameras which monitor almost every angle of the house 24 hours a day. The footage is available live via a streaming server as well as recorded via a dedicated DVR. Everything is also on battery backup in case of a power failure.
