There are plenty of security systems out on the market that come with professional installation and support, but what about DIY setups that offer many of the same features and are often much cheaper? Here are the pros and cons of doing it yourself.
Many companies are getting in on the home security system market, especially smarthome brands like Nest, SmartThings, and Wink. For example, Nest has a DIY security system bundle that lets you install everything yourself and do your own self-monitoring from the Nest app, but you can also hook up professional monitoring if you want for a monthly fee.
许多公司正在进入家庭安全系统市场，尤其是Nest，SmartThings和Wink等智能家居品牌。 例如， Nest拥有一个DIY安全系统捆绑包 ，可让您自己安装所有内容并通过Nest应用执行自己的自我监控，但是如果您要按月付费，也可以连接专业监控。
The big question, however, is what the pros and cons are when deciding to go the DIY route, and how it compares to professional systems from the likes of ADT. Here are some things you should know about that.
您会为DIY支付更多的费用，但从长远来看它会更便宜 (You’ll Pay More Up Front for DIY, but It’s Cheaper In the Long Run)
It may be tempting to go with ADT, since you only have to pay a $99 installation fee to have everything installed in your house—sensors, alarms, and keypads. With a DIY setup, though, you have to pay for all the equipment yourself, and that can cost hundreds of dollars.
使用ADT可能很诱人，因为您只需支付$ 99的安装费，即可在您的房屋中安装所有东西-传感器，警报器和小键盘。 但是，使用DIY设置，您必须自己购买所有设备，这可能会花费数百美元。
However, when you get someone like ADT to hook everything up, you’re still paying for the equipment. You’re just doing it over time while they’ve got you locked into a three-year contract paying for the monitoring service, as well.
Let’s gather up some examples that we can compare. For this we’ll compare SimpliSafe, Abode, and ADT, the first two of which are security systems that you purchase up front and install yourself. Let’s start with ADT
让我们收集一些可以比较的示例。 为此，我们将比较SimpliSafe ， Abode和ADT，其中前两个是您预先购买并自行安装的安全系统。 让我们从ADT开始
ADT’s base package comes with a keypad, the siren, three door/window sensors, a motion detector, and a keychain remote. All you have to pay is the $99 installation fee up front, and then you’ll pay $36.99 per month for the 24/7 professional monitoring.
ADT的基本套件带有一个键盘，警报器，三个门/窗传感器，一个运动检测器和一个钥匙串遥控器。 您只需要支付$ 99的安装费，然后就可以每月支付$ 36.99的24/7专业监控功能。
There’s a big caveat, though. This plan requires that you connect the system to a landline as its only means of communication, which you may not even have. If you want or need a cellular connection, you’ll have to get CellGuard ($48.99/month) or ADT Pulse ($52.99/month). The latter option allows you to arm/disarm your system remotely and receive alerts on your phone.
不过，有一个很大的警告。 此计划要求您将系统连接至座机，这是其唯一的通讯方式，而您甚至可能没有。 如果需要或需要蜂窝连接，则必须获得CellGuard (每月48.99美元)或ADT Pulse (每月52.99美元)。 使用后一个选项，您可以远程布防/撤防系统并在手机上接收警报。
Keep in mind that ADT often runs specials where they’ll waive the $99 installation fee or give you a $100 gift card as a sign-up bonus of sorts (essentially waiving the installation fee), but for comparison’s sake, we’ll leave the installation fee in there.
请记住，ADT经常会打折促销，他们会免除$ 99的安装费或给您$ 100的礼品卡作为某种形式的开卡奖励(实际上免除了安装费)，但出于比较的考虑，我们将保留那里的安装费。
When all is said and done, the total cost over three years for ADT (with Pulse) would be $2,006.64.
综上所述 ，ADT(使用Pulse)三年来的总成本为$ 2,006.64 。
The SimpliSafe package that most closely matches ADT’s base package costs $259. The only difference is that it doesn’t come with a keychain remote, but we can add that in separately for $25, making the total cost you’ll need to pay up front $284.
与ADT基本封装最接近的SimpliSafe封装的价格为259美元 。 唯一的区别是它没有钥匙扣遥控器，但我们可以单独添加它，价格为25美元，这样一来，您需要支付的总费用为284美元。
For professional monitoring, SimpliSafe offers two tiers. The cheapest plan is $14.99 per month, but doesn’t offer the ability for you to receive alerts and self-monitor your system while you’re away from home. You’ll need to pony up for the $24.99/month plan in order to get that feature.
对于专业监控，SimpliSafe 提供两层 。 最便宜的计划是每月14.99美元，但不提供在您外出时接收警报和自我监控系统的功能。 您需要为$ 24.99 /月的计划付诸东流，以获取该功能。
So, with the $284 up front cost and the $24.99 monthly fee, the total cost over three years for SimpliSafe would be $1,183.64, which is $823 cheaper than ADT. Even if we waive ADT’s installation fee and go with the cheapest plan (rather than get Pulse), you’d still come out on top by going with a DIY setup. Plus, SimpliSafe doesn’t require a contract at all, so you can cancel your service anytime.
因此，使用$ 284的前期成本和$ 24.99的月费，SimpliSafe三年的总成本为$ 1,183.64 ，比ADT便宜$ 823。 即使我们免除ADT的安装费用并采用最便宜的计划(而不是获得Pulse)，您仍然可以通过DIY设置获得最高的收益。 另外，SimpliSafe完全不需要合同，因此您可以随时取消服务。
We’ve tried out Abode before and it’s also a great DIY security system. It’s also cheaper than ADT.
我们之前已经尝试过Abode ，它也是一个很棒的DIY安全系统。 它也比ADT便宜。
A package similar to what you’ll get with ADT and SimpliSafe cost $408 up front, and comes with three door/window sensors, a motion sensor, a keypad, and a keychain remote. As for the monthly fee, the $30/month plan comes with 24/7 professional monitoring, but if you pay up front for a whole year, you can get it for $20 per month.
With that said, the total cost of Abode over three years would total $1,228—$778 cheaper than ADT and just a bit more than SimpliSafe.
您可以在没有专业监控的情况下使用DIY系统 (You Can Use a DIY System Without Professional Monitoring)
A huge plus with SimpliSafe, Abode, and other DIY systems is that you can use them without paying for the monthly professional monitoring fee. Of course, with SimpliSafe, it’ll be nothing more than a loud noise machine to scare off burglars, but it’s better than nothing. Abode, on the other hand, allows for self-monitoring in the app.
SimpliSafe，Abode和其他DIY系统的一大优点是，您无需支付每月的专业监控费即可使用它们。 当然，使用SimpliSafe，它无非是一声大声的机器来吓跑小偷，但总比没有好。 另一方面，Abode允许在应用程序中进行自我监控。
With ADT, you can’t use the system without paying the monthly fee. Or at least that’s what they tell you and try to enforce—it’s possible to use an ADT system without paying the monthly charge, but there’s a bit of a workaround in order to make that happen, and you lose a bit of functionality.
使用ADT，您必须先支付月费才能使用该系统。 或至少是他们告诉您并尝试执行的内容-可以使用ADT系统而无需每月支付费用，但是要做到这一点有一些解决方法 ，您会失去一些功能。
If you have a smarthome system like Wink or SmartThings, you can use it as a security system and even receive alerts on your phone when there’s a possible intruder. This won’t cost you anything extra per month, and it’s a bit of a step up from just being a loud noise machine. You also have a lot more flexibility when using smarthome platforms, as you can also take advantage of automation and use your sensors to do all kinds of cool stuff.
如果您拥有Wink或SmartThings之类的智能家居系统，则可以将其用作安全系统，甚至在有可能的入侵者时在手机上接收警报。 这每月不会花费您任何额外的费用，并且比仅仅是一台响亮的噪音机器要高出一个台阶。 使用智能家居平台时，您还具有更大的灵活性，因为您还可以利用自动化的优势，并使用传感器来做各种很酷的事情 。
技术基本相同 (The Technology Is Mostly the Same)
So a DIY security system like SimpliSafe is a lot cheaper and more flexible than something you could get from ADT, but surely the technology that comes with those professional systems is way better than the DIY stuff, right? Eh, kinda, but not really.
Most security systems utilize a low-power frequency for sensors and other wireless devices in the system to communicate with each other. Usually, companies come up with their own proprietary wireless protocols, but if you use something like SmartThings and Wink to build your security system around, then it can use a combination of Z-Wave and ZigBee devices.
大多数安全系统利用低功率频率使系统中的传感器和其他无线设备相互通信。 通常，公司会提出自己专有的无线协议，但是如果您使用SmartThings和Wink之类的东西来构建您的安全系统，则可以结合使用Z-Wave和ZigBee设备 。
You might argue that some of these wireless protocols are better than others, and while that may be slightly true, there’s no real huge difference—they’re all pretty reliable and have excellent range.
On top of that, the sensors and devices that come with a DIY system like SimpliSafe are no more difficult to install than an ADT system (and it’s really not that difficult in the first place). All you have to do is peel off the adhesive strips and stick the sensors on your doors, windows, etc. And the process for setting them up on the keypad interface is incredibly painless—you definitely don’t need a professional to do it.
