What is the best overall DIY home security system?
No matter where you’re located, you’ll want to protect your house and family sufficiently. So it isn’t a surprise that many turn to home security system. However, most home systems have flaws, such as the setup process being too daunting or being riddled with expensive subscriptions. For setup, the traditional option is to get a professionally installed security system. However, professional installation has high equipment costs and hefty installation fees. If you want home security on a budget, the DIY route to installing a security system might be the way to go.
Home security systems bring peace of mind to you and your family. DIY home security systems are better than ever today, bringing exceptional modularity to your home. They let you add motion sensors, outdoor cameras, full-on alarm systems and more. You’ll have to make many choices, and each will have to be suitable for your personal needs, but we’re here to help you.

A quick note about DIY: In this context, DIY means that you pick out products yourself and install them yourself, handling both the physical hardware and setup via an app. DIY systems are often wireless and may use quick installation options like adhesive. That’s not guaranteed for every system, although it’s true of many of our picks below. You won’t have to arrange for a professional to visit your home or give you a quote to take advantage of these systems, and they won’t lock you into any contract. Although the subscriptions aren’t required, they do add some useful features.

This eight-piece Ring Alarm system offers an excellent kit for smaller homes at a reasonable price, with a reliable platform that can easily connect to any Amazon Echo or Alexa devices you may have (if you choose a subscription). The kit includes a base station, a keypad for arming/disarming, four contact sensors for guarding various entry points, a motion detector and a range extender if your Wi-Fi network doesn’t quite reach the outskirts of your home where you’d like to place sensors.
Ring’s app offers a simple setup process that first-timers shouldn’t have much difficulty with. If you’d like to add other devices over time, Ring products like a Ring video doorbell or a Ring security camera will happily work with your app and may connect to the hub as well. Other smart home devices may not be as compatible — parent company Amazon prefers to keep Ring within its own ecosystem of products, so integrations with platforms like Google Assistant aren’t possible.
Finally, the Ring Protect plan offers a few extras at its lowest tier, but things get much more interesting at the $20 per month Pro plan, which adds home monitoring — making your DIY one a professionally monitored system — that can be a valuable add-on for those who want professional responses during emergencies.

The Ring Alarm Pro is similar to our top Ring Alarm pick but with a few key differences. It’s more expensive, and the primary reason is its included Eero Wi-Fi 6 router. For some people, that’s great: Wi-Fi 6 is the latest router standard that many people still haven’t upgraded to, and you don’t have to worry about choosing a new router separately. For others who have a preferred router brand or already have a Wi-Fi 6 router, the Pro package presents a problem, because some features won’t work without this particular router.
Otherwise, the Pro system includes a keypad, four contact sensors and a motion sensor as well as an alarm range extender (although the kit doesn’t include alarm sensors so you’ll need to buy these separately). Again, it’s a great package for Alexa users and those who are interested in adding more Ring or Amazon products down the road.

SimpliSafe was one of the first DIY home security systems to hit the market and is a reasonable alternative to ADT and other professional alarm company firms. That’s due in large part to its affordable cost and wide variety of accessories in comparison to most security systems. SimpliSafe makes a variety of different starter kits that usually start at around $320, and you can often get them for less through discounts.
SimpliSafe’s impressive array of accessories such as indoor and outdoor security cameras, key fob, additional motion sensors, smoke detectors, glass break sensors and siren, and its solid performance for the price makes it an easy choice. A subscription plan is necessary to get all features, and those start at around $10 per month for self-monitoring.

Arlo, the maker of one of our favorite outdoor security cameras, introduced its home security system in 2022 and it immediately stood out for its All-in-One sensors. While most home security sensors serve a single purpose such as motion or sound detection, the Arlo All-in-One sensors are capable of eight different detection functions. The sensors can detect motion and sounds such as smoke or CO alarms, plus changes in ambient light or temperature. That’s great if you have a small place like an apartment, dorm or bedroom and want quick sensor placement that can do a little of everything, anywhere.
If you want to go bigger, it’s easy to customize the system by adding Arlo cams or doorbells that will also work with the hub. You don’t need an Arlo Secure plan for basic features, but if you branch out we suggest it to get extras like video storage.

The Abode Smart Security kit is slightly smaller than our other picks, providing a hub, one mini door/window sensor, a motion sensor and a key fob. You can easily purchase separate sensor packs to expand it, and even its slimmed-down kit offers serious advantages. Notably, it’s one of the few DIY systems that works well with Apple’s Home app and Siri. That’s only the beginning of Abode’s smart home integration, which also supports numerous products from Sonos, Bose, Yale, Schlage, Philips Hue, Ecobee and many more. That makes it the perfect fit for someone who already has a family of (random) smart devices to link up.
Abode’s standard subscription plan includes video storage and enables much of that smart home integration, so we highly suggest considering it. The much more expensive Pro plan gives you professional home monitoring but not many other notable additions.

When selecting a home security system, the first decision to consider is usually whether you want a DIY or a pro system. Since you’re here, you’ve probably already decided to go the DIY route, so here are some more parameters to consider when shopping around for home security systems.
Equipment and installation
Do you just need to keep watch over your entryways? A good video doorbell for your front door and an outdoor camera covering the back may be all you need; easy to install and monitor yourself. If you want to keep closer tabs on your home inside and out with 24/7 monitoring and quick access to emergency response services, you’ll want a more robust system. Most DIY (and professional brands too) offer home security bundles with most, if not all, of the equipment you’d need to get started and the ability to add single devices as needed.
Smart home compatibility
Most home security devices are compatible with Alexa and Google Home smart hubs, but if you prefer Apple HomeKit or another smart home ecosystem, you may have to do a bit more shopping and comparing to find a system compatible with your existing smart home devices. Don’t fret over compatibility too much, as Matter will make it easier to connect previously incompatible devices.
Costs, upfront and ongoing
We listed “cost” last here for a reason. A complete home security system will likely cost you at least a couple of hundred bucks, so be prepared for that. There’s the potential to spend lots more on equipment, or a lot less; you can find cameras for under $30.
Find your budget range and compare systems in that range across brands. For a home security kit, most starter bundles fall in the same range. If you’re comfortable with self-monitoring, DIY systems may not come with any ongoing costs. Monthly subscriptions (without a contract) for cloud storage, enhanced features and possibly even professional monitoring are typically an option with DIY systems, often for lower monthly fees than professional services.
Hands-on testing is core to our evaluations of any home security products. In short, when it comes to home security systems, we pay special attention to the user experience, the promised features, reliability and overall value, along with a few other elements. We do the testing in a real home environment over at least a full week. If you want to read more about our review process, check out our in-depth article on how we test home security systems and services.
The above systems weren’t the only DIY options we explored. Here are other competitive security systems we took a look at, and why they didn’t quite make our list.
Cove: Cove’s standard lineup is fine, but its generic quality struggled to compete with our picks. If you can’t really find what you’re looking for on our list, stop by Cove to check how its kits fit.
Lorex: Lorex is an excellent home security option for those who prefer sticking with local storage. It is a bit expensive compared to other DIY systems and may require working with its somewhat clunky recorder.
Frontpoint: Frontpoint has a strong array of kits, but like ADT, its massive home monitoring fees (starting at $50) are too difficult to recommend.
Kangaroo: Kangaroo has budget-friendly systems but struggles with design quality. If you want to save as much money as possible, you may want to give it a try.
Wyze: Wyze offers a great starter home kit, but its current security flaws keep it off our list for now.
