ADT and SimpliSafe occupy the top two positions on our list of best home security systems. While they’re both great systems with top-tier equipment and monitoring, they do things differently. Ultimately, we feel like ADT has the edge, but SimpliSafe has a lot of positives of its own, and for many homeowners, it’s going to work best.
In the past, ADT exclusively offered white-glove service from installation to monitoring, whereas SimpliSafe offered full DIY security. Things have changed recently, though. ADT now offers DIY installation and self-monitoring. Ironically, SimpliSafe now offers professional installation and advanced monitoring options.
The good news is that you really can’t go wrong in terms of safety and security with either. Both companies are among our favorite security systems. If you really care about your home security, though, you want to pick the system that’s exactly right for you. The only way to do that is to compare them side-by-side.

We were able to fully protect the interior of our home with our six-piece SimpliSafe security system.
SimpliSafe vs ADT: An Overview of Two Top Home Security Systems
Before we go any further, let’s get one thing out of the way: ADT and SimpliSafe both offer great home security systems. They’re two of our favorite providers, so you really can’t go wrong with either. That said, they take two different approaches to home security, although they’ve grown more similar in recent years.
ADT’s strengths start with its 150 year history leading the industry. They still offer the best professional installation and monitoring. Plus, they offer an industry-best six-month money-back guarantee. All that hasn’t stopped them from continuing to innovate. Most recently, they partnered with Google to integrate with Nest devices.
SimpliSafe hasn’t been around as long as ADT, but they made a splash on the industry with the first DIY system for renters. They’ve expanded their offerings since, and can now protect everything from a studio apartment to a mansion. They even offer advanced monitoring with active deterrence that give advanced systems like Vivint a run for their money.
And just like that, a serious rivalry was born.
For more targeted information on each brand, you might start with our hands-on SimpliSafe review, which includes a look at their newest equipment. To learn more about ADT, have a look at our in-depth ADT review.
But enough about these two companies in isolation. Let’s talk about how they compare to one another.
A Quick Point-by-point Comparison of ADT and SimpliSafe
ADT and SimpliSafe are different systems. They offer different equipment, different monitoring plans, and they operate on different philosophies. Even so, there are a number of striking similarities – more and more all the time.
Before we dig into their differences, let’s cover what they have in common.
- Quality Hardware – Both ADT and SimpliSafe offer reliable, wireless equipment. SimpliSafe manufactures their own equipment which keeps their costs low. ADT uses GE and Google Nest equipment which is the highest quality we’ve tested, but it comes with a higher price.
- Smart Home Automation – Both SimpliSafe and ADT equipment work well with Alexa and Google Home. They also both work with a few other third-party smart products like August smart locks. As a Google partner, though, ADT has a slight edge with Google devices.
- Monitoring Services – ADT and SimpliSafe offer some of the best professional monitoring services in the industry. ADT operates 12 redundant monitoring centers with average response times of under 30 seconds during our tests. Meanwhile, SimpliSafe offers active monitoring where their agents can use your cameras’ two-way talk to deter crime.
- Smartphone Controls – Both companies offer responsive mobile apps that let you access and manage your system remotely using your smartphone. ADT's newly redesigned ADT+ app beats SimpliSafe’s by a hair. That said, we still found SimpliSafe's app well-designed and easy to use.

Here’s a look at the ADT+ app from when we tested an ADT Self Setup system in our home.
- Environmental Protection – While both of these brands provide outstanding protection from break-ins and burglaries, they also offer features that can keep you safe from environmental dangers, like smoke, fire, carbon monoxide, and flooding.
- Cellular Monitoring – To ensure a fast connection, both systems now use 4G LTE cellular backup. This ensures your system stays connected during internet outages with fast enough speeds to stream footage from your cameras.
- Installation – Both ADT and SimpliSafe let you choose between self-installation and professional installation. There’s no question, ADT wins when it comes to professional installation. It’s hard to beat 150 years of experience. For self-installation, we like SimpliSafe slightly more, although we were impressed when we tested ADT Self Setup.
- Costs & Fees – SimpliSafe used to be a lot more affordable than ADT, and generally, it is still slightly more affordable for comparable systems. However, their prices have become so similar that if ADT’s running a good sale, it can end up costing less.
- Contracts – ADT used to require contracts, but their Self Setup systems are available with a month-to-month plan. In contrast, SimpliSafe never requires a contract. In contrast, SimpliSafe doesn’t require you to sign a contract at all. With SimpliSafe, you just pay for your equipment and then month-to-month for any monitoring services. However, keep in mind that SimpliSafe lets you finance equipment. Do that, and you’ll wind up with a contract through Affirm, their third-party financing partner.
FYI: SimpliSafe offers affordable monitoring plans — which start at just $21.99 per month. The industry averages $30 to $50 per month. There’s also the option to pay only for video storage at about $10 per month, or not pay at all.
- Money-Back Guarantee – Both companies offer a money-back guarantee that gives you a good amount of time to test your system out before committing. Most companies offer 30 days. SimpliSafe offers double that number – 60. Impressive. But no one outdoes ADT. They offer an industry-best six month money-back guarantee.

The command strips on the back of SimpliSafe’s sensors made them easy to install.
Did You Know? ADT requires long-term contracts with most systems, which helps to spread the cost over years. You can avoid the contract with a full-priced DIY-installed system. SimpliSafe requires that you purchase the equipment upfront, which means you own it and don’t have to worry about contracts or ongoing charges. They now offer financing through a third-party, Affirm, though. Both brands do charge for monthly monitoring.

SimpliSafe Costs
If we look at regular retail prices, SimpliSafe’s pricing is on par with ADT. The most expensive package, the “The Beacon” package, costs $729. But the thing is, SimpliSafe packages are always on sale. You’re almost guaranteed to find discounts at least 20 percent (but sometimes up to 70 percent). And with these discounts, SimpliSafe is way more affordable than ADT.
It’s also true that SimpliSafe offers more affordable monitoring options than ADT. Basic professional monitoring, SimpliSafe’s Standard plan, costs around $22 a month, $3 cheaper than ADT’s basic plan. SimpliSafe’s Core plan, which includes access to camera storage, costs $32 a month, or $8 cheaper than what ADT charges.
However, SimpliSafe’s monitoring plans range up to $79.99 per month. The top-tier plans include SimpliSafe’s groundbreaking Active Guard Outdoor Protection. It allows SimpliSafe’s agents to scare off potential intruders using the outdoor camera’s built-in spotlight, two-way audio, and siren when the camera’s AI detects a threat. That’s something not offered in any ADT plan.
Pro Tip: SimpliSafe is always running deals on their home security equipment packages, particularly around the holidays.

Installation
Here again, these two systems have grown more similar, though there remain some important differences.
Installation for ADT Security Systems
Even though ADT now defaults to their DIY installation option, we’re still big fans of their professional installation. It costs $99 to $199 depending on the size of your system, but we think it's worth the fee. Having your system professionally installed ensures all components are placed in their optimal location, improving overall performance.
That said, ADT's Self Setup option is solid. All of the equipment is easy to install with step-by-step instructions provided by the app. You don’t even need to go it alone. ADT offers virtual assistance where a tech guides you through the installation over the phone.
Installation for SimpliSafe Security Systems
When you go with a SimpliSafe system, you’re going to be installing it yourself. You can pay for professional installation which starts at $125, but it’s so easy to install that we don’t recommend it. That means you don’t have to worry about scheduling a time for a tech to visit or worry about any extra fees.
SimpliSafe’s wireless equipment makes DIY installation super simple — all you have to do is set up your base station and place your equipment where you need it. The only thing that requires wiring is the Video Doorbell Pro which uses the same wiring as your current doorbell. Just make sure to read our guide to SimpliSafe Installation to make the process as seamless as possible.
How Do I Know Which Security System Is Best for Me?
When it comes to keeping your home safe from intruders, it’s tough to go wrong with either system. However, these two manufacturers really do target different living situations and budgets. If you’re looking for something easy-to-use, highly customizable, and affordable, go with SimpliSafe. If you’re looking for total home protection that you won’t have to lift a finger for (and don’t mind shelling out cash for), ADT is probably more your speed.

Why Choose SimpliSafe?
In the long run, you can save a lot of money with SimpliSafe. First, with SimpliSafe you are not obligated to pay for professional monitoring fees. However, if you want the monitoring services, SimpliSafe offers extremely affordable fees (starting at $21.99 per month). Also, with SimpliSafe, you don’t have to worry about installation fees and cancellation fees. On a last note, SimpliSafe manufactures its own equipment, which also helps you save money on the equipment because there are no middlemen to jack up the prices.

Why Choose ADT?
ADT excels in providing comprehensive, professional-grade security with flexible payment options. Their new no-contract Self Setup systems eliminate the traditional barrier of long-term commitments. With it, you still get access to ADT’s renowned monitoring network and the same high-quality equipment.
Most recently, ADT started offering Google Nest products as part of their security system. These add advanced facial recognition capabilities that power ADT’s Trusted Neighbor feature. This can genuinely improve the safety of your home. However, overall, ADT costs slightly more than SimpliSafe and they lack any active monitoring capabilities.
FAQs
- Can I finance my SimpliSafe system like I can with ADT?
Yes, you can now finance a SimpliSafe security system. But, it’s not directly through SimpliSafe like it is with ADT. You’ll finance the equipment through Affirm.
- How do I avoid signing a long-term contract with ADT?
ADT now offers multiple no-contract options through their Self Setup line — simply purchase the equipment outright and choose month-to-month monitoring. Professionally installed systems still require a long-term contract.
- Who has better equipment, ADT or SimpliSafe?
Generally, we like ADT’s equipment more, but SimpliSafe’s equipment is more affordable.
- Does SimpliSafe or ADT charge more for professional monitoring?
ADT's monitoring ranges from $24.99 to $44.99 monthly, while SimpliSafe's plans range from $21.99 to $79.99 per month. For comparable features, SimpliSafe typically costs less—their $31.99 Core plan matches ADT's $39.99 Complete plan for most features.
- Can I customize an ADT or SimpliSafe system?
Yes, both providers let you build out a completely custom system. You can purchase their packages as a starting point and then add equipment from there.
