Let’s dive right in.

Overview of SimpliSafe and ADT

SimpliSafe and ADT are both highly rated, have extremely positive reputations, and are trusted by hundreds of thousands of homeowners (in ADT’s case, millions). Despite Accomplishing the same goal of keeping people safe, SimpliSafe and ADT are very different from each other.

Here are the high-level facts about each company that you need to know:


  • Founded in 2006 in Boston, MA.
  • Manufactures their own security equipment that customers purchase and own for life.
  • Do-it-yourself installation.
  • All equipment is connected wirelessly, which makes installation simple and easy.
  • No contracts or commitment.
  • Monitoring fees are lower than ADT, starting at $15 per month.
  • Ability to control the system via a mobile app.
  • The most common complaint is that the system can temporarily lose cellular connection, which disables monitoring.
  • You can build your SimpliSafe system and buy it online at SimpliSafe.com.
SimpliSafe Home Security System


  • Founded in 1874.
  • The largest security company in the US and Canada and known as the industry leader.
  • Customs lease the equipment, which lowers the upfront cost, but monthly fees are higher.
  • The system can be hardwired into your home with wireless backups or can be set up as wireless-only.
  • Professional installation is required. ADT sends a technician out to your house. Self-installation is not an option.
  • ADT requires a monitoring contract that starts at $28.99 a month but is typically closer to $48 a month, depending on your package.
  • They require you to commit to a two or three-year contract.
  • Top of the line features including remote monitoring and family location via mobile apps.
  • The most commons complaints are around the lack of pricing transparency (they won’t give you a price until a rep comes out to your house), very aggressive salespeople, and mandatory long-term commitments.
  • You can request a quote for ADT by calling them: 855-447-0762.

Company History

SimpliSafe is a relatively new company focused on innovation, transparency, and ease, while ADT has been around for over a century and prides itself on its legacy and scale.

SimpliSafe was founded in 2006 by two Harvard Business School classmates. They launched their first product in 2009 and grossed a little over a million dollars in the first year. Since then, they’ve grown exponentially and have taken on investment from high profile venture capital firm Sequoia Capital.

In early 2018, they released the third generation of SimpliSafe, which features smaller and sleeker sensors and updated features. They brand themselves as the modern innovative home security company and appeal to busy professionals with their fast and straightforward do-it-yourself installation, hence the name SimpliSafe.

ADT’s history is quite the opposite of SimpliSafe. It was founded over 140 years ago in 1874. It started as a telegraph-based alert system and evolved over the decades to become the largest home security company in the United States and Canada.

ADT has gone through several mergers and acquisitions and, most recently, was bought in 2016 by Apollo Global Management for almost 7 billion dollars. They still operate under the brand ADT. They use their legacy and scale to brand themselves as the most trusted security company.

Product Offerings, Packages, and Options

SimpliSafe gives you two ways to choose your system. You can decide to build it yourself by picking exactly what sensors, monitors, detectors, and alarms you need. Or, if you’re not exactly sure what you want, they offer packages that include unique options based on typical customers’ needs.

Every SimpliSafe system starts with a Wireless keypad, which is what you use to control the system and a Base Station, which connects each component and communicates with the monitoring centers.

SimpliSafe offers the following to build your system:

Burglary sensors

  • Entry sensors to protect doors and windows.
  • Motion sensors to detect human movement when you are away.
  • SimpliCam, which you can monitor on your mobile device and get alerts when motion is detected.
  • Glassbreak sensor which can differentiate the sound of broken glass from the sound of a broken plate.
  • Panic button which you can press to immediately dispatch police if you are home during a break-in.

Hazard sensors

  • Smoke detectors with deafening sirens.
  • Carbon monoxide sensor.
  • A temperature sensor that alerts you when your home falls below 41 degrees Fahrenheit to prevent pipes from freezing.
  • Water sensors to detect leaks and alert you before a small issue becomes major.

Optional extras

  • Extra keypad if you use multiple doors to enter and exit your home.
  • Keyfob to disarm your alarm before entering.
  • Extra sirens that you can place inside or outside.
  • Extra yard signs to scare off intruders.

Similar to SimpliSafe, ADT offers packages that include all the basics like a keypad, motion detectors, door and window sensors, glass break sensors, keyfob with a panic button, and more.

ADT offers three packages, the Traditional, Control, and Video.

The Traditional package includes the following:

  • ADT Go Family Locator App, which features crash detection and family location monitoring, so you always know their location and that they are safe.
  • Cellular Connection which allows you to connect your system to the monitoring center via a cellular signal rather than through your landline.
  • Fire, Carbon Monoxide & Flood Monitoring sensors that send an immediate alert to you and the monitoring center.
  • 24/7 Monitoring to quickly respond to emergencies around the clock.
  • 6-Month Money-Back Guarantee gets you a full refund of installation and monitor costs if you cancel within 6 months.

The Control package includes everything in the Traditional package plus:

  • Home Automation. With the ADT Pulse app, you can control lights, locks, thermostats, and more right from your phone.
  • Email & Text Alerts when any of your sensors are triggered.
  • Remote Arm/Disarm Via Mobile App and never worry if you turned the alarm since you can arm or disarm it via your phone.

The Video package includes everything in the Traditional and Control packages plus you can view live video from your security cameras on your phone. You can also playback clips of the moments that your sensors are alerted.

Purchase Process

ADT offers extra features that SimpliSafe does not, including smart home connectivity and the family locator app. Still, the main difference between ADT and SimpliSafe products are not the products themselves. The main difference is in the way that you buy them, and the transparency throughout the process.

With SimpliSafe, you can go directly to their website, build a package, and see the price of each component right in front of you (see a screenshot from SimpliSafe.com below). You buy and own the equipment for life.

SimpliSafe pricing online

When you got to ADT.com and try to see pricing for each package, you get a message that asks you to fill out a form to be contacted.

ADT get a free quote

ADT requires you to schedule an appointment with a rep who will come to your house, assess your situation, and provide a quote for the package they recommend. The pricing depends on the package you choose and the needs of your home.

Unlike SimpliSafe, which is sold direct to consumers, ADT systems are sold through independent dealers. These companies are contracted to sell and service ADT. You can find out who the dealer is closest to you on ADT.com.

The dealers are compensated based on sales, so, as you can imagine, once they get in your house, they sell aggressively and make it difficult to say no. In most cases, this is not a problem, but like any product sold through independent dealers like this, your experience will depend on the particular dealer you get.


One of the most significant differences between SimpliSafe and ADT is how each system is installed.

SimpliSafe is a do-it-yourself installation. It comes with a USB drive that gives you very clear, step-by-step instructions on how to install. Every component is wirelessly connected, so there is no electrical work necessary. Depending on the number of sensors and monitoring devices, it can take from 20 minutes to an hour to install.

ADT is installed by professionals. When you purchase the system, they will schedule an installation appointment. It usually takes two to three hours, depending on the package you are buying and the size of your home. The installer will be able to explain how everything works in detail and answer any questions you have. Despite being less convenient, with ADT, you get a personal touch that you don’t get with SimpliSafe.    

Monitoring Options and Contracts

ADT requires all customers to sign a 3-year contract (besides California, where they only require a 2-year contract) that includes 24/7 monitoring. The Traditional package is $28.99 per month. The Control package is $36.99 per month. The Video package is $52.99 per month.

The one really interesting advantage for ADT is that they can plug their monitoring into an existing home security system. So if you move into a house with a system from another company installed, you can set it up with ADT monitoring.

With SimpliSafe, you have more flexibility. You have the option of not having monitoring at all. If you decide to not pay for monitoring, your sensors will set off the siren to alert you and hopefully scare off intruders, but the system will not contact the monitoring center or authorities.

If you decide to purchase monitoring from SimpliSafe, you have two options.

  • Standard, which costs $14.99 per month and gets you 24/7 connection to a monitoring center that will be alerted whenever an event such as a break-in, fire, or broken glass, is triggered in your system.
  • The other option is called Interactive, which costs $24.99 per month and gives you more control and the ability to arm or disarm from your phone, get mobile alerts, get unlimited camera recording, and integrate with smart home systems such as Alexa, August Locks, and Nest.

A significant advantage of SimpliSafe is that they don’t require you to commit to a contract. You can cancel the monitoring service at any time with no issues.

Price Comparison: Short-Term and Long-Term

To accurately compare pricing between SimpliSafe and ADT, you have to look at the short and long-term costs and also consider the cost of equipment, installation, and monthly monitoring fees.

First, let’s look at SimpliSafe.

Equipment – The cost of equipment depends entirely on what you get. Systems start at $200 but could easily run you over $600, especially for homes over 2000 square feet. On average, customers invest about $500 in equipment. You have the option to save 25-30% by purchasing certified refurbished equipment on SimpliSafe.com.

Installation is free since you are doing it yourself.

Monitoring – $14.99 per month for standard monitoring and $24.99 for Interactive monitoring.

The total cost for the first year of SimpliSafe will be approximately $680 with Standard monitoring ($500 for equipment and $180 for monitoring) and $800 with Interactive monitoring ($500 for equipment and $300 for monitoring).

Over three years, the total cost of SimpliSafe will be approximately $1,040 with Standard monitoring ($500 for equipment and $540 for monitoring) and $1,400 with Interactive monitoring ($500 for equipment and $900 for monitoring).

In general, the upfront cost of ADT is less than SimpliSafe. There is technically no equipment cost because, with ADT, you are either using existing equipment or leasing it from them. Unlike SimpliSafe, ADT charges a set-up fee.

ADT offers three packages, the Traditional, Control, and Video. With each package, you can add features and customize it to fit your exact needs, but be aware that the activation cost can increase will each addition.

ADT’s Traditional package costs $125 for set-up and $28.99 per month. Over a year, this will cost you $473. Over three years, it will cost $1,169.

The Control package costs $125 for set-up and $36.99 per month. In one year, this package will cost you $569 and in three years, $1,457.

The Video package costs $125 for set-up and $52.99 per month. The first-year cost is $761. The three-year cost is $2,033.

To summarize, SimpliSafe will cost between $680 and $800 in the first year and between $1040 and $1400 for the first three years. ADT will cost between $473 and $761 in the first year and between $1169 and $2033 for the first three years.

Although the prices are not significantly different, consider that you will likely be in your home and want to have home security for more than 3 years. Because of the higher monthly fees, SimpliSafe is the clear winner in price.

Advantages and Disadvantages

SimpliSafe is an up and coming home security company that prides itself on taking the complexity and stress out of home security.

Here are SimpliSafe’s key advantages:

  • Complete transparency from the beginning on what you are buying and how much it will cost you long term.
  • Low monthly fees that will save you thousands long term, assuming you are planning on keeping your home secure for life.
  • No contracts.
  • Do-it-yourself set up is simple and easy, so you can avoid scheduling appointments and dealing with aggressive sales reps.

SimpliSafe has some disadvantages that you should be aware of, such as:

  • Higher up-front cost to purchase the equipment compared to ADT.
  • Lack of personal touch since no one is there to explain to you how each component works. This issue is mitigated by their clear instructions and customer service center that you can reach via phone.
  • Some customers complain that their signal gets lost, and they lose connection to the monitoring center. I’ve had this happen to me, which I explain in detail in my in-depth review of SimpliSafe.

ADT is the Goliath in the home security space and has built its strong reputation over 140 years in the business.

Here are the advantages of ADT:

  • Low or no equipment costs.
  • Professional installation that only takes a few hours and allows you to ask questions in person.
  • Long legacy and strong reputation as the industry leader.

ADT also has some disadvantages, such as:

  • Higher monitoring fees and three-year contracts.
  • Limited price transparency until a rep comes out to your house.
  • Some sales reps can be aggressive to make a commission.

Verdict: Which Home Security Option Is Best for You?

Both SimpliSafe and ADT are always innovating and coming out with new products and services, but their core offerings are very similar. The differences are in how you buy (yourself online vs. talking to a rep), how it is installed (DIY vs. professional), monitoring contracts (low cost without contracts vs. higher cost with contracts), and long-term price.

If you are comparing purely on price and can afford to pay around $500 upfront for equipment, SimpliSafe will save you a lot in the long run due to their low monitoring fees.

If the price is not as important, SimpliSafe is an excellent option for people who are comfortable setting up the system themselves. ADT is best for those who would rather have a professional do the work.

Personally, the price was the most significant factor, so I decided to go with SimpliSafe.

Whichever one you choose, you’ll be getting a high-quality system that will keep your family safe, and that’s the most critical part.

  1. I’ve been an ADT customer for about 30 years. ADT bills itself as a premium company, yet they are overpriced and their customer service stinks. I have a house with an OLD ADT alarm. Still works as it should. However, it has no advanced features and yet still costs me nearly $60/mo. Not too long ago, I had a rare accidental activation. I tried to call ADT to cancel the police response and sat on hold for 15 minutes until the police arrived. All they provide me is someone to call the police if my 30 year old alarm activates. This system does nothing more and neither does ADT. $60/mo. is way too much for that and bad customer service.

    I just ordered a SimpliSafe system to replace the ADT Safewatch system. I already installed one of these for a relative and it works great. I’ll be glad to send the cancellation to ADT shortly.

    • Hi Mike,

      Thanks for sharing your experience with ADT. Base on my experience with SimpliSafe, I think you’ll love it.

      Best of Luck!
