Xfinity vs. ADT: Comparing Two High-Tech Security Systems

When it comes to home security, you have a lot of options. Do you want a top notch DIY system, or would you prefer a more traditional, professionally monitored approach? Do you need high-tech smart home automation, or are you content with something a little more basic?

Each approach can be beneficial. With ADT, you can be sure you’re getting top-notch security service because that’s its specialty. With Xfinity, you can bundle multiple home services together to enjoy savings and the convenience of paying for all those services in one place.

Here’s the thing: both ADT and Xfinity bring something unique to the table. ADT has been protecting homes since 1874 and that experience shows. Xfinity, while newer to security, leverages its vast network infrastructure to offer competitive pricing and bundle deals.

I’ve been testing and reviewing security systems for years, and have personally worked with both Xfinity and ADT in my own home. I think that uniquely qualifies me to put these two systems side by side and give you the lowdown on which one comes out ahead. By the end of this comparison, you should have a pretty good idea of what these systems are capable of, what it’s like to use them day to day, and ultimately, which one would be the right choice for you.

The Key Similarities of Xfinity and ADT

When you remove all the other factors and just focus on their home security offerings, Xfinity and ADT are actually quite alike. Take a look at these key similarities between Xfinity and ADT security systems:

• Expert installation: Both brands offer expert installation so you can kick back and relax as your system is installed for you. After the installation, you will get a one-on-one tour of your new system.
• Professional monitoring: You can also count on both Xfinity and ADT to watch over your home. Through professional monitoring, both brands will respond to alerts 24/7.
• Home automation: ADT and Xfinity are both home automation experts. With ADT, you can link up your home automation devices via Z-Wave and integrations with Alexa and Google Assistant. With Xfinity, you can control your security system with your TV remote thanks to X1 smart remote.
• Security cameras: Xfinity and ADT both offer security cameras to further boost your home security. Their cameras can stream live to your phone, record and playback important events, and store footage in the cloud.
• App access: Lastly, both security systems are app-centric. You can use an app to arm and disarm your system, set up custom alerts, control home automation devices, and so much more.

The Key Differences of Xfinity and ADT

But Xfinity and ADT aren’t all that alike. They have some differences, too, and you might want to pay attention to these differences as they are the biggest factors that can sway your decision:

• Monitoring options: Although Xfinity recommends professional monitoring (as do we), you can self-monitor a security system from it. This is not possible with an ADT system.
• Availability: ADT offers security systems and monitoring pretty much everywhere in the United States, but with Xfinity, home security products and services are not available in some areas.
• Contract: Professionally installed ADT systems typically require a three-year monitoring contract. Xfinity’s contracts are month-to-month, which means you can cancel anytime without extra fees or penalties.
• Cellular monitoring: ADT uses cellular monitoring, currently the most reliable type of monitoring. Cellular-based security systems send alerts through cellular signals, the same type of signal our phones use to send texts. With Xfinity, your security system will rely on your Wi-Fi signal and internet connection.
• Continuous video recording (CVR): Not a lot of security cameras record continuously, but Xfinity’s cameras do if you’re on the highest-tier monitoring plan or Xfinity’s paid self-monitoring plan.

Do any of these features stand out for you? If not, don’t worry, because we’re zooming in on the smaller details to give you a side-by-side comparison of Xfinity and ADT.

Equipment Comparison

If a high-tech, wireless security system is what you’re after, you have options from both Xfinity and ADT. That being said, their equipment options differ slightly.

Xfinity Equipment

With Xfinity, your security system starts with a Wi-Fi router. Yes, you read that right: a router. The xFi Gateway is at the heart of every Xfinity system. Besides connecting you to the internet, this router connects your security system to Xfinity’s monitoring network.

You’ll still get a touchscreen keypad, though, which will serve as your security system’s control panel. You’ll also receive an extra push-button keypad with some bundles.

When it comes to sensors, Xfinity’s options are a bit limited. You can get entry sensors, pet-friendly motion sensors that can ignore pets up to 80 pounds (making it a good security system for pet owners), and smoke detectors. Other than those, the rest of Xfinity’s equipment consists of security cameras and smart home devices.

Head over to our Xfinity review for a closer look at Xfinity’s equipment options.

ADT Equipment

ADT security systems center around the ADT Base, a sleek hub with a touchpad that acts as your system’s command center. It connects to the internet and has a cellular chip for communication. It also wirelessly pairs with all ADT sensors and components. You can learn more about it in our in-depth ADT security system review.

Beyond the Base hub, ADT offers an impressive array of sensors to protect against both intrusion and environmental hazards. These include motion sensors (which are also pet-friendly), entry sensors, glass break sensors, smoke detectors, carbon monoxide detectors, and flood sensors.Additionally, ADT offers security cameras for indoor and outdoor use, as well as video doorbells. And when it comes to home automation, ADT offers smart thermostats, smart locks, smart appliance modules, and smart lights, among others.

Equipment Winner

Although Xfinity’s equipment looks more modern than ADT’s, we like the variation of ADT equipment. ADT offers more types of sensors, and when it comes to securing your home, more options means more ways to detect intrusion.

Monitoring Comparison

Aside from security equipment, both ADT and Xfinity offer monitoring options. Let’s check out what monitoring services you can get from both companies.

Xfinity Monitoring

Xfinity currently offers two monitoring plans: the Smart Home Plan and Home Security Plan. Let me break down what you get with each:

The Self Protection Plan is a self-monitored plan, which means your Xfinity system will not be linked to a monitoring center. However, it has a monthly fee because it stores up to seven days of continuous video from up to six cameras.

The Pro Protection Plus plan, on the other hand, is professionally monitored. It also comes with cloud storage for continuous video recording, and doesn’t require a contract. You can downgrade your plan at any time, and you won’t have to pay any cancellation fee if you decide to go with another provider.

ADT Monitoring Options

With ADT, professional monitoring is mandatory for professionally installed systems. You can self-monitor Self Setup systems for free, but there isn’t a dedicated plan for it. For monitoring, you’ll choose from three tiers: Secure, Smart, and Complete.

The Secure plan provides basic professional monitoring without app access or smart features. The Smart plan adds remote control via the ADT+ app and home automation capabilities. The Complete plan includes everything plus full video monitoring with cloud storage and playback features. Note that prices are $10 more per month across the board for professionally installed systems.

ADT plans also come with a contract for three years if you had your system professionally installed. This contract locks you into the service, so while it’s active, you can’t cancel your subscription. Otherwise, ADT reserves the right to charge you for the remaining months of your contract.

Monitoring Winner

Like we mentioned earlier, we like having options. And this time around, Xfinity offers more choices. You can choose between self- and professional monitoring, and you can even switch subscription plans as needed because there are no long-term contracts involved.

Installation Comparison

It’s pretty much a tie between ADT and Xfinity in terms of installation. With both brands, experts came to our home to install the system for a fee. This service is required, and the fee is about $100 for both companies.

I’ll give ADT credit for exceptional service quality. The technician didn’t just install equipment — they walked through our home to identify optimal sensor placement, explained every feature thoroughly, and made sure we were comfortable using the system before leaving. I scheduled installation on Tuesday and they arrived Wednesday morning, right on time. ADT promptly set us up with a working security system. We guess that’s why ADT is one of the best professionally installed security systems around.

Cost Comparison

Next comes one of the biggest deciding factors most people consider when choosing which security system to buy: cost. We’ll be comparing the costs of Xfinity and ADT equipment, monitoring, and installation.

Equipment Cost

Xfinity has prepackaged equipment bundles available for interest-free installments. These bundles are the Base Home, Complete Home, and Ultimate Home systems. Xfinity’s pricing for these sets range from $360 to $600.

You can also buy add-on sensors and components, but again, there aren’t many options.

ADT offers fully customizable packages that you can tailor to your home’s specific needs. The three main packages — Security Starter, Video Essentials, and Total Safety — provide different starting points depending on your priorities.

You can add a wide range of devices to your system, and these add-ons can be included in your financed equipment cost as well. For example, you can add extra entry sensors for $20 each or, if you choose the three-year financing plan, an additional $0.56 to your monthly installment.

Monitoring Cost

As discussed earlier, both Xfinity and ADT offer three monitoring options. With Xfinity, professional monitoring starts at $45 per month (the $10-per-month plan is a self-monitored plan). With ADT, however, the cost starts at $24.99 per month. That’s actually a $20 difference in ADT’s favor. However, Xfinity’s $45 plan includes smartphone app access and basic home automation features that ADT’s basic plan lacks.

If we compare the highest subscription tiers from both brands, Xfinity comes out as the more practical option as well. At $45 per month, the Pro Protection Plus plan offers seven days of continuous video recording for up to six cameras. With ADT, the Complete plan, which costs up to $49.99 per month, records only when motion is detected.

Keep in mind that Xfinity’s advertised rates require enrollment in autopay and paperless billing. Skip these options, and you’ll pay an extra $10 monthly, bringing Xfinity’s pricing closer to ADT’s standard rates.

Installation Cost

As for the installation cost, the standard service fee for both brands is around $100, but it’s worth mentioning that ADT often has deals that could waive the installation fee. There are online deals that can save you a percentage of your equipment cost, free equipment offers, and more. In the end, you could end up not paying for installation if you take advantage of these ADT deals.

Cost Winner

Looking purely at the numbers, Xfinity takes the win for affordability. Equipment packages run $360 to $600, and professional monitoring stays at a flat $45 monthly with the right billing setup. But here’s what caught our attention: ADT now offers more flexible payment plans. You can spread equipment costs over 36 months, making that initial investment easier to manage.

Who Wins Overall?

In the end, the best security system for you is the one that can meet your security needs with the right equipment, solid and reliable monitoring, quality installation, and pricing that falls within your budget. Xfinity and ADT can both be that.

After testing both systems extensively, we give the edge to ADT for overall security performance. Yes, it costs more and requires a longer commitment, but ADT brings unmatched reliability to the table. With redundant monitoring centers across the country and cellular backup that works even when your internet goes down, ADT delivers peace of mind that’s hard to beat.

ADT is not a perfect system, of course, especially if you’re on a budget or if you see yourself moving within the next couple of years. ADT is a tad more expensive than most options, and the contract can really be a deal-breaker for some. If you think neither Xfinity nor ADT is right for you, you can explore other options mentioned in our list of the best home security systems.
