Age and Influence 

Xfinity Xfinity is a division of Comcast, a major broadcasting conglomerate that rakes in $10+ billion yearly. Comcast is huge, to say the least, and has been in business for 55+ years. But Xfinity Home Services, the division that brings us Xfinity home security, was only recently added in 2011. At any rate, Xfinity’s security offerings are growing in popularity. But can they compete with the gold standard in home security, ADT?

ADT ADT has been the biggest player in home security since the beginning. The company has 18,000 employees, 7 million customers, and priceless brand recognition. ADT isn’t as big as Comcast in terms of revenue, but the name ADT is almost synonymous with ‘home security’. In other words, the influence of ADT is not to be understated.

Age and Influence Category Winner: ADT

ADT has the edge over Xfinity when it comes to age and influence. And the reason is simple. ADT has been innovating home security solutions for 150 years, whereas Xfinity entered the market less than a decade ago.

Features and Technology 

Xfinity — Xfinity Home is all about smart security and automation. The advanced features and technology are enough to satisfy most users. And they range from 24/7 monitoring to night vision cameras, smart home integrations, and environmental devices.

Standout Xfinity features and tech include

  • 24/7 professional monitoring
  • Mobile access & control via Xfinity Home app
  • Zen Thermostat and other smart devices
  • Seamless integration w/ third-party platforms
  • Custom home security and automation rules
  • Television controls (for Xfinity X1 subscribers)
  • Environmental monitoring (Maintenance-free smoke detector)

ADT — The home security giant ADT is known for offering nearly endless features and technology. However, the add-on upgrades can ring up quite the tab if you’re not careful. ADT security delivers big on features & tech such as home automation, remote access and control, smart motion detectors, and more.

Standout ADT features and tech include:

  • Landline and cellular systems
  • 24/7 monitoring
  • Extensive home automation capabilities
  • Smart environmental monitoring
  • Pet-friendly motion sensors
  • Nifty mobile app for remote access/control

Features and Technology Category Winner: Tie

Both ADT and Xfinity have a lot to offer when it comes to new features & tech. They combine total home security with smart automation, allowing you to protect your family and make life a little easier with smart devices. With that said, there is nothing groundbreaking or especially innovative about either of their offerings.

Monitoring Options

Xfinity — Xfinity delivers round-the-clock protection with 24/7 monitoring. They have one base package called Xfinity Home Secure. There is no upfront cost, and you only pay $29.99/mo. for the first year. In the second year, it jumps to $39.99/mo., which is typical for premium home security. If you are an existing Xfinity customer — or desire internet, phone service, and/or cable — Xfinity offers great deals with their bundled packages. Bundling puts everything on one convenient monthly bill. Unfortunately, Xfinity’s monitoring is limited in options.

ADT — While Xfinity only offers one monitoring package, ADT offers four packages in all. They range from $27.99/mo. for basic home security, and top out at $58/mo. with cellular connectivity, home automation, and video, you name it. While $40-$60 monthly is a touch pricey for home security, you get what you pay for in reliable professional monitoring, smart home automation, and a name you can trust.

Monitoring Options Category Winner: ADT

24/7 monitoring is crucial. It puts a hawk-eye on your home and keeps the burglars at bay. ADT simply has more options than Xfinity. However, Xfinity has an almost irresistible deal where you only pay $29.99/mo. for the first year for home security and automation. It’s a close one, but ADT gets the gold when it comes to monitoring.

Emergency Connections

Xfinity — Xfinity offers 100% wireless home security, but it does require a high-speed internet connection. The systems also offer battery and cellular backup. Many of their packages and bundles come with the required internet connection.

ADT — Most of ADT’s premium packages are cellular-based, powered by a local cell tower (like a cell phone). This type of connection is superior to landline and Wi-Fi hookups. It’s faster and more reliable. ADT also offers a super-basic hardwired landline system for only $27.95/mo.

Emergency Connections Category Winner: ADT

ADT offers cellular connectivity, and cellular-based systems are more secure and reliable than the typical Wi-Fi network. However, Xfinity’s systems get the job done just fine. So, it’s another close one.

Security Equipment Included

Xfinity — Xfinity Home comes with a small assortment of equipment. Customers get the following gear to get started: Three entryway sensors, a motion detector, a touchscreen controller (hub), and a wireless keypad for arming/disarming.

Xfinity add-on equipment includes:

  • Indoor/outdoor security cameras w/night vision
  • Zen Thermostat
  • Smart Outlet Controller
  • Smoke detector
  • Additional sensors

ADT — ADT’s basic security package includes a control panel, infrared motion sensor, entryway sensors, wireless key fob, and central security hub.

ADT add-on equipment includes:

  • Glass break sensors
  • Doorbell camera w/ two-way voice
  • Indoor/outdoor cameras w/night vision
  • Environmental sensors
  • Additional sensors

Security Equipment Category Winner: Tie

Xfinity and ADT both offer plenty of equipment for home protection. However, many customers will want to add additional sensors to their order. While the standard equipment included is a tie, let’s see how they measure up in quality. We have a clear winner in that category.

Equipment Quality

Xfinity — With the deepest pockets in the industry, you’d think Comcast Xfinity would offer the best equipment around. Unfortunately, that’s not the case. The equipment is just good enough. We’ve read several user complaints of false alarms and defective devices.

ADT — It’s no secret that ADT sells best-in-class home security equipment. In fact, unlike Xfinity, ADT’s equipment is perhaps the best in the industry. ADT’s collaborations with big-name manufacturers like General Electric and Honeywell are certainly paying off.

Equipment Quality Category Winner: ADT

ADT simply offers a superior product when it comes to equipment build and construction. Xfinity has some catching up to do in this category.

Smart Home Automation 

Xfinity — Xfinity excels in this category. They sell a few smart devices of their own, and they offer smart home integration through a number of third-party platforms. These include Nest, Philips, August & Kwikset smart door locks, etc. Enjoy smart home features that range from remote lighting and thermostat control, to garage door openers, and more.

ADT — ADT offers pretty much everything that Xfinity offers in the smart home automation department. We’re talking smart lights, thermostats, garage door openers, and the list goes on. Unfortunately, ADT is much more expensive across the board.

Smart Home Automation Category Winner: Xfinity

You’ll have to pay for the smart device upgrades, but the low-cost Xfinity system will support total smart home automation for $29.99/mo. for the first year. Compared with ADT’s $48/mo. package, Xfinity is a steal.


Xfinity — Xfinity does not offer do-it-yourself home security systems. You will have to schedule an appointment with a technician for professional installation. It is unclear whether or not Xfinity always charges an installation fee, so be prepared to pay a hefty upfront setup fee.

ADT — Similar to Xfinity, ADT requires professional installation on all of their systems. The good news with professional installation is that you know for certain the system will be installed correctly from the start. The bad news is that you have to bring a stranger into your home and pay them $99-$199 for the installation.

Ease of Installation Category Winner: Tie

Both companies offer (require) professional installation. This is good and bad. We would like to see companies like Xfinity and ADT offer DIY systems. After all, customers like options.

Customer Service

Xfinity — Customer service is not Xfinity’s strong suit. In fact, they were awarded America’s worst company in 2017. To somewhat temper that black eye, Comcast does have a B+ BBB rating. Customers who need help can find it through Xfinity Home’s self-service support portal, live chat, and/or customer service call centers.

ADT — Unlike Xfinity, ADT is known for its reliable service. The company boasts an A+ BBB rating, a full grade higher than Comcast. While ADT’s service isn’t perfect, they are making great strides to level-up their customer service game.

Customer Service Category Winner: ADT

ADT is the clear winner when it comes to customer service. When you sign-up with ADT home security, you’ll most likely enjoy A+ service from a reputable brand.


Xfinity — Xfinity Home security requires a 2-year contract, and their return window is 30-days. But there are no up-front fees to worry about. While long-term contracts aren’t necessarily a deal-breaker, we would like to see a month-to-month option offered by Xfinity and ADT.

ADT — The minimum agreement with ADT is 24 months. The company also offers three-year contracts. Remember though, not all contracts are bad. ADT doesn’t make you pay a steep upfront equipment price. Instead, you’ll pay the equipment rental over time. Also, ADT has the top money-back guarantee in the industry — 6 months! This perk alone makes ADT worth your consideration.

Contracts Category Winner: ADT

The reason ADT takes this category can be summed up in a few words: a 6-month money-back guarantee. Sure, you’re on the line with a minimum 2-year contract, but if the system isn’t working out for you, you can send it back in the first six months and get reimbursed for monitoring expenses. Not bad. There are caveats to this policy, so be sure to read the fine print.

Cost and Value

Xfinity — Xfinity Home offers a long-running deal of just $29.99 per month for the first year. The price then jumps to $39.99/mo. during the second year. Either way, this is a good deal for total home security with 24/7 monitoring and smart home automation. There are no upfront equipment fees, but the installation fees are somewhat a mystery. Some have reported paying sizeable install costs, while others say these costs were waived. Overall, the price is right with Xfinity Home.

ADT — ADT is more expensive than Xfinity, with their monthly monitoring packages ranging from approximately $40-$60 monthly. ADT does offer a landline-based home security system at the $30 price point, but this is strictly for basic bare-bones security. Also, the installation fee ranges from $99 to $199 depending on your system and setup requirements. Although you can expect to pay more for ADT, you’re getting top-of-the-line home security and automation from a highly reputable company that’s been in the home security game for 150 years. In other words, you get what you pay for.

Cost and Value Category Winner: ADT

Both companies deliver a premium home security experience. But ADT is the better overall value. ADT offers a range of security systems and monitoring options, superior hardware, and they have A+ service to keep customers happy. Now, if Xfinity stayed at $29.99/mo. throughout the life of the service, it might be a different story. But in the end, ADT wins for cost and value.

Xfinity and ADT are two popular home security options. They each deliver where it matters most — features and tech, home automation, and of course, reliable home security. But like always, there can only be one winner. See below for our at-a-glance breakdown of the category winners.

  • Age and Influence: Winner – ADT
  • Features and Technology: Winner – Tie
  • Monitoring Options: Winner – ADT
  • Emergency Connections: Winner – ADT

As much as we want to cover everything about Xfinity and ADT, time doesn't permit us. So instead, we answered some of the most frequently asked questions about the two alarm companies here.

  • Which is better, Xfinity or ADT home security?

    ADT is better than Xfinity overall in terms of reputation, monitoring options, emergency response, equipment quality, customer service, contracts, and value. However, choosing a security system is a personal choice, so you have to consider your situation. If you want a superior security system, ADT is the way to go. If you are already a Comcast customer and want to save money, you can bundle Xfinity home security with other Comcast services.

  • How much does Xfinity and ADT cost?

    Xfinity and ADT both cost $30 to $60 per month. Xfinity starts at $29.99 per month for the first year, but that price will jump up to $39.99 per month in the second year. The price jump is due to Xfinity’s introductory price promo that gives customers a lower first-year price than the regular price. On the other hand, ADT costs $40 to $60 per month depending on the features and the equipment. ADT’s cheapest monitoring plan includes intrusion monitoring and not much else. If you choose a more expensive plan, you can get additional features such as home automation and video monitoring.

    Xfinity ADT
    Monthly monitoring rate $29.99-$39.99 $40-$60
    Contract length 2 years 3 years
    Money-back guarantee 30 days 6 months
  • Do Xfinity and ADT call the police in case of emergencies?

    Xfinity and ADT call the police in case of emergencies, also known as professional monitoring. Xfinity and ADT systems are linked to their respective monitoring centers, and when there’s an alarm, the system will call the monitoring center. There, an agent will assess the situation and call the police if needed.

  • Do Xfinity and ADT systems work without a monitoring service?

    Xfinity and ADT systems don’t work without a monitoring service. You might still get local alarms during emergencies through the systems’ sirens, but they won’t send you text, email, or app alerts and they won’t call the police. While sirens might be able to repel would-be thieves, we recommend having a 24/7 professional monitoring service to go with your security system.
