ADT vs. Xfinity: What's the difference?
ADT is the hands-off security solution: a certified technician handles setup, 24/7 monitoring runs continuously and Google Nest integration adds smart home capability. With more than 140 years in the industry, ADT carries one of the most recognized names in residential security.
Xfinity Home is Comcast's security and smart home offering, built to work alongside its internet and cable services. It's aimed squarely at existing Comcast customers who want a single monthly bill and a professionally installed system without switching providers.
What we like about ADT
- Service reliability: ADT backs its service with guarantees, including theft protection and a six-month money-back guarantee.
- Smart integration: ADT connects with Google Nest cameras, doorbells and smart locks, enabling features like facial recognition.
What to consider: Committing to a three-year contract is the primary trade-off for ADT's professional service. Equipment costs are also on the higher end, particularly when compared to self-install alternatives.
What we like about Xfinity
- Service integration: Xfinity Home consolidates billing across all Xfinity services, making account management straightforward for existing customers.
- Widespread availability: Because it operates wherever Comcast provides service, Xfinity Home is accessible to millions of households nationwide.
What to consider: Xfinity Home requires bundling with Xfinity Internet, which means non-Comcast customers generally can't access it. You'll also need to keep a minimum internet subscription active to maintain your security service.
ADT vs. Xfinity: System and installation
Both ADT and Xfinity require a professional technician to handle setup. Here's how each company approaches the installation process.

Reputation on ConsumerAffairs
What ADT customers say
ADT holds an overall positive rating on ConsumerAffairs. Many satisfied customers highlight a smooth installation experience, pointing to technicians who walk them through how the system works. Some reviews mention frustration with false alarms and difficulty canceling service. Feedback on customer service was mixed, though a number of customers specifically noted courteous interactions and prompt response times.
“ADT responded real quick when I applied. They were respectful and hooked the system up real quick. They also explained everything. I don't have any difficulty with the system. I just put my code in and if we go up, I just turn it off.”
— Kristy of Amarillo, TX
What Xfinity customers say
Xfinity Home has mixed reviews on ConsumerAffairs. Customers who are happy with the service frequently praise the HD cameras, mobile app control and competitive pricing, describing the overall package as a solid value. Dissatisfied customers tend to focus on customer service frustrations, particularly being transferred between multiple representatives before getting an issue resolved.
“I do like my Xfinity Home security service. I like the keypad by the door and how I can set it when I leave and when I go to bed each night. I'm glad I've never had an intruder but I know if I did I could count on Xfinity Home security service to keep me safe and send the authorities in a hurried manner.”
— Britain of Smyrna, TN
Bottom line: ADT or Xfinity
Choose ADT if you want a hands-off security setup with a long track record and don't mind locking into a multi-year contract. The cost is higher than DIY alternatives, but you're paying for decades of monitoring infrastructure and established service guarantees. If lower costs and flexibility are priorities, a self-install system will serve you better.
Choose Xfinity if you're already a Comcast customer and want the simplicity of a single bill covering internet and home security. It delivers solid smart home features, but the requirement to bundle with Xfinity Internet makes it a non-starter for anyone outside the Comcast ecosystem.
