The Honest Answer
Xfinity Home's professionally monitored plans include cellular backup, so the system itself keeps working if you cancel Xfinity internet or lose your connection. What changes is cost: Xfinity has offered a discount for bundling Home with internet, so dropping internet service can raise your monthly bill even though the alarm still functions. Separately, most customers finance the equipment on a payment plan (commonly around 24 months), and cancelling early typically means paying off that remaining balance, regardless of your internet status. ADT-powered systems through an authorized dealer are not tied to any internet or cable subscription at all.
NetSecure360 is an authorized ADT dealer headquartered in Camp Hill, PA, serving homeowners nationwide. Xfinity Home is a service of Comcast, a separate company. We reference Xfinity Home here for an honest, sourced comparison only; Xfinity is a trademark of its respective owner.

The Internet Question, Answered Precisely
This is the detail most comparison pages get vague about. Xfinity Home's professionally monitored plans include cellular backup as part of the service, so a cut cable line, a power outage, or cancelling Xfinity internet entirely does not turn the alarm system off. You also do not need to be an Xfinity internet subscriber to sign up for Xfinity Home in the first place. The part that does change is your bill: Xfinity has offered a discount for bundling Home monitoring with internet service, so dropping internet can mean paying more for the same monitoring, not losing protection outright. If cost, not function, is your concern, that distinction matters.
Want monitoring that is not tied to a cable bill?
An ADT-powered system through NetSecure360 is not bundled with any internet or cable subscription, so there is nothing to unwind if you change providers.

Xfinity markets its Home plans as not requiring a traditional service contract, which is accurate as far as it goes. What that framing leaves out is that most customers finance the equipment separately on a payment plan commonly reported around 24 months. Cancel before that plan is paid off, and you typically owe the remaining equipment balance, which functions a lot like an early termination fee even though it is not labeled one. ADT-powered monitoring agreements through NetSecure360 disclose the actual commitment length upfront rather than splitting it across a separate equipment financing structure. Either way, ask exactly what you would owe if you cancelled tomorrow, in writing, before you sign.
Which Actually Fits Your Situation
If you already have Xfinity internet, plan to keep it long-term, and like the convenience of one bill, Xfinity Home's bundle can make practical sense. If you might switch internet providers, want hardware that is not locked to one company's app, or simply do not want a security decision tangled up with a cable subscription, an ADT-powered system through an authorized dealer keeps those two decisions separate on purpose.
Frequently Asked Questions
Does Xfinity Home work if I cancel Xfinity internet?
Functionally, yes. Xfinity Home's professionally monitored plans include cellular backup, which keeps the system connected even without Xfinity internet or during an outage. You also do not need to be a Comcast internet customer to sign up for Xfinity Home in the first place. What changes if you cancel Xfinity internet is cost, not function: Xfinity has offered a bundle discount for having both services, so dropping internet can raise your monitoring bill even though the security system itself keeps working.
Is Xfinity Home a contract or no contract?
Xfinity has marketed its Home plans as not requiring a service contract, but most customers finance the equipment on a separate payment plan, commonly reported around 24 months. If you cancel before that plan is paid off, you typically owe the remaining equipment balance. In practice this functions similarly to a contract, it is just structured as equipment financing rather than a monitoring-service commitment.
How much does Xfinity Home monitoring cost?
Third-party reporting from Security.org describes a self-monitoring option at a lower monthly cost and a professionally monitored 24/7 plan at a higher monthly cost, with an additional monthly charge while an equipment payment plan is active. Xfinity has also offered a bundle discount when paired with Xfinity internet. Confirm current pricing directly with Xfinity, since promotional terms change.
Can I use Xfinity Home equipment with a different monitoring company?
Generally no. Xfinity Home uses its own proprietary hub and app, similar to how most all-in-one providers lock hardware to their own monitoring service. If you switch providers, Xfinity Home equipment typically does not transfer, which is worth weighing against an ADT-powered system that integrates open Google Nest hardware you could theoretically use with other services later.
