Cancel a Home Security Contract: ADT, Vivint, SimpliSafe

By Plain Money Guide · Researched from official sources · Editorial standards

Canceling monitoring and clearing the equipment loan are two separate jobs — do both, in writing.

Canceling home security monitoring rarely ends the bill: the monitoring agreement and the equipment loan are two separate contracts, and killing one does not kill the other.

That single fact explains most of the angry reviews you'll find about ADT, Vivint, Brinks and their dealer networks. People call, get told they're canceled, stop paying, and then discover a financed equipment balance still reporting to the credit bureaus months later. Below is what actually differs between the major providers, which situations legitimately get an early-termination fee waived, and how to send notice in a way that holds up.

The two contracts almost nobody separates

When a salesperson sets up a system in your living room, you usually sign a stack that contains at least two distinct agreements:

• The monitoring agreement. This is the recurring service — the central station that calls you and dispatches police. It may run on a fixed term (commonly cited as three years for traditional alarm companies) or month-to-month.
• The equipment agreement. Panels, cameras and sensors are often sold on an installment plan through a third-party lender, or bundled into the monthly total so it looks like one charge. Vivint, for example, has long financed hardware separately from monitoring.

The practical consequence: canceling monitoring can leave you paying for the hardware for years. Before you call anyone, request a full copy of everything you signed — in writing — and read the signature pages. If there are two signature blocks, there are two contracts. If a lender's name you don't recognize appears anywhere, that's your equipment loan.

How the major providers differ

Terms change by year, by state and by whether you bought from a corporate branch or an authorized dealer, so treat this as a map of what to look for rather than a quote. Your own agreement controls.

Provider	Typical structure	What to watch for
ADT	Term monitoring agreement, frequently multi-year	Sold through both company branches and independent authorized dealers; notice sent to the dealer may never reach the monitoring company
Vivint	Month-to-month monitoring with separately financed equipment	The hardware loan can run well past the point you stop monitoring, and it reports as an installment account
Brinks Home	Term monitoring agreements are common	Auto-renewal clause and a written-notice window before the renewal date
SimpliSafe	No long-term monitoring commitment; equipment bought outright	Straightforward to cancel, but prorating and refund handling vary — ask for a final-balance confirmation
Ring Alarm	Month-to-month subscription	Canceling the plan reduces features rather than bricking the hardware
Cable-bundled (Xfinity Home, Cox)	Term or no-term options inside a larger bundle	Unreturned-equipment fees, and losing a bundle discount on the rest of your bill

The single biggest structural difference is dealer versus corporate. Traditional alarm brands sell through networks of independent dealers who install the system and then sell the contract onward to the monitoring company. Your salesperson's phone number is often useless for cancellation. Find the monitoring company's official cancellation address in the contract itself, not on a business card.

When an early-termination fee actually gets waived

Companies rarely waive fees because you changed your mind. They do waive them in specific situations, and these are where the official rules state a principle but real cases split:

The three-day door-to-door window

If the sale happened at your home rather than at a store — which describes a large share of alarm sales — the FTC's Cooling-Off Rule generally gives you three business days to cancel in writing. Read the details on the FTC's cooling-off rule page. Several states extend that window specifically for alarm contracts or for older buyers, so check your state attorney general before assuming you missed it. The catch: the clock runs on the written notice being sent, not received, and a phone call usually doesn't count.

Moving

Most term agreements include a relocation clause, and it almost never means "cancel for free." It typically means you take the service with you and often restart a term. The genuine boundary cases are the ones where you physically cannot: you're moving into a rental where the landlord prohibits installation, into a building with a mandatory building-wide system, or in with family. Providers do sometimes release those contracts, but only with documentation — a lease clause, a letter from the HOA or property manager. Gather the paper before you call.

Death of the subscriber, and military orders

Most agreements release the estate on death of the named subscriber, with a death certificate. For active-duty servicemembers, the Servicemembers Civil Relief Act allows termination of certain service contracts on qualifying orders; whether alarm monitoring falls inside that list can depend on how the contract is written, so ask the provider directly and cite the statute in your written request.

The system doesn't work

Repeated failed signals, sensors that never got fixed, a panel that stopped communicating after a cellular network sunset — a documented service failure is the strongest non-statutory argument you have. It only works if you have a paper trail of service tickets. Start logging every failure and every call before you decide to cancel.

Sending notice so it sticks

1. Request your complete agreement in writing. Ask for the monitoring agreement, any equipment or financing agreement, and the auto-renewal terms. You need the renewal date and the required notice window.
2. Write the notice. Include the account number, the service address, the reason if you're claiming a waiver, and a clear sentence: "I am canceling effective [date] and revoking authorization for further automatic payments."
3. Send it certified mail with return receipt to the cancellation address in the contract — not to the dealer, and not only by email. Send a copy by whatever electronic method they offer as a backstop.
4. Handle the equipment loan separately. Call the lender named on the financing agreement and ask for the payoff amount and whether returning hardware reduces it. Usually it doesn't.
5. Ask for written confirmation of a zero balance and the date monitoring ends. Keep it indefinitely.

Where people follow the rules and still get billed

Four failure patterns account for most of the disputes:

• Notice went to the installer. The dealer who sold you the system no longer holds the contract. Your certified letter sat in an office that has no authority to close the account.
• The call happened, the letter didn't. Nearly every term agreement requires written notice within a specific window before the renewal date. A recorded phone call is not written notice, and the renewal quietly starts a new term.
• Autopay was canceled first. Killing the card or filing a bank stop-payment before the account is closed converts an open dispute into an unpaid debt, and unpaid alarm bills go to collection agencies quickly. If you do revoke payment authorization, do it in writing to the company at the same time, and expect billing to continue until the cancellation is confirmed.
• The house sold and the contract didn't transfer. A buyer verbally agreeing to "take over the alarm" means nothing unless the provider processes an assumption and releases you in writing.

If a balance ends up in collections after you canceled correctly, your certified-mail receipt is the evidence. Dispute it in writing with the collector within 30 days of their first contact — the CFPB's debt collection guide has sample letters — and file a complaint with the CFPB or FTC if it isn't resolved.

FAQ

Does canceling monitoring stop my equipment payments?

Usually no. If the hardware was financed through a lender, that installment loan continues on its own schedule and typically reports to the credit bureaus. Ask the lender for a payoff quote separately from anything the monitoring company tells you.

Can I keep using the system without paying for monitoring?

It depends on the panel. Consumer-brand systems generally keep local siren and app functions when you drop the subscription. Panels installed by traditional alarm companies are often proprietary and may be locked or non-functional without the service — ask before you cancel if self-monitoring is your plan.

Will canceling hurt my credit?

Canceling a service properly does not. What hurts is an unpaid monitoring balance sold to a collection agency, or missed payments on a financed equipment loan. Confirm a zero balance in writing on both before you consider it finished.

Which exit applies to you

The call splits on how you bought and how long ago, not on which brand is on the panel.

• Sold at your home within the last three business days: stop reading and mail written notice. The FTC's Cooling-Off Rule window is the cleanest exit there is, and the clock runs on the notice being sent — so a letter posted today beats a phone call made yesterday, which usually doesn't count at all.
• Past that window, but you have paper: a lease clause barring installation, an HOA or property-manager letter, a death certificate, or qualifying military orders under the SCRA. Argue the waiver in the written notice and cite the basis. The trade-off: moving without that documentation triggers the relocation clause instead, which typically means carrying the service to the new address and often restarting a term — worse than simply serving written notice inside the window before the auto-renewal date.
• No statutory hook, but the system failed: log the tickets first, cancel second. A documented service failure is the strongest non-statutory argument, and worthless without the trail.

In all three cases the equipment loan is a separate job: ask the lender named on the financing agreement for a payoff, since returning hardware usually doesn't reduce it and the account reports to the credit bureaus. And leave autopay running until you hold written confirmation of a zero balance — killing the card first turns a dispute into an unpaid debt, and then you're working the 30-day collector dispute instead.
