9 Security System Contract Terms Wisconsinites Can’t Get Out Of

A home security contract can lock a customer in for years.

Getting back out often isn’t cheap.

These are the security system contract terms Wisconsinites can’t get out of.

Note: This is general information, not legal or financial advice. Contract terms, fees, and cancellation rules are subject to change.

1. Three-Year Minimum

ADT, one of the country’s largest home security companies, runs a standard residential contract for 36 months, and Wisconsin doesn’t get a shorter version.

Only California customers get the 24-month term ADT lists for that state.

Vivint runs longer.

A financed system there can stretch the contract to 60 months.

Vivint ties the length of that service agreement directly to how many months a customer takes to pay off the equipment.

Neither term bends for a change of mind.

A customer who wants out early needs a reason the contract itself recognizes, and changing your mind isn’t one of them.

2. Early-Exit Math

ADT’s contract lets the company charge 75% of the monitoring payments still owed on the initial term if a customer cancels early.

That’s a lot of money.

On a $50-a-month plan with 20 months left on a 36-month term, that penalty runs about $750, due all at once instead of spread out over nearly two more years.

Vivint and many national providers use some version of a remaining-balance formula for early termination, even when the exact percentage differs by company.

The number only shrinks as the original term winds down, and it resets the moment a contract renews into a fresh term.

3. Equipment You’re Still Financing

Vivint ties its home security equipment to a separate financing contract, and that contract survives even after a customer cancels monitoring.

The bill doesn’t stop.

A customer can pay off the remaining balance in full at any time with no penalty, according to Vivint’s financing terms.

Returning the hardware works too, but only inside the three-business-day window the law allows for a sale made in the home.

Equipment financed this way typically runs $299 to $1,499 or more, spread across as many as 60 monthly payments.

The unpaid balance comes due either way.

4. Auto-Renewing Contracts

Some security companies renew a customer’s contract automatically into a brand-new term, not a simple month-to-month extension.

Connecticut-based Safe Home Security did exactly that for years, rolling customers into another full year of payments unless they caught the renewal date and canceled in writing first.

Many customers never caught it.

Massachusetts’s attorney general made the company change course in 2023, requiring a $6.5 million payout and a switch to month-to-month renewals going forward.

Anyone signing with a provider that still runs the old way stays on the hook for another full term unless the cancellation window gets caught days in advance.

5. Rate Hike You Miss

ADT’s contract gives the company the right to raise the monthly monitoring price at any time after a customer’s first year.

There’s no separate warning.

If a customer misses the 30-day window to file a written objection, the higher price becomes the price for whatever’s left of the original term.

A written objection inside that window is the only way to fight it, and even a successful one only buys a penalty-free cancellation a month later, not a lower bill.

6. Relocation Catch

Vivint doesn’t treat a household move as a reason to cancel its security contract.

The company asks a customer to call at least two weeks before moving day.

From there, it offers to uninstall the system, reinstall it at the new address, or leave the equipment behind for the next owner.

That’s logistics, not an exit.

ADT’s contract literature and independent reviews describe a similar pattern.

A mover typically gets the old contract closed only by opening a brand-new contract, on the same multi-year terms, at the new house.

A clean, penalty-free walkaway isn’t on the menu either way.

7. Your Contract, Resold

A signed security contract doesn’t always stay with the company a customer signed it with.

Nobody signs off on the sale.

It happens at scale.

One dealer, Pinnacle Security, sold 93,000 customer contracts to Monitronics in a single deal.

Every one of those households kept the same monitoring bill and the same remaining term, just under a different company’s name.

8. Security Contracts After Death

A security contract doesn’t end automatically when the person who signed it dies.

A Utah television station investigated one case where a company refused to close a deceased customer’s account.

The company told the family the contract ran through 2018, with payments still due.

The family had to produce a death certificate.

That wasn’t enough.

The company then asked for a second document: A written statement confirming the estate had no money left, before it would finally cancel the account for good.

9. Wisconsin’s Three-Day Window

If a buyer misses the three-day window to cancel, the multi-year term already signed is the one that stands.

State law gives a buyer three business days to cancel a contract signed away from the seller’s regular place of business.

It closes fast.

That covers a door-to-door pitch or a sales call the company placed to a home, not a system ordered online or by phone.

A matching three-business-day window backs it up nationwide under federal law.
