Security System Costs, Contracts, and Cancellation: The Fine Print
Some links to providers on this page may become affiliate links in the future, which could earn us a commission at no cost to you. As of July 2026 we have no active affiliate partnerships. Read our full disclosure.
Judge a system by its total cost over the full term, not the advertised monthly price. A DIY setup runs roughly $200–$700 upfront plus $0–$35 a month; a traditional professionally installed contract is little upfront but commonly $40–$60+ a month across 3 to 5 years, a five-year gap that can top $2,000. Watch for auto-renewal clauses, mid-contract rate increases, and "no contract" that is really multi-year equipment financing.
Home security pricing is engineered to make the first number you see small and the last number you pay large. "Free installation" recovers its cost in the monthly rate. "$0 down" means a five-year equipment loan. "No contract" sometimes means the monitoring has no contract while the equipment financing very much does. This page collects the fine print - cost ranges verified as of July 2026, contract mechanics, termination math, and the questions that surface all of it before you sign.
All prices below are around the listed amounts as of July 2026 - verify current pricing directly with providers, because promotions in this industry change weekly.
Upfront costs: what equipment really runs
| Path | Typical upfront (July 2026) | Notes |
|---|---|---|
| DIY starter kit (apartment / small home) | ~$160–$300 | Ring's 8-piece Alarm kit listed around $250–$305; Wyze's core kit around $112 plus hub; SimpliSafe packages started around $250 |
| DIY kit, typical 3-bed house | ~$300–$700 | SimpliSafe packages ran roughly $250–$730 at list; steep discounts (30–70%) are near-constant at Cove and common elsewhere |
| Pro-installed system (ADT, Vivint) | $0 down to $600+, or financed | Equipment packages often reach $600 to several thousand dollars, spread across financing (see below); install/activation fees vary by promotion |
| Reusing an existing wired system | ~$0–$200 for a communicator | Often the cheapest path of all - see using old ADT equipment and what to do with an inherited alarm |
Two pricing behaviors to know. First, list prices in this category are soft: Cove, for example, was advertising 70% off most equipment in mid-2026, and Black Friday/Prime Day discounts on DIY kits are dependable. Never pay list without checking. Second, "free equipment" from contract providers isn't free - it's amortized into 36–60 months of elevated monthly payments. Always compare total cost over the full term.
Monthly costs
- Self-monitoring: $0 on most DIY brands (Ring, Abode, eufy, Wyze); camera cloud storage typically $3–$10/month if you want it. SimpliSafe's camera self-monitoring plan was $9.99/month.
- No-contract professional monitoring: roughly $10–$43/month. Wyze and eufy around $9.99; Ring around $19.99–$20; Cove $22.99 (Basic) to $42.99 (Premium); SimpliSafe $22.99 (Standard) to $32.99 (Core); Abode around $26.99. One thing worth knowing before you compare any of these: as of our August 7, 2026 check, neither Cove nor SimpliSafe publishes a monthly price on its own plan page at all. Both quote a daily rate. Cove lists $0.77, $1.10 and $1.43 a day; SimpliSafe lists 76¢ a day for Standard, $1.10 for Core, $1.66 to $2.66 for Pro and Pro Plus, and 33¢ for self-monitoring with camera recordings. The monthly figures we show above are those daily rates multiplied by 30. We do not know when either company adopted the daily format, so treat this as a description of what those pages say today rather than as a recent change. The point is simply that 76¢ a day and $22.99 a month are the same number, one of them is harder to add up over a year, and it is the one you see first.
- Takeover monitoring of an existing wired system: from roughly $8–$10/month (GeoArm, Alarm Grid).
- Traditional contract providers: ADT Self Setup professional monitoring from $24.99 to $37.99/month depending on the kit, month-to-month and requiring AutoPay enrolment (ADT's own shop terms, verified 2026-08-09); ADT professionally installed plans from $59.99/month, which is a floor rather than a range: as of 2026-08-09 that figure appears only in the fine print of ADT's current promotion ("36 mo. pro monitoring plan starting at $59.99/mo"), and ADT publishes no monthly price at all on its main security page, its package comparison page or its DIY comparison page, while adt.com/pricing returns a "not found" page. The $45.99 figure this page carried until today no longer appears anywhere on ADT's site; Brinks Home publishes "Protection starts at just $29.99/month" alongside free professional installation on its own how-to-buy page (read 2026-08-20), and states no contract term there; this page previously said "roughly $39.99–$49.99/month" with no source, which overstated Brinks' published floor by $10 (see the correction note below); Vivint publishes only "Vivint Monitoring starts at $24.99/mo" (verified on Vivint's own page 2026-08-06), and that starting figure is before cameras, before add-on devices and before the equipment loan payment, which is why real Vivint bills land far above it. Correction, August 17, 2026: this page previously said Vivint no longer publishes a package price list at all. That was wrong, and it was wrong because we had only been reading Vivint's buying page. Vivint's own pricing article does publish a package list, including upfront equipment prices, 0% APR monthly equivalents and approximate monitoring for each package, and it publishes both installation prices for its HomeProtect package. The accurate version is narrower: Vivint's buying page routes you to a phone call, while the figures live in an article you have to already be looking for. See our audit of published installation and setup fees for what those two paths cost side by side.
The 5-year math makes the stakes clear: $9.99/month is about $600 over five years; $49.99/month is about $3,000 - before equipment. Which level of service you actually need is the subject of our monitoring decision guide.
Contract lengths and what they really mean
| Provider type | Typical term (July 2026) | Early exit |
|---|---|---|
| DIY brands (SimpliSafe, Ring, Abode, Cove, Wyze, eufy) | Month-to-month | Cancel anytime; you own the equipment |
| ADT (professional install) | 36 months, and 24 months in California. Both figures are ADT's own, from the offer terms on its legal pages | "75% of the total remaining monthly charges", stated in capitals in Paragraph 2 of ADT's published Monitoring Contract Terms. No termination charge is due if you cancel during a 30-day renewal period |
| Brinks | 36 months reported | ETF reported around 80% of the remaining balance (third-party figure - confirm against your own contract) |
| Vivint | Month-to-month monitoring if equipment is paid upfront; otherwise tied to an equipment loan reported at 42 or 60 months. Vivint publishes no term on its own site, so the 42-to-60 range is a third-party figure | Cancelling generally requires paying off the equipment balance |
Read the term as a debt: a 36-month contract at $50/month is a $1,800 commitment, and the ETF clause determines how much of it you owe if life changes. Moving is the exception people are most often told wrongly about. ADT's own support site says that a move requires cancelling "in most cases", because monitoring contracts are "typically tied to the location of the home being monitored", and its residential terms state that a professionally installed system remains ADT's property. Whether your provider will transfer the term, restart it, or end it is a question to settle in writing before you list the house; our guide to moving with a security system sets out what each of six providers publishes.
Which companies will tell you the terms before you call
We re-read providers' own pages on a rolling schedule. On August 16, 2026 we read five of them for contract language rather than for price, and the interesting difference was not the length of the term. It was whether a shopper can find the term at all without first handing a salesperson a phone number.
| Provider | Is the term published on its own site? | Is the early-exit fee published? | Where you find it |
|---|---|---|---|
| Frontpoint | Yes. 36 months, stated for all three monitoring plans | Yes, with the formula: "an early termination fee of 80% of the monthly charges for the remainder of the contract term" | A standing Offer Details page linked from the site footer |
| ADT (professionally installed) | Yes. "36 mo. pro monitoring plan starting at $59.99/mo" | Yes, and this row was corrected on August 19, 2026. The deals-page fine print says only "Early term fees", but the "terms here" link on that same fine print leads to a page that quantifies it: "ADT may charge 75% of the monthly service charges due for the balance of the initial contract term". The full clause is in ADT's Monitoring Contract Terms, Paragraph 2 | Promotional fine print on the deals page, one click from the quantified figure |
| ADT Blu (self setup) | Yes. "no long-term contracts" | Not applicable | The same deals page |
| Cove | Yes. "No Contracts, Cancel Anytime", listed as a feature on every tier | Not applicable | On the monitoring plan page itself |
| SimpliSafe | Not on its monitoring plan page, which carries per-day prices and a feature grid and no term at all | Not applicable | Not on that page |
| Vivint | No. Vivint publishes two figures, "Equipment starts at $199.99" and "Vivint Monitoring starts at $24.99/mo", and routes everything else to a phone call (read 2026-08-15) | No | Not published |
Correction, August 20, 2026. The monitoring list above described Brinks Home as "roughly $39.99 to $49.99 a month". That figure carried no source, and it was found by a sweep of this site's own unsourced price claims rather than by a reader. Brinks Home's own how-to-buy page, read on August 20, 2026, states "Protection starts at just $29.99/month". Our figure was $10 above what the company publishes, which is the kind of error that makes a provider look more expensive than it says it is, so the correction is stated here rather than made quietly. A caveat that applies to every starting rate on this page, including this one: a published floor is the price of the smallest system a company sells, and Vivint is the only large provider we have found that also publishes what monitoring costs on its standard packages, where it runs approximately $47 to $57 a month against a $24.99 floor.
Correction, August 19, 2026. When this table was first published on August 16 it recorded ADT's early-exit fee as named but not quantified. That understated what ADT publishes. Re-reading the same fine print on August 19 and following its own "terms here" link reaches a page that states the figure outright, and ADT's full Monitoring Contract Terms state it in capitals. ADT publishes its early-termination percentage; it simply takes one more click than Frontpoint's does. The row has been corrected. We would rather record that we were unfair to a company than leave it standing.
Read that table for its shape rather than for a winner. The provider stating the harshest exit terms here, Frontpoint at 80%, is also the one stating them plainly on a page anyone can open without talking to a human being, and ADT's 75% is one link away from its own promotional fine print. The provider publishing the least, Vivint, is not offering a shorter commitment in exchange; it is offering the same kind of commitment with the paperwork arriving later, once someone is already in your living room. "We will build you a custom quote" is a pricing strategy, not a courtesy.
A practical use for this: before any sales conversation, open the provider's own terms page and save the term length and the exit clause. If you cannot find either one, that is your first question, and the answer belongs in writing rather than in a conversation.
Is a five-year contract normal?
No, and the confusion is usually two separate documents being described as one. The longest monitoring term any provider above publishes is 36 months. Where five years turns up is the equipment rather than the monitoring: financed hardware has been documented at 42 to 60 months, and that loan is a separate agreement with its own balance, which does not end when the monitoring service does. Vivint no longer publishes those financing terms on its own site at all, which is a large part of why the number reaches people as a rumour instead of as a clause.
So when a quote mentions five years, the useful question is not whether that is normal. It is which of the two agreements the number belongs to, and what happens to the other one if you cancel. Our guide to what no money down home security actually costs works through a real offer where those two numbers come apart.
The clauses that bite
Auto-renewal
Many traditional contracts renew automatically at the end of the initial term - sometimes month-to-month, sometimes for a further fixed period depending on the agreement and state law (a number of states restrict long auto-renewals). The practical trap: cancellation usually requires notice within a specific window, in writing, and sometimes only after speaking to a retention department. Calendar your contract end date the day you sign, and ask exactly what the renewal term and notice window are.
Mid-contract price increases
ADT's published residential terms, for example, allow it to increase the service charge after the first year of the term. The offsetting consumer right in those terms: if you object in writing within 30 days of the increase notice and ADT doesn't waive the increase, you can terminate without the termination charge. Most customers never learn this. Whoever your provider is, find the rate-increase clause before signing and ask whether an increase gives you a penalty-free exit - then keep every increase notice you receive.
Early termination fees
Worked example using ADT's published structure (up to 75% of remaining monthly charges): cancel a $50/month, 36-month contract at month 12 and you can owe up to 75% × $50 × 24 remaining months = $900 - to stop receiving a service. This is why the "free" $850 equipment package isn't free. The main penalty-free exits are: the initial trial window (ADT has offered a 6-month money-back guarantee subject to conditions; others offer around 30 days), a qualifying objection to a rate increase (above), and - under the FTC's Cooling-Off Rule - three business days after signing a door-to-door sale. For the full step-by-step, the exact fee math, and every exit that can actually apply to you, see our dedicated guide on how to cancel ADT and when you can avoid the termination fee.
Equipment financing traps
Vivint's Flex Pay model is the clearest example of the modern structure: equipment is bought on a 0%-APR installment loan (42 or 60 months, through a third-party lender, credit check required), and monitoring is billed separately, starting at the $24.99/month Vivint publishes (verified on Vivint's own page 2026-08-06) and rising with cameras and add-on devices. The marketing truthfully says monitoring has no long-term contract - but if you cancel, the equipment loan doesn't cancel with it. You owe the balance on hardware that mostly works only with the provider's service. Before accepting any financed equipment, ask: "If I cancel monitoring after 12 months, exactly what do I owe, and what does the equipment still do?" Already in a Vivint agreement and want out? Our dedicated guide to how to cancel Vivint covers the buyout math, the transfer option, and the documented penalty-free exits.
The same structure is sold under a friendlier name: no money down. Three quite different arrangements share that phrase, and they behave differently the moment you try to leave one. Our guide to what no money down home security actually costs separates the three, works the arithmetic on a real dealer offer and a real early termination fee, and lists the five questions to ask before signing.
Equipment you don't own - or can't reuse
With DIY brands you own everything outright. With traditional providers, read the ownership clause: some equipment is leased, and even owned proprietary panels (like ADT Command) generally can't be taken over by another monitoring company, which quietly eliminates your leverage to switch. Details in our guide to reusing old ADT equipment.
Cancellation difficulty, compared
| Provider | How you cancel (as published/reported, July 2026) | Friction level |
|---|---|---|
| SimpliSafe, Ring, Abode, Wyze, eufy, Cove | Cancel subscription by phone/account settings; no penalty; keep equipment | Low - though some brands require a phone call and identity verification, and retention offers are common |
| ADT | Phone call required; retention pitch; ETF if in-term; written confirmation advisable | High in-term, moderate after term - third-party guides consistently describe multi-step retention flows |
| Vivint | Notice requirements plus payoff of any equipment balance - see our step-by-step guide to cancelling Vivint | High if financed; low only if equipment was paid upfront |
| Brinks | Phone-based cancellation with notice period; complaints about the process are common on consumer boards | High in-term |
General cancellation hygiene regardless of provider: get the cancellation confirmation number and a written/email confirmation, watch the next two billing cycles, and if you're moving, don't rely on the buyer of your home "taking over" the contract unless the provider confirms the transfer in writing.
Questions to ask before signing anything
- What is the total of all payments - equipment, monitoring, fees - over the full term?
- Is the equipment purchased, financed, or leased? Who owns it on day one, and at the end?
- If I cancel after 12 months, what exactly do I owe? (Make them show the ETF formula.)
- Can you raise my rate during the term? If you do, can I exit without penalty?
- What happens at the end of the term - auto-renewal length, notice window, and how notice must be delivered?
- If I move, what are my options and costs?
- If I later switch providers, can another company monitor this equipment, or is the panel proprietary?
- What's the trial/money-back window, and does it cover installation fees?
- Does my city require an alarm permit, and who pays false-alarm fines? (Check yourself here - fines and permit fees are a real recurring cost the sales process never mentions.)
- Which of these answers are in the written contract, and where? (If an answer exists only verbally, it doesn't exist.)
Next step: If the fine print above has soured you on contracts, our no-contract system comparison covers the month-to-month alternatives - and our choosing guide walks the whole decision from the top.
Put your own numbers in: our five-year cost calculator adds up equipment, fees, monitoring, and add-ons for two setups side by side, so you compare the real total instead of the advertised monthly price. For a worked head-to-head, see our ADT vs SimpliSafe true 5-year cost comparison, and for the one-off charges that never appear in a monthly price, our installation and setup fee audit covers which providers publish a figure and which will not.
