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

PathTypical upfront (July 2026)Notes
DIY starter kit (apartment / small home)~$160–$300Ring'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–$700SimpliSafe 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 financedEquipment 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 communicatorOften 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–$33/month. Wyze and eufy around $9.99; Ring around $19.99–$20; Cove from $19.99–$22.99; SimpliSafe $22.99 (Standard) to $32.99 (Core); Abode around $26.99.
  • Takeover monitoring of an existing wired system: from roughly $8–$10/month (GeoArm, Alarm Grid).
  • Traditional contract providers: ADT Self Setup from around $34.99/month; ADT professionally installed plans around $49.99–$54/month; Brinks roughly $39.99–$49.99/month; Vivint monitoring around $39.99–$49.99/month plus any equipment loan payment.

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 typeTypical term (July 2026)Early exit
DIY brands (SimpliSafe, Ring, Abode, Cove, Wyze, eufy)Month-to-monthCancel anytime; you own the equipment
ADT (professional install)36 months in most states; 24 in CaliforniaETF up to 75% of remaining monthly charges
Brinks36 months reportedETF reported at a large share of the remaining balance (figures around 80% appear in third-party guides - confirm your own contract, as we could not verify this in Brinks' current published terms)
VivintMonth-to-month monitoring if equipment is paid upfront; otherwise tied to a 42- or 60-month equipment loanCancelling 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, by the way, usually does not void the contract - providers typically offer to move service with you instead.

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.

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 at around $39.99–$49.99/month. 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?"

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

ProviderHow you cancel (as published/reported, July 2026)Friction level
SimpliSafe, Ring, Abode, Wyze, eufy, CoveCancel subscription by phone/account settings; no penalty; keep equipmentLow - though some brands require a phone call and identity verification, and retention offers are common
ADTPhone call required; retention pitch; ETF if in-term; written confirmation advisableHigh in-term, moderate after term - third-party guides consistently describe multi-step retention flows
VivintNotice requirements plus payoff of any equipment balanceHigh if financed; low only if equipment was paid upfront
BrinksPhone-based cancellation with notice period; complaints about the process are common on consumer boardsHigh 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

  1. What is the total of all payments - equipment, monitoring, fees - over the full term?
  2. Is the equipment purchased, financed, or leased? Who owns it on day one, and at the end?
  3. If I cancel after 12 months, what exactly do I owe? (Make them show the ETF formula.)
  4. Can you raise my rate during the term? If you do, can I exit without penalty?
  5. What happens at the end of the term - auto-renewal length, notice window, and how notice must be delivered?
  6. If I move, what are my options and costs?
  7. If I later switch providers, can another company monitor this equipment, or is the panel proprietary?
  8. What's the trial/money-back window, and does it cover installation fees?
  9. 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.)
  10. Which of these answers are in the written contract, and where? (If an answer exists only verbally, it doesn't exist.)
