Direct answer: Which home security systems have the most lock-in risk?
ADT's professionally installed plans carry the highest lock-in risk in 2026 — a mandatory 36-month monitoring contract with an early termination fee of approximately 75% of the remaining balance. Vivint is the second-highest risk: while Vivint has no monitoring contract, most buyers finance equipment over 42–60 months, creating a functional multi-year commitment even without a signed service agreement. Every other major brand — SimpliSafe, Ring, Cove, Eufy, Abode, Arlo, and Wyze — operates month-to-month with no early termination fee on either monitoring or equipment.
What this report measures

Six things every home security buyer should understand before signing anything.
The Contract Risk Index (CRI) is a SecurityCompassHQ editorial framework for evaluating financial lock-in risk across home security brands. It uses a 1–5 scale based on four factors: monitoring contract length, equipment commitment structure, equipment portability, and early termination fee exposure. Scores are derived from publicly available contract terms, pricing pages, and financing disclosures — not from advertising relationships or brand-provided summaries.
SecurityCompassHQ Contract Risk Index — Scale
1 — Lowest risk
Month-to-month monitoring, equipment purchased outright, fully portable, no ETF.
2 — Low risk
Month-to-month monitoring, equipment outright or short financing, portable with minor effort.
3 — Moderate risk
Either monitoring OR equipment creates commitment, but not both. Commitment under 24 months.
4 — High risk
Multi-year equipment financing OR long monitoring contract. Pro-installed equipment, limited portability.
5 — Highest risk
Multi-year monitoring contract AND long financing OR pro installation creating a functionally permanent setup.

View pricing guide →The most common buyer mistake in the home security category is treating "no monitoring contract" as equivalent to "no financial commitment." These are not the same thing — and the distinction is most consequential when evaluating Vivint.
A monitoring contract is an agreement to pay for alarm dispatch service for a fixed term. Equipment financing is a separate loan for the physical hardware. Canceling monitoring does not cancel your equipment financing obligation. Vivint's monitoring is genuinely month-to-month — you can cancel it at any time with no penalty. But if you financed $1,200 in equipment over 60 months, those payments continue whether or not your system is actively monitored.
This is why Vivint earns a CRI score of 4 rather than 1. The equipment financing term — typically 42 to 60 months — is the actual commitment most Vivint buyers are entering. The "no contract" framing is accurate for monitoring; it does not describe the full financial picture for buyers who finance equipment.
Equipment financing at Vivint typically runs through a third-party lender. The financing agreement is separate from the monitoring service agreement. The practical consequences:
The one exception: buyers who purchase Vivint equipment outright — paying the full $599–$1,500+ at purchase rather than financing — have no multi-year financial obligation. Monitoring is month-to-month and cancellable at any time. For buyers with the capital to pay upfront, Vivint's CRI is effectively closer to 2.
ADT is unusual in that it has two meaningfully different contract structures under the same brand. The professionally installed path requires a 36-month monitoring contract with a ~75% ETF. The DIY Self Setup path (launched as a more prominent offering in 2025–2026) is month-to-month at $24.99/month with no contract and no ETF. These are not equivalent products — they have different installation methods, different monitoring configurations, and different pricing — but both carry the ADT name. Buyers researching ADT need to identify which path they are considering before evaluating their risk.

The following analysis covers each brand's specific contract structure, what the "no contract" claim means in practice where applicable, and what to verify before signing. Scores are from the SecurityCompassHQ Contract Risk Index as of April 2026.
Score rationale: Vivint earns a CRI of 4 because equipment financing — which the majority of buyers use — creates a 42–60 month obligation that continues independently of monitoring. Professional installation makes equipment difficult to relocate. Monitoring itself is genuinely month-to-month with no ETF.
What "no contract" means in practice: Vivint's monitoring service is month-to-month. You can cancel professional monitoring at any time with no early termination fee on the service itself. The commitment most buyers underestimate is the equipment financing: 42–60 months through a third-party lender. Those payments continue regardless of monitoring status. The system is professionally installed and not designed for self-relocation.
What to verify before signing: Ask Vivint specifically: (1) what is the total equipment purchase price if paying upfront, (2) what is the full financing term in months and total amount financed, (3) what is the monthly equipment payment separate from monitoring, and (4) what happens to the equipment obligation if you move before the financing term ends.
Easiest exit path: Pay for equipment upfront — this eliminates the financing obligation entirely. Monitoring is then fully month-to-month. Budget for $599–$1,500+ depending on the package.
Score rationale: ADT's professionally installed plan earns CRI 5 — the highest possible — because it combines a 36-month monitoring contract with professionally installed proprietary equipment and a substantial ETF. ADT's DIY Self Setup earns CRI 2: monitoring is month-to-month at $24.99/month, no contract, and equipment is DIY-installed, though still ADT-proprietary.
The ETF in concrete terms: ADT's early termination clause typically requires paying approximately 75% of the remaining monitoring contract value. If you sign a 24-month plan at $52.99/month and need to cancel after 12 months, you owe approximately 75% × 12 months × $52.99 = roughly $477. The exact amount depends on your specific contract — always confirm the ETF formula before signing.
The two-path distinction: ADT's DIY Self Setup is a genuinely different product — month-to-month, no ETF, self-installed — despite carrying the same ADT brand. If you are considering ADT, clarify at the outset which path you are evaluating. The contract risk exposure differs substantially between them.
What to verify before signing: (1) Confirm whether you are signing a 2-year or 3-year contract. (2) Ask for the exact ETF formula in writing. (3) Confirm what "6-month money-back guarantee" covers — ADT advertises this, but understand the scope. (4) If you are a renter or expect to move, the ETF risk is disproportionate — consider ADT's DIY path or a different brand entirely.
Score rationale: SimpliSafe earns CRI 1 across all plan tiers — including its $79.99/month Pro Plus plan. There is no monitoring contract at any level. Equipment is purchased outright with a 60-day money-back guarantee. All sensors use adhesive mounts and are wireless — the system can be fully removed and reinstalled in a new home without tools.
What "no contract" means in practice: Genuinely month-to-month at every tier. You can cancel, downgrade, or pause monitoring at any time with no fee. Professional monitoring starts at $22.99/month — the $9.99/month tier is self-monitoring only (app alerts, no dispatch). Either way, no contract.
Best for: Renters who move frequently, buyers who want professional monitoring quality without any long-term commitment, and households where budget flexibility matters.
Score rationale: Ring Alarm earns CRI 1. Monitoring is month-to-month with no contract. Following Ring's January 2026 plan restructure, professional 24/7 monitoring requires the AI Pro plan at $19.99/month. Equipment is purchased outright, DIY-installed, and portable. No ETF on monitoring or equipment.
Notable context: Ring's camera and doorbell ecosystem is strong — if you are already in the Amazon/Alexa ecosystem, Ring Alarm integrates seamlessly. The alarm system's low lock-in profile is a genuine advantage for buyers who want flexibility.
Cove, Eufy, Abode, Arlo, Wyze — all CRI 1
All five brands earn the lowest possible Contract Risk Index score. Each is month-to-month on monitoring, sells equipment outright without financing obligations, and installs via DIY with wireless sensors. None has an early termination fee. Key distinctions within this group:
Ranked from easiest to exit to hardest to unwind, based on SecurityCompassHQ Contract Risk Index scores and specific exit-cost analysis as of April 2026.
Easiest to exit — CRI 1
SimpliSafe, Ring, Cove, Eufy, Abode, Arlo, Wyze
Cancel monitoring at any time, no fee. Equipment purchased outright. Wireless, portable sensors. Some offer 60-day money-back on equipment.
Low exit friction — CRI 2
ADT DIY Self Setup
Month-to-month at $24.99/mo, no contract, no ETF. Equipment is DIY-installed but ADT-proprietary — less portable than pure DIY brands.
High commitment — CRI 4
Vivint (financed equipment)
Monitoring cancellable anytime. But 42–60 month equipment financing continues. Pro-installed equipment not DIY-portable. Paying upfront drops risk substantially.
Hardest to unwind — CRI 5
ADT Professional Install
36-month monitoring contract. ETF ~75% of remaining balance. Pro-installed proprietary equipment. Both monitoring AND equipment create simultaneous obligations.

Limitations
Which home security system has the most lock-in risk?
ADT's professionally installed plans carry the highest lock-in risk — a mandatory 36-month monitoring contract with an early termination fee of approximately 75% of the remaining balance. Vivint is second due to 42–60 month equipment financing that continues even after monitoring is canceled. Every other major brand analyzed is month-to-month with no ETF.
What is the difference between a monitoring contract and equipment financing?
A monitoring contract obligates you to pay for professional alarm-dispatch service for a fixed term. Equipment financing is a separate loan for the physical hardware. They are legally distinct obligations — canceling one does not cancel the other. At Vivint, for example, you can cancel monitoring anytime with no fee, but your equipment loan payments continue for the full financing term regardless of monitoring status.
Which home security system is easiest to cancel?
SimpliSafe, Ring Alarm, Cove, Eufy, Abode, Arlo, and Wyze are all month-to-month with no early termination fee on monitoring or equipment. SimpliSafe and Cove also offer 60-day money-back guarantees on equipment. You can cancel any of these services at any time with no financial penalty — making them the lowest-friction exit options in the category.
Can I get out of a Vivint agreement?
You can cancel Vivint monitoring at any time with no early termination fee on the service side — Vivint's monitoring is month-to-month. However, if you financed the equipment, you remain responsible for all remaining equipment payments regardless of monitoring status. The equipment financing (typically 42–60 months) is a separate obligation from the monitoring service. Paying off your equipment balance in full ends the financing obligation.
Does ADT have an early termination fee?
Yes — on its professionally installed plans. ADT typically requires a 36-month monitoring contract, and the ETF is approximately 75% of the remaining contract value. For example, canceling 12 months into a 24-month plan at $52.99/month could cost approximately $477. ADT's DIY Self Setup path has no contract and no ETF — it's month-to-month at $24.99/month. Always confirm the exact ETF formula in your specific contract before signing.
Is SimpliSafe really contract-free?
Yes. SimpliSafe has no monitoring contract at any plan tier — including its $79.99/month Pro Plus plan. You can cancel or downgrade at any time. Equipment is purchased outright with a 60-day money-back guarantee. There is no ETF and no financing obligation. SimpliSafe earns a Contract Risk Index score of 1 (lowest risk) in SecurityCompassHQ's 2026 analysis — the same score as Ring, Cove, Eufy, Abode, Arlo, and Wyze.
Does Vivint require a contract?
Vivint does not require a monitoring contract — monitoring is month-to-month and can be canceled at any time with no fee. The nuance is equipment financing. Most buyers finance Vivint's equipment over 42–60 months through a third-party lender. Those payments continue independently of monitoring status. If you purchase equipment upfront — paying the full $599–$1,500+ at the time of installation — there is no multi-year financial obligation on either monitoring or equipment.
