What counts as DIY here

A DIY security system in this guide means: you buy the kit outright, you install it yourself with adhesive mounts and an app, and professional monitoring is optional and month-to-month. Every system in this list publishes those terms on its own site. None of the picks below require a technician visit or a multi-year agreement, which is the structural difference from traditional pro-install alarm contracts; the cost gap is quantified in DIY vs professional monitoring cost.

Equipment pricing is promotional and changeable. SimpliSafe's August 2026 sale required signing up for professional monitoring; it runs frequent sales, so check its price on the day you buy. Ring's $199.99 is a markdown from a $244.95 list. Plan against the list prices, treat any promotional price as a snapshot, and treat the monitoring column as the recurring number that actually shapes five-year cost.

Frontpoint is DIY-installed but sold on a contract; Frontpoint cost prices its equipment, monitoring and fees from its own pages. Frontpoint's contract changes the DIY math; is Frontpoint worth it explains when it pays off. Two of the DIY names here go head to head in Frontpoint vs SimpliSafe, which prices the contract and no-contract options side by side.

The picks, scoped to the systems covered here

Best all-around: SimpliSafe. It publishes the widest plan ladder in this list, as of October 2026: from $9.99 a month self-monitoring with camera recordings, through $22.99 a month dispatch-only monitoring (Standard), up to Pro Plus at $79.99 a month, where live agents can deter people outside your home through a Series 2 Outdoor Camera or Video Doorbell (up to 3 in any mix). Its plans page states the same ladder as day rates, 33 cents to $2.66. That ladder means the same hardware can start unmonitored and grow into heavy monitoring without replacement. Sensor specs are solid on paper (entry sensors publish up to 5-year battery life).

Cheapest monitored path: Wyze Home Monitoring at $9.99/month or $99.99/year, with dispatch handled by Noonlight. Wyze also publishes that its leak and climate sensors trigger the same Noonlight text and call. By the published rates in this list, nothing else with 24/7 professional monitoring comes close on price, though the Sense hub, keypad, and sensors are a separate hardware purchase.

Best for camera-heavy homes: Ring Alarm. The $19.99/month Ring Pro plan is the only plan in this table that covers professional monitoring and unlimited-device video recording, cellular backup, and extended warranties in one fee at one address. The 5-piece starter kit at a promotional $199.99 (list $244.95) is also among the cheaper published kits here.

Best smart-home citizen: Abode. Its published integration list (Apple HomeKit, Alexa, Google Home, Home Assistant, Zigbee, Z-Wave, IFTTT, Sonos) is the broadest of the systems covered here, and it works with no subscription at all, with Pro monitoring at $26.99/month when you want it. If you run Home Assistant or a similar hub, Abode is the natural fit in this list.

Best DIY with a big-brand network: ADT Blu, ADT's DIY line, publishing Pro-Protect 24/7 professional monitoring at $24.99 a month ($34.99 with video), month to month with a one-month minimum, as of October 2026. Its cheaper Blu plans, Self-Protect ($14.99) and Video Connect ($9.99, cameras only), send alerts to you only, so Pro-Protect is the plan that puts ADT's monitoring centers behind the system. If you would rather compare professionally installed options, we can fetch real quotes from professional monitoring providers through a short questionnaire.

Budget full-service: Cove, whose Basic plan is published at $22.99/month ($0.77/day), contract-free, with a 60-day full-refund return window. Compare it to SimpliSafe's Standard tier rather than to Core, since neither Cove Basic nor SimpliSafe Standard includes camera access; on that like-for-like basis the published monthly prices are identical, $22.99 each (SimpliSafe Standard as of October 2026), though SimpliSafe's day rate is a cent lower (76 cents against 77).

DIY trade-offs to price in before buying

Self-installation is genuinely easy with these systems (peel-and-stick sensors, app-guided setup), but three trade-offs are worth naming. First, placement quality is on you: a poorly placed motion or entry sensor produces false alarms or coverage gaps, and no installer will catch it. If you have pets, sensor choice matters; see pet-friendly motion sensors. Second, unmonitored or self-monitored modes leave dispatch to you; if an alarm fires while you are unreachable, nobody calls the police. That is the honest cost of the $0/month option, covered in is professional monitoring worth it. Third, promotional equipment discounts are often tied to monitoring sign-up (SimpliSafe's August 2026 60% offer was explicit about this), so the sticker price of a kit is rarely the price you pay without a plan.

For renters, DIY systems are usually the only practical option since everything mounts without drilling; our home security for renters guide covers the landlord-proof details.

Frequently asked questions

What is the best DIY security system?
Of the systems covered here, SimpliSafe is the strongest all-around pick by published plan flexibility (five tiers from $9.99 to $79.99 a month as of October 2026, no contract), Wyze is the cheapest monitored option at $9.99/month, and Ring is the best value for homes with several cameras.
How much does a DIY security system cost?
As of August 2026, the published list prices for starter equipment in this list run from $244.95 for Ring's 5-piece kit to $282.94 for SimpliSafe's smallest package, the 5-piece Break-In Detection kit. A running promotion cut Ring's kit to $199.99, and SimpliSafe runs frequent sales, so check its price on the day. Optional monitoring adds $9.99 to $79.99 per month depending on provider and tier (the top figure is SimpliSafe Pro Plus as of October 2026).
Do DIY security systems require professional monitoring?
No. Every system covered here functions without a subscription in a self-monitored mode. The trade-off is that with no plan there is no professional dispatch, and features like cloud video recording are typically locked behind a plan.
Are DIY systems harder to install than they claim?
The systems covered here use adhesive mounting and app-guided setup, designed for tool-free installation. The real skill is placement: entry sensors on every accessible opening, motion sensors positioned to avoid pet false triggers, and sirens where they can be heard.
Can I get ADT without a contract?
Yes. ADT Blu, ADT's DIY line, is month to month with a one-month minimum: as of October 2026, Pro-Protect with 24/7 professional monitoring is $24.99 a month ($34.99 with video), and Self-Protect ($14.99) and Video Connect ($9.99) send alerts to you only. ADT's professionally installed plans carry a 36-month monitoring contract (24 months in California) per ADT's residential terms.
