Product image · Source
Reviewers agree: SimpliSafe is easy to install, flexible and strongest when paired with paid monitoring.
What reviewers loved
- Simple DIY installation that CNET calls a 'perfect option for installing a system yourself,' with compact hardware and adhesive mounting that avoids wall damage
- Broad accessory range covering cameras, motion sensors, smoke detectors, water-leak sensors and panic buttons
- Modular starter kits and add-ons make it practical to scale from an apartment to a larger house
- No long-term monitoring contract, with the option to switch between self-monitoring and professional monitoring
- Quick alarm triggering and an intuitive app, according to TechRadar
What held it back
- The total price can climb quickly as sensors, cameras and other add-ons are added
- Trusted Reviews found that the most useful features required the highest subscription tier in its market
- Smart-home integration is limited compared with automation-focused systems such as Abode
- The system offers much less value without a monitoring plan, according to Trusted Reviews

The short version
Critics consistently recommend SimpliSafe to shoppers who want a customizable security system without a long contract or difficult installation. CNET praised its compact hardware, broad sensor range and strong test performance, while TechRadar found the app intuitive and the alarm response quick. The honest trade-off is cost: adding equipment can become expensive, and Trusted Reviews found that important functionality, including app control in its tested market, depended on the highest subscription tier. Smart-home integration is also more limited than with automation-focused rivals.
What reviewers say about the SimpliSafe Home Security System
CNET scored the system 8.5 out of 10 and called it a "perfect option for installing a system yourself." Its reviewers highlighted the compact hardware, damage-free adhesive mounting and strong assortment of battery-powered sensors. TechRadar reached a similar conclusion, rating value, design and performance at 4.5 out of 5 and describing the system as "straightforward and intuitive."
The reservations are mainly about subscriptions and ecosystem depth. Trusted Reviews said SimpliSafe is "brilliant" for buyers willing to pay for its highest monitoring plan, but found cheaper DIY systems offered more free functionality. PCMag likewise praised the affordable, well-designed hardware and flexible monitoring while naming limited smart-home integration as the main weakness. Engadget's Wirecutter partnership also favored SimpliSafe for its reliability, accessibility and no-contract monitoring, although its cited assessment covers an older hardware generation.
Best settings for the SimpliSafe Home Security System
There is no critic-provided calibration guide for this security system. These are CNET's published setup and service options rather than invented alarm settings. Read the full CNET review.
| Mounting method | Attach sensors with the included adhesive strips rather than screws to avoid wall damage and simplify repositioning. |
|---|---|
| Monitoring plan | Start with the $10/month self-monitoring plan; upgrade to the $30/month Guard plan only if you want professional dispatch, based on CNET's listed US pricing. |
Buy it if you want a straightforward DIY alarm with flexible hardware, optional professional monitoring and no long-term contract.
Skip it if you want extensive home-automation support or expect full app-based functionality without a recurring fee.
Also consider
Abode Iota All-In-One Security Kit
PCMag recommends considering Abode when home automation is the priority because it supports several automation protocols and a wider variety of compatible components.
Ring Alarm
Trusted Reviews found that Ring offered more functionality without a fee and a stronger camera range, but its assisted monitoring lacked SimpliSafe's police-dispatch option in the reviewed market.
Should you buy the SimpliSafe Home Security System?
Yes, if uncomplicated installation, expandable sensors and contract-free monitoring matter more than deep smart-home integration. Reviewers broadly agree that SimpliSafe is one of the safer DIY recommendations because it is approachable, responsive and adaptable to different homes. Just price the complete equipment package and monitoring tier before buying; the entry cost is reasonable, but the bill rises with add-ons, and some important functions may sit behind a subscription.
