SimpliSafe vs. Surety & Alarm.com: Which Home Security System Is Actually Better?
SimpliSafe and Surety (Alarm.com) both show up constantly when people research DIY home security. They look similar on the surface — no contracts, app control, professional monitoring available. But they’re built on fundamentally different levels of quality, and the differences matter a lot depending on what you actually want from a security system.
A quick note on how these compare: SimpliSafe is a single company that makes both the hardware and the software. Surety is a DIY security provider built on top of Alarm.com — the professional-grade platform that powers millions of security systems across the country, including commercial installations and high-security facilities. Alarm.com is the engine; Surety is how you access it without a professional installer or a long-term contract.
SimpliSafe has a well-known reputation as an entry-level consumer system — easy to set up, widely available, and affordable upfront. Alarm.com has an equally well-known reputation as the professional-grade standard. Surety’s mission is to bring that professional-grade quality to DIYers at a fair price. That quality gap is what drives most of the differences below.
Sensors and RF Technology
SimpliSafe’s Gen 3 sensors do use encryption, which is an improvement over older versions that were vulnerable to signal suppression attacks. But the underlying RF technology is still a standard fixed-frequency protocol — which means a determined intruder with a signal jammer can potentially block communications between your sensors and your panel.
Alarm.com-compatible Qolsys panels support PowerG sensors, which go considerably further. PowerG uses frequency hopping spread spectrum — the signal constantly jumps across frequencies, making it extremely difficult to jam. PowerG also has significantly greater range and wall penetration. For larger homes or homes with thick construction, this is a real-world difference. And like SimpliSafe Gen 3, PowerG uses AES-128 encryption throughout.
Alarm.com panels also support hardwired sensors for homes with existing wired security infrastructure — something SimpliSafe cannot do at all.
Home Automation
SimpliSafe has no Z-Wave support. That means no native integration with smart locks, thermostats, garage door controllers, or the broader smart home ecosystem. You can connect some devices through Alexa or Google Home, but it’s indirect — SimpliSafe doesn’t control those devices, it just passes commands through a voice assistant.
Alarm.com has full Z-Wave integration built in. Your security panel is also your smart home hub. Lock and unlock doors from the app. Set your thermostat to adjust when you arm away. Get an alert if the garage door is open when you leave. Create rules that trigger based on time, location, or security events. This is real home automation — not a workaround.
With a Surety Complete plan, you get Alarm.com’s full home automation suite alongside cameras, professional monitoring, and video analytics — all in one platform.
Cameras and Video
Both systems offer cameras with cloud recording, motion alerts, and app viewing. SimpliSafe offers video verification on their Core plan — when an alarm triggers, a monitoring agent can access your indoor camera to confirm what’s happening before dispatching police.
Alarm.com’s video platform goes further in several meaningful ways. First, 24/7 continuous recording: Alarm.com cameras support round-the-clock recording so you can review footage from any point in time — not just motion-triggered clips. SimpliSafe cameras don’t offer continuous recording.
Second, AI Deterrence: Alarm.com cameras can proactively detect and respond to potential threats in real time — triggering lights, sirens, or AI-driven verbal warnings before an incident escalates. SimpliSafe has no equivalent feature.
Third, Familiar Faces: Alarm.com can learn to recognize the faces of household members and trusted visitors, reducing false alerts and giving you smarter, more contextual notifications. SimpliSafe doesn’t offer this.
Overall, user reviews consistently rate Alarm.com’s cameras and video platform higher than SimpliSafe’s on reliability, quality, and feature depth. It’s another area where the professional-grade vs. consumer-grade distinction shows up clearly.
Professional Monitoring
SimpliSafe advertises their Core monitoring plan at $1.10/day — roughly $33.50/month. That’s the plan you need to unlock video features and professional monitoring response.
Surety’s monitoring starts at $19/month, and the Surety Complete plan — which includes home automation, cameras, and the full Alarm.com feature set — is $29/month. That’s meaningfully less than SimpliSafe charges for a comparable level of service, and you get a more capable platform for it.
Equipment Cost
This is where SimpliSafe has a genuine advantage today. Their hardware is less expensive upfront than Alarm.com-compatible equipment from Qolsys or 2GIG. If minimizing the initial investment is your top priority, SimpliSafe costs less to get started.
That said, you get what you pay for — and the quality and capability gap between SimpliSafe’s consumer-grade hardware and Alarm.com’s professional-grade equipment is real and meaningful.
That equipment cost gap is also about to close. Surety is launching a new Alarm.com-compatible system designed specifically for DIY installation — one that will not only match SimpliSafe’s simplicity of setup but also bring the equipment cost much closer to SimpliSafe’s price point, without sacrificing the professional-grade quality underneath.
DIY Installation
SimpliSafe wins on setup simplicity today. Unbox it, peel and stick, done. There’s almost no configuration required. If you want the absolute easiest path to a working alarm system, SimpliSafe gets there faster.
Alarm.com systems require a bit more — you’ll set up a Qolsys or 2GIG panel, add sensors, and configure your account through the Alarm.com app. It’s still very much a DIY installation, and Surety’s support team is available to help. But it’s not quite as plug-and-play as SimpliSafe out of the box — yet. The new system Surety is launching will match SimpliSafe’s simplicity while delivering the full power of Alarm.com underneath.
No Contracts — From Either
Neither SimpliSafe nor Surety requires a contract. You pay month to month and can cancel anytime. This is a genuine advantage both have over traditional alarm companies like ADT and Vivint, and it’s worth acknowledging that SimpliSafe deserves credit for helping normalize the no-contract model.

The Bottom Line
SimpliSafe is easy to set up and a reasonable starting point for basic security. But it’s a consumer product, and it shows — in the sensor technology, the lack of home automation, and the limits of its video platform. And it’s no longer the budget option it once was on the monitoring side.
Alarm.com is what professional installers use. It’s what commercial buildings use. It’s what people who’ve done their homework end up choosing. Through Surety, you get that same professional-grade platform — no contracts, no sales reps, no inflated pricing — at a lower monthly cost than SimpliSafe’s comparable plan.
The upfront equipment cost is higher today, but that’s changing soon. And for most homeowners who are serious about their security, the quality difference is worth it.
