Best Cellular Security Systems
Cellular backup keeps your home security system on even if the power goes out; here are our favorite systems with cellular backup available.


Experienced burglars are quick and efficient. They can be in and out of homes in just a couple of minutes. That means, if you want to protect your home, you need a security system that is just as quick and reliable.
When a security system detects an intrusion, it initiates an alarm process that starts by sending alert signals to you or your monitoring provider. This signal travels either through the internet, landlines, or cellular signals. And while all these modes of communication are fast, only one is perfectly reliable: Cellular signals.
Cellular signals are the same signals our phones use to send texts or place calls, and besides being fast, they are much less prone to downtimes than landline and Wi-Fi connections. That’s why cellular monitoring is the gold standard of today’s security systems.
But of all the companies that offer cellular monitoring, which is the best? We’ll answer that in this guide, so keep reading for the best cellular security systems.
Cellular security systems | Typical length of professional monitoring contract |

SimpliSafe | 1 month |
ADT | 3 years |
Vivint | 4-5 years |
Cove | 1 month |

Detailed List of the Best Cellular Security Systems
-
1. SimpliSafe - Best No-Contract System
SimpliSafe is a longtime leader in wire-free home security systems. They sell high-quality equipment at low prices, and no payment is needed to keep a SimpliSafe alarm system running. However, it’s only with paid monitoring that SimpliSafe uses cellular signals to send alerts; without a monthly payment, your SimpliSafe system will communicate over home Wi-Fi.
Professional monitoring from SimpliSafe is affordable. The Standard plan costs $17.99 per month, while the Interactive plan costs $27.99 monthly. Both plans offer cellular backup. The keyword there is “backup.” By default, SimpliSafe uses your home Wi-Fi to send alerts, but if the system notices that your internet connection is spotty, it switches over to cellular mode.
SimpliSafe is designed for simple do-it-yourself installation. No tools are required unless you install the SimpliSafe video doorbell, which calls for a Phillips. It shouldn’t take more than 30 minutes to set up a basic cellular security system with entry sensors, indoor motion sensors, freestanding camera, and wire-free keypad.
SimpliSafe Video Doorbell Pro Cellular Coverage, Prices, and DIY Installation
Along with an award-winning monitoring center, what makes SimpliSafe one of the best cellular security system brands? An expansive cellular network, low prices, and easy DIY installation make SimpliSafe a great value for millions of households.
- Expansive Cellular Network – The cellular chips in SimpliSafe security systems can communicate over networks used by Verizon and T-Mobile. This helps make cellular home security available across virtually all the USA. Before buying a SimpliSafe set, you can call the company and verify that cellular security service can be activated at your address.
- Low Prices – SimpliSafe prices are relatively low. That’s true of the equipment and optional cellular monitoring. For equipment, customers get factory-direct deals and can also buy refurbished security systems with long warranties included. The cheapest SimpliSafe starter kit costs about $200, but with SimpliSafe deals, you can often snatch one for less than that.
- Simple DIY Installation – As you’d expect from the name, SimpliSafe is simple to install yourself. Each system arrives with a thumb drive that guides you through tool-free setup. Most equipment is freestanding or can attach to flat surfaces with removable adhesive strips. For instance, you don’t need to plug-in or hardwire SimpliSafe motion sensors; their batteries can last for up to seven years.
SimpliSafe’s stand in terms of monitoring contracts is also worthy of praise. To live up to its promise of “simple home security,” SimpliSafe doesn’t require customers to sign a contract. After buying the equipment, customers can opt in and out of professional monitoring anytime they want. With more traditional security systems, a contract is required, and opting out while there’s an active contract would result in hefty penalties.
Let’s talk about SimpliSafe’s monitoring plans. The Standard plan costs $17.99 per month and includes the features you’ll need to self-monitor the system and professional monitoring. You’ll be able to receive smartphone alerts, control your home security using the app, and even livestream camera feeds to your phone. However, home automation, cloud storage, voice control via Alexa and Google Assistant, and other premium features are reserved for users on the Interactive plan. This plan costs $27.99 per month.
Without a plan, SimpliSafe is a self-monitored security system. The monitoring center will not be involved in any alerts coming from the system, which means it will be up to you to contact the authorities in case of an emergency.
You will still receive mobile alerts though, although with the cellular chip rendered inactive, SimpliSafe will have to notify you through your internet connection. That’s fine as long as your internet is reliable, but when it’s down, the only defense you have left is the integrated Siren. Is that enough? That’s up to you to decide. Personally, we prefer having more than just a siren.
SimpliCam Any drawbacks? There are. SimpliSafe isn’t the top choice for video monitoring. It does offer an indoor camera, an outdoor camera, and a video doorbell, but if you’re looking for sophisticated video surveillance and monitoring, they aren’t the right cameras for you. You’re probably better off buying a dedicated security system from an established security camera brand like Lorex.
SimpliSafe also falls short when it comes to home automation. It relies on integrations with third-party smart home products, and right now, the list of compatible products is short.
What We Like
- Affordable equipment
- Simple DIY installation
- Affordable monitoring for police/fire/medical emergencies
- Intrusion protection, environmental safety, and home automation
- Monitoring not required
- No credit check
- Works with Amazon Alexa
What We Don’t Like
- Cameras are too simple and don’t have artificial intelligence
- No continuous video recording (Only motion-triggered)
- Does not support Z-Wave
SimpliSafe customers tend to be very satisfied. Customers get a 60-day money-back guarantee, and equipment is under warranty for up to three years.

2. ADT - Best Professionally Installed System
ADT is America’s longest-established home security company, and with their ADT Pulse or ADT Control products, they provide the best professionally installed cellular security systems.
ADT is the best professionally installed cellular system because of two things.
First, you’ll enjoy generous buyer protections, like its six-month money-back guarantee. With this, if something goes wrong with the system and ADT fails to solve it within the first six months, you’ll get your installation and monthly fees back.
Second, ADT is efficient at installing security systems. They send only trained technicians to install security systems, ensuring the quality of installation. Once the system is up and running, the technician will even hang around for a few minutes to explain how the system works.
Each ADT system is customized to the customers’ security needs. The technician can install a basic setup if you so please, or they can install a full-on smart home security system complete with smart home products like smart thermostats, smart locks, and other components. You can also integrate existing smart home products with ADT as long as they are Z-Wave compatible. The ADT mobile app ties everything together, so you can control your home with your fingertips.
ADT Samsung SmartThings Starter Kit Because of ADT’s professional setup, you can expect advanced features from this cellular security system. Remote control options are available with the ADT Control app, for example, with which you can control your system from anywhere in the world.
You can also integrate voice control using Alexa or Google Assistant. Just say, “Alexa, arm the system,” or “OK Google, dim the lights,” and ADT will make the necessary adjustments for you.
That said, ADT is not perfect. Unlike SimpliSafe that lets customers choose between professional and self-monitoring, ADT requires professional monitoring. Moreover, there’s a long-term contract that needs to be signed. This contract can be anywhere from two years to five years, depending on your equipment payment plan.
Speaking of equipment payment, you can get an ADT system without upfront equipment fees through financing. You can pay as low as $11 per month for a basic security system over the course of three years. This is on top of the monthly monitoring fee.
What We Like
- Same-day professional installation
- Pro monitoring to send police, firefighters, and paramedics
- Works with Alexa and Google Assistant
- Intrusion protection, environmental safety, and home automation
- Hub supports Z-Wave devices
What We Don’t Like
- 720p camera resolution (Crisp, but higher resolution is available)
- Continuous video recording not included (Motion-triggered only)
- Prices not advertised
In any case, ADT is flexible. It caters to every customer’s unique security needs, and with its top-notch professional installation service, we’re giving it the award for the best professionally installed cellular security system.

3. Vivint - Best Smart Security System
Vivint is another option that provides best-in-class professionally installed cellular security systems, but what sets it apart is the unique way it approaches home security: By adding “smarts” to its security system.
Vivint is the best smart security system with cellular monitoring because it uses a variety of modern technology to secure homes. You can add security cameras for indoor and outdoor surveillance. By default, the Vivint video doorbell will store 30-second clips triggered by motion, each with a snapshot summary. Other Vivint cameras will store images and 90-second clips by default. As an option, you can set up a local smart drive from Vivint where cameras can store rolling videos.
The best smart camera from Vivint is by far the Vivint Outdoor Camera Pro. It’s a sturdy outdoor camera that uses artificial intelligence to detect if there’s someone lurking within or close to your property. If it detects someone, it flashes red lights automatically and will issue an audible warning. The newest version also comes with a microSD card slot, so it can store videos even if your internet is down. It complements Vivint’s cellular monitoring well.
Along with a cell chip, a Vivint home security hub has a Z-Wave radio chip. This lets you incorporate an endless variety of smart home devices by third parties. Examples are smart outlets, smart dimmers, and remote-controlled window coverings.
Vivint security plans are relatively affordable considering their high-quality features. Prices are currently unadvertised at the Vivint site. However, in our experience, the cheapest plan costs just $29.99 per month. For $39.99/month you’ll get remote control over your home with Google Assistant and your smartphone.
Any downsides? Well, besides the expensive equipment prices, Vivint customers have only three days to reconsider their purchase — very short compared to the industry standard 30-day return policy. In addition, Vivint uses proprietary equipment. Once your contract is over and you don’t renew, no other alarm company that we know of can monitor your Vivint equipment, so it becomes essentially useless.
What We Like
- Pro installation
- Pro monitoring to send police, firefighters, and paramedics
- Intrusion protection, environmental safety, and home automation
- Works with Google Assistant
- Supports Z-Wave
What We Don’t Like
- Proprietary equipment
- No free trial
All in all, Vivint is the best choice for cellular home security with virtually unlimited home automation. You’ll need to pay each month for service though; unlike the SimpliSafe siren, a Vivint siren won’t sound unless connected to emergency dispatchers. Energy savings and a Vivint-related discount on homeowner’s insurance might help offset the monthly cost.
-
4. Frontpoint - Best DIY Installed System
Frontpoint is the best choice for people seeking expert cellular security monitoring but do-it-yourself installation. Systems can be monitored by Frontpoint’s partner, Rapid Response Monitoring Services, with month-to-month or annual agreements. Among Rapid Response’s accolades are accreditation from the Department of Defense and the New York City Fire Department.
Installing a 100% cellular security system is easy; like SimpliSafe, Frontpoint provides equipment that you can set up without tools. Also, Frontpoint lets you move your cellular security system to a new address for no charge. Each cellular security system with a Frontpoint Smart Hub can automatically move to Wi-Fi if cellular towers are unavailable.
Pricing for Frontpoint cellular security systems starts at $129 for equipment, plus $49.99 monthly for professional monitoring. Being the only professional monitoring option from Frontpoint, the $49.99 plan includes every feature in Frontpoint’s arsenal: Crash and Smash protection, video monitoring, smartphone remote control, and Google Home and Alexa integrations. The plan also lets you add automation devices such as smart locks and smart thermostats.
Frontpoint finds that customers save up to 20 percent on home energy bills when a smart thermostat is included, so this helps offset the home security expense.
Why choose Frontpoint over SimpliSafe? One advantage is outdoor video surveillance; Frontpoint has weatherproof security cameras. Another advantage is Frontpoint’s Z-Wave radio chip. With Z-Wave and the Frontpoint app, you can easily integrate gadgets from third parties. Adding a component takes about 10 minutes.
Frontpoint Premium Indoor Camera Why choose Frontpoint vs ADT? Frontpoint publishes all its prices, and you can choose a month-to-month service instead of signing a contract. Since you’ll purchase Frontpoint equipment outright, you won’t need a credit check either.
What We Like
- Upfront pricing
- DIY installation
- Pro monitoring to send police, firefighters, and paramedics
- Intrusion protection, environmental safety, and home automation
- Cellular with Wi-Fi backup
- Weatherproof security cameras
- Alexa & Google Assistant
- Supports Z-Wave
- Great customer service
What We Don’t Like
- Cheaper systems are available
- Frontpoint equipment is under warranty for up to three years. Systems carry a 30-day money-back guarantee.

5. Cove - Most Affordable System
Typically, cellular monitoring costs more than landline monitoring. However, with Cove, you don’t have to pay a premium price to enjoy the premium protection that cellular systems provide. When we dug deeper into Cove’s pricing, we were pleased to find their professional monitoring through cellular signals starts at only $17.99 per month. For that price, you’ll get a team of trained monitoring center agents monitoring your system 24/7 for any disturbances, including break-ins, fire, and even medical emergencies (if you spring for all the options, that is).
If you want to get most out of your system, though, you might want to consider upgrading your monitoring plan to Cove Plus. For $27.99 a month, Cove Plus adds in security camera integrations, smartphone control, Alexa and Google Home automations, and a seven-day cloud video storage. Considering that most security companies charge around $50 a month for those features, the extra $10 per month is well worth it.
What We Like
- 24/7 monitoring and cellular backup
- RapidSOS monitoring technology
- Works with Alexa and Google Assistant
- Affordable plans
- DIY Installation
- No contracts
What We Don’t Like
- No self-monitoring option
- Limited equipment options
- Mobile smartphone controls cost $24.99 per month
Cove’s affordability extends to its equipment as well. Keep in mind that Cove’s equipment is entirely wireless, and that all pieces are monitored through the cellular-ready touchscreen panel. With cellular systems, we usually see sensors sold for $30 to $75 a piece, depending on what the sensor does. But with Cove, the most expensive sensor, which is the smoke and carbon monoxide sensor, retails for only $55. And if you purchase your equipment up-front, you’ll get a 50-percent discount. Entry sensors, motion sensors, and glass break sensors all retail for less than $20, including discounts. And one more thing: You’ll get a free indoor camera worth about $100 with any purchase of a security system, not bad at all.
With those prices, you can get a basic Cove system for less than $200 (discounted price). However, if you don’t want to shell out that amount up-front, Cove also offers a flexible payment plan. You will receive up to $450 worth of equipment (retail price) without initial payments in exchange for a 36-month professional monitoring contract and a $10 increase in your monthly payment. Over the course of three years, you will only have paid $360 for the equipment, so we think that’s a fair ask.
Did You Know: Cove offers something called RapidSOS with their cellular monitoring services. RapidSOS allows for Cove’s monitoring center to redirect your alarm signal straight to dispatchers, which should help to improve response time.
FAQ

-
What are the best cellular security systems?
The best cellular security systems are ADT, Vivint, Cove, Frontpoint, and SimpliSafe. Overall, we liked ADT’s professional installation and monitoring the most, as it provides a high level of security that many DIY systems fail to provide. But really, the best cellular security system depends on what you’re after, so here’s what we liked best about our top picks.
- SimpliSafe: No-contract and affordable monitoring
- ADT: Professional installation and monitoring
- Vivint: Home automation and security cameras
- Frontpoint: DIY installation and great customer service
- Cove: Affordable monitoring and equipment
-
How much do cellular security systems cost?
Cellular security systems cost around $200, typically, depending on the brand, the size of the system, and the technology. In most cases, you can have your security system financed by the alarm company’s financing partner, which will divide the cost into 36 to 60 monthly installments. Aside from the equipment cost, there will be a monthly charge for professional monitoring. The cost also depends on the company offering the service, but among our top picks, Cove and SimpliSafe have the lowest monitoring prices, both starting at $17.99 per month. ADT, Vivint, and Frontpoint monitoring all fall within the $40 to $60 per month price range.
-
Do you need a landline or internet connection to use cellular security systems?
You don’t need a landline or internet connection to use cellular security systems. They use built-in cellular chips to communicate alerts to monitoring centers. However, there are security systems that use two or more communication methods. In such cases, you can connect the security system to your landline or internet and it will use its cellular chip as backup.
-
Can you use cellular security systems without a monthly fee?
You can use cellular security systems without a monthly fee if the alarm company allows self-monitoring for free. With a self-monitored system, the user is responsible for resolving alerts, including calling the police if necessary. However, to make the most of the cellular feature, we recommend getting professional monitoring. Cellular systems communicate with monitoring centers through a cellular chip, which will continue to work even without a landline or internet connection.
