The Best Home Security Systems and Alarm Companies of 2025

What is a home security system and how does it work?

A home security alarm system is a network of integrated devices linked to a central control panel that helps protect against burglaries and other intrusions. The system typically includes:

• A control panel or base station
• Sensors for doors and windows
• Motion sensors
• Glass break sensors
• Security cameras

These components monitor entry into your home and trigger an alarm after a short delay if unauthorized access is detected. This delay allows time to disarm the system to prevent false alarms. If the system is monitored, a professional service contacts you when the alarm is activated.

Home security systems operate in a coordinated manner, with each component communicating its status to the control panel. This information is then relayed to your smartphone and, if subscribed, to a monitoring station. The control panel acts as the central hub, connecting all the components. It can connect via Wi-Fi or cellular data. Hardwired systems use electrical wiring to connect components, while wireless systems utilize radio frequencies or mesh networks for communication.

To help you find a home security system that fits your budget, we gathered prices from 21 top national security companies. We calculated the average costs for monthly professional monitoring, installation and activation fees, and equipment to help you compare your options.

When Vivint switched its focus from smart home to smart security, it was a game changer. If you’re on the hunt for a smart home security system that doesn’t require you to lift a finger, Vivint is the best of the bunch. Vivint’s high-end equipment with pro installation, 24/7 monitoring, smart home features, and state-of-the-art security tech make it the best wireless security system available. 

We love Vivint home security for so many reasons:

• Professional installation that’s more affordable than competitors ($49)
• Financing model where equipment payment and monitoring are separate
• Free in-home security consultations
• Smart home security smartphone app
• Full proprietary equipment line (Vivint doesn’t just rely on other folk’s tech)

Standout feature: Vivint's security cameras with Smart Deter lurker detection are a staff favorite. We love the video doorbell with AI and proactive features (like the whistle) that scare away porch pirates. Learn all about it in our Vivint cameras guide.

Like any luxury item, you’d expect Vivint to come with a luxury price tag. It’s a balance: its equipment is pricey, but Vivint’s monthly monitoring fees remain in line with other top security companies (the U.S. average is $31.99/mo.) The Smart Home Video plan gives you video, smart home control, and integration for about $40 per month.

Our readers have spoken—and they love SimpliSafe’s affordable, straightforward cellular security system. SimpliSafe’s name says it all.

Its security systems are simple—and so is its pricing. SimpliSafe has some of the cheapest monthly monitoring fees available. Plus, you have the flexibility to start or stop your monthly monitoring subscription whenever you like.

If you prefer self-monitoring without a subscription, you can change your plan after the first month—just make sure to call to cancel or change your plan before the 30-day mark. 

SimpliSafe does home security on its own terms. That means ditching some things that turn off customers: brash salespeople and lengthy contracts.

• Professional monitoring service on demand—no contracts
• Rapid SOS gets you help faster
• 60-day money-back guarantee

Standout feature: SimpliSafe has SimpliSafe Active Guard Outdoor Protection. AI and security agents watch over your home and work to scare away intruders before they make any trouble. The only other security system that offers this type of service on our list is Ring.

ADT is the most experienced security company in the country. If you’ll sleep better knowing that a well-known, tried-and-true company is watching over your home, ADT is worth the money.

No one can beat ADT’s experience.

• Top-notch protection delivered for 150 years
• ADT Home Security looks out for more than 8 million people across the globe
• 6 professional monitoring centers
• Partnerships and integration with tech from Google Nest and Ford
• 6-month service guarantee (the longest money-back period in the industry)

Standout feature: ADT Home Security has six redundant monitoring centers. If one monitoring station goes down, your home’s protection transfers to another center. That’s 24/7 protection that you can rely on, even when Mother Nature does her worst.

If you’re going with one of the best home security providers out there, you may as well go all in. The Video and Control bundle includes home automation controls, wireless equipment, and video monitoring, starting around $65 per month (Vivint starts at $45 for similar features). That works out to about $775 a year.

If you have a three-year contract, that's around $2,300 over three years. That may seem steep, but keep in mind that the average loss from one burglary is around $2,600.

You don't have to guess when it comes to home security. Here are the top things to consider before you decide on a system. 

1. What are you protecting? Are you most worried about your property, your pets, your people, your packages, or all?
2. Where are you protecting it? Do you need to keep an eye on things outside or are you more focused on seeing what's happening inside your home?
3. What kind of property are you protecting? Stand alone houses and apartments have different security vulnerabilities. Consider things like the number of ground-level doors and windows, multiple floors and entrances, and outbuildings—like a garage or shed.
4. What's your budget? I always say that you shouldn't have to risk financial security to have home security. Identify your budget before you shop and stick to it. 
5. How hands-on do you want to be? Do you want a system that does everything for you—from installation to professional monitoring? Or is a DIY system more your style, where you can install it and monitor it yourself using a mobile app? Or do you want a little bit of both?

We put in the time to help you find out which home security systems are worth your time, money, and confidence.

We perform hands-on testing and research each system in our roundup. We also talk to the tech teams, CEOs, and other innovators at the companies we review. 

We test security systems in our homes, our friends' homes, and our extended family's homes. We scour customer reviews to capture their experiences and feedback. We compare how each one performs in different settings and to meet different needs. We line up the pricing—upfront, monthly, and over time—to see how much investment you really have to make. 

• 3.9k+ hours of research and testing
• 23 in-home tests
• 21 security systems considered for our top picks

The security systems that make it on our best-of list come from tried and true home security, security camera, or smart home brands. Because home security isn't one size fits all, our best security systems represent a variety of options for homeowners and renters, work for different budgets, and demonstrate a consistent interest in customer and expert feedback.

While our strongest recommendation is for security systems with professional monitoring, we also value systems that offer easy, affordable, and reliable self-monitoring options. 

While we test and research, we look at five primary factors that matter most for protecting your home and family:

1. Costs and contracts
2. Response time and monitoring options 
3. Security features and smart home integration. 
4. Customer service and reputation. 
5. Ease of installation and use.
