ADT has 150 years of experience in home security. Its monitoring can handle any situation that arises. ADT’s 12 monitoring centers are open 24 hours a day every day, so your home is covered no matter what happens.
With SimpliSafe, you can choose professional monitoring or self-monitoring. Monitoring services are available 24/7, so someone is always waiting and ready in case an emergency strikes.
Vivint’s multi-layered alarm response that includes text and phone alerts provides speedy responses to potential security breaches. Text alerts often arrive within 10 seconds, providing you and Vivint with the precious extra seconds you might need to call for help.
The best professionally monitored home security systems provide peace of mind that self-monitored systems just can’t touch. You'll pay more monthly, but you'll rest easier knowing trained professionals monitor your system around the clock and can dispatch authorities within seconds when an emergency occurs. After all, when an intruder breaks in or a fire starts, every second matters.
However, not all professional monitoring delivers the same speed and reliability. After extensive hands-on testing of leading security systems, I'm sharing the companies that consistently deliver the fastest emergency response. ADT dominated our testing with its network of 12 monitoring centers, but SimpliSafe, Vivint, and Frontpoint also impressed with their rapid dispatch capabilities. Here's what you need to know.
From Anthony Travaglia, Retired Police Officer, Home Security Expert
The best way to create unbiased and trustworthy reviews is by testing home security systems ourselves. We buy the equipment with our money, install the equipment in our homes, and test them for as long as we need to, even if it takes weeks or months. It’s the best way to get a feel for what it’s like to live with the systems and experience the response times, features, and apps first-hand. We then use what we learn to make our recommendations.
Several factors can impact testing home security systems, so we find ways to compare apples to apples. For example, we test all the equipment in the same house – a two-story, 2,200-square-foot home owned by one of our experts. Testing security systems in a real house helps us capture the most accurate results and give better recommendations.
We even buy the same devices for every security system and set them up in identical locations. You can see the places where we typically put devices below.
We considered multiple factors when narrowing down security companies with fast response times. It’s not just how quickly we get a call from the monitoring center. We’ve used our knowledge and experience in the industry to decide other important factors for these systems, and these are the top three:
Using these criteria, here’s how we landed on the top five.
Rating the Best Security Systems with Fast Response Times
Our experts exclusively cover safety and security equipment, so you’re not going to find reviews for everything here from electric razors to paint brushes like those other review websites. We are experts at testing home security systems only and giving readers reliable and trustworthy recommendations. The team members who worked on this review were:
Our team has over 75 years of combined experience, making us the most accomplished home security team online. Since beginning in 2016, our work has been featured in several major outlets, including The Washington Post and The New York Times. As a team, we have achieved:
ADT knows its stuff. The company has been protecting homes for over 150 years and currently serves approximately 6 million customers nationwide. If you've ever used an ADT system, you'll understand why you see so many of those little blue signs in people's yards. Even with this success, ADT continues innovating. Most recently, they partnered with Google to provide high-quality cameras and smart home integration.
What will you get for that monthly price? A whole lot of protection. ADT has 12 dedicated monitoring centers across the U.S. and Canada, each with its own redundancies built in. When I put the system to the test by simulating break-ins, I measured response times between 30 and 45 seconds — plenty fast when you compare it to the industry standard of about a minute. I was able to cancel each test alarm, but if you were in a true emergency situation, you’d tell the agent the alarm was legitimate, and they would dispatch the authorities.
Preparing to arm my ADT system
I should also mention that I received text alerts before I got the alarm calls. Those were faster by around 20 seconds. I could also cancel or confirm the alarms via text. That’s part of ADT’s SMART Monitoring system, which delivers instant notifications and gives you control right from your phone.
ADT’s monitoring costs depend on the plan and whether or not you had your system professionally installed. Monitoring for self-setup systems starts at $24.99 per month. However, if your system has cameras, you’ll need the Complete Monitoring plan at $39.99 per month. This plan supports full access to ADT’s smart features and unlimited cameras, which makes ADT one of the best security systems for large homes. If your system was professionally installed, the price of all monitoring plans increases by $10 per month.
Did You Know? ADT often runs sales. So, if you think it’s the system for you, but the price tag is a bit of a hindrance, you may want to read my guide to ADT’s deals.
| Equipment Cost | Packages starting at $269 |
|---|---|
| Monitoring Options | Professional or DIY |
| Monitoring Cost | Starting at $24.99 per month |
| Contract Length | Monthly |
| Installation Options | Professional or DIY |
| Smart Platform Integration | Alexa and Google Home |
Looking for something completely different? SimpliSafe swings to the other end of the spectrum, but still offers protections that are every bit as high quality as ADT’s.What do I mean by that? SimpliSafe is one of the best DIY security systems on the market. That means you’ll install and set up the system yourself, and you’ll have a more active role in your protection. But when it comes to monitoring your system, SimpliSafe provides more than enough coverage.
Let’s talk about how SimpliSafe handles monitoring and how quickly the company responds to an emergency. SimpliSafe is one of the best options for self-monitoring, but if you go that route, the response time will depend entirely on how quickly you react to a notification sent to your phone.
Pro Tip: I found myself ignoring notifications when testing self-monitored systems in the past. It’s easy to get into the habit of swiping them away and missing something important.
I clocked SimpliSafe’s response time at 30 seconds flat. That’s very similar to ADT’s time, but I appreciated the video verification element of SimpliSafe’s Fast Protect subscription, giving its agents video access during emergencies. If they see something like broken glass, smoke, or an intruder making off with your TV, they can relay the important details to authorities en route, who will then be better prepared to handle the situation when they arrive at your home.
Similar to a lot of DIY systems, SimpliSafe lets you select from prepackaged systems or build your own using a list of components. I cover all of their equipment options in my guide to SimpliSafe’s prices.
They also offer four options for professional monitoring: standard monitoring at $22.99 per month, and Core monitoring at $32.99 per month, Pro monitoring at $49.99 per month and Pro Plus monitoring at $79.99 per month.
The Core, Pro and Pro Plus plans all include live agent threat deterrence. That allows SimpliSafe’s monitoring agents to view your camera feeds during an alert, assess the situation, and then scare away the threat with your cameras’ two-way audio, siren and lights if needed. The Core plan only enables it for the indoor camera, whereas the Pro and Pro Plus plans bring this feature to the outdoor camera.
Here’s SimpliSafe’s wireless indoor camera which pairs nicely with the Fast Protect monitoring plan.
When I was testing the system, they interacted with me using the two-way microphone and I was able to deactivate the alarm by providing a code word determined when I set up the system. (Don’t forget your code word!)

There’s no question that Vivint is one of the best security systems with home automation. You can clearly see that in the feature-rich Vivint Smart Hub (touchscreen control panel), in the indoor and outdoor security camera with A.I. Smart Deter, and in the customizable Vivint app.When I reviewed Vivint, I was impressed by the quality of the equipment. But I’m not a big fan of Vivint’s 60-month contract or that they give customers only three days to cancel. Other companies like SimpliSafe give users a 60-day refund period; ADT even has a six-month money-back guarantee.
Vivint’s monitoring service starts at $24.99 per month for its base plan. It’s not as good as ADT and its multi-redundant monitoring facilities, but Vivint does have two in-house monitoring facilities.
One of the text messages I got from Vivint during my testing.
As for response times, Vivint was the fastest. Well, that’s only if we count the text-based alerts. In typical security systems, the monitoring center will alert you via call. That usually takes 30 to 60 seconds. But these days, a lot of systems now offer text-based alerts, even ADT and SimpliSafe with Fast Protect. Vivint was one of the first to do it, and Vivint’s text-based alerts are still the speediest. In my experience, text alerts arrive in under 10 seconds, and you can confirm or cancel the alarm right then and there.
Here’s my experience with Vivint alarms:
Like I said, Vivint’s monitoring service starts at $24.99 per month. That’s competitive when you consider that many professionally monitored systems charge similar rates or higher. However, you also need to buy the equipment either upfront or via financing and pay a professional installation fee starting at $99.
Pro Tip: I took up the financing option and was able to spread the payments over 60 months. This can drop package prices to between $10 and $30 per month, which is much more manageable.
While Vivint’s equipment packages start at $199, you need to call them for a custom quote. After all is said and done, most systems cost at least $600. Ours tallied up to over $1,200 which took Vivint out of the running for the best affordable security systems.
| Monitoring Options | Professional only |

| Installation | Professional |
| Smart Platform Integration | Alexa and Google Home |
| Equipment Cost | Starting at $199 |
| Monthly Monitoring Cost | From $24.99 |
| Contract Length | 60 months |
In between SimpliSafe and Vivint, we have Frontpoint. It’s a hybrid security solution that combines the convenience of DIY installation with advanced smart home capabilities. Of course, there’s also optional professional monitoring. During my hands-on review of Frontpoint, I found plenty to appreciate. The installation process is remarkably straightforward, with each component taking just minutes to set up and connect.
Frontpoint only offers one monitoring plan online for $49.99. It’s a comprehensive plan that includes several valuable features — such as text-based alarm verification and intelligent video analytics — which help reduce false alarms. During my testing, I customized camera sensitivity settings and configured activity zones plus virtual trip wires to minimize unnecessary notifications throughout the day.
When an alarm triggers, Frontpoint’s monitoring center reaches out via text or phone call (based on your preference) to verify the event. Depending on your response, they can dispatch emergency services quickly. In my tests, Frontpoint consistently responded within 30 to 45 seconds of an alarm activation. Like SimpliSafe and ADT, the response speed is impressive.
Expert Insight: If you don’t want Frontpoint’s full-featured plan, you’ll need to call them to ask for one of their simpler plans. They even offer self-monitoring plans starting at $4.99 per month if you only want the basics.
Frontpoint’s monitoring runs $49.99 per month, which sits on the higher end compared to SimpliSafe’s starting rate of $22.99 and ADT’s starting monthly base price of $24.99. However, this flat-rate structure means you won’t face increased fees when adding more devices or upgrading your system. Frontpoint’s monitoring cost stays the same regardless of your setup size.

On that note, it’s easy to build a large system with Frontpoint. Starter packages are cheap; even cheaper than SimpliSafe. The smallest bundle costs $79. Comparing Frontpoint and SimpliSafe, the former offers more equipment options, too. It has garage door sensors; SimpliSafe doesn’t.
| Equipment Cost | Packages starting at $69 |
|---|---|
| Monitoring Options | Professional or DIY |
| Monitoring Cost | Starting at $44.99 per month |
| Contract Lengths | Month-to-month |
| Installation Options | DIY |
| Smart Platform Integrations | Google Home, Alexa, and Siri |
We have to give an honorable mention to the security company that sent the cops to my home. While simulating a break-in, I was a little too late to disarm the alarm. The next thing you know, an officer is at my front door checking that everything is ok.
It took about 30 seconds for Cove to respond to the alarm, which is on par with the other security systems on this list. However, it only has one monitoring plan with camera support, which costs $27.99 per month. You also have to pay extra for cloud storage unless you want to use SD cards. So you can see why it didn’t make our top picks.

One thing I want to make clear is that when I talk about response times, I’m talking about the time it takes for the alarm company to get in touch with you to confirm the validity of an alarm, not how long it will take first responders to arrive at your home.
Creating a ground zone for the ADT Outdoor Camera to minimize alerts.
The time it takes for authorities to arrive at your property will depend on multiple factors, including the size of your police force, how easy it is to get to your home, and how busy the police are at the time of the call.
Generally it takes officers 30 to 60 minutes to respond to an alarm, but those response times can speed up greatly depending on the information the alarm company provides. If there is a medical emergency, for example, response will be prioritized.
From Anthony Travaglia, Retired Police Officer, Home Security Expert
Verified response laws were put in place to cut down on wasted police effort. False alarms account for up to 99 percent of alarm dispatches,1 and if police had to respond to every single one, they wouldn't be available to deal with the actual life-threatening scenarios that should demand their attention.
Nearly every alarm company is under some form of verified response law. That means a triggered alarm alone isn’t enough to send authorities. It must be confirmed as an actual event by the homeowner. That’s why response times are so critical. If it takes several minutes for the alarm company to reach out and verify the alarm, it may be too late.
Did You Know? Several security companies offer video verification, where they can access your camera live stream to see if you need help or if you’ve entered the pin code.
When I talk about response times, it’s inevitable that someone will bring up self-monitoring. Don’t get me wrong — self-monitoring is better than nothing, and it certainly has its benefits in terms of costs. I always recommend professional monitoring when possible though. To learn why, check out my guide to ADT vs. DIY systems.
It’s also worth remembering why you got a home security system to begin with. Our recent research shows the top five reasons are:
Simply put, self-monitoring places all the responsibility on you, the homeowner. You have to pay constant attention to your phone to make sure nothing is wrong at home. What if you’re on a road trip or out at the movies? Will you miss an important text that says your motion detector picked up something in the hallway when no one is supposed to be there? It’s better, in my opinion, to leave that responsibility to the professionals and sleep easier at night knowing someone is watching out for you.
After extensive testing, ADT remains the clear winner for homeowners who want the fastest and most reliable monitoring. They operate 12 monitoring centers delivering a consistent 30 to 45 second response time. SimpliSafe delivers exceptional value for DIY enthusiasts with unique live agent deterrence features. If you want high-tech capabilities, opt for Vivint with their fast text-based alerts. Frontpoint sits in the middle with a DIY setup and strong smart home capabilities.
Whichever system you choose, professional monitoring dramatically improves your home security compared to self-monitoring alone. When emergencies happen, those extra seconds of response time can make the difference between a close call and a tragedy.
