ADT Security System Review
ADT’s groundbreaking features like Trusted Neighbor and strong integration with Google Nest keep it ahead of the curve, but our tests show that ADT is not perfect.


What We Like
- Trusted company: With over 150 years in business, we felt comfortable with choosing ADT right off the bat.
- Smart home integration: ADT works with a variety of third-party smart home products, including Google Assistant and Alexa. These integrations make it possible for users to control their home security system with their voice, or create smart home commands that can make life easier and more convenient.
- User-friendly app: The ADT+ app helps you manage and monitor your ADT and Google Nest equipment.
What We Don't Like
- Professional installation with a fee: If you go with a professionally installed ADT system, you will have to pay a substantial one-time installation fee and more for professional monitoring.
- Restrictive monitoring plans:For security camera support and cloud storage, you’ll need ADT’s priciest professional monitoring plan.
- No touchscreen keypad: Current ADT systems come with analog keypads, which means you won’t be able to control smart devices and monitor cameras with this device.
Bottom Line
There’s no more recognizable home security company than ADT. Our security experts all agree that it’s one of the top options for homeowners right now, especially if you’re looking for a system you can use for years. It’s less flexible than most DIY options, but if you sign up for an ADT system, you’ll get best-in-class equipment, innovative security features, and a user-friendly app to tie it all together.After all these years of testing home security systems, it still shocks us that ADT is one of the oldest security companies in the industry. Yet, instead of struggling to keep up with up-and-coming companies like SimpliSafe and Ring, ADT is innovating and introducing groundbreaking features that raise the benchmark for home security systems.
We’re talking about features like Trusted Neighbor that uses facial recognition to disarm alarms and smart locks, and ADT’s seamless integration with Google Nest products, so we can use the Nest Learning Thermostat to keep our house at the perfect temperature year-round. Our experts are always discovering new improvements when testing ADT security systems. Let’s find out why it continues to be one of the best home security systems we’ve reviewed.

Our Hot Take on ADT Home Security
With a 9.8 out of 10 rating from our team of security experts, ADT is as close to perfect as security systems can be. Our scoring method takes into account factors such as features and pricing, but also our hands-on, stringent review process. And after living with ADT for three months, we concluded that right now, it is the best home security system for most people.
Notably, we found that ADT offers the best equipment options and a reliable monitoring service. ADT also stands behind its industry-leading six-month money back guarantee, which is one reason we found this brand trustworthy.
How ADT Performed
We remember the first time we tested ADT, it still had the discontinued ADT Pulse.1 It featured smart home integrations, smartphone access, and access to ADT security cameras – all were ahead of the curve at the time. But ADT’s current security system takes things further, especially with the addition of Google Nest products.
You’ll still get the smart home integrations and top-of-the-line security equipment ADT is known for. However, you’ll use the upgraded ADT+ smartphone app to manage your ADT devices and Google Nest products. That’s right – no more switching between apps to control different devices.
ADT also upgraded its monitoring network. It had six redundant monitoring facilities back in 2018. Now it has 12 – all with backup generators and servers.
All those prove that ADT never stops improving, but to see how well ADT works now, we have to zoom in further. Up next, let’s talk about ADT’s equipment.
FYI: One of the major upgrades to the current ADT system compared to their older systems is the availability of DIY installation and monitoring options. While this page is all about the professionally installed system we tested (which also requires professional monitoring), you can check out our review of the more flexible ADT Self Setup system.

Components of the ADT Security System
ADT has an impressive catalog of products. But you don’t need one of everything. ADT offers this extensive range of devices so it can protect anything from luxurious mansions to tiny apartments. For our setup, these were the devices we chose:
- Base
- Keypad
- Door/window sensors
- Motion sensors
- Glass break sensors
- Keychain remotes
- Video doorbells
- Outdoor cameras
- Indoor cameras
- Smoke detectors
- Carbon monoxide detectors
- Water and temperature sensors
Base
The Base is the first device the ADT technician set up. It’s the brains of the operation, connecting to the rest of our ADT equipment. It looks like a futuristic router that blends in seamlessly with the decor, so we had no problem putting it on display on a coffee table.
The Base doesn’t have a screen, but there is a keypad for arming and disarming your system. The lack of a touch screen is disappointing, especially after reviewing Vivint’s innovative, touch screen Smart Hub. That said, we appreciate that the ADT base station has battery backup. The battery powers the device for up to 24 hours during outages. On top of that, it can use cellular signals as backup for its Wi-Fi connectivity. These features improve reliability, although it’s worth noting that they’re common to see in the best cellular security systems such as ADT.
Lastly, the base has a ring light that changes color based on the system status. It’s good for anyone looking for a security system for someone hard of hearing.
FYI: The ADT Base has a proximity sensor that lights up when you’re nearby. It also includes buttons for police, medical, and fire, so you can request help quickly.
Door/Window Sensors
When the technician inspected our house, they recommended the best places for our three entry sensors. These devices monitor doors or windows opening and closing and should go on exterior doors and first-floor windows. Interior access doors to garages are also a good idea. For added security, the technician installed one on a second-floor window next to a climbable tree in our backyard.
Take note that we only tested the standard door/window sensors from ADT. There’s also a premium version that costs twice as much, but that one can also detect shock and vibration. If a burglar tries to force their way in – let’s say, by kicking down your door or breaking a glass window – the premium door/window sensors will detect it. We also see them being suitable for cabinets and drawers where you might store valuables like jewelry or firearms.
Expert Insight: Although the FBI no longer includes this in their newer reports, the last data published in 2019 shows that more than half of reported burglaries in the U.S. involve forcible entry.2
Keychain Remote
The keychain remote is one of the reasons we recommend ADT as the best home security system for seniors. Instead of arming and disarming the system with a smartphone app or touchscreen panel, you can use this device. It looks identical to a garage door opener. There is a button for arming the system and a separate one for disarming.
The keychain remote is also good for emergencies. It has a panic button that, when pressed within the base station’s range, calls ADT’s monitoring center for help. We haven’t had the chance to use the feature in a real emergency, but we think it could be useful for household members with medical conditions.
Motion Detector
Motion detectors use passive infrared to detect moving subjects that emit body heat, like humans or pets. The ADT motion sensor has a 90-degree horizontal and 50-degree vertical field of view, which was more than enough for our living room.
If you have pets, you can adjust the sensitivity to make it pet-friendly, meaning, pets’ movements won’t trigger it. Set to the lowest sensitivity, it was able to ignore our 65-pound Labrador Retriever, but the technician told us it can ignore pets up to 85 pounds. Of the security systems we recommend to pet owners, ADT’s motion sensor is the most friendly to large pets.
Pro Tip: You can set the motion sensors to Convenience Mode which sends a notification to your phone when motion is detected without triggering the alarm
Glass Break Sensors
ADT’s glass break sensor has a 25-foot range at maximum sensitivity, but if you’re like us and tend to be clumsy with glasses, you can adjust it with four sensitivity levels. Our ADT install technician placed the glass break sensor opposite our sliding glass doors leading to the patio as it works best facing the source.
FYI: An alternative to installing a glass break sensor is using the Google Nest Hub Max’s sound-detection feature, which alerts you when it hears glass breaking. You need a Nest Aware subscription to enable this feature, but as you’ll soon find out, ADT’s top-tier monitoring plan includes Nest Aware at no added charge.
Smoke Detector
We can assure you that the ADT WiFi smoke detector works. How do we know? Well, we accidentally burned some toast one morning and were serenaded by the blaring sounds of the alarm. The ADT monitoring team also got an alert and checked in with us to make sure everything was ok.
We’re glad we did this “test.” Because of it, we discovered that ADT smoke alarms are interconnected, meaning, if one goes off, all the others installed in your home go off too. That’s a small but potentially life-saving feature. No matter where the fire started, everyone in the house will be made aware.
FYI: If you already have smoke alarms and don’t want to change them all to ADT’s smoke detectors, we suggest putting up ADT’s security cameras instead. The Nest Cam (indoor) and Nest Cam (battery) have sound detection that can alert you when a smoke alarm or gas leak detector goes off. The alert doesn’t go to the monitoring center, but at least you’d be notified wherever you are.
Carbon Monoxide Detector
While we installed ADT’s carbon monoxide detector, we couldn’t safely test it. What we do know is that the device is tamper-proof. It also has an LED light to indicate the alarm condition. When it’s green, everything is functioning normally. A blinking amber light means the device requires maintenance. The light flashes red when it detects carbon monoxide. There is a hush button to silence the device for five minutes in case there’s a false alarm.
FYI: ADT also offers other smart home products like smart light bulbs, thermostat, plugs, and garage door controls, but since they’re only tangentially security-related, we didn’t test them out for this review.
ADT Security Cameras
ADT has upgraded its security camera lineup with products from the Google Nest range. This includes the Nest Doorbell, which features on our list of the best video doorbells. Here are the security cameras on offer.
Google Nest Cam Options from ADT
The Google Nest security cameras are on our list of the best security cameras because of their impressive video quality (1080p HD with HDR) and their artificial intelligence. The AI allows the cameras to recognize faces, so whenever our sitter comes to our house, the Nest Cam assures us that it’s not a stranger. There are four models available to purchase from ADT:
- Nest Cam (battery): Easy to install inside and outside and has a 130-degree field of view. It’s battery-powered, so you don’t have to worry about plugging it in.
- Nest Cam (indoor, wired): It has a slightly wider field of vision than the battery-powered model, but it only works indoors and needs to be plugged in.
- Nest Cam with Floodlight: This outdoor camera has two protruding floodlights that you can control via the app, but the whole unit needs to be hardwired into a junction box.
- Nest Doorbell (battery): This doorbell camera features a 145-degree field of view and a 960 by 1280 resolution. Because it’s battery-powered, you don’t need existing doorbell wires.

ADT + Nest Cam – Additional Features
If you decide to go with one camera or the entire range of Google Nest camera products, similar to Vivint’s packages, you’ll only have one monitoring plan to choose from. Unfortunately, it’s the most expensive option.
However, we think you get your money’s worth. The Complete plan includes up to 30 days of cloud storage for all your Nest cameras. Normally this requires an $8 per month Nest Aware subscription. The plan also includes smart home automation like scheduling alarms or turning on lights when motion is detected. You even gain other smart features including AI detection, facial recognition, and sound detection.
Pro Tip: If you currently have Nest Cams and a Nest Aware subscription, go ahead and cancel it. Signing up for ADT’s top-tier monitoring plan and linking your Nest Home account will reactivate the subscription without added fees. Nest Aware is included in ADT’s highest monitoring plan.
The Complete plan also includes video verification. When an alarm occurs, ADT monitoring agents check your camera’s live feeds to confirm if you accidentally tripped the alarm or if they should send help. This verification typically speeds up police response times.
There’s one more feature – called Trusted Neighbor – that deserves its own section. That’s next.
What is Trusted Neighbor?
Trusted Neighbor uses Nest’s facial recognition technology to unlock smart locks and deactivate your security system. You can register and authorize regular guests like friends or family members, and when they approach your home, the system sends their phone a notification to gain access.
You can set time-based and event-based rules to decide when each ‘trusted neighbor’ is allowed entry. For example, we set ADT Plus to let our babysitter into the house between 4 and 5 P.M. to look after the kids. For event-based rules, you can set your system to only let people in when your smoke alarms detect fire – to let your pets out, for example.
FYI: Trusted Neighbor is a great feature, but SimpliSafe’s Intruder Intervention might be better. When we reviewed SimpliSafe, we witnessed SimpliSafe agents access our security camera’s two-way audio speaker to check in on us after we accidentally tripped the alarm. It made us jump a little, so imagine how a burglar would feel.
Home Automation with ADT
ADT, with its integration with Google’s smart home ecosystem, easily made our list of the best smart home security systems. But how well does ADT’s home automation work? We’re here to tell you our experience.
First off, we were able to control ADT with our voices. We mainly used Google Assistant via the Nest Hub we tested previously, but you can also use Alexa-enabled devices. Simple commands like “arm my system” worked flawlessly, but since ADT’s base station also functions as a smart home hub, we were able to control other connected devices. For example, you can ask your voice AI to lock the door if you have a smart lock connected to ADT, or to set the temperature if you have a connected smart thermostat.
Pro Tip: If your smart devices integrate directly with Google Assistant or Alexa, it’s better to control them directly instead of via ADT. Some commands require you to say additional commands (i.e. “ask ADT to…”), so native voice assistant integrations always work better.
We should also point out that as a smart home hub, you can use ADT to create automated rules, similar to how IFTTT works. That means you don’t need an IFTTT-compatible system to make your lights turn on when the front door is opened. You can create these automations using the ADT+ app.
ADT’s automated rule recipes consist of three ingredients – a trigger, an action, and conditions. For example, we want all our lights to turn on when smoke is detected. That way, in case of fire, we could easily find our way out. To set that up, we set the smoke alarm as the trigger device, activating the automation when smoke is detected. Then, we simply selected all our Z-Wave smart lights as the action devices, setting them to turn on when the trigger occurs. We skipped the conditions for this one, but you can set exceptions like time of day (or days of the week), when the system is armed or disarmed, etc.
These automation rules put ADT in the same level as abode (see our abode review) and Vivint in terms of smart home capabilities. We recommend exploring the automation features and to come up with your own automations to make your home safer, more secure, and smarter.
ADT’s Monitoring Plans
That ends our discussion about ADT’s equipment. Now let’s move on to monitoring.
You can self-monitor your ADT system if you install the equipment yourself, but for those who will opt for professional installation like us, monitoring is required. And yes, there’s a monthly fee attached to it. Also note that monitoring plans for professionally installed ADT systems cost more than the plans for DIY systems.

Secure | Smart | Complete | |
---|---|---|---|
24/7 intrusion, fire, emergency monitoring | Yes | Yes | Yes |
SMART Monitoring | Yes | Yes | Yes |
ADT mobile app | Yes | Yes | Yes |

Monthly price for Self Setup customers | $24.99 | $29.99 | $39.99 |
Monthly price for professionally installed systems | $34.99 | $39.99 | $49.99 |
The top-tier option with video security offers the best value because it includes a Nest Aware subscription for the Nest Cams, which goes for $8 per month when bought directly from Google. Learn more about Nest Aware subscriptions here.
You can also add a Quality Service Plan (QSP) which is an extended warranty plan for your equipment starting at $7 per month. Just keep in mind that the cost of the QSP scales with the number and type of devices you have.
Truth be told, those prices aren’t the lowest in the industry. If you’re looking to save money, there are companies that offer monitoring for as low as $19.99 per month (looking at you, Cove! Read more in our Cove review.) You could even consider SimpliSafe if you want a security system with advanced monitoring features at a similar price.
That said, ADT’s pricing isn’t half bad. It actually falls around the industry average, and it could make sense to go with ADT despite it seeming expensive if you’re looking for premium professional monitoring and cellular backup. Besides, there are ADT deals all throughout the year to help you offset the cost.
Is ADT Monitoring Worth It?
There are plenty of reasons why we think ADT monitoring is worth it – but two stand out the most. First, when we tested ADT’s monitoring service by triggering the alarm several times throughout our testing phase, it gave us a response time of more or less 30 seconds each time. That’s the industry average, and although there are faster systems out there, we consider 30 seconds to be the sweet spot. It gives you enough time to cancel the response call if it’s a false alarm, but not too long that it gives burglars a chance to take your stuff and bolt.
Second, ADT has 12 fully-redundant monitoring centers. The significance of that is even if one facility fails to operate – for example, if there’s a natural calamity in its area – ADT’s monitoring will continue. These 12 facilities are spread out throughout the U.S. and Canada, and they are all linked together.
Our Experience: ADT also has a monitoring feature called SMART Monitoring, which uses text-based alerts. These alerts are sent to all household members within 10 seconds of an alarm. They include a link to a group chat, where members can collectively decide whether to send emergency help or waive off the alarm. If no action is taken in roughly half a minute, only then will ADT proceed to call the registered phone numbers to check on things.
Our Installation Process with ADT
ADT no longer requires professional setup with the new ADT system, but it’s still available for an extra cost if you need a hand. However, you’ll need to call ADT to get a quote and finalize the purchase of your system.
Previous ADT Black Friday and Cyber Monday deals have included free video doorbell installation, but we’ve never seen full-system installation available. That’s not to say you can’t get a good deal. Installation costs start at about $100, but we’ve successfully negotiated rates with ADT sales teams. So it doesn’t hurt to ask for free installation when you’re discussing system costs.
We can’t fault ADT’s professional installation service. The technician arrived on time, acted professionally, and completed the installation in about an hour. ADT told us in advance to set aside at least a two-hour window in case the technician runs late or the installation takes longer, but we didn’t expect the installation process to be that fast and efficient.
ADT Apps
You might have seen a few ADT apps on the App Store and Google Play. It’s ok, they’re all official. ADT Pulse and ADT Control are for customers who have been with the company for a while. But all new customers will download ADT+.
You can use ADT+ to set up, control, and monitor all your equipment. It can even help you add compatible third-party devices. We used ADT+ mostly during our testing of the ADT Self Setup system. The app guided us through how to install and configure each device. It also performed tests to make sure we did it right. Thankfully, we did.
ADT+’s greatest feature is how it’s incorporated Google Nest. You can use it as a substitute for the Nest App, so you’re not switching between screens to manage different devices. We could view Nest Cam footage and recordings, control our Nest smart home devices, and manage the security system including features like Trusted Neighbor.
ADT’s Customer Support
You can contact ADT 24/7 via phone, email, and live chat. Alternatively, you can search for an answer yourself in their knowledge center. This is sometimes the best option as we’ve had mixed experiences with the support team. During a live chat, someone sent a link to a page that had nothing to do with our question. But then another time we had amazing support while we were trying to set up a motion sensor. So we can’t say that ADT is one of the worst security systems in the market.
Tip: If you need help with ADT, use live chat before you call them over the phone.

Recap of the ADT Security System
While it’s not the most flexible home security system in town, ADT is heading in the right direction. The company has ditched long-term contracts, and professional installation and calling ADT are optional. The addition of a user-friendly, all-in-one app for ADT and Nest features, like Trusted Neighbor, helps solidify its spot on our best home security system list.
But it’s not perfect. We wouldn’t recommend ADT if you’re looking to monitor the system yourself. It’s also not the cheapest option on the market, despite lacking a touch screen controller. However, ADT offers good bang for your buck, and we can’t wait to see what comes next.
ADT FAQs
-
Can I use ADT without professional monitoring?
ADT has a self-monitoring plan with basic features like receiving system alerts, but only if you self-install the system. Professionally installed systems don’t get this option. However, we recommend a professional monitoring plan anyway to gain cloud storage for video recordings, smart home integration, and Trusted Neighbor.
