Are you looking to secure your home with the right home security solution? If so, you’ve come to the right place.
There are two prominent names that stand out when it comes to home security systems – Alarm.com and ADT. While both companies provide comprehensive security solutions, there is a significant difference in their approaches and features.
In this review, we will do a review on the basic comparisons between Alarm.com and ADT so you can make an informed decision in choosing the ideal home security solution for your needs.
Alarm.com Overview and Packages

Alarm.com is a cloud-based service and technology developer that ties together security equipment from various manufacturers. It offers a home security monitoring platform that is capable of allowing you to monitor your security system from practically anywhere. It gives homeowners integrated access to their alarm system, energy management, access control, and video monitoring which was previously unheard of.
Alarm.com requires professional installation, and different types of equipment are needed for installation. Once installed, all the home security system’s communication is through wireless cellular communicators. This enables users to be protected and connected even if phone or internet lines are being compromised. Likewise, even when there are power outages, the system will continue to function optimally and communicate until the backup battery is dead. That’s about 24 hours in most cases.
Furthermore, this home security solution offers special Crash & Smash protection for each service plan. Alarm systems feature an entry delay which is pivotal in allowing homeowners and authorized users to enter and disarm the system, thereby reducing false alarms greatly.
It also supports both central station monitoring and self monitoring. You can enjoy the added features and peace of mind that central station monitoring offers, with the automatic notifications to the proper authorities in the case of an emergency situation. You can also take advantage of the many features Alarm.com has to offer, such as home automation and energy management or remote video monitoring.
This home security solution has the most robust features for those wanting to self-monitor, including mobile access through their app, notifications directly to cell phones, and remote video and image viewing. Alarm.com also features the first wireless two-way voice-to-compatible panels. This ensures the added benefit of alarm verification through two-way voice without the need for any landlines. Hence, you can reduce the costs of having a landline without needing to sacrifice security.
In addition, it offers a feature called Geo Services. This is another notable feature that will help you in the use of your alarm system. You can set up a “geo fence” that will automatically trigger certain notifications whether you are entering the area of leaving the area. The principle behind this feature is that it uses the location service on your smartphone to make it possible.
It also offers some of the best remote services through any internet-enabled device or computer. As a user of Alarm.com, you can remotely control your alarm and connected devices without losing any capability of the system. This includes features such as adding or removing user codes, arming and disarming, and controlling home automation devices, among others.
In addition to being able to remotely control the system, you can also receive real-time notifications about the events that you consider very important including alarms or a door being left open unknowingly. Even better, you can have a live view of your property remotely through video cameras which also provide access to recorded videos.
Alarm.com Pros and Cons

- Has limited coverage areas in its services compared to ADT. Should you be planning to relocate, you may not be able to access their services in areas it doesn’t cover.
Alarm.com Packages
So, let’s talk about packages. Alarm.com offers three home security system packages, which can be self-setup or professionally installed. You can choose to pay monthly or annually, depending on your preference. As an Alarm.com Premier Partner, Alarm New England offers plans which include:

These service plans the company offers provide increasing capabilities for your system. All plans come with wireless signal forwarding using a cellular radio as well as complete access to the alarm system and alarm notifications.
ADT Security Overview and Packages

ADT is a well-known company that provides both self-setup and professionally installed alarm systems and cameras. The company’s long-term contracts can feel restrictive, but the benefits can be worth it especially if you’re looking for a professionally installed and monitored system from a household name.
The best part is that ADT has been operating for more than 150 years, making it one of the most reputable names in home security. Over the last couple of years, ADT made some pretty big changes which prompted the company to integrate its alarm systems with Google Nest cameras, video doorbells, and smart home devices.
Once installed by a professional installer, ADT’s security system lets you monitor your home effectively. It’s comprehensive too. Across flood sensors, smoke and CO detectors, glass break sensors, and door/window sensors, you’re pretty well covered, whether you’re arming the system for the night or setting it to away mode for a week while you’re away for something important.
You also get some smart home functionality with the platform, as with many modern security systems. For instance, if you find yourself lying in bed, you can check that your smart deadbolt is locked and ensure your thermostat is set to the optimal temperature you like when you’re sleeping. Even better, you can also set and automate routines so devices automatically respond to your behavior.
The center of ADT’s whole system is the control panel, the app, and the online portal. On the control panel, you’re mostly limited to arming your system, checking camera feeds and device states, and activating various routines (such as locking your door and turning off all the lights).
Likewise, in the event of a power outage, your ADT security system will still work. That’s because every ADT control panel comes with a 24-hour backup battery in case of a power interruption. Hence, the platform recommends that you keep the backup battery fully charged so your alarm system still works if the power goes out. Meanwhile, when the backup battery starts to get low, the monitoring center will receive a signal and alert you. This is pretty standard for a professional home security system.
ADT Pros and Cons
Pros
- ADT home security system provides expert installation, ensuring proper system setup and functionality.
- With a large network of monitoring centers, ADT boasts fast response times to alarms.
- As a well-established company, ADT has a strong reputation when it comes to home security.
- Seamless integration with popular smart home devices like Google Nest, allowing voice control and automation.
- Intuitive app for system control and monitoring from anywhere.
Cons:
- ADT’s packages are offered at a low price, but often it’s because the cheapest possible equipment is being offered.
- Users must commit to a contract to access ADT services, which may not be favorable to some users.
- Integrating ADT equipment with other smart home devices can involve multiple apps and be complicated.
- ADT is a national company, meaning they field hundreds of thousands of calls a day. It’s hard to get the same level of service you’d get from a smaller name in the space.

The most basic package, called the Secure Home Package, stops there, but with the option to add additional home security equipment or life safety sensors. The Smart Home Package includes everything in the Secure Package, plus a smart door lock, a smart plug, and the ability to arm and disarm your system from anywhere with the ADT Control App. In addition, customization options include other smart home devices.
Meanwhile, the Video & Smart Home Package includes everything in the Smart Package in addition to an HD indoor camera, a video doorbell camera, the ability to view live video streams remotely, and customizable alerts. In addition, additional cameras and other devices can also be added to this package.
2025’s Key Feature: Mobile App Compatibility

Currently, in 2025, mobile app compatibility has become a cornerstone of home security systems, enabling users to monitor and control their homes seamlessly from anywhere. Both Alarm.com and ADT have prioritized app-driven features, but their approaches differ significantly in functionality, integration, and user experience. Their mobile apps are available for download on both iPhone and Android devices via the Google Play Store and Apple Store.
With the mobile app version of both exceptional security systems, you can remotely control your smart security and home automation devices, and integrate with smart home platforms like Amazon Alexa, Google Nest, at any time from anywhere. This convenience the app provides enhances the overall effectiveness and user-friendliness of both home security services.
Below is an in-depth overview of how these two industry leaders stack up in mobile app innovation.
Alarm.com Mobile App Features
Alarm.com operates as a white-label home security monitoring service, powering apps for third-party providers. Let’s discuss the features its app has to offer below:
1. Multi-Device Compatibility:
Unlike ADT’s proprietary system, Alarm.com’s app works with devices from Honeywell, DSC, and even ADT in some configurations. This universality allows users to mix and match equipment from different brands.
2. Customized Control Automation and Alerts:
The app supports custom “Scenes” to automate security and smart home tasks, such as locking doors and activating lights based on motion triggers. It gives you the option to customize alerts for specific activities, like package deliveries or unauthorized entry.
3. Business and Residential Features:
For businesses, the app enables multi-location management, access control, and employee activity tracking. Whereas, residential users benefit from live video streaming, two-way doorbell communication, and water leak detection .
4. Adaptive Service Plans
Features vary by provider, but the app consistently offers remote arming/disarming, sensor bypassing, and thermostat adjustments. However, advanced functions like video storage or facial recognition require premium subscriptions.
ADT Mobile App Features
ADT’s flagship app, ADT+, has evolved into a powerhouse for smart home management. Key features include:
1. Unified Smart Home Control:
The app integrates with Google Nest products, allowing users to arm/disarm systems, adjust thermostats, lock doors, and view live footage from Nest cameras—all through a single interface. This seamless integration extends to voice commands via Google Assistant to ensure hands-free control.
2. Advanced Automation
The app also gives you the option to create custom “Scenes” to automate routines, such as turning off lights, locking doors, and arming the system when leaving home. Its minimalist design ensures ease of navigation, even for tech novices.
3. Video Verification and Real-Time Alerts:
ADT’s systems include high-definition cameras with motion detection and AI-driven alerts. The app streams live video and sends instant notifications for suspicious activity, which monitoring centers use to verify emergencies faster.
4. Environmental Monitoring:
Beyond security, the app provides alerts for smoke, carbon monoxide, and water leaks, integrating with Nest sensors for comprehensive hazard detection.
What About Security Cameras?

When it comes to security cameras, both Alarm.com and ADT offer robust options, but there are some key points to consider.
Alarm.com has a solid reputation for its sophisticated smart home integration and state-of-the-art camera tech. Their cameras boast high-quality video, AI-driven analytics, and motion detection zones you can tailor to your needs. This makes them a great fit for people who want a more tech-friendly adaptable security setup. Also, Alarm.com’s cameras work with their wider system enabling features like lights or door locks that switch on when the camera spots something.
ADT, on the other hand, provides reliable, professionally installed security cameras with a strong focus on durability and 24/7 monitoring. ADT designs its cameras to work smoothly with their professional monitoring services making sure they quickly deal with any odd activity. While ADT might not have the same AI-powered features as Alarm.com, people know their cameras to be reliable and user-friendly. This makes them a top pick for those who want simplicity and expert help.
