How ADT works
ADT home security systems with professional installation include monitoring, which connects your alarm to a 24/7 monitoring center. If the alarm goes off, an operator will verify the issue and dispatch the appropriate emergency services. In addition to standard home security services, ADT also offers a variety of smart home equipment.
ADT offers several prebuilt packages that can be customized, or you can build a fully custom system. Each package includes an upfront equipment cost and a monthly monitoring fee. Professional installation is available for a fee, but ADT’s packages are also eligible for DIY setup.
ADT cost
ADT home security packages range from $349.00 to $1,593.95, depending on the level of protection and smart home features you want. If you don’t want to pay upfront, ADT offers flexible payment options.
The Security Starter package is the most affordable option and focuses on intruder detection, while Life Safety adds protection against hazards like carbon monoxide. Mid-tier plans like Outdoor Video and Video Essentials include cameras and video doorbells. Front Door Protection adds a smart lock, and Total Safety is the most comprehensive package, with multiple cameras and environmental sensors.
In addition to equipment costs, each plan requires a monthly monitoring fee, typically $24.99 or $39.99, depending on the package.

ADT installation
ADT packages can be installed professionally or set up yourself. For those who choose professional installation, ADT charges a one-time fee that varies according to the package you get, the equipment you select and your location.
Professional installs are handled by technicians. This typically takes just a few hours. The tech will install your sensors and cameras, connect the Base and test everything to make sure it works.
ADT warranties and guarantees
ADT offers several warranties and guarantees:
- Theft Protection Guarantee: Pays up to $500 towards your insurance deductible if a burglary occurs while your ADT system is armed.
- 6-Month Service Guarantee: Refunds the installation price, and pays all monitoring fees if ADT is unable to resolve issues with your system during the first six months.
- Limited Equipment Warranty: ADT will repair or replace any defective equipment at no cost to you during the first 90 days after your order date. You can also extend this plan for a small monthly fee.
ADT FAQ
Where is ADT available?
ADT provides service in all 50 U.S. states and Canada. It has local offices in every state except North Dakota, Vermont and Wyoming.
How do I cancel ADT?
If you purchased your ADT system online, you should be able to cancel your monitoring online using one of the following methods:
- MyADT: Go to myadt.com. Select “Account” then “Manage Subscriptions.” Fill out the cancellation form.
- ADT+: Log in to ADT+, and then select “Billing,” then “Manage Subscriptions,” then “Cancel Subscription.” Fill out the form.
If you don’t see a cancellation form on these pages, you likely didn’t purchase the system online, and you’ll need to call to cancel. The number is 1-800-ADT-ASAP.
Does ADT require a contract?
ADT home security often requires a contract — but not always. In general, if you opt for professional installation, you’ll need to commit to a contract (usually 36 months). If you go with DIY installation, you can purchase just one month.
Does ADT work if my internet goes down?
Generally, yes, your ADT system will still work without internet access. Most systems have a cellular backup for alarms. This generally only applies to monitoring — smart home devices typically need an internet connection to function.
Does ADT work during a power outage?
Yes, ADT can work during a power outage. While the systems typically run on AC power, most have a battery backup ranging from four hours to 24 hours. This will kick in during a power outage to keep you protected.
Is ADT worth it?
ADT is a very solid home security option. It offers modern devices and reliable monitoring. While its pricing is generally higher than many basic or DIY systems, it’s comparable to other professionally monitored services. ADT can be a good option if you want full-service installation and ongoing monitoring.
ADT is especially good for buyers who don’t want to handle installation themselves, since professional setup can save time. Just review the contract terms carefully, as early termination fees can be significant.
