The Short Answer
ADT is worth it if you own your home, plan to stay at least three years, and want professional installation plus 24/7 professional monitoring with cellular backup. It is usually not worth it if you rent short-term, may move soon, or only want a camera you check yourself, because ADT's published terms describe a 36-month contract (24 months in California) and an early exit can cost 75% of the remaining monthly charges.
A disclosure up front: NetSecure360 is an authorized ADT dealer headquartered in Camp Hill, PA, serving homeowners nationwide. We have a stake in your answer, which is exactly why the cons below are written as plainly as the pros. A customer who signs a three-year agreement that does not fit their life is not a good outcome for anyone.
What You Are Actually Paying For
An ADT-powered system has three cost parts: the equipment, the installation, and a monthly monitoring charge. The equipment is sensors, a control panel, and any cameras or smart devices you add. The monthly charge pays for people at ADT's professional monitoring centers to respond to your alarms 24/7, including fire and carbon monoxide alarms when nobody is home. That monitoring is the part a DIY system does not include unless you add a paid plan, and it is the main thing you are deciding whether to pay for. For how the response actually works, see how home security monitoring works.
We do not publish a fixed price, because the total depends on your home and the equipment you choose. Right now, qualifying new monitoring agreements get $0 upfront, with up to $1,500 in equipment and installation costs covered. Terms and conditions apply.
The Pros
Alarms go to ADT's professional monitoring centers around the clock, so someone responds even when you are asleep, at work, or away without your phone.
A certified technician places and tests every sensor. Nothing depends on you getting the setup right.
Monitored plans include cellular communication, so cutting a phone line or losing Wi-Fi does not silence the system.
Monitored smoke, heat, and CO sensors alert the monitoring center even when nobody is home to hear the alarm.
Nest cameras, a video doorbell, smart locks, and a smart thermostat can run in the same system and app.
ADT traces its history to 1874, which makes it one of the oldest names in the industry.
The Cons
ADT's published terms describe a 36-month monitoring contract (24 months in California). That is a real commitment.
Under those terms, cancelling early can cost 75% of the monthly charges left in the initial term.
You pay every month for people to watch your alarms. A self-monitored DIY camera costs less, and does less.
The six-month money-back guarantee only applies when ADT cannot resolve a system issue. It is not a free trial.

ADT's published residential terms describe a 36-month monitoring contract, or 24 months in California. If you cancel early, ADT may charge 75% of the monthly service charges due for the balance of the initial term. Put simply: cancel with 12 months left, and you may owe up to 75% of those 12 months of monitoring. That is the single biggest reason ADT is not worth it for someone likely to move soon.
The six-month money-back guarantee is real but narrower than it sounds. ADT's terms say it applies only after ADT has made attempts to resolve a system-related issue and could not resolve it within the first six months after activation. Agreements can vary, so ask for the exact term, early termination calculation, and guarantee conditions in writing before you sign. Our questions to ask before signing a home security contract covers the full list.
Who ADT Is Worth It For
| Your Situation | Verdict |
|---|---|
| You own your home and plan to stay 3+ years | Usually worth it |
| You want someone else to install and test everything | Usually worth it |
| You travel often or have family who cannot respond to alerts | Usually worth it |
| You want monitored smoke and CO protection | Usually worth it |
| You rent month to month or may move within a year | Often not worth it |
| You only want one camera you check yourself | Often not worth it |
One Thing That Shifts the Math: Insurance
Many home insurers discount premiums for a professionally monitored alarm system, and self-monitored systems rarely qualify. The discount will not cover your monitoring on its own, but it narrows the gap between a monitored system and a DIY one. Ranges by carrier, and how to claim it, are in our home security insurance discount guide.
If ADT Is Not Right for You
A DIY system with optional monitoring and no long-term contract is the honest alternative for renters and anyone likely to move. We compare the main options side by side, with sources:
- ADT vs SimpliSafe vs Ring: the two most popular DIY options.
- ADT vs Frontpoint: DIY wireless with a no-contract plan by phone.
- ADT vs Vivint: professionally installed, with longer financing-based contracts.
- ADT vs Xfinity Home: bundled with internet service.
- Home security without a subscription: what you give up with no monthly plan.
Frequently Asked Questions
Is ADT worth the money?
For many homeowners, yes: if you want professional installation, 24/7 professional monitoring with cellular backup, and plan to stay in your home for at least the length of the agreement, ADT-powered security is worth it. It is usually not worth it if you rent short-term, expect to move within a year or two, or only want a camera you check yourself. In those cases a DIY system without a long contract fits better.
How long is an ADT contract?
ADT's published residential terms describe a 36-month monitoring contract, or 24 months in California. Agreement terms can vary, so confirm the exact length in writing before you sign.
What happens if I cancel ADT early?
Under ADT's published residential terms, if you cancel a 36-month monitoring contract early, ADT may charge 75% of the monthly service charges remaining in the initial term. For example, cancelling with 12 months left means paying up to 75% of those 12 months of monitoring charges. Ask for the exact calculation in writing before you sign.
Does ADT have a money-back guarantee?
Yes, with conditions. ADT's terms describe a six-month money-back guarantee that applies only after ADT has made attempts to resolve a system-related issue and has not been able to resolve it within the first six months after activation. It is not a guarantee you can use simply because you changed your mind.
Is ADT better than SimpliSafe or Ring?
It depends on what you want. ADT-powered systems are built around professional installation and 24/7 professional monitoring. SimpliSafe and Ring are DIY systems you install yourself, with optional professional monitoring and no long-term contract. If you want hands-off protection, ADT-powered fits better. If you want low commitment and are comfortable with DIY, SimpliSafe or Ring may fit better.
Can ADT lower my home insurance?
Often, yes. Many home insurers offer a discount for a professionally monitored alarm system, while self-monitored systems rarely qualify. The amount varies by carrier and policy, so ask your insurer what documentation it needs, usually a monitoring certificate.
