About ADT

ADT has been protecting homes since 1874 — longer than almost any company in any industry, let alone home security. With over 6 million customers across the United States, ADT is the largest home security provider in the country. That scale brings advantages: nationwide coverage, massive monitoring infrastructure, and near-universal recognition from insurance companies.

In recent years, ADT has modernized significantly. The 2022 partnership with Google produced ADT+ with Google, integrating Nest cameras, speakers, and displays into ADT’s monitoring ecosystem. They also launched ADT Self Setup — a DIY product line competing directly with Ring and SimpliSafe. The company that defined professional security is now playing in the DIY space too.

The question isn’t whether ADT provides good security — it does. The question is whether the professional approach justifies the premium over increasingly capable DIY alternatives. For a head-to-head breakdown, see our ADT vs SimpliSafe comparison.


ADT Equipment and Packages

ADT Self Setup (Starter)

ADT’s DIY option competes with Ring and SimpliSafe. You order equipment online, install it yourself with adhesive mounts, and activate monitoring through the ADT app.

Includes: Wireless hub, door/window sensors, motion detector, keypad Starting price: ~$200 for equipment Monitoring: $19.99/month (no contract) Installation: DIY, ~20 minutes

The Self Setup line is simpler than ADT’s professional packages — fewer sensor types, smaller equipment catalog, and no professional installation option. But it brings ADT’s monitoring to a lower price point without a contract.

ADT Smart Home (Mid-Tier)

The core professionally installed package. A technician assesses your home, installs a touchscreen command panel, door/window sensors, motion detectors, and a key fob. Smart home control is included — lights, locks, and thermostat management through the ADT app.

Equipment: Touchscreen panel, sensors, motion detectors, key fob, smart home devices Monitoring: $28.99/month Contract: 36 months Installation: Professional (2-4 hours, included)

ADT Complete (Premium with Cameras)

Everything in Smart Home plus indoor and outdoor cameras with video surveillance. The monitoring center can view camera feeds during alarm events for faster verification and response. This is ADT at its most comprehensive.

Equipment: Everything in Smart Home + indoor/outdoor cameras, video doorbell Monitoring: $44.99-59.99/month (depending on camera count) Contract: 36 months Installation: Professional (3-5 hours, included)


ADT Monitoring and Response

24/7 Professional Monitoring

ADT operates 9 interconnected monitoring centers across the United States — all UL-listed, which is the highest industry certification. UL listing requires annual audits, backup power systems, redundant communication paths, and trained operators.

When an alarm triggers:

  1. Signal reaches ADT’s monitoring center in seconds
  2. Operator reviews the alarm type and account information
  3. Operator calls the homeowner for verification
  4. If the alarm is verified (or the homeowner doesn’t respond), emergency services are dispatched
  5. Total time from alarm to dispatch: typically under 60 seconds after verification

Response Time Testing

In our testing, ADT’s monitoring center contacted us within 30 seconds of an alarm trigger on every test. Dispatch was initiated within 90 seconds on verified alarms. These times are consistent with ADT’s published standards and our previous testing.

For comparison, Ring’s third-party monitoring centers contacted us within 45-60 seconds — still fast, but ADT’s in-house infrastructure is marginally quicker.

ADT App and Self-Monitoring Features

The ADT app provides real-time alerts, camera feeds, arm/disarm control, smart home device management, and alarm history. The app has improved significantly with the Google partnership — the interface is cleaner and more responsive than the pre-Google version.

Self-monitoring is available on Self Setup plans (push notifications and app control without professional monitoring). Traditional ADT plans include app access alongside professional monitoring.

ADT Guard (On-Demand Guard Dispatch)

ADT Guard is a premium service available in select markets that dispatches a private security guard to your home during an alarm event. The guard arrives within minutes to assess the situation, check the property, and provide a report. It’s a meaningful differentiator — no DIY system offers anything comparable.

Our Verdict

ADT delivers what it promises: professional, reliable, comprehensive home security backed by 150 years of experience and the best monitoring infrastructure in the industry. The Google partnership has modernized the platform without sacrificing the professional-grade foundation.

The cost is the deciding factor. Over three years, ADT’s professionally installed plans cost $1,000-2,000 in monitoring alone — plus any equipment fees. Ring delivers comparable protection for under $1,000 total. ADT’s premium buys professional installation, stronger insurance recognition, environmental monitoring, and the peace of mind that comes from the most established name in the business.

If those things matter to you — and for many homeowners they do — ADT is worth the investment. If you’re comfortable with DIY and cost-conscious, look at Ring or SimpliSafe first. For a detailed side-by-side breakdown, read our SimpliSafe vs ADT comparison.

Frequently Asked Questions

How much does ADT cost per month?

ADT monitoring starts at $28.99/month for the Smart Home package (alarm + smart home control). The ADT Complete package with cameras and video surveillance costs $44.99-59.99/month. ADT Self Setup monitoring is $19.99/month. Equipment costs vary — professional installation packages may include equipment or charge separately depending on the promotion.

Can I cancel ADT early?

You can cancel ADT at any time, but early termination fees apply on contract plans. The typical fee is 75% of the remaining monthly charges on your contract. On a 36-month contract at $45/month with 24 months remaining, that's $810. ADT Self Setup plans have no contract and can be cancelled anytime without penalty.

Does ADT work with Alexa or Google Home?

Yes, ADT works with both. The ADT+ with Google partnership provides deep Google Home and Nest integration — Google Nest cameras, speakers, and displays work natively with ADT monitoring. ADT also supports Alexa voice commands for arming/disarming and basic control. Z-Wave device support covers additional smart home products.

Is ADT better than SimpliSafe?

ADT is better for homeowners who want professional installation, maximum insurance discounts, and the most established monitoring service. SimpliSafe is better for anyone who wants lower costs, no contracts, and DIY flexibility. SimpliSafe's Fast Protect live agent feature is an innovation ADT hasn't matched. See our SimpliSafe review for the full comparison.

Does ADT own the equipment?

It depends on your plan. ADT Self Setup equipment is purchased outright — you own it. Traditional professionally installed packages may include equipment as part of the contract, meaning ADT may retain ownership until the contract ends. Clarify equipment ownership terms before signing any agreement.

Is ADT worth the price?

For homeowners who value professional installation, 24/7 expert monitoring, and maximum insurance discounts, ADT justifies its premium. The total cost over 3 years ($1,000-2,200 for monitoring alone) is significant, so weigh that against the convenience and peace of mind. If you're tech-savvy and cost-conscious, DIY alternatives like Ring ($20/mo, no contract) offer comparable security for less.
