ADT is the name most people picture first when they think of professional home security monitoring, and independent testing backs up part of that reputation — two of the largest security review publications both score ADT above 9 out of 10 for reliability and feature depth. It’s also not without real friction: a contract structure that can cost 75% of what’s left owed if you cancel early, a control panel with no touchscreen unless you pay for one, and a substantial public Better Business Bureau complaint history despite an A rating. This guide covers what ADT actually includes at each tier, what installation and cancellation really look like, and the honest limitations worth knowing before you sign a contract.

Quick Answer
ADT is a professional-install, contract-based home security service — not something you buy outright on Amazon the way a DIY brand like SimpliSafe works. Equipment is sold in packaged tiers, monitoring runs across three main plans (Secure, Smart, Complete), and Google Nest camera integration is a genuine differentiator for households already inside the Google Home ecosystem. The single biggest thing to know going in: canceling before your contract term ends costs 75% of what’s left owed on equipment and monitoring combined — that binding structure, more than any individual feature, is what separates ADT from DIY competitors.
What ADT Actually Provides
The base station itself is a communications hub rather than a display — there’s no touchscreen included standard, just a status light and a proximity sensor, with cellular backup for when Wi-Fi or landline service goes down. Around that hub, ADT builds out a genuinely broad sensor lineup: standard and premium shock/vibration door and window sensors, pet-immune motion detectors (rated for pets up to 85 lbs), glass-break sensors with a 25-foot adjustable-sensitivity range, interconnected tamper-proof smoke and carbon monoxide detectors, and water and temperature sensors.
Cameras are where ADT’s current lineup stands apart from most competitors: rather than building its own camera hardware, ADT integrates directly with six Google Nest models — a battery Nest Cam, a wired indoor Nest Cam, a wired outdoor Nest Cam, Nest Cam with Floodlight, and both battery and wired Nest Doorbells. The top monitoring tier adds Trusted Neighbor, a facial-recognition feature that grants trusted guests entry without a code.

Equipment ships as named packages rather than a single kit — independent testers have been sent bundles ranging from a basic starter package up through a full-home bundle that combines outdoor cameras, a video doorbell, and smart-lock integration. Current package and monitoring pricing changes often enough, and varies enough by region and promotion, that we’re not hardcoding exact figures here; ADT’s own site (adt.com) lists current packages directly, and the independent testing writeups cited throughout this guide include their own pricing snapshots as of publishing. ADT also offers 0% APR financing on larger equipment purchases, spread over as long as 60 months, tied to a contract for the financing term.
Monitoring Plans: What Each Tier Actually Adds
ADT’s monitoring runs across three named tiers, and the tier you pick determines which features you actually get access to:
| Tier | What It Adds |
|---|
| Secure | Core intrusion, fire, and emergency monitoring with cellular backup and 24/7 professional dispatch through one of six redundant monitoring centers |
| Smart | Everything in Secure, plus broader smart-home device integration and automation (lights, locks, thermostats) |
| Complete | Everything in Smart, plus Nest Aware, video verification, cloud clip storage, and the Trusted Neighbor facial-recognition feature |
A meaningful catch sits inside that table: video support and cloud clip storage are only included on the top Complete tier. If camera footage matters to you, budget for the most expensive plan from the start rather than assuming a mid-tier plan covers it. Monitoring response has tested fast across the board — text alerts in roughly 5–10 seconds and call alerts in 30–45 seconds in one independent test, among the fastest of the major brands compared.
Installation: What Actually Happens
Professional installation is mandatory for ADT’s core Pro Install system — self-monitoring and self-installation aren’t offered on this line at all. Scheduling a visit reportedly takes about 15 minutes over the phone, with a technician typically arriving within two days, and the on-site visit itself usually runs under two hours once it starts. A separate independent test described the fuller process — from initial consultation to a completed, trained-in installation — as effectively two touchpoints rather than one visit, so treat it as a scheduled service engagement rather than something you can do same-day on a whim. The technician walks the home to assess entry points before placing equipment and provides on-site training on the app and any automations.
If you’d rather skip the scheduled visit entirely, ADT does sell a genuinely self-install DIY line under the same brand — ADT Blu, covered later in this guide — but it’s a distinct product from the professionally-installed system this section describes, with a smaller sensor and camera lineup.
The Number That Matters Most Before You Sign
During Your Contract vs. After It Ends
75%
Cancel during your contract term, and you owe 75% of whatever’s left on both equipment and monitoring combined
30 Days
Cancel after your term ends — the contract auto-converts to month-to-month, and 30 days’ written notice cancels it with no penalty
Standard contracts run 36 months (24 months in California), with financed equipment extending that up to 60 months. Real exceptions to the early-termination fee exist: objecting in writing to a rate increase within a 30-day window, moving to a location ADT doesn’t service, and active-duty military reassignment.
The Honest Limitations
ADT’s testing scores are genuinely high, but that doesn’t mean the experience is friction-free. Here’s what independent reviewers and ADT’s own complaint history actually show:
- No touchscreen control panel included standard. The base hub is a status-light-and-hub device; full control runs through the ADT+ mobile app unless you pay extra for a touchscreen keypad.
- Video and cloud storage are locked to the most expensive plan. There’s no way to get camera clip access on a mid-tier plan.
- Local camera storage is minimal. Cameras retain only about three hours of local buffer during an internet outage, with no standing local-storage option — footage otherwise lives in the cloud, gated behind Complete.
- No 4K camera option exists in the current lineup, even on the top monitoring tier.
- Complaint volume is real and documented. ADT is BBB-accredited with an A rating, but its public profile also shows substantial complaint volume. The total changes continuously as new complaints are filed and older cases move outside BBB’s reporting window, so check the current profile rather than relying on a fixed count. Service, repair, order, contract, and cancellation concerns all appear in the complaint record.
- Some complainants report early-termination charges well above simple monthly math would suggest — from several hundred dollars up past $1,000 — once outstanding equipment costs are folded into the 75% calculation. Ask for the exact payoff figure in writing before signing, not after you’ve decided to leave.
Who This Is For
ADT is a good fit if:
- ✅ You want professional monitoring with a long track record and multiple redundant monitoring centers
- ✅ You’re already invested in Google Nest cameras or Nest Aware and want native integration
- ✅ You’d rather have a technician assess your home and install everything than do it yourself
- ✅ Fast alarm response speed matters more to you than monthly cost
ADT vs. the DIY Alternatives
ADT’s core tradeoff is a longer professional-monitoring track record and full-service installation, in exchange for contract commitment and the highest early-exit cost of any brand this site has reviewed. DIY brands trade that reputation and hands-off installation back for month-to-month flexibility and self-install setup, usually at a lower entry cost. If you’re deciding between full-service and DIY in the abstract rather than specifically weighing ADT, our DIY home alarm systems roundup compares no-contract kits from other brands side by side. If you specifically want ADT weighed side by side against SimpliSafe and Vivint on contract length, cost structure, and cancellation terms, see our full ADT vs. SimpliSafe vs. Vivint comparison.
Prefer DIY? ADT Blu Is ADT’s Self-Install Line

ADT itself now sells a genuinely separate self-install product line — ADT Blu — through both Amazon and adt.com directly. It is not the same system reviewed above: no mandatory technician visit, no long contract, and a smaller sensor and camera lineup than the full Pro Install system. The Security Starter Kit covers the basics — a base hub with cellular backup, door/window sensors, a pet-friendly motion sensor, plus a yard sign and window stickers for visible deterrence — guided through self-adhesive, app-based setup with no long-term contract required.
- Includes: security base with cellular backup, door/window sensors, pet-friendly motion sensor, yard sign, window stickers
- Install: self-adhesive, app-guided, no technician visit required
- Best for: households who want the ADT name without the Pro Install contract
Honest note: this DIY line is genuinely newer than the Pro Install business and currently carries a much smaller Amazon review base than long-established DIY competitors — worth knowing going in, even though the hardware is backed by the same company as the professional system reviewed above. Pricing and ratings shown reflect current Amazon listings as of publishing; check the listing itself for today’s numbers.
Final Recommendation
ADT earns its reputation in the categories that are hardest to fake: fast monitoring response, a long operating history, and (through Google Nest) a genuinely current camera lineup. What it doesn’t offer is flexibility — you’re signing a multi-year contract for the Pro Install system, video features are locked behind the priciest plan, and the exit cost if your circumstances change is real and well-documented in ADT’s own BBB complaint history. If a technician-installed system with a strong monitoring track record is what you’re after and you’re comfortable with a contract, ADT is a defensible pick. If contract flexibility matters more than installation service, weigh it directly against the DIY options in our DIY home alarm systems guide before signing anything.
FAQ
Does ADT require a long-term contract?
For the professionally-installed Pro Install system, yes. Standard contracts run 36 months (24 months in California), and equipment financing can extend the commitment up to 60 months. After the initial term, the contract automatically converts to month-to-month, cancelable with 30 days’ written notice and no penalty.
How much does it cost to cancel ADT early?
Canceling before your contract term ends costs 75% of what’s left owed on both equipment and monitoring combined, due in full on the termination date. Real exceptions exist for a written rate-increase objection within 30 days, moving somewhere ADT doesn’t service, and active-duty military reassignment.
Can I self-monitor ADT without paying a monthly fee?
Not on the core Pro Install system — self-monitoring isn’t offered there at all, and professional monitoring is mandatory. ADT’s separate self-install line, ADT Blu, does support flexible, non-contract setups, but it’s a distinct, smaller product from the system this review is centered on.
Does ADT work with Google Nest and Google Home?
Yes, and it’s a genuine differentiator — ADT integrates directly with six current Google Nest camera and doorbell models, and its top monitoring tier includes Nest Aware along with a facial-recognition Trusted Neighbor feature.
Is ADT worth it compared to DIY brands?
It depends on what you’re optimizing for. ADT wins on professional installation, monitoring-center redundancy, and Google Nest integration; DIY brands win on contract flexibility, lower entry cost, and self-install control. See our DIY home alarm systems guide for how the no-contract alternatives compare directly.
