Our verdict on ADT's professionally monitored security — and how to compare quotes before you commit
Who it's for: households that want hands-off 24/7 professional monitoring and optional professional installation, and don't mind a monthly fee and a contract.
This assessment is editorial and based on research into ADT's plans and terms, hands-on experience with monitored systems and customer feedback. Plans, pricing, promotions and contract terms vary by location and change often — confirm the current details, and compare a few quotes, before you sign anything.
ADT is the name most people think of when they picture professional monitoring, and the reputation is earned: its core strength is an established 24/7 monitoring network. When an alarm trips, the job of contacting you and dispatching responders is handled for you — that hands-off, always-on response is the whole point of a monitored service, and the reason it appeals to people who are frequently away or simply don't want to manage every alert themselves. Professional installation and broad nationwide coverage round out the appeal.
Where buyers need to slow down is the money and the commitment. Monitoring typically runs somewhere in the $30–$60 per month range depending on the tier and add-ons, plus an upfront installation or activation fee — and ADT has historically tied that to a multi-year agreement with early-termination terms. None of that is unusual for the category, but it means the advertised monthly number is only part of the story. The total cost over a contract, and the cancellation terms, are what actually matter.
That's exactly why we treat ADT as a "get a quote and compare" decision rather than a click-to-buy product. Pricing, promotions and equipment packages vary a lot by location, and rivals like Vivint and Brinks Home compete hard on the same households. Rather than signing with the first provider you call, it's worth putting two or three current quotes side by side — same coverage, same term — and letting them compete for your business. If you want monitored security and value a proven response network, ADT belongs on that shortlist.

A premium, professionally installed and monitored system with strong smart-home integration and slick cameras. A natural ADT rival to put on the same quote — compare the monthly cost and contract term head-to-head.

Monitoring plans generally run from about $30 to $60 per month depending on tier, equipment and whether you add video, plus an upfront installation or activation fee. Promotions, equipment packages and contract terms vary by location and change often, so the smartest move is to compare a few current quotes side by side rather than rely on a single advertised number.
ADT plans have historically involved a multi-year monitoring agreement, often around 36 months, with early-termination terms. Specifics depend on the package and any promotion you sign up under. Because contract length and cancellation terms materially affect total cost, read them carefully and compare them against other providers before committing.
Yes. The core of ADT is professional 24/7 monitoring: when an alarm trips, ADT's monitoring centers are alerted and can contact you and dispatch emergency responders. That hands-off, always-on response is the main reason people choose a monitored service over a self-monitored DIY kit where you handle every alert yourself.
Choose ADT-style professional monitoring if you want 24/7 response without managing alerts yourself, are often away, or want professional installation. Choose a DIY self-monitored kit if you want to avoid monthly fees and contracts and are comfortable responding to alerts personally. Many buyers compare both before deciding — getting a few quotes makes the trade-off concrete.
