We compare ADT and Nest to help you determine the better security provider for your home.

ADT and Nest are two home security providers that offer basic and advanced solutions.

Compare ADT vs. Nest

Industry Experience

Winner: ADT

ADT has been a trusted, consistent name in home security for over 140 years. While Nest has the Google brand to leverage, it partners with Brinks to provide monitoring service. While Brinks is another well-established brand name, it has gone through a number of acquisitions and spin-offs. After over a decade of being out of the residential industry, Brinks Home Security just re-launched in 2018.

Contract Flexibility

Winner: Nest

Nest is a better choice for commitment-phobes. Once you start month-to-month monitoring with Brinks, you can cancel at any time without penalty. You can even self-monitor the Nest system through the mobile app and never opt into monitoring at all. ADT requires a minimum 36-month contract with early termination fees, and there is no option to self-monitor.

Guarantees & Warranty

Winner: ADT

ADT offers a 6-month money-back guarantee if it can’t resolve concerns with equipment or service, along with a theft protection guarantee that promises up to $500 toward your home insurance deductible should a burglary occur while the system is armed. ADT’s theft protection guarantee on top of its warranty is a plus that we believe gives the provider an advantage. The Nest Secure Alarm System has a limited 1 year warranty that spans up to 3 years depending on the product.


Winner: Nest

For the latest and greatest cameras, go with Nest. As a Google-owned consumer technology company, Nest releases new products several times a year and helps to set standards for the industry. While ADT offers several camera options that definitely get the job done, they don’t always have the sleekest looks or the most cutting edge specifications.

Price & Value

Tie: ADT & Nest

ADT and Nest have neck-and-neck prices for their entry level monitored home security systems. If you purchase the ADT Traditional Package, you’ll have to pay $99 upfront plus $35.99/mo. for monitoring. ADT also requires a 36-month contract and professional installation. Installation cost varies, but $100 is a reasonable estimate. For 36 months of service, that’s $1,494.64 total. A Nest Secure Alarm System costs $1,443 for the same duration – $399 for equipment plus $29 per month for monitoring, without installation service.


Tie: ADT & Nest

We appreciate professional installation because it ensures the system is set up right and that you’re using it correctly. But it’s not for everyone: Do-it-yourself (DIY) installation saves money, avoids the hassle of scheduling an appointment, and doesn’t require a stranger in your home. ADT requires professional installation, which typically entails a fee. Nest products are designed for easy DIY installs, but if you need help you can hire a Nest Pro.

Professional monitoring starting price $35.99/mo. $19/mo.
Installation Professional DIY or Professional
Trial Period 6 months 30 days
Contract length 36 months Depends on the monitoring plan you choose
BBB rating A+ C
