ADT

DT is a reliable home security company with more than 140 years of industry experience. They offer a range of services, including 24/7 monitoring, professional installation, and a variety of equipment options such as cameras, door and window sensors, and smart home devices.

Andrew Sinden, Cybersecurity Expert at StarLinkHow, remarks that ADT is a "reputable firm with a long history of offering trustworthy and complete security solutions." This sentiment is especially reflected in ADT's many positive customer reviews and six-month money-back guarantee—the longest full refund window on our list.

Why we chose ADT: They use smart home integrations and provide comprehensive 24/7 protection. You can even monitor your home and control your security system from anywhere in the world with their mobile app.

Our experience: The installation was seamless and quick—the technician also helped us set up the mobile app and put up a yard sign saying the house had a security system installed.
