Compare ADT and eufy across alarm coverage, professional monitoring, cameras, local storage, privacy, outages, account control, written quotes, and a 90-minute acceptance test.

ADT charges $28-45/month with a 3-year contract ($199 install + $1,008-1,620 in monitoring). eufy costs $0/month — buy a $200-400 camera kit and store footage locally, no subscription. Over 3 years: ADT runs $1,200-1,800+, eufy stays under $400. The catch: eufy has zero professional monitoring, no door/window sensors, and no police dispatch. ADT has all of that but terrible cameras. We break down when each makes sense and why Abode ($6/mo, DIY, real sensors + cameras) beats both.

Google killed the Nest Secure alarm in 2020 and never replaced it. Nest is now cameras and doorbells only — no door sensors, no motion detectors, no professional monitoring, no siren. Abode is a full security system: sensors, keypads, professional monitoring from $6/month, and the only major brand with native Apple HomeKit support. If you want actual home security (not just cameras), this comparison is straightforward. We break down what Nest can and cannot do vs Abode across monitoring, sensors, cameras, smart home, and cost.
