Most smoke detectors tell you a fire has already started. The Ting sensor works to prevent one from ever beginning. It’s a plug-in monitor and subscription service that listens for the unique electrical signatures of dangerous faults in your home’s wiring.

The sensor analyzes your home’s power 24/7, hunting for tiny arcs and other anomalies. If it detects a potential hazard, you get a notification through the app. More importantly, the Ting Fire Safety Team calls you to explain the finding and recommend a next step. The included $1,000 repair credit helps address verified issues. It’s a proactive layer of protection that traditional alarms can’t offer.

The service requires a $49 annual fee after the first year. It also can’t catch every possible electrical fault, but the data behind its ~80% prevention rate is compelling. For peace of mind that goes beyond an alarm, it’s a uniquely modern approach to home safety.
