wireless alarm systems
At night, the Nest Protect can detect movement and light levels nearby, allowing it to turn on a nightlight when you get up to visit the bathroom. As required by law, the sensors in the Nest Protect smoke alarm have a life expectancy of 10 years, so you won’t have to worry about replacing it for a decade. Unfortunately, the device warranty is only two years, unlike the 10 year warranties of the First Alert Onelink and Kidde KN COSM B RF. The Nest Protect smoke alarm is part of the company’s wider smart home strategy, which also includes thermostats, security cameras, security systems and video doorbells. You can also integrate third party devices like fans, sprinklers, lights, locks and more. They all can be controlled through the Nest app.
