Google Nest Secure


The Google Nest Secure alarm system is designed around you. You can arm and disarm the alarm however you like. Use the Nest app from anywhere. Tap Google Nest Tag on Google Nest Guard – no passcode needed. Or just say, “Hey Google, set security to Away and guarding,” and the Google Assistant will arm it for you. No matter where you are, Nest Secure looks out for you. The Nest app sends reminders and alerts. Google Nest Detect can tell you two things: when a door or window opens or there’s motion in a room. And the built-in Google Assistant helps you control your home, manage tasks, and get answers powered by Google Search.*

*Mobile notifications require working internet and Wi-Fi.
