- Smart detection, quick action: Google Nest Protect knows the difference between a concern and a full-on emergency and will alert you accordingly. If it detects a little bit of smoke or rising levels of CO, it gives you a heads-up. If it gets worse, it flashes red, activates the alarm, and talks to you, letting you know exactly what's going on.
- Informative, not annoying: Got an alert on your phone but turns out you simply burned the toast? No worries. You can easily hush the alarm from your phone using the Nest app, simple as that. What's more, the Steam Check feature ensures the alarm doesn't go off simply because of a hot shower.
- Convenient connectivity: This device connects with your smartphone and will notify you the moment it senses something out of the ordinary at home. It'll tell you if the alarm is sounding, batteries are running low, or a sensor is malfunctioning, giving you peace of mind while you're away from home. WiFi connection with internet access and compatible phone or tablet with the free Nest app and Bluetooth 4.0.
- Battery backup: This model Google Nest Protect connects to your home's wiring for power, and includes a battery backup for power outages.
