Nest has reinvented the smoke alarm. Meet Nest Protect Smoke! The smartest smoke alarm you've ever seen. It is equipped with high quality sensors, tests itself and its custom algorithms can detect what's a threat from what's not - so you can enjoy a shower without being disturbed by an awful alarm.
Nest Protect is smart. It analyzes the situation, sees if there is a danger and speaks. Hence Nest Protect alerts you of potential danger before it gets out of control. And there is more. All Nest Protect work together. When one speaks, they all speak; so you can be aware of what is going on even if you are in the wrong room.
Nest Protect is convenient. No need to be in the room or even at home to know what is happening. Nest Protect is connected to your phone and sends alert to everyone in the family! And if you have the situation under control, you can just have the alarm stop directly from your phone.
