Nest Protect Smoke & Carbon Monoxide Alarm, Battery (2nd gen)

• Know from anywhere. Connect Nest Protect to Wi-Fi and it will send an alert to your phone if the alarm goes off or the batteries run low.
• Tells you what and where. It speaks up to tell you if there’s smoke or CO and where the problem is, so you know what to do.
• App Silence. Nest Protect is the first alarm you can hush from your phone. Simply walk to the Nest Protect that noticed the problem and open the Nest app.
• Split-Spectrum Sensor. In an emergency, seconds count. Nest Protect uses two wavelengths of light to look for both fast and slow burning fires.
• Heads-Up. Get a friendly voice alert so you can handle burning toast before it becomes a burning toaster.
• 10-year carbon monoxide sensor. Carbon monoxide is odorless, invisible and deadly. When there’s CO, Nest Protect tells you where it’s hiding.

• 24/7 live video: 130° wide-angle view and all-glass lens let you look after home in crisp 1080p HD, day and night.
• Alerts and snapshots: When Nest Cam Outdoor detects activity, it can send a phone alert or email with a photo of the event.
• Rain or shine: Weatherproof camera, cable and adapter, so you can leave it out in the rain.
• Talk & Listen: Nest Cam has a built-in speaker and microphone, and lets you talk and listen through the app. So you can tell someone you’re paying attention or ask the mailman to leave the package at the door.
• Simple DIY installation: Just plug it into an outdoor outlet, mount the camera and go. You can even stick it to a magnetic surface — no drilling necessary.
• Comes with a free Nest Aware trial: Get intelligent alerts and continuous cloud recording. Create Activity Zones for more precise alerts. Make and share custom clips or timelapses.
