Nest unveils security camera, second-gen Protect smoke detector and updated app

The Cam is based heavily on technology gained Nest's acquisition of Dropcam. Like the Dropcam Pro, Cam shoots video — now up to 1080p — with a wide 130-degree field of view and includes night vision support, while a microphone and speaker allow users to both talk and listen through the device. With Nest Aware (formerly Cloud Recording) subscribers can access recorded video online up to 10 or 30 days later.

Through the Nest mobile app, Cam owners can check video feeds, send voice clips and receive notifications whenever motion is detected.

The Protect has been upgraded with a new sensor that monitors two different light wavelengths, which Nest claims is better for detecting different kinds of smoke and hence both fast- and slow-burning fires. An improved smoke chamber, meanwhile, is intended to screen out debris and reduce false alarms.

Via the Nest app, owners of the new Protect can silence an alarm or run a safety checkup. Other product changes include a 10-year expected lifespan, thanks to a better carbon monoxide sensor, and the optional Nest Safety Rewards program, which can be used to get cheaper home insurance from Liberty Mutual and American Family at the expense of sharing Protect data.

The updated Nest app has been redesigned with a simpler interface, and monitors Cam, Dropcam, Protect, and Thermostat data. Thermostat users can now see indoor humidity and outside temperature, and tap an icon to let the device know if they're home or away. The number of supported Thermostats has been raised from 10 to 40 with a limit of 20 per building.

A single Cam is $199, while a Protect is $99. A Nest Aware subscription costs $100 a year for 10 days of video history, or $300 per year for 30 days.
