Nest Labs today unveiled a new home surveillance camera and improvements to its Nest Protect smoke detector, as well as an app that will let you control all your Nest products in one place.

The new Nest Cam is very similar to the existing Nest Dropcam Pro, but marks the formal integration of Nest and Dropcam, which the company acquired last year for $555 million. "Now we've taken all the best parts of Dropcam and made them even better," Nest said today.

The Nest Cam, on sale now for $199, can sit on furniture or be affixed to a wall or metal surface and monitor your home when you're away. It connects to Wi-Fi and records 1080p HD video and supports 8x digital zoom. Night vision, meanwhile, knows the difference between sunlight and artificial light, which "can be hugely helpful if an intruder turns on a flash light, or if headlights flash across your window," Nest said.

The device allows you to speak through it via the Nest app to admonish misbehaving pets or children. Nest Cam will also alert you if it detects motion or noise in the home, but the company said it has improved its tech so it's not sending false alarms; "no more alerts from passing cars or shadows on the walls."

To review footage, Nest Cam saves up to 10 days of video (for an extra $100 per year), and you can go directly to sections with motion or sound. If you subscribe to Nest Aware with Video History for $300 per year, you can rewind footage up to 30 days and get more accurate motion alerts. If you find something noteworthy in that footage, you can make clips and timelapses.

The New Nest Protect
The Nest Protect had a tough 2014. The company was forced to temporarily halt sales when it discovered that "a unique combination of circumstances" could unintentionally activate the Wave feature, which allowed users to silence an alarm with the wave of a hand. It returned a year ago minus the Wave feature, with a discounted price.

Now it's back with a second-generation smoke and carbon monoxide detector that is "redesigned inside and out" and will last up to 10 years.

The $99 device includes what Nest calls a "Split-Spectrum Sensor" that detects whether your house is about to be engulfed by a five-alarm conflagration or if you simply overcooked dinner and now have a smoky kitchen. The Protect has a "smoke chamber" with "tiny hexagonal holes that let smoke in and keep everything else out"—no dust and bugs.

"With Nest Protect, fast detection means an earlier Heads-Up: a soft chime and voice to let you know that smoke levels are rising," Nest said. "It's an early notification you can easily hush. No panic. No noise. Just lower the heat. Open a window. Make breakfast."

To quiet an alert, open the app on your phone and press Silence. You can also test your Nest Protect from the app.

For those who want to save money on the Nest Protect, the company is teaming with insurance companies on discounts, starting with American Family and Liberty Mutual. You can either get a free Nest Protect or save 5 percent on home insurance premiums.

All Nest devices, including the Learning Thermostat, can now be controlled by the updated app for iOS, Android, and the Web. See all your devices on the home screen, watch live footage, and let your devices know if you're home or away so it can adjust thermostat and camera settings.
