Nest's more secure smart home, in pictures

Nest made a splash in the smart home Wednesday with several new products, including an outdoor cam, a doorbell cam and a whole-home security system. Click through for more pics from today's Nest event. 

Nest's new security system -- called Nest Secure -- includes the Guard, the Tag and the Detect. 

The Nest Secure starter pack will cost $500 and includes a Guard, two Detects and two Tags. 

The Nest Guard is the keypad for Nest's new security system. The Guard has an 85-decibel siren, a backup battery and an LTE/3G backup, as well as arm and disarm capabilities. 

Tap your security system on and off with the Nest Tag. 

Stick this sensor to a door or window and it'll send you a push alert when it opens. The Detect also senses motion. 

We got a chance to take a closer look at the pieces of the Nest Secure system. 

You can of course control the system with your phone. 

Monitor security yourself, or pay for professional monitoring. 

Nest also introduced a doorbell cam on Wednesday called the Nest Hello. 

The cam has person recognition -- it distinguishes people from pets and objects -- as well as the more difficult facial recognition. 

The price for the Nest Hello hasn't been announced. 

Finally, Nest brought its IQ cam tech to an outdoor model. 

Complete with facial recognition capability, SuperSight, two-way talk and more, this model is supposed to bring Nest's premium IQ tech to your yard. 

The outdoor Nest Cam IQ will retail for $350. 

You'll be able to see footage from any Nest cam on the app. 

After Wednesday's event, Nest's lineup of smart home products is much more robust.
