Nest has made changes across the entirety of its product line, with updates to its existing products and the launch of a new item. The new version of Nest Protect and the Nest Learning Thermostat software update are joined by the Nest Cam, a network-connected camera stemming from its acquisition of Dropcam last year, and a new program that could help homeowners acquire a Nest Protect at a lower cost or potentially for free.
