Google's new Nest Cam and Doorbell can run on batteries

Google is refreshing its Nest lineup with three new products and a refresh for the wired indoor Nest Cam. Among the newcomers are Google's first battery-powered Nest Cam and Doorbell, as a recent leak indicated. You'll be able to install them just about anywhere around your home, and connect them to a wired power source, if you prefer. The battery life depends on how many recorded events the devices detect and factors like the temperature and settings. Google says the Doorbell's battery will run for up to six months on a single charge, while the Nest Cam can run for up to seven months before you need to juice it up.
