Nest is getting into the smart doorbell business with Hello, a small, remote-sized device that can stream live HD video to your phone and send and receive audio. The doorbell, which Nest unveiled today at a hardware event in San Francisco, is part of a broader security push that’s building on Nest’s existing security camera business, itself part of an acquisition in 2014 of video-monitoring startup Dropcam.

The Hello doesn’t have too many bells and whistles. The device has a 160-degree field of view, so it can see packages laying on the ground or even very tall guests standing at your door. The camera itself is equipped with HDR, similar to the Nest Cam IQ models, so that it can adjust to various changes in lighting. It also has a built-in wedge so you can adjust the angle of the camera to match your doorstep setup.
