Its sibling can already control your lock. So it only makes sense to let the August Doorbell Cam see who's at the door. Like the aforementioned lock, the cam was designed by Yves Behar, and integrates a one-way, 140-degree HD video camera, speaker, mic, and motion sensors into a single stylish plate. The system lets you see who's been at your door, even if they don't ring the bell, communicate via audio, and even buzz visitors, all from your phone, even if you're not at home. As an added bonus, the unit also acts as a Wi-Fi relay for the Smart Lock, letting you lock and unlock your door from anywhere.
