As for the video doorbell, it'll send your phone an alert whenever someone rings, letting you quickly pull up the app's video feed to see who's at the door and, if you like, talk to them. The lock will record video whenever it detects motion. There's no SD card slot for local storage of those clips -- Altro uploads encrypted video clips to the cloud.

With Wi-Fi, video recording, constant motion detection and the simple act of a motor turning your deadbolt, the Altro Smart Lock sounds like a pretty power-hungry device, and it's not like you can keep the thing plugged in. To that end, Altro's lock comes with two removable and rechargeable lithium-ion batteries that promise up to two months of juice. When one runs low, just swap it out for the other.
