Smart Lock

A smart lock on a door is more than a simple lock; it is a system that includes a user interface, position sensors, battery, processor, and DC motor that moves the latch. Smart locks use a wireless interface, allowing local control through a smartphone and remote control via a PC connected to a communications network.
