Abstract

An intelligent door lock system is configured to be in communication with a mobile device. The intelligent door lock system includes a drive shaft of a lock device for a door. A circuit is coupled to an engine with a memory. A device is provided that converts energy into mechanical energy and is coupled to the drive shaft. The intelligent door lock system is configured to be in communication with a mobile device that includes a vibration/tapping sensing device. The vibration/tapping sensing device is configured to lock or unlock the door in response to knocking or tapping at the mobile device.
