Abstract

An intelligent door lock system is provided. One or more wireless bridges each including a computing device, an internet-facing radio, and a second radio, a first radio within communication range of the second radio of the wireless bridge, and a third internet-facing radio responsible for transmitting video. One or more cameras are provided. One or more Bluetooth devices or Bluetooth peripheral devices, collectively, Bluetooth devices are in communication with the one or more bridges. An intelligent door lock system in communication with the one or more bridges and the one or more Bluetooth devices. A keypad is in communication with the intelligent door lock system.

Claims

1. An intelligent door lock system, comprising:

one or more wireless bridges each including a computing device, an internet-facing radio, and a second radio, a first radio within communication range of the second radio of the wireless bridge, and a third internet-facing radio responsible for transmitting video;

one or more cameras coupled to the one or more wireless bridges;

one or more Bluetooth devices or Bluetooth peripheral devices, collectively, Bluetooth devices in communication with the one or more bridges;

the intelligent door lock system that includes a position sensor coupled to a drive shaft of a lock device, the position sensor sensing position of the drive shaft to assist in locking and unlocking a lock of the lock device, the position sensor configured to know its current position even if it has been moved since it has been turned off, the intelligent door lock system coupled to and in communication with the one or more bridges, the one or more cameras and the one or more Bluetooth devices; and

a keypad in communication with the intelligent door lock system.

2. The system of claim 1, wherein the keypad is an accessory to the intelligent door lock system.

3. The system of claim 1, wherein the keypad is sold with the intelligent door lock system.

4. The system of claim 1, wherein the keypad is retrofitted to an existing intelligent door lock system after the intelligent door lock system has been installed.

5. The system of claim 1, wherein the keypad is at an exterior of a dwelling.

6. The system of claim 1, wherein the keypad includes:

a battery, keypad, a Bluetooth chip and board.

7. The system of claim 6, wherein the keyboard includes one or more of:

LED lighting and a proximity sensor.

8. The system of claim 7, wherein the keypad provides for entering a communication that is encrypted, in order to gain access to the intelligent door lock system to lock and unlock.

9. The system of claim 6, wherein the lock operations are either manual or via a mobile application.

10. The system of claim 1, wherein communication is via BLE low energy.

11. The system of claim 1, further comprising:

a motion detection device is selected from at least one of, infrared (passive and active sensors);

optics (video and camera systems);

radio frequency energy (radar, microwave and tomographic motion detection);

sound (microphones and acoustic sensors);

vibration (triboelectric, seismic, and inertia-switch sensors); and

magnetism (magnetic sensors and magnetometers).

12. The system of claim 1, wherein the one or more bridges determines how far the person is from the dwelling.

13. The system of claim 1, wherein the one or more bridges tracks signal strength over time between the bridge and the Bluetooth device to determine if known or unknown people are at the exterior of the dwelling.

14. The system of claim 1, wherein the one or more bridges tracks signal strength over time between the bridge and the Bluetooth device when to determine if the person is approaching the dwelling.

15. The system of claim 1, wherein the one or more bridges tracks signal strength over time between the bridge and the Bluetooth device to determine if the person is entering the dwelling from the exterior.

16. The system of claim 1, wherein the one or more bridges tracks lock operations of the intelligent door lock system.

17. The system of claim 1, wherein the one or more bridges tracks door movements of the dwelling.

18. The system of claim 1, wherein the one or more bridges tracks door knocks at the dwelling.

19. The system of claim 1, wherein the one or more bridges interacts with a cloud lock access services to gather and relay data.

20. The system of claim 1, wherein the one or more bridges discovers the intelligent door lock system over Bluetooth device networking.

21. The system of claim 1, wherein the one or more bridges discovers lock devices of the intelligent door lock system by scanning a Bluetooth LE network for connected devices.

22. The system of claim 1, wherein the one or more bridges in operation obtains lock device status of the intelligent door lock system, wherein the status is one of a door being secured or unsecured.

23. The system of claim 1, wherein the one or more bridges in operation communicates lock device activity of the intelligent door lock system.

24. The system of claim 1, wherein the one or more bridges in operation communicates a dwelling door activity.

25. The system of claim 1, wherein the one or bridges are at an exterior of the dwelling.

26. The system of claim 1, wherein the one or more bridges uses detection of a Bluetooth device that is associated with a person to track signal strength between the bridge and the Bluetooth device to determine where the person is located at the exterior relative to the dwelling.
