## Abstract

A method of managing seamless access to locks with person/head detection is provided and includes receiving, at a mobile device, a signal from an access control device that includes a camera sensor. The signal includes an identifier of the access control device and a status of a region of interest of the camera sensor. It is determined that the mobile device includes a credential that is authorized to unlock the access control device. Based on the signal it is determined whether a person is in the region of interest of the camera sensor and moving towards the access control device. A request is transmitted to the access control device to unlock the access control device based at least in part on determining that a person is in the region of interest of the camera sensor and moving towards the access control device.

## Claims

### Claim 1

A method of managing seamless access to locks, the method comprising:
receiving, at a mobile device, signals from a plurality of access control devices, each access control device including a camera sensor, and each signal comprising an identifier of a sending access control device and a status of a region of interest of the camera sensor of the sending access control device;
determining that the mobile device comprises a credential that is authorized to unlock the plurality of access control devices;
determining, based on the signal, whether a person is in the region of interest of the camera sensor of one of the plurality of access control devices and moving towards the one of the plurality of access control devices; and
transmitting a request, to the one of the plurality of access control devices and not to any other of the plurality of access control devices, to unlock the one of the plurality of access control devices based on determining that a person is in the region of interest of the camera sensor of the one of the plurality of access control devices and moving towards the one of the plurality of access control devices, the request including the credential,
wherein the receiving and transmitting are via a short-range wireless communication interface that is initiated in response to the mobile device being within a transmission range of transceivers on the plurality of access control devices.

### Claim 2 (depends on 1)

The method of claim 1, wherein the short-range wireless communication interface is Bluetooth.

### Claim 3 (depends on 1)

The method of claim 1, wherein the plurality of access control devices are locks on one or more doors.

### Claim 4 (depends on 1)

The method of claim 1, wherein the mobile device is a smartphone.

### Claim 5

A system configured to manage seamless access to locks, the system comprising:
a processor; and
a memory comprising computer-executable instructions that, when executed by the processor, cause the processor to perform operations, the operations comprising:
receiving, at a mobile devices signals from a plurality of access control devices, each access control device including a camera sensor, and each signal comprising an identifier of a sending access control device and a status of a region of interest of the camera sensor of the sending access control device;
determining that the mobile device comprises a credential that is authorized to unlock the plurality of access control devices;
determining, based on the signal, whether a person is in the region of interest of the camera sensor of one of the plurality of access control devices and moving towards the one of the plurality of access control devices; and
transmitting a request, to the one of the plurality of access control devices and not to any other of the plurality of access control devices, to unlock the one of the plurality of access control devices based on determining that a person is in the region of interest of the camera sensor of the one of the plurality of access control devices and moving towards the one of the plurality of access control devices, the request including the credential,
wherein the receiving and transmitting are via a short-range wireless communication interface that is initiated in response to the mobile device being within a transmission range of transceivers on the plurality of access control devices.

### Claim 6 (depends on 5)

The system of claim 5, wherein the short-range wireless communication interface is Bluetooth.

### Claim 7 (depends on 5)

The system of claim 5, wherein the plurality of access control devices are locks on one or more doors.

### Claim 8 (depends on 5)

The system of claim 5, wherein the mobile device is a smartphone.
