Mobile device notification via access control device
An access control device and a method for operating an access control device are provided. The access control device includes a detection sensor, a communication module, and a processor. The detection sensor is configured to detect a status event (e.g., a rotation of a handle, or an insertion or closure of a keybox). The communication module is in wireless communication with a mobile device. The communication module is configured to receive an advertising signal from the mobile device. The processor is in communication with at least one of the detection sensor and the communication module. The processor is configured to determine whether a distance between the mobile device and the access control device is greater than a threshold when the detection sensor detects the status event. The processor is configured to trigger a notification when the distance is greater than the threshold.
1. An access control device comprising:
a detection sensor configured to detect a status event;
a communication module in wireless communication with a mobile device, the communication module configured to wirelessly receive an advertising signal from the mobile device;
a processor in communication with at least one of the detection sensor and the communication module, the processor configured to
responsive to detection of a status event, determine whether a distance between the mobile device and the access control device is greater than a threshold, wherein the processor is configured to
responsive to determining that the distance is greater than the threshold, trigger a notification; and
a lock actuator operatively connected to the processor, the processor configured to maintain the lock actuator in an unlocked position responsive to the distance being greater than the threshold.
2. The access control device of claim 1 , wherein the status event comprises at least one of: a rotation of a handle, and an insertion or closure of a keybox.
3. The access control device of claim 1 , wherein the processor determines the distance between the mobile device and the access control device based on a received signal strength of the advertising signal.
4. The access control device of claim 1 , wherein the mobile device comprises a MEMS sensor, the mobile device configured to transmit the advertising signal only when the MEMS sensor detects movement.
5. The access control device of claim 4 , wherein the MEMS sensor comprises at least one of: an accelerometer, an inclinometer, and a gyroscope.
6. The access control device of claim 1 , wherein the processor determines the distance between the mobile device and the access control device to be greater than the threshold when the advertising signal is not received within a time period.
7. The access control device of claim 6 , wherein the time period is less than two (2) seconds of the detection of the status event by the detection sensor.
8. The access control device of claim 1 , wherein the threshold is less than five (5) feet.
9. The access control device of claim 1 , wherein the notification comprises at least one of: an audible signal, a vibratory signal, and a visual signal.
10. The access control device of claim 9 , wherein the notification is performed by at least one of: the access control device, a room management system, the mobile device, and a wearable.
11. The access control device of claim 1 , wherein the communication module is configured to receive an access credential from at least one of: an RFID card, a FOB, a card with a magnetic stripe, and the mobile device.
12. The access control device of claim 11 , wherein the processor is configured to determine the distance between the mobile device and the access control device only if the communication module receives the access credential from the mobile device.
13. The access control device of claim 12 , wherein at least one of the access credentials and the advertising signal are transmitted to the communication module using a shortrange communication.
14. A method of operating an access control device comprising a detection sensor, a communication module, a processor, and a lock actuator, the method comprising:
detecting a status event with the detection sensor;
determining, by the processor, whether a distance between the access control device and a mobile device is greater than a threshold;
triggering a notification with the processor responsive to the distance being greater than the threshold; and
maintaining the lock actuator in an unlocked position responsive to the distance being greater than the threshold.
15. The method of claim 14 , wherein the status event comprises at least one of: a rotation of a handle, and an insertion or closure of a keybox.
16. The method of claim 14 , further comprising maintaining a lock in an unlocked position when the distance is greater than the threshold.
17. The method of claim 14 , wherein the processor determines the distance between the mobile device and the access control device based on a received signal strength of an advertising signal from the mobile device.
18. The method of claim 17 , wherein the mobile device is configured to transmit the advertising signal only when a MEMS sensor detects movement of the mobile device.
19. The method of claim 14 , wherein the processor determines the distance between the mobile device and the access control device to be greater than the threshold when an advertising signal is not received from the mobile device within a time period.
