Access control system and method to distinguish between tailgate and piggyback
Access control system and method to distinguish between tailgate and piggyback. The method includes receiving, from a camera positioned at an access point, one or more images of a first person at the access point and determining based on credential information whether the first person is authorized to enter through the access point. In response to determining that the first person is authorized to enter through the access point, the method includes determining, based on a consent-to-follow gesture of the first person detected in the one or more images, a number of guests of the first person requested to enter through the access point. The method also includes determining, based on the one or more images, a number of persons entering through the access point and generating an alert indicating unauthorized entry when the number of persons is greater than the number of guests.
1. An access control system comprising:
a camera configured to be positioned at an access point; a feedback mechanism; and
an electronic processor coupled to the camera and the feedback mechanism, the electronic processor configured to
receive, from the camera, one or more images of a first person at the access point;
determine based on credential information whether the first person is authorized to enter through the access point;
in response to determining that the first person is authorized to enter through the access point, determine, based on an unprompted consent-to-follow gesture of the first person detected in the one or more images, a number of guests of the first person requested to enter through the access point;
determine, based on the one or more images, a number of persons entering through the access point;
provide, using the feedback mechanism, a feedback indicating the number of guests determined based on the consent-to-follow gesture; and
generate an alert indicating unauthorized entry when the number of persons is greater than the number of guests.
2. The access control system of claim 1 , wherein the access point includes a barrier and the electronic processor is further configured to
control the barrier to open the access point when the number of persons is less than or equal to the number of guests.
3. The access control system of claim 1 , wherein the electronic processor is further configured to
determine a number of allowed guests for the first person; and
generate a second alert indicating excess guests when the number of guests is greater than the number of allowed guests.
4. The access control system of claim 1 , further comprising:
an access control sensor configured to receive the credential information from the first person.
5. The access control system of claim 1 , wherein the electronic processor is further configured to
determine the credential information based on performing facial recognition analysis on the one or more images.
6. The access control system of claim 1 , further comprising a biometric sensor configured to capture biometric information of the first person, wherein the electronic processor is further configured to determine the credential information based on the biometric information of the first person.
7. The access control system of claim 1 , wherein the consent-to-follow gesture is a raised hand indicating the number of guests with fingers of the raised hand.
8. A method for providing access control comprising:
receiving, from a camera positioned at an access point, one or more images of a first person at the access point;
determining, using an electronic processor, based on credential information whether the first person is authorized to enter through the access point;
in response to determining that the first person is authorized to enter through the access point, determining, using the electronic processor based on an unprompted consent-to-follow gesture of the first person detected in the one or more images, a number of guests of the first person requested to enter through the access point;
determining, using the electronic processor based on the one or more images, a number of persons entering through the access point;
providing, using a feedback mechanism, a feedback indicating the number of guests determined based on the consent-to-follow gesture; and
generating, using the electronic processor, an alert indicating unauthorized entry when the number of persons is greater than the number of guests.
9. The method of claim 8 , further comprising:
controlling a barrier of the access point to open the access point when the number of persons is less than or equal to the number of guests.
10. The method of claim 8 , further comprising:
determining a number of allowed guests for the first person; and
generating a second alert indicating excess guests when the number of guests is greater than the number of allowed guests.
11. The method of claim 8 , further comprising:
determining the credential information based on performing facial recognition analysis on the one or more images.
12. The method of claim 8 , further comprising:
capturing, using a biometric sensor, biometric information of the first person; and
determining the credential information based on the biometric information of the first person.
13. The method of claim 8 , wherein the consent-to-follow gesture is a raised hand indicating the number of guests with fingers of the raised hand.
