A site access control unit (100) comprising: a structure (102) defining at least one bay (104A), wherein the bay comprises a sensor arrangement (204, 208) configured for at least authentication of a user, wherein the site access control unit further comprises control apparatus (201) configured to: cause the sensor arrangement to scan the user (408, 410); obtain authentication clearance based on authentication data from the scan (408); and transmit an egress control signal (413) to a device (228, 230), for directing the user to leave the bay, when at least the authentication clearance is obtained.

A mobile sensing and payment method and system for parking fees is disclosed. The system includes an array of identity information collection modules in a parking facility. A background data processor collects mobile terminal identification information from a mobile terminal of a person entering the parking facility while the mobile terminal performs cell reselection. The data processor simultaneously senses transmission intensity of the mobile terminal using the terminal identity information collection modules. The data processor determines a location of the mobile terminal based upon the changes in the signal transmission intensity from the collection modules. The data processor generates a specific characteristic threshold for the mobile terminal to pass an entrance gate. The data processor causes the entrance gate to be opened records a specific time that the entrance gate is opened. The data processor records a specific time that the person has entered the parking facility.

Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for enhanced property access with video analytics. In some implementations, images of a first area captured by a camera are obtained. A number of persons in the first area is determined from the images. Data indicating one or more unique identifications is received. A number of persons who are authorized to access a second area are determined. Access is provided to the second area.

A method for detecting tailgating of subjects and/or objects at gates by measuring the occultation of a reference occulted by a subject and/or an object passing through the gate A time series based on the measured occultation is generated and a parameter from the generated time series is determined for characterization of the subject and/or the object passing through the gate.

An access control method for people in which the access control device (16) is assigned to an access point. Each access control device (16) has at least one antenna (1, 2, 8, 9, 10, 11), which emits beacons. Each access area (3) can only accommodate one person at a time. All antennas lie on an antenna plane. The transmitted beacons containing a unique access point ID, which positively identifies the access point and a unique antenna ID within predefined intervals. The received beacons are analyzed based on the RSSIs (Received Signal Strength Indicator) such that the distance of the mobile device (14) to the at least one antenna (1, 2, 8, 9, 10, 11) is determined. The received access point ID are transmitted to a server (15) or to the access control device (16) for analysis. Access is granted if the access authorization is valid for the access point ID.

Provided is an intelligent integrated security system, which integrates access control information with security search information at the time of entry/exit of a visitor (subject of a search) and a leaver, so as to individually and accurately extract, and store and/or manage visitors and leavers. The intelligent integrated security system comprises: a door opened by the recognition of admission information about a first visitor; a search board sensor for sensing the first visitor passing and moving through the door; an image capturing device for acquiring an entry image and facial image information about the first visitor; and an access control server, which divides the admission information, the facial image information, and the entry image by visitor to store same in an integrated information database.

An access control system for a passage device includes a first imaging device having a first field of view to an entrance area of the passage device for providing first image data, a second imaging device having a second field of view to the entrance area of the passage device for providing second image data, and a control unit for performing a facial recognition-based access control procedure for the first image data and/or for the second image data. The first imaging device is arranged to the passage device or in a vicinity of the passage device and the second imaging device is arranged to the passage device or in a vicinity of the passage device so that the second field of view differs at least partly from the first field of view. A method for access control of the passage device is also disclosed.
