An access control apparatus and method. Enrollment is conducted at a centralized server and enrollment data, such as identification data is downloaded to plural local access units at respective entrances to a restricted area. The local access units then collect data of a person upon an attempted entry in to the area and compare the data with downloaded enrollment data to determine if the person is authorized for access. If the person is authorized, an access control device is operated to open a door, gate, or the like of the entrance. The enrollment data can be biometric data and the same type or different type of biometric data can be collected at the local access units. If a different type of data is collected at the local access units and is correlated to data stored on the local access unit, data of the same type as the downloaded data is collected and compared to the downloaded data for access control. The enrollment data can be non environmentally affected data, such as fingerprint parameter data and the different type of data can be environmentally affected data, such as facial parameter data.

1. An apparatus for controlling access into an area to, comprising:a server including server memory and a server data collection device configured to collect identification data assigned to an authorized person; a local access unit located at an entrance to the area and including local memory, a local processor, a local biometric parameter sensing device, a local data collection device and an access control device; and a communication channel for downloading the identification data from the server to the local access unit; wherein said local processor is operative to compare biometric parameter data of a person proximate the entrance collected by said local biometric parameter sensing device with biometric parameter data stored in said local memory and to grant access to the area by operating said access control device if the biometric parameter data collected by said local biometric parameter sensing device and biometric parameter data stored in said local memory correspond to one another, and wherein said local processor is operative to prompt the person to enter the identification data through said local data collection device and grant access to the area by operating said access control device only when the identification data of an authorized person is entered if the biometric parameter data collected by said local biometric parameter sensing device and the biometric parameter data stored in said local memory do not correspond, and wherein said local processor is also operative to store the biometric parameter data collected by said local biometric parameter sensing device in correspondence with the identification data in said local memory when the biometric parameter data collected by said local biometric parameter sensing device and the biometric parameter data stored in said local memory do not correspond and the identification data of an authorized person is entered through said local data collection device.
