Access control architecture includes the data communication protocol to interface hardware with the software application, as well as the cable network to facilitate the data transmission. Of the two architectures – central and distributed – each has distinct advantages and disadvantages. It is important to understand these differences when implementing an access control system in your facility.
Centralized architecture means that the control panels, associated power supplies, input, output and reader control modules for each access device are located in a central location. Distributed architecture requires the associated power supplies, input, output and reader control modules be installed in close proximity to the access device. Assuming components are of equal quality, either system will provide the same performance capability and reliability.
