<p>According to the present invention, disclosed is an image access management system having a duplex network structure with a switching function for automatically switching to another network in an internal network failure. According to the present invention, the image access management system for collectively managing visitor information and image information with respect to a visitor based on a duplex network comprises: multiple image cameras; multiple visitor authentication devices; at least one access image processing device (VACU) for registration and managing log information for recording an image of the image camera and log information according to operation of the visitor authentication device, databasing image information recorded by the image camera based on an Ethernet duplex network, determining whether of a physical communication error of a communication port based on transmission and reception with respect to a packet generated in the duplex network, and performing automatic switching for network changes if a physical communication error occurs; and a central control computer for maintaining a communication session with at least one access image processing device, and ensuring a communication channel switched based on network changes if a physical communication error is detected by a random access image processing device.</p> |
