PURPOSE: A national disaster prevention and smart crime prevention system using bidirectional communications is provided to enable a user to accurately and quickly grasp the status of a disaster by using information obtained from multiple terminals, thereby enabling the user to establish accurate countermeasures. CONSTITUTION: Multiple terminals (1) of an information collection part (10) collect video information and display specific information. A primary server of a community center (20) stores the collected video information. A secondary server is connected to a primary communications network and stores video information transmitted from multiple community centers. A tertiary server of a superior public office (40) is connected to a secondary communications network and stores information transmitted from each district office (30). A central administrative agency (100) transmits and receives information to and from the superior public office. |
