LOGIPIX System is based on a server-client architecture that is built on an SQL database, which is very similar to big IT networks and essential in case of medium size or enterprise-class systems. Using multi-tier system structure allows for clustering processes and centralizing important functions isolated from the system end points. This way crucial data are stored in a protected location in a database. The server also provides continuous and smooth system operation in case of any occurring error. It helps to restore system configuration, manages spare network video recorders if primary ones are malfunctioned and when server is mirrored, the secondary server can take over the system management in no time if needed.
