Data extraction and processing systems and methods for extracting security tour data collected by tour guards and stored in local security systems for delivery to a central monitoring center. Collected security tour data is periodically checked to determine if it previously has been sent to the central monitoring center, and if it hasn't then the security tour data is prepared and sent to the central monitoring center. As new data extraction routines are become available, they are automatically identified by the local security systems and downloaded. Once downloaded, the current data extraction routines are replaced with the new data extraction routine.
