n 2011, VSBO identified the requirements of an entrance-control system. During an evacuation, the facility needed to be able to track who had left the buildings, who had reported to one of the designated meeting (or muster) points and who most likely was still within the complex. The system also had to be Internet-based, so administrators could check visitors' status from anywhere within the facility or remotely. Other system requirements included the ability to issue ID tags to non-sworn staff members, as well as biometric verification for positively identifying individuals.
