SecuraTrac^® has created the MobileDefender^™ Model S (MD-S), an mPERS device that can be integrated into Mass Notification Systems (MNS) to create new channels of communication and enhance response potential during an emergency. Integrating an MNS with the SecuraTrac mobile safety platform enables organizations to incorporate more detail in the event of an emergency because there can be a two-way dialogue about the event. Then more specifics about what to do, where to go, how to remain safe, etc. can be built into the MNS.
