interTRAX for Emergency Management offers the tools needed for resource management and interagency interoperability. Emergency managers are responsible for the deployment of responders and resources to the site. At the same time you must track those leaving the scene, including evacuees and patients. You need to control access to the site, handling both pre-credentialed responders and individuals who need access but have yet to be credentialed. You need a way to interact with agencies using FIPS201/FRAC cards. All of this activity and data requires monitoring off-scene, and needs to be shared with others including federal and state agencies, hospitals, and public health. The interTRAX Suite for Emergency Management is a complete solution offering total resource visibility.
