Description: SARA’s eMessenger Mobile is an advanced alerting capability of Status Solutions’ Situational Awareness and Response Assistant (SARA), an automated alerting engine that provides integrated alarm monitoring, alerting/mass notification and reporting. SARA’s eMessenger Mobile turns Apple iPhone and iPad devices into mobile command and control centers for emergency alerting and response management. All life safety, security and environmental controls within a facility can be integrated with SARA for a single point of alarm management and therefore complete situational awareness. And with situational awareness comes the ability to deliver information about potential threats in real time to virtually any communication device – especially mobile ones equipped with SARA’s eMessenger Mobile – for faster, more efficient response, especially in an emergency. Organizations can retire obsolete communication technologies, such as pagers, and expand their use of mobile devices for greater flexibility and situational awareness in the palms of users’ hands. Responders then can deal with an unfolding event more quickly, initiate alerts and associated response plans more effectively, and escalate/notify others as necessary – all from one interface. Therefore, SARA’s eMessenger Mobile is critical to and unique in risk management because it: +Turns mobile devices into command and control centers with intuitive dashboards for situational awareness and response management +Delivers color-coded alerts from disparate alarm systems across a single facility, multi-building campus or large enterprise +Allows users to receive and initiate detailed alerts, including the nature of an alarm plus location data +Escalates alerting and response management by enabling key individuals or select groups of responders to be notified in a single touch +Provides approximate location data so clinicians and staff can locate an alarm source more quickly Command and control on the go and the ability to read, hear, see, do and then analyze information for real-time situational awareness is what SARA’s eMessenger Mobile makes possible for any organization.

The MAGE app provides dynamic capabilities for mobile situational awareness. Originally developed to support first responders deploying in the event of natural disasters, the MAGE app on your mobile device allows you to create geotagged field reports and observations that contain media such as photos, videos and voice recordings and share them instantly with other members of your team. Using the GPS in your mobile device, MAGE can record user locations in real time. Your locations can be automatically shared only with the other members of your team. The app remains functional if your mobile device loses its network connection and will upload its local content when a connection is reestablished. Geospatial data layers, including map tiles and vector data, can be stored on your mobile device and are available at all times. When disconnected from the network, MAGE will use local data layers to continue to provide relevant geospatial information to teammates. MAGE is customizable and can be tailored to your team's situation. The National Geospatial-Intelligence Agency is releasing this application to the general public to increase the impact of government investments in unclassified mobile initiatives. MAGE is not hosted or managed by NGA, in order to use it you will need to get access to your agency or managing entities server. Note: Continued use of GPS running in the background can dramatically decrease battery life.
