The EZcall iServer is a wireless duress and locating system that can provide precise room-level location for alarm events. Unlike traditional RTLS systems, the iServer uses triangulation algorithms to determine the exact room an alarm was triggered in. When an alarm is received, responders are informed of who activated it and the precise location. The iServer offers scalability, reduced installation costs due to wireless mesh technology, multi-floor locating, and enhanced security for components.
