extWARN is a browser-based solution that makes broadcasting alerts and warnings to office employees and/or campus personnel fast, easy, and accurate. extWARN enables you to rapidly broadcast alerts and warnings directly to network users via UDP/IP. extWARN includes a web-based Administration Console which provides for management of all broadcast warnings/targets as well as for transmission of all alert/warning broadcasts to users via UDP/IP. extWARN also includes a Client Module that is loaded into PC's at Windows® startup or when users log into the network. This client program monitors a defined UDP port for receipt of extWARN alerts/warnings and automatically invokes a built-in client web browser to display the transmitted information. Each extWARN alert/warning can be a web page, image file, audio/video clip, or virtually any other type of file that can be displayed in a web browser. Each extWARN broadcast target consists of a min/max IP address range, plus up to five IP address inclusions/exclusions.
