Emergency Two-way Communication System
An emergency communication system (ECS) is any system (typically, computer-based) is sometimes also known as Communication system During Disasters,that is organized for the primary purpose of supporting one-way and two-way communication of emergency messages between both individuals and groups of individuals.
These systems are commonly designed to integrate the cross-communication of messages between a variety of communication technologies, forming a unified communication system intended to optimize communications during emergencies.
Communication is a major bottleneck in case of any major disaster particularly when the traditional network system already in force break down. In order to strengthen communications, it has been decided that police network (POLNET) will also be used for disaster management.
For this purpose POLNET communication facility will be extended to District Magistrates,Sub Divisional Magistrates as well as the Control Rooms.
An emergency notification system refers to a collection of methods that facilitate the one-way dissemination or broadcast of messages to one or many groups of people with the details of an occurring or pending emergency situation.
Mass automated dialing services such as Reverse 911, and common siren systems that are used to alert for tornadoes, tsunami, air-raid, etc., are examples of emergency notification systems.
Emergency communication systems often provide or integrate those same notification services but will also include two-way communications typically to facilitate communications between emergency communications staff, affected people and first responders in the field.
Another distinguishing attribute of the term "communication" may be that it implies the ability to provide detailed and meaningful information about an evolving emergency and actions that might be taken; whereas "notification" denotes a relatively more simplistic one-time conveyance of the existence and general nature of an emergency(such as Emergency Rescue Location).
