Emergency communication vs. notification




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 Cell Broadcast, Reverse 911, as well as common siren systems that are used to alert for tornadoes, tsunamis, air-raid, and other such incidents, are examples of emergency notification systems.

Emergency communication systems often provide or integrate those same notification services but will also include two-way communication—typically to facilitate communications between emergency communications staff, affected people, and first responders. 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.

Alternate and related termsedit

Since there are a collection of related systems used in diverse settings in varying ways, there are numerous terms that are used interchangeably among the entities that use or have a need for emergency communication systems. In most instances, though, these are all used to refer to the same or substantially similar concepts. For example, use of the terms “emergency communications” and “disaster communications” definitively refer to the same concept, with the only potential difference lying in the connotation or emotional meaning.

Timeliness and speed of delivery edit Emergency systems require timely and quick dissemination in order to mitigate damage or loss of life. During the Virginia Tech massacre, about two hours had passed before the first communication (an email) was sent to staff and students. By that time, the gunman had already entered and secured a building in which he was shortly to begin his attack. It wasn't until about 20 minutes after the shootings began that a loudspeaker announcement was made for people to take cover. Ease of use edit During a crisis, the people who use an ECS need to quickly and easily launch their notifications and they need to be able to do so in a way that securely provides them with confidence and an intuitive, familiar and easy-to-use interface that can be accessed from any location. An emergency communication system that's designed for non-technical users will ensure successful administration and usage; and during some life-threatening emergency situations, campu

You may improve this section, discuss the issue on the talk page, or create a new section, as appropriate. ( June 2018 ) (Learn how and when to remove this template message) With the growth of populations and the evolution of technology, the methods for communicating emergency situations have also changed, as has the definition for what might constitute an “emergency.” These methods would also very likely depend on a particular region's culture and location, as well. Early systems edit In America's formative years, common means of emergency communications may have mostly consisted of church bells being rung or messengers on horseback. Later, as technology developed, the telegraph became a nearly instant method of communicating. From there, radio communications, telephones and sirens became commonplace. After the surprise attack on Pearl Ha

Broadcast technologies

Perhaps the oldest or most basic forms of public communication are staples such as over-the-air television, sirens, and radio. More modern components (using the same concept) might include lights and Giant Voice systems. These all have one thing in common: they broadcast indiscriminately to anyone who has the means to receive the message; whether they are simply in the immediate area or require some sort of receiving device. Broadcast technologies use point-to-point communications methodology and may either require infrastructure or not. Examples of broadcast technologies requiring infrastructure might include such things as Reverse 911 and broadcast-affiliate networks. Infrastructure-independent edit Broadcast technologies that do not depend on man-made infrastructure to convey communication may be least susceptible to disruption during disasters and emergencies. Some examples of infrastructure-independent technologies are: Short-wave Radio Short-wave (or Amateur) radio is a relative
