How local triggers can overrule your digital signage flow in emergencies

A flexible digital signage platform allows you to intervene when needed. In some situations for example, it might be necessary to interrupt your standard message flow. Think of emergency situations, like a fire alarm or other triggers that make you want to send out an important message. 

The need for local triggers – a specific example

As already mentioned here, Centoview indeed makes a setup with local triggers possible. But how does it work? The easiest way to explain this is by sharing a specific client case, when we helped out a large fire brigade.

When the fire brigade control center contacted us, the firefighters only had their existing alarm system, consisting of beepers and sound alarms. Specific visual information about the type of incident they were being sent to, was absent. 

Today, after introducing Centoview, more than 60 screens show the address, type of incident and urgency level, as well as which fire stations, units and equipment are involved. The screens are located in key positions on all fire stations so that the firefighters immediately get crucial information about the incident.

The info released by the control center appears on the screens in real time and only on the screens of the fire stations where teams effectively are called out: at one specific station, several stations or all stations in event of a major incident. 

Local triggers – the technical side 

The control center uses a GIS system to organize a response. The data from this system needs to appear on the screens in real time. For this, the fire brigade has a dispatch engine in its Enterprise Architecture landscape, using the Digipolis ACPaaS solution, which processes the response data and makes it available to the relevant refer systems with the help of a data subscription system. The Centoview web socket server is subscribed to this data and processes it before delivering it to the various Centoview displays.

This specific setup enables the Centoview displays to show this info in real time. The other, less urgent screen info, is temporarily overruled. The physical screen display is determined locally for each screen by the inbuilt player. 

Because the images are made up of dynamic data, the info display may differ from screen to screen. Building all this on web socket technology makes it possible to achieve the required speed. The hardware and development by LG based on webOs offers this possibility. The result is a high performance, budget friendly and stable solution. And the sleek installation with no loose cables appeals to fans of elegant design.
