Digital signage
Also known as: Digital displays
Digital signage means screens whose content is managed centrally and scheduled, instead of being maintained locally on each device.
Digital signage consists of three parts: the screen with a playback device, the software that manages content and schedules, and the network connection in between. The difference from a screen with a USB stick is central management: content is stored once and runs on all assigned devices, with fixed run times and without anyone plugging anything in on site.
In operation, reliability depends less on the screen than on its surroundings: devices need a stable connection, they must be reachable remotely to fetch content and updates, and they should return to the right state on their own after a power cut. A screen showing the setup menu in a reception area is almost always a network or operations issue, not a display issue.
On the security side, signage devices belong in their own network segment. They run permanently, are rarely updated and often stand in publicly accessible places — three properties that together do not belong in the same network as accounting and servers.
What it means in practice
At Smartenic, central management of the displays is part of what NDVDL supports — together with the network the devices use to fetch their content. In existing installations the most common finding is not a broken screen but a device without a proper network connection.
