Beeldkanaal is a narrowcasting system that organisations use to show information on display screens. From a single interface you control several screens and place messages on one or more of them at once. Channels determine which content appears where. The system is used in education, healthcare, libraries, hospitality, retail and internal communication, for example for announcements, waiting times or opening hours. According to the vendor, Beeldkanaal was developed in 2009 together with students of TU Delft and has been developed further since. The vendor presents the product as online software.
Beeldkanaal is a product of TEF Digitaal, a trade name of TEF Beheer BV in Numansdorp (the Netherlands). The company is subject to Dutch and European law; no foreign owner is known. The website does not state where data is hosted or whether a self-hosted variant exists, so ask the vendor. This matters most if the screens show personal data or internal information. Fix hosting and data-processing arrangements in writing before you start.
