Telio develops, installs and operates communications and media systems for correctional facilities. It installs telephones and related systems, allowing inmates to make monitored calls from communal areas or directly from their cells. Telio’s product range also includes comprehensive multimedia systems, which comprise, for example, TVs, radios and PCs with restricted internet access. In addition to the corresponding installations (cables and end devices), Telio also offers software that monitors telephone calls and handles the related billing. The software relieves prison officers of some of their responsibilities, thereby simplifying everyday life at correctional facilities. Furthermore, Telio extended its product portfolio to mobile detection and jamming solutions following the add-on acquisition of KEAS.
