Artec has developed an e-paper display based digital signage system. The system is ethernet-connected and the displays are managed by a central management server. Display devices integrate RFID card readers for local interaction. The displays have ethernet communication interface and are powered via PoE.
The display devices contain an internal flash storage for offline operation. The pre-rendered image content is uploaded from the server to the devices embedded HTTP server over REST API. The device sends operational data to server as SNMP TRAP messages.
Devices contain a local configurable sequence engine, that handles local events. Following rules in the configuration file, the sequencer coordinates the image update in response to card scans and timeouts.
The display devices connect to a back-end centralized management server via ethernet network (DHCP, HTTP, SNMP). The server polls the device status periodically. Device RFID card scans are sent to server directly via SNMP for logging.
The server has a web interface. Over the web interface can site administrators manage the behaviour of the devices and the media files.
