The area-of-refuge station has the following features:
800×480 pixel display with touch interface
4-watt speaker and built-in microphone
Ethernet and 4-wire interface for power and communication
Inside the enclosure, you’ll find the mainboard and network card. On the right, you can see the 4-wire cable, which handles both power and communication. For testing purposes, the unit in the picture is powered by an external power supply. However, during regular operation, this external power source is unnecessary, as the unit is powered directly through the 4-wire cable
