Vidsys

A vidsys is a terran device used for long distance communication between star systems. By 2505, they had been in use long enough for some models to be rendered out of date.

The visdys has a screen and a light for indication of incoming calls, flashing red when one is recieved. Messages can be sent and viewed later or a two-way connection can be established with communication in real-time. At least some locations (e.g. Umoja) have signal origin codes that are given before a connection is established.
