A vidsys is a terran device used for long distance communication between star systems. In use by 2488,[1] by 2503[2] they had been in use long enough for some models to be rendered out of date.[3] They are quite expensive to use—twice as much as an interplanetary fone.[1]

The visdys has a screen and a light for indication of incoming calls, flashing red when one is received. Messages can be sent and viewed later[3] or a two-way connection can be established with communication in real-time.[4] At least some locations (e.g. Umoja) have signal origin codes that are given.[5]

The vidsys appears to be a somewhat resilient piece of equipment, with second-hand systems and/or battered ones still able to function (quirks aside).[3][5]
