PHIL 9108–9112 depicted the Aiphone® Universal Video Entry System, a prototypical video phone designed to allow residents to identify visitors before granting entrance, and to allow them to monitor communication without having to go to the master station should moving be slow, difficult, or undesirable at that time. The system's features include visual, tactile, and audible feedback offering an unusually high degree of redundancy in conveying information, while its Video Entry System offers security and convenience to all users, especially those who live alone. Here, a woman was using the Aiphone® to communicate with a caller.
By moving the cursor key, then pushing the Auto-Answer button, a resident may select a message from the monitor’s prerecorded message group to respond to visitors. This conveys the synthesized voice message to the visitor, a function extremely useful for someone who has difficulty speaking. If not at home, the system can video-record a visitor's image and voice, and later deliver a pre-selected audio message.
