Abstract
A video conversation/monitoring system having a remote monitoring function includes a center station and multiple end stations linked through the ISDN network. The center station includes a video conversation/monitoring circuit, video input device, video output device, audio input device, audio output device, system controller, facsimile, and ISDN line terminating unit. Each end station includes a video conversation/monitoring circuit, system controller, first video input device, second video input device, audio input device, audio output device, calling device, first notification device, second notification device, detection device, facsimile, and ISDN line terminating unit. Based on the remote monitoring function of the video input device and the remote control function of the system controller for switching the video input device, various guidance services are accomplished in addition to the video-phonic conversation service. The integrated unit enables easy desk-top installation, the application of the ISDN network reduces the communication cost, and the provision of various state detection devices in the end stations enables image-based monitoring and state monitoring in addition to the conversation.
