Video conversation/monitoring system having a remote monitoring function
First Claim
1. A video conversation/monitoring system comprising:
- a center station; and
at least one end station connected with said center station through an ISDN line,wherein said end station includes;
a detector which detects a presence of a person,an automatic calling unit automatically establishing a call between said center station and said end station in response to an output of said detector,a first camera which outputs a first image detected by said first camera,a second camera inputting with a second image detected by said second camera,a voice input/output unit,a display unit, anda controller which controls sending/receiving information by sending the input voice and one of output images of said first and said second cameras to said center station through the ISDN line, switching between output images of said first and second cameras to be sent to said center station in response to a switching indication from said center station, and outputting image and voice sent from said center station to said display unit and said voice input/output unit,wherein said center station has a conversation with said end station and monitors said end station by monitoring voice and image sent from said end terminal.

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.
