ABSTRACT:
In conjunction with the dial-up public telephone system, voice quality lines carry videophone signals for monitoring a multitude of security locations from a central station. At the central station, telephonic interface apparatus is actuated by a control unit to selectively accomplish a telephonic connection with a remote location. Displays include the scene at the security location and related graphic data. During routine operation, security locations are displayed in sequence. Such operation may be interrupted either from a security location or central station in the event of an urgency. In such an event, the concerned scrutiny location is displayed for further communication involving status, camera selection, camera configuration, audio, video and so on. Incoming calls from scrutiny stations imply an urgent situation for immediate display. The called number, by dialed number identification system (DNIS) may indicate the status while the calling number identifies the location by automatic number identification (ANI) signals. Alternative signalling and code techniques afford flexible operation as with respect to various graphic and status indications available for displays.
