Nippon Telegraph & Telephone Corp has developed a Simple Monitor System that can send monochrome moving images over the phone company’s INS-64 ISDN network: images from video cameras mounted in 16 locations can be automatically interchanged, being sent in standard mode at a rate of one screen per second, and in high speed mode at three screens per second; the system consists of a transmitter and receiver and an operating device, all manufactured for NTT by Hitachi, and the prime use is likely to be in banks and other places where security surveillance is needed.
