Abstract

다중영상기록장치는 복수채널의 외부신호입력원의 영상신호를 간헐적으로 기록하는 감시시스템에 있어서, 복수채널로 유입되는 영상신호의 동기신호의 유무를 검출하여 동기신호가 검출되지 않는 경우 내부동기신호를 시스템 자체내에서 공급하여 입력이 없는 채널 또는 고장난 카메라가 있더라도 다른 채널에는 영향을 미치지 않으면서 복수의 영상신호를 기록할 수 있다.The multi-image recording apparatus is a surveillance system for intermittently recording a video signal of an external signal input source of a plurality of channels. When the synchronization signal is not detected by detecting the presence or absence of a synchronization signal of a video signal flowing into the multiple channels, the internal synchronization signal is detected. It is possible to record a plurality of video signals without supplying other channels even if there is a channel without an input or a broken camera by supplying the system itself.
