Abstract

본 발명은 비디오라인진단기능을 구비한 도어비젼에 관한 것으로, 특히 도어비젼의 아웃도어장치로부터의 비디어신호중 동기신호를 검출하여 아웃도어장치가 정상동자가는지의 여부를 판별하고, 그 판별결과를 인도어장치에 부착된 표시부로 표시함으로써, 도어비젼에서 아웃도어장치내 카메라에서 인도어장치내 모니터로 비디오신호가 제대로 전송되고 있는지를 용이하게 진단가능토록한 비디오라인진단기능을 구비한 도어비젼에 관한 것이다.The present invention relates to a door vision having a video line diagnosis function. In particular, a synchronization signal among video signals from an outdoor device of a door vision is detected to determine whether the outdoor device is a normal pupil, and the determination result is determined. The present invention relates to a door vision device having a video line diagnosis function that makes it easy to diagnose whether a video signal is properly transmitted from a door vision camera to an indoor device monitor by displaying the display unit attached to the indoor device. .

본 발명은 도어비젼의 아웃도어장치로부터 비디어신호중 동기신호를 검출하여 아웃도어장치가 정상동작하는지의 여부를 판별하고, 그 판별결과를 인도어장치에부착된 표시부로 표시하므로써, 도어비젼에서 아웃도어장치내 카메라에서 인도어장치내 모니터로의 비디오라인이 자연적 또는 인위적인 요인으로 발생되는 이상을 용이하게 진단가능하게 되는 것이다.The present invention detects a synchronous signal among video signals from an outdoor device of a door vision to determine whether the outdoor device operates normally, and displays the result of the determination on the display unit attached to the indoor device. The video line from the in-device camera to the monitor in the indoor device can easily diagnose the abnormality caused by natural or artificial factors.
