Abstract

캠코더 및 감시용 카메라에 있어서, 화상은 줌을 이용하여 먼곳의 촬영이 가능하나 음성신호는 그 특성상 먼곳에서 수신이 미약하여 제대로 녹음시킬 수 없는 문제점이 있는 것으로 촬영하고자 하는 장소의 일정위치에 음성신호를 무선으로 송신하는 송신기(60)(70)(80)를 설치하고 상기 송신기(60)(70)(80)의 송신 음성신호를 세트에서 송신기 선택스위치(10)의 선택입력에 의하여 디멀티플렉서(50)에서 선택되게 하므로써 촬영자가 원하는 장소의 음성신호를 마음대로 선택하여 확실히 녹음시킬수 있다.In camcorders and surveillance cameras, images can be taken from a distance using zoom, but voice signals cannot be properly recorded due to their poor reception from a distance. A transmitter 60, 70, 80 for wireless transmission of the transmitter, and the demultiplexer 50 by the selection input of the transmitter selection switch 10 from the transmitter 60, 70, 80. ), You can select the voice signal of the place you want and record it clearly.
