PROBLEM TO BE SOLVED: To provide a horn speaker to a center equalizer part of which a motor-driven zoom lens attached ITV camera is assembled. SOLUTION: An ITV camera lens and an ITV camera body are contained in a horn speaker equalizer, and a lens opening is provided to the entire face of the equalizer part. Then video output and external control terminals and an AC input cable are provided to a plug. A video image imaged by a camera is outputted from the video output. Further, the horn speaker independently carries out substantial sound collection or loudspeaking operations. A supervisory system configured with the horn speaker eliminates the need for a conventional ITV camera. The horn speaker is applicable to systems capable of performing supervision by sound collection and video image. COPYRIGHT: (C)2004,JPO&NCIPI
