Abstract

<P>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. <P>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. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a monitoring system that performs loudspeaking, sound collection, and image capturing of a subject in a visual field, and performs monitoring.
[0002]
[Prior art]
Conventionally, as shown in an example in FIG. 2, an ITV camera and a speaker are separately installed at a surveillance camera installation location.
In FIG. 2, when monitoring by loudspeaker, sound collection, and video is performed, a system is constructed by combining an intruder (for example, a subject 201) in a monitoring visual field with both a horn speaker 204 and an ITV camera 202. Was. For this reason, there is a problem that it is necessary to secure a wide installation place and that the equipment cost is increased in order to install at least two devices.
2 includes a video monitor 203 for displaying an image of the ITV camera 202 and a sound processing unit 205 such as an amplifier for performing audio processing such as amplification of output or collected sound.
Using a horn speaker and an ITV camera, collect sound from a sound source in the monitoring field of view, output sound such as sound loudspeaking in the monitoring field of view, and capture an image of a subject in the monitoring field of view to perform monitoring in the monitoring field of view. No prior patent document on a system for monitoring the data could be found.
[0003]
[Problems to be solved by the invention]
In the above-described conventional technology, when performing monitoring by loudspeaker, sound collection, and video, at least two devices are installed, so that it is necessary to secure a large area for the installation site and the disadvantage that the device cost increases. there were.
An object of the present invention is to provide a monitoring system which eliminates the above-mentioned drawbacks, has a small installation area, and reduces equipment costs.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, the horn speaker of the present invention has a small electric zoom lens with an auto iris and an auto focus function and a small ITV camera incorporated in an equalizer section of the horn speaker.
Further, the horn speaker does not change the shape and size of the equalizer of the present invention. Therefore, the performance of the sound output function, the sound collection function, and the like is not affected.
Further, the surveillance system using a horn speaker is provided with a terminal section video output (BNC seat), a control section connector, and a power supply (for example, AC 100 V) input cable near the audio terminal.
[0005]
That is, the horn speaker with a built-in ITV camera of the present invention is a horn speaker that collects and loudspeaks a sound, and includes an equalizer unit and an ITV camera incorporated in the equalizer unit.
The horn speaker with a built-in ITV camera of the present invention is characterized in that the zoom lens of the ITV camera is an electric zoom lens.
Further, the surveillance system of the present invention includes an ITV camera for picking up a sound from a sound source in the surveillance visual field and for capturing an image of a subject in the surveillance visual field in an equalizer unit of a horn speaker for outputting the sound in the surveillance visual field. A horn speaker with a built-in ITV camera, a video monitor coupled to the horn speaker with a built-in ITV camera, and a video monitor for displaying the captured image, and a sound processing unit for processing the sound of the horn speaker, wherein the sound source and the subject are substantially on the same line The monitoring system is characterized in that accurate monitoring can be performed by becoming a monitoring system.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a sectional view showing a configuration of a horn speaker according to one embodiment of the present invention.
As shown in FIG. 1, an ITV camera lens 104 and an ITV camera body 105 are housed in an equalizer section 102 of a horn speaker body 101. Further, a lens opening 103 is provided on the front face of the horn speaker equalizer section 102. The video output, external control terminal, and AC input cable 107 are provided in the plug part 106. As shown in FIG. 1, an image captured from the ITV camera lens 104 through the lens opening 103 is output from the stored camera unit (ITV camera body 105) via the tangential line 106.
The horn speaker 101 performs the original sound collection or loudspeaking operation regardless of the camera operation. Also, as shown in FIG. 1, the front surface of the horn speaker main body 101, which is a sound collection and sound output port, and the lens opening 103 are substantially straight, and when sound is collected from a sound source in the monitoring visual field, The configuration is such that the sound source and the imaging visual field direction are substantially straight.
[0007]
FIG. 3 is a block diagram showing an embodiment of the monitoring system using the horn speaker of FIG. 1 according to the present invention.
As shown in FIG. 3, the horn speaker 206 having the built-in ITV camera of the present invention has a function of monitoring the output of the loudspeaker sound, the sound collection, and the video possessed by each device of the present invention. It is possible to have a device. In addition, since the sound source and the subject 201 to be monitored are on the same line, accurate monitoring, loudspeaking, and sound collection can be performed.
[0008]
In the above-described embodiment, the zoom lens of the ITV camera may be an electric zoom lens, and may be operated by an operating device (not shown) or may be operated by automatic switching.
[0009]
【The invention's effect】
As described above, when monitoring by loudspeaker, sound collection, and video according to the present invention, a system in which both a horn speaker and an ITV camera are combined to construct a system can be handled by one device of the present invention. It becomes.
In addition, since the sound source and the subject to be monitored are on the same line, accurate monitoring, loudspeaking, and sound collection can be performed.
