In the case of basic structure, microphone array 13 is added on the pedestal 11 of ball base camera 1, microphone array 13 includes multiple
Microphone, single microphone can be to have directional microphone or be no directional microphone, and microphone array 13 is used to pick up
Take the multichannel acoustic field signal around ball base camera, the vision signal that ball base camera 1 shoots movable camera part 12
And the multichannel acoustic field signal that microphone array 13 picks up is sent to main frame 2 by the bidirectional communication link, main frame 2 includes locating
Unit 24, video monitor unit 21 and audio select unit 22 are managed, wherein processing unit 24 is used to believe vision signal and sound field
Number handled, and the vision signal after processing is sent to video monitor unit 21 and shown, by the multichannel after processing
Acoustic field signal sends to audio select unit 22 and reset, wherein, as shown in Figure 3, processing unit 24 is to multichannel sound field
The processing of signal includes：According to the current shooting visual angle direction in movable camera part 12, such as the A directions in figure, to multichannel
Acoustic field signal, which synchronizes, to be rendered, and synthesizes the local acoustic field signal A ' of the view directions, when the bat of movable camera part 12
Take the photograph after visual angle changes, the B directions that have such as gone in figure, then synchronized compound goes out the local acoustic field signal B ' of the view directions, passes through
This mode, the uniformity and specific aim of video and Voice Surveillance can be greatly enhanced, be obviously improved the effect of monitoring evidence obtaining.
Further, the processing unit 24 of main frame 2 also includes memory module so that supervising device of the present utility model except
Carry out that monitoring in real time is outer, can also simultaneously by vision signal and the shooting visual angle directional information of corresponding movable camera part 12,
Audio signal is recorded, and later stage user can transfer the information inspection of storage at any time, and processing unit 24 equally can root
According to current shooting visual angle direction, synthesize the local acoustic field signal of the view directions so that user can be directed to what is recorded
