[0034] As can be seen from the above description, the beneficial effect of the utility model is that the monitoring camera provided by the utility model collects sound through the sound source collection component, and the main control module identifies the sound in the environment and locates the sound to amplify the corresponding position area in the image collected by the image collection component 2 to achieve panoramic monitoring.

[0037] Furthermore, the image acquisition component 2 also includes a fixing frame 22 , which is disposed at the bottom of the first cover body 12 , and the plurality of lenses 21 are evenly distributed along the circumference of the fixing frame 22 .

[0038] It can be seen from the above description that multiple lenses 21 are modularly assembled through the fixing frame 22, which can not only reduce the difficulty of installation, but also reduce the cumulative tolerance of the multiple lenses 21 and improve the stitching accuracy of the images captured by the multiple lenses 21.
