摘要

A CCTV surveillance system for analyzing sound characteristics according to the present invention and outputting it together with an image comprises: a CCTV assembly including a camera for photographing an image and a microphone for receiving sound; A receiving module that receives the image and sound, a sound analysis module that analyzes the sound to determine a sound level, an image output device that outputs the image, and generates the sound when the sound level is higher than a preset level value. And a central control server including an output control module for recording and outputting the sound together with the image to the image output device. According to the present invention, it is composed of a CCTV assembly and a central control server, receives video and sound through the CCTV assembly, receives and analyzes it in the central control server, and outputs the video and sound together when the sound level is higher than a preset level value. When output to the video output device, visual information and sound are visualized and displayed, so that both the video and the sound are displayed, thereby improving the efficiency of monitoring work.
