Abstract

The invention provides a high-definition video monitoring system which is started when abnormal sound exists in the environment. The high-definition video monitoring system is targeted. When abnormal sound is produced in the environment, high-definition camera shooting is started, high-quality video images are provided for video data within special periods of time, and clearer image data are provided for cases or accident analysis in the fields of public security, fire protection and the like.

Description

technical field [0001] The invention relates to an intelligent audio and video monitoring system, in particular to an audio and video monitoring system triggered by abnormal sounds in the environment. Background technique [0002] In recent years, stimulated and driven by factors such as the construction of a safe city, Beijing Olympic Games, Shanghai World Expo, Guangzhou Asian Games, Shenzhen Universiade and other security projects, as well as the rapid growth of video surveillance demand in various industries, China's video surveillance market has achieved extraordinary rapid development. The market scale expanded rapidly. Taking Shanghai as an example, according to statistics, the number of security surveillance cameras in Shanghai in 2010 was about 200,000. In 2011, the overall market size of China's video surveillance industry reached 23.04 billion yuan. However, most of the time video surveillance monitors meaningless pictures, and when an emergency occurs, the image...
