The Importance and Future Development of Audio Surveillance in Public Facilities
Posted on

How important is audio equipment in the construction of public areas?

Application of Audio Surveillance in Public Facilities and Places
At present, audio monitoring has been widely used in public facilities. A complete set of audio monitoring system includes a sound collection part, a speech noise reduction part, a network recording part, a voice intercom part, and a sound intelligence analysis part. Through the scene analysis of audio monitoring to determine abnormal behavior in public scenes, this technique is based on the characteristics of various types of abnormal sounds in the time and frequency domains. In combination with pattern classification methods, abnormal events can be alarmed.
The sound collection part is the core of the audio monitoring system, mainly through the vibration of the sound to collect the sound of the scene. As a leader in the audio monitoring industry, Fast Fish has never dared to relax in the market segments. From sound collection to sound intelligence analysis, it has accumulated a lot of technology. Through years of publicity and promotion, the concept of audio monitoring has been expanded. Into the hearts of people, adding a touch of color to the security industry, but also promoted the security of the public sector.
At present, guojia must have audio synchronization for some special venues, occasions, and video requirements. For example, the Procuratorate interrogates simultaneous audio and video recording systems, the public security bureau pre-approval system, and the detention center's prison supervision system. Tiananmen Square, Zui Gao Court, guojia petition office and other important guojia institutions, as well as Beijing Metro, Capital Airport and other public transport hubs also have audio monitoring. In addition, audio monitoring has applications in highways, schools, and banks.
The effective combination of audio monitoring and video monitoring

Now that video surveillance is still in the mainstream market in the surveillance industry, how can audio monitoring be integrated into video surveillance? The author believes that the corresponding company of audio monitoring should strengthen cooperation with mainstream video surveillance manufacturers, integrate advanced audio intelligence analysis in video surveillance systems, and eliminate the so-called “blind spots” in surveillance. Through the intelligent analysis of the abnormal sound at the scene, 360-degree comprehensive monitoring and early warning can be achieved.
Like video surveillance, audio surveillance also faces changes in digital intelligence. Massive audio data can only make more sense through intelligent analysis and discrimination, rather than staying in the basic functions of storage and monitoring. Fast Fish Electronics has invested more than four years in technology research and development in speech recognition, voiceprint recognition, and sound scene analysis. Currently, it has made great progress in technology. Fast Fish Electronics will gradually release relevant intelligence in 2016. Voice product.
Future development of audio monitoring

Audio and video surveillance is an important part of the security system. It is a comprehensive system with strong prevention capabilities. It is intuitive, accurate, timely, and informative. Most of the traditional monitoring systems do not have sound, people can only see silent images, and audio monitoring has not been well promoted.
With the acceleration of the development of safe cities, the requirements for the construction of security systems have gradually increased. People have begun to pay attention to audio monitoring. Now, more industries and scenes are increasingly demanding the simultaneous monitoring of video and audio.
In the future development, products should be expanded from aeroacoustics to solid acoustics through audio analysis capabilities and technologies: abnormal sound detection of railway tracks, abnormal sound detection of oil and gas pipelines, abnormal sound detection of bridges, acoustic detection of seismic waves, and the Wall sound alarm and so on.
to sum up
Audio monitoring, as a branch of the security industry in recent years, has been rapidly developing, and its application points have been expanding in recent years. People are also turning their attention away from the need to see and hear to the search for high-quality audio and video surveillance. Now the field of audio monitoring has become a new bright spot in the security industry.

PVA Resin
