China's security industry has experienced 30 years of development, and video surveillance, burglar alarms, and access control recognition have performed well in their respective fields. The surveillance-based China security market is expected to be a blockbuster during the "12th Five-Year Plan" period, with a total market value of 500 billion yuan. However, in this huge video surveillance field, small details will always be ignored. Although it is insignificant, the application value is undoubtedly obvious. The endless new methods of crime also force security technology to face new challenges. The video surveillance system is gradually transformed from a single analog monitor to a high-definition digital monitor. It is transformed from a stand-alone monitor to a network monitor. The addition of intelligent identification technology improves the monitoring efficiency. It can be seen that with the increasing security monitoring requirements and the overall progress of technology, the monitoring of traditional single video can no longer meet the needs of different fields, and audio is expanding into even the necessary functions.
The core component of audio monitoring is the pickup. For an integrated audio-video surveillance system, the camera is like an eye and the pickup is the ear. Images and sounds are transmitted via a network to a hard disk recorder or monitoring center, which forms a basic audio and video recording data after being saved. Current security products and systems have less support for audio expansion, and most of them cannot be used for high-end applications such as two-way talkback and synchronization. In order to meet the requirements, some manufacturers specifically increase audio coding. Audio and video devices are independent of each Other and therefore it is difficult to achieve synchronization. The relative delay of sound and images is relatively large.
There are also some people who oppose the importance of audio monitoring. It is thought that audio monitoring will infringe on personal privacy, and some people think that audio monitoring is unnecessary. In reality, audio monitoring has become an integral part of many areas. Judicial departments, traffic police enforcement, subways, and public places in important locations all require audio monitoring, and audio monitoring is easier to implement. This is not only a constraint on individual behavior but also the key to national law enforcement for government officials. Audio and video surveillance has not only strengthened the law enforcement supervision of the public security organs, but also effectively safeguarded the legitimate rights and interests of the people's police and the parties. At the same time, through more comprehensive monitoring data, we have changed the passive situation in which the people complained that the police could not identify and improved the efficiency of complaint investigation and handling. Audio monitoring has been widely used in schools, supermarkets and other places. It is worth mentioning that campus security has become a top priority for government work. While strengthening personnel inspections, technical facilities are also being strengthened. Key areas such as campus gates and playgrounds are the focus of security monitoring. Audio and video surveillance has become the best means to handle emergencies in a timely manner.
Audio Surveillance Makes Up Video Surveillance Blind Spot The monitoring mode of current audio and video synchronization has become an industry consensus. As Feng Zhengang, General Manager of Beijing Fast Fish Technology Co., Ltd. puts it, “Monitoring the picture to achieve audio and video synchronization is the development trend in the field of security, facing the sudden In the situation, the video and audio synchronization monitoring screen can also provide staff with more sufficient judgment basis and help the rapid formation of decision-making." Audio monitoring has undergone five years of baptism, and now it has entered a phase of rapid development; if the government and The relevant departments can vigorously support the construction of audio monitoring and formulate relevant laws, so audio monitoring will surely have a splendid and beautiful tomorrow.
Audio monitoring has become an indispensable part of the surveillance system. More and more manufacturers have joined the audio monitoring team. More and more security engineering companies are aware of the importance of audio monitoring. Security will be brought to the new cleanliness.
