With the steady development of video surveillance industry markets,as well as market expectations of a good video surveillance market is gradually integrated into the information technology industry market from a closed narrow market. Intelligent Network Video Monitoring gradually replacing analog monitor, high-definition monitor gradually replace the SD monitoring has become an irreversible trend. Network HD video surveillance not only can give users a clearer image details, but also bring more intelligent analysis system data sources, greatly enriched the reuse and redevelopment of monitoring data, the use of monitoring systems for people with to a great convenience. HD video surveillance is a step change people's lives. Future, video security monitoring in the security role will become increasingly important. In addition, video surveillance images based investigative become the fourth largest criminal investigation of technical support. Future, integrated application security video image investigators application platform will be video information resources for the concept, close to the actual application of public security needs and achieve electronic prevention and control, video library, intelligence analysis and other deep applications, the establishment of a standardized case video collection and assessment processes. By portrayed, combing with information relevant to the case, to personnel, vehicles, building a database of cases classified as elements, to provide search, compare, track descriptions, case series and other functions, to narrow the scope of the investigation Mo Pai, locked the suspect goal of serving the public security crime prevention and control, case investigation, intelligence judgments and other police work, in order to prevent crack down on crime, maintaining social stability to provide strong support platform. Thus, the importance of video security in security monitoring in no doubt.

Video surveillance system in the peace project in the increasingly important role, how to ensure the quality of the network video surveillance industry has become the focus of all attention. Increased emphasis on video surveillance, video surveillance user expectations are increasingly high, and even suggested that video surveillance can clearly record all the details of the development of things, can solve all problems. However, the content and quality of the image with the changes in the external environment changes significantly, video surveillance is not a panacea! Such as lighting changes, rain and fog weather, distance, position blocking movement speed, camouflage dress and other factors have direct affect image quality , resulting in part of the image through post-image processing to improve image quality, while some images will be because of some uncontrollable factors, you can not restore the image content. Therefore, people should be rational look at video surveillance, recognizing the existence of the gap with reality, a reasonable set of expectations, in order to better application of video surveillance.

Throughout the implementation experience of network video surveillance throughout the country, an excellent HD quality monitoring systems often require skills upgrading in all directions from the whole to the details, can allow HD video surveillance for the people of life and property safety escort. However, the upgrade can not be separated with the revision to improve equipment performance quality technology. In 2012, front-end monitoring project used almost as an image resolution of standard definition devices D1 format, so clarity at this stage most of the original front-end equipment are low. Due to lack of front-end equipment performance, surveillance video screen blur, detail is unclear, some surveillance video in the text, face, clothing outline, license plate number and other details can not tell, resulting collection is missing critical information. So you want to go high-definition video surveillance, we must overcome this obstacle inadequate performance of the original equipment. Clearly, the vast amounts of video data processing beyond the limits of human ability. Video surveillance data processing to be implemented on intelligent use of computers in computing power much stronger than the human brain characteristics, combined with the advantages of human judgment, in order for video surveillance has become a fast and convenient, quality optimization of security measures.

Face to distinguish, for example, in a laboratory environment under theoretically has enough face samples condition, although many algorithms can do 99.9% recognition rate, but can only be used on special occasions, still can not be applied in surveillance applications. However, the gap between theoretical research and practical application of existence is inevitable. Only on the basis of theoretical research and practice, and collecting data, a rich database and improve the practical application problems found, improve accuracy, in order to gradually achieve qualitative optimization screen monitor. Throughout the course of the development of video surveillance, video surveillance through three different stages of development, now has a complete industrial value chain, the video surveillance market has developed into a more mature industry. HD video surveillance, is gradually changing people's lives, but want better video surveillance escort people still need to span several obstacles. Future, HD video surveillance will play a more important role in the security monitoring.
