The earliest video surveillance system is an all-analog video surveillance system, also known as closed-circuit television monitoring system (CCTV). Image information using video cables, transmitted in an analog manner, the general transmission distance can not be too far, mainly used in a small range of monitoring, monitoring images can generally only be viewed in the control center. All-analog video surveillance system to analog video matrix and tape-based recording equipment VCR as the core.
With the development of digital technology, digital video surveillance system from the mid-1990s began to appear to the digital control of the video matrix to replace the original analog video matrix, digital hard disk recorder DVR to replace the original long-delay analog VCR, the original tape storage mode into a digital storage video, the realization of the analog video into digital video.DVR collection of video recorder, screen splitter and other functions. DVR collection of video recorders, screen splitter and other functions, the first step across the digital monitoring. On this basis produced a fully digital video surveillance system, can be based on PC or embedded devices constitute a monitoring system, and multimedia management. This type of system is the mainstream of the current video surveillance market.
With the popularization of broadband networks, video surveillance has gradually evolved from local monitoring to remote monitoring, and remote network video surveillance systems represented by network video servers have emerged. Network video server solves the problem of video streaming transmission on the network, digital processing and transmission from the beginning of the image acquisition, which makes the choice of transmission lines more diverse, as long as there is a network, it provides the possibility of image transmission. The whole system tends to be platformized and intelligent. Many Internet companies have begun to get involved in the development of such video surveillance systems, the market is still in its infancy.
Today, we will see a variety of surveillance cameras in the retail market. As network cameras continue to improve, integrators and their users will find more applications. Verticals in the city surveillance, transportation, and healthcare industries will grow significantly with the efficient operation of surveillance systems. The residential market is another direction to watch. Many people have already tried to sell cameras for home use, and I believe that with the deeper application of hosted video, cameras for home use will also become a major development highlight.
In terms of video applications, more regulations will be introduced, but the location of the camera set up the requirements will be reduced accordingly. The cost of deploying camera systems will be reduced, mainly due to lower storage and installation costs, and software costs are also likely to fall. Given the growth rate of the industry and the emergence of new applications, we will see more camera products on the market than we thought possible.
With the continuous intensification of competition in the video surveillance equipment industry, large video surveillance equipment enterprises between mergers and acquisitions, integration and capital operation is increasingly frequent, the domestic outstanding video surveillance equipment enterprises pay more and more attention to the study of the industry's market, especially on the development of the business environment and customer demand trend changes in-depth study. Because of this, a large number of domestic excellent video surveillance equipment brand quickly rise, and gradually become the leader in the video surveillance equipment industry!
