Brief Analysis of the Current Situation and Future Prospect of Mobile Video Monitoring Technology



With the continuous development and progress of the information society, mobile video surveillance technology has emerged in the field of digital video surveillance, which can be called mobile video surveillance as long as the video source or receiver has mobile capability. The core technology of mobile video surveillance is streaming media technology. The birth and development of streaming media technology makes it possible to realize video surveillance on IP network. In the mobile video surveillance system, video signals are collected, coded, compressed, streamed, transmitted, and distributed relay to achieve the purpose of end-user monitoring.



Mobile video surveillance is a dynamic form of mobile video image acquisition in the front-end; the back-end is a professional-level surveillance product closely integrated with the security industry, receiving in a mobile way, such as: mobile phones or computers can achieve the function of monitoring remote real-time dynamic pictures, providing a simpler, more convenient and timely monitoring solution for enterprises and families. Mobile images are captured and coded by acquisition devices. Mobile satellite devices are used to transmit mobile signals in the air through CDMA/EDGE/3G multi-channel devices. Urban network coverage technologies such as WiMAX, 2.4G, 5.8G are combined with CMMB systems for mobile phones, PDA, MP3, MP4, digital cameras and notebook computers. Mobile video surveillance network composed of mobile transmission and mobile reception.



Mobile video surveillance includes front-end image sampling device, image transmission and receiving device, back-end image database and processing system, which are widely used in many fields such as home security, campus security, traffic information, security and on-site command. Mobile video surveillance is developing rapidly in developed countries, and is showing a broad market prospect in the world. So what is the current development status of mobile video surveillance technology? What are the prospects for the future? Next, we will analyze these problems one by one.



_. Development of Mobile Video Surveillance



_1.1 Market Situation



Compared with wired network, wireless network has the advantages of flexibility, high efficiency, fast construction, long-distance and low cost in video surveillance applications. With the popularity of video surveillance applications, wireless networks have been rapidly promoted in video surveillance applications. More than half of the projects in the survey are considering the implementation of wireless networks to achieve surveillance needs.



_Rapid evolution of wireless technology is the fundamental driving force for the development of wireless surveillance market. Relying on leading wireless technology, combined with rich experience in wireless network planning and project implementation in many industries, as well as comprehensive advantages in R&D, service and brand, more and more customers are aware of the importance of wireless video transmission, especially involving Safe City Surveillance and forest. In many fields, such as fire prevention monitoring, tunnel monitoring, park scenic spot monitoring, port and wharf monitoring, wireless applications have made many demonstration and representative monitoring applications.



In the video surveillance application project, the favor of wireless network naturally has its reason. Firstly, after ten years of development, wireless network technology has been very mature, and the price is very low. Secondly, video surveillance has been widely used in various industries, and has developed rapidly to a wider and deeper application; secondly, there are more and more large-scale monitoring systems. Based on the network, the rapid development of all network monitoring technology and market has further promoted the construction of the basic network. It is for the above three reasons that a huge wireless monitoring market has emerged. With strong demand and technical support, more and more network companies are involved in the application of wireless video surveillance, which has led many companies to promote the application of wireless video surveillance. Many manufacturers of wireless products are also actively making their own efforts for the wireless surveillance market.



_1.2 Technology Status



Mobile video surveillance can collect dynamic mobile video images and receive them in a mobile way through professional surveillance products. Users can monitor real-time dynamic pictures remotely through mobile phones or computers. Simpler, more convenient and more timely monitoring solutions have been realized. Mobile images are captured and coded by acquisition devices, and fidelity processing is carried out by Hanhsx optimization algorithm. Mobile signals are transmitted in the air through multi-channel devices such as CDMA/EDGE/3G, Hanhsx ultrashort wave devices and mobile satellite devices. Using WiMAX, 2.4G, 5.8G and other urban network coverage technologies, mobile phones, PDA, MP3, MP4, digital cameras and notebook computers are oriented. Mobile terminal realizes people's wishes of intelligent monitoring at any time and anywhere.



The technical advantages of mobile video surveillance are mainly embodied in the following aspects:



_1. High flexibility



_Modern production enterprises require video surveillance without dead angle. Wireless video surveillance system is not limited by cables and has flexible expansibility. It can easily add new surveillance points anywhere in the factory area at any time. It can also change the position of the old surveillance, increase the position uncertainty, and make the security surveillance truly implemented.



_2. Comprehensive low cost



_Comprehensive low cost, only one-time investment, no need to dig ditches and bury pipes, especially suitable for outdoor distances and well-decorated occasions; In many cases, users are often limited by geographical environment and work content, such as mountains, ports and open areas, and other special geographical environment, cable network, cable transmission wiring engineering belt.
