Clearly ordinary analog camera monitoring needs of people unable to meet intelligent, cheap analog cameras are the mainstream products on the market a few years ago. They are used in residential, corridor and other places have barely enough, but gradually it is difficult competent security functions in banks, railway stations, shops and some specific occasions. By the time the technical level of development restrictions, mostly traditional video surveillance system can be simulated on-site monitoring, image transmission can not be guaranteed recognizable, unable to timely and accurate understanding of the actual situation at the scene, alarm events confirm difficulties, low system efficiency. Since the analog monitoring equipment itself, the physical limitations, making the monitoring of short distance, unable to realize a wide area surveillance. Also due to the lower production threshold analog control, product quality varies greatly. These factors together led to the rapid development of mobile surveillance as the representative of high-definition monitor. Mobile video surveillance can quickly dominate the market, largely due to its advantages: a movable manner to receive dynamic form of video image through professional-level monitoring products. Users can remotely monitor real-time dynamic promptly by phone or computer screen, easier, more convenient and timely monitoring solutions have been achieved. The moving image capture device encodes information collected by Hanhsx fidelity process optimization algorithm, through CDMA / EDGE / 3G multi-channel devices, Hanhsx VHF equipment, mobile satellite equipment for aerial moves signal transmission, the use of WiMAX, 2.4G, 5.8 G and other cities network coverage technologies for mobile phones, PDA, MP3, MP4, digital cameras, laptop computers variety of mobile terminals, intelligent monitoring of the desire of people anywhere, anytime. Today, mobile video surveillance market definition ip cameras have become the main product, its good image effect, versatility, adapt to the environment is strong, long service life, monitor distance, can recognize human faces in a larger context, true to the site situation.
Mobile video surveillance in the security market, the occupation of the mainstream market, and is an important financial, government, security and other support services to provide a larger area, but it still has some problems to be solved. For the user, on the level of high-definition technology, 4G network technology, big data, intelligence analysis can come in handy in the mobile video surveillance products, but in the transmission, image analysis, storage, monitoring and other aspects of the night still need to be resolved technical problems. To the mobile video surveillance products applied to more areas, we must address these problems. HD ip cameras usually choose 720P or 1080P solution. To achieve the desired image effects, network bandwidth requirements are relatively high, the stability of network requirements are relatively high. If the point of a system to monitor them more, then the entire network data flow will be quite large, and the video stream is real-time data streams, will continue to network-related equipment caused by sustained pressure on the exchange, which requires the network planning solve the problem. Many of the HD manufacturers just focus on the front of the camera pixels, without a corresponding development of high-definition video, can only lead to customers around the PC screen to watch high-definition images, high-definition image can not be displayed in a separate large on the screen. For this problem, we developed a number of security companies need to pay attention to high-definition, will be transmitted over the high-definition graphical front-end to effectively restore, connect to large-screen high-definition input interface, the high-definition picture perfect show in the screen above. If the data center or converge to each node for storage, bandwidth pressure on the central entrance and storage capacity is a big challenge, so the development of cloud storage will be the direction of development. In the case of day-lit, high-definition is a very easy thing, when once used in low light or at night need to monitor, HD feature is utterly useless. Since most HD ip cameras using CMOS sensors, the lower its sensitivity to light, if not with infrared light, the night is dark, and we monitor most of the time period you want to guard against is precisely at night, so high expectations of high-definition video systems will become a decoration. Security companies offer different solutions depending on the site environment, such as infrared light program, IRCUT technology, illumination chips.
Applications for mobile video surveillance products are facing a lot of problems, and security companies to find a real solution to the problem: First, solve the problem of data collection. Collected at the scene to ensure there is no missing critical information; Second, data mining how to be transmitted to a special "destination" problem. May be a different place, industry data are scattered and divided in different small place, needs a stable technology to the information back to the terminal system; third is how the data analysis of these data. Through data analysis program allows users to get the perfect experience, no job guarantee security blind spots and mistakes and so on. All along, the network speed transmission reach mobile monitoring requirements are restricting the development of technological bottlenecks in the field, but will now roll out 4G mobile video surveillance networks to bring new business opportunities. In recent years, the development of mobile video surveillance and 4G network technology development are closely related. 4G is the rapid development of the industry chain, has been extended to mobile video surveillance industry. Many famous manufacturers have been initially launched with a 4G function monitoring product solutions. Mobile video surveillance products under the 4G network technology can help the timely delivery of live high-definition picture and big data back to the user, and will be more widely used in China is a developing trend of the security industry.
In the era of big data, people are more intelligent video analysis technology value. Intelligent video analysis relies on the video content analysis algorithm to the video, the key information by extracting the video, or the associated marking process and the formation of the corresponding event and alarm monitoring methods, it can be quickly retrieved by a variety of attributes. Intelligent video technology with powerful computing capabilities processors on the video screen in a high-speed analysis of massive data, access to information that people need. Previously, under artificial view mode, the traditional method requires sequential play video from beginning to end, can not solve the problem of information analysis. With intelligent video analysis technology for moving objects, such as video retrieval and exclusion, you can quickly search for information from the mass to the information they need, can greatly improve work efficiency. After the intelligence analysis technology into mobile video surveillance, and achieved good practice effect, which led to faster mobile video surveillance product upgrading. Intelligent analysis technology in a variety of mobile video surveillance industry: The perimeter guard, people counting, automatic tracking, retrograde, Jinting and other rules for the behavior of the representative of the analysis techniques to license plate recognition, face recognition as the core of the representative of the intelligent recognition technology applications are very extensive.
