  • 2013 monitoring network nationwide research and analysis

        In recent years, with the constant expansion of the video surveillance system, the deepening of the application, the system integration needs increasingly strong; rising demand shared by the public security organs at all levels of remote image resources; Zhu police concurrent image resource sharing conflicts have become increasingly prominent; transverse cross-regional demand for image sharing increasing. Social order dynamic video surveillance system sharing platform is particularly urgent. Monitoring network nationwide, to promote the development of the national security industry, then monitor a wide network to bring the monitor to save their own impact?
        Status: monitoring large networked nationwide
        Example, Shaanxi Province, Shaanxi Province has built video surveillance system of the main problems is the low degree of sharing of system resources, image information system technology standards are not uniform, relatively independent screen monitor image resources is difficult in the city, provincial Regional Intranet shared. Relevant statistics show that public security organs surveillance video system detected cases accounted for 1/3 of the total number of detection, so all video surveillance Interconnection, interoperability, mutual control is very important. The Shaanxi fact almost every place on common problems.
        Public security organs in video surveillance network construction has a very important strategic significance, "networking" can effectively solve the problem of "islands" greatly enhance the surveillance images comprehensive utilization of resources, thereby enhancing public security organs cooperative engagement capability to effectively combat crime. In many parts of the tireless efforts and explore.
        Zhejiang Provincial Public Security Department as early as 2004 on the establishment of the research team, to carry out research on the subject, and has assumed the Ministry of Public Security Science and Technology Bureau (now the Science and Technology Information Bureau) "social order dynamic video surveillance system sharing platform" Provincial Science and Technology Department of the Yangtze River Delta social security network monitoring system to share research and application "project, carefully organized major scientific and technological project of the Provincial Science and Technology Department of the Yangtze River Delta social security network monitoring system shared research.
        To promote the province´s public security organs video surveillance network construction, the Shaanxi Provincial Public Security Bureau set up a special leading group of video surveillance networking platform.
        Recently, Jiangsu, Zhejiang, Anhui and Shanghai police held in Nanjing, Jiangsu, Zhejiang, Anhui and Shanghai regional police co-operation of the third Joint Committee, public security organs of the four image information-sharing applications Cooperation Framework Agreement signed at the meeting. Signing the commitment of the parties on the open sharing of regional police information data base, and gradually establish image information sharing mechanism to support security for cross-regional command and dispatch, traffic management, security precautions, investigating this case, serving the people of public security work. The share content adjacent to the contracting parties of the image information of the region, regional major criminal cases involved in video data and other need to temporarily call shared surveillance images. Four police will establish a shared image monitoring information system, assign permissions to the province, city and county public security organs three business units to carry out combat application. This marks the Jiangsu, Zhejiang, Anhui and Shanghai police in the future will be shared image monitoring information, coordination.
        These all show that video surveillance "networking" has become an inevitable trend.
        Perspective: monitoring and control network is not the ultimate goal
        Around the video surveillance system in recent years, the use of construction exposed some of the main issues will be resolved through the unified construction video network networking platform, a complete end discrete video surveillance system construction due to the lack of unified planning, the lack of uniform technical standards, platform architecture expansion capacity is limited, the lack of multi-force business communicate with each other and other defects and shortcomings, formed through the efficient sharing of resources, adequate resources and overall advantage.
        However, just by the platform for the construction of the majority of video surveillance resources into a unified, unified view, unified operation, unified playback, you can effectively enhance the core combat effectiveness of the police and front-line efficiency? Answer is no.
        Platform for the construction and monitoring of resources Internet is only the first step, is not the ultimate goal. With the wide-area monitoring resources to achieve centralized call, the video data will be massive growth. If still the traditional "look, control, storage, management" as the system requirements of the building and monitoring usage patterns will inevitably produce emergencies processing steps to increase processing speed slows down after the incident video to find inefficient, video information unable to access police to consume huge even solve the case cycle prolonged negative impact.
        Thus, we see that the public security organs across the video image information integration and sharing of tasks book "special emphasis on the" promotion of video surveillance technology depth "," close combat, combat service "," around the actual needs of public security "," efforts to enhance the capacity of the real struggle of the public security organs of video surveillance technology and other critical infrastructure principles.
        To effectively the video surveillance system transformation for the actual combat effectiveness of first-line services in public security each police kinds of real reality business work, shorten the reaction time, reduce the human cost video surveillance platform for networking in addition to achieving the traditional "look, control, save, tube" the basic video business, to be able to interoperate existing multi-service system and public security integration. For example, to achieve the video surveillance system to share information with other police systems, flexible query, intelligent identification, behavior analysis, video case database management, integrated police information management functions; establish a coordinated and orderly, rapid response, smooth command public security and emergency command and communications system; do service merits public security detection as the core, to take full advantage of video resources to provide effective clues, cross-sectoral, cross-police information sharing and application sharing.
        : Monitoring LinuxTimes monitoring NVR assume more
        In the conventional monitoring system, DVR has been the mainstream storage work. However, with the transformation of the overall application mode in the future storage applications, NVR than the DVR will assume a more important task. In future applications, embedded perfect as one of the main direction of development of the kind of video storage devices. Because of its progress in networked applications, the monitoring system for the needs of embedded constantly upgrading. Especially in the intelligent management of video, high-capacity storage technology advances, and video access, storage, stored and playback, will serve as the main expectations of future technological developments.
        In addition, the demand for high-definition capabilities. HD IP camera market in recent years, fast, and has begun to gradually gained popularity, the application of high-definition cameras enable the market has become increasingly strong demand for high-definition monitor. True high-definition monitor, high-definition cameras is really just a part, if there is no back-end codec and synchronized with display technology, high-definition monitor is still only on paper. As the center of the monitoring system equipment, NVR is undoubtedly have more expectations in the ring, it first has reached a high-definition display technology. Mainstream NVR products currently on the market already has HDMI digital high-definition interface, you can achieve a display resolution of 1920 × 1080. With high-definition monitor needs more management applications in the future, in terms of clarity NVR will be doomed to continue to maintain the lead situation.
        The most important storage areas as a monitoring system, stability is most concerned about. In the course of their work, the NVR on the basis of the network, but the complexity of the network bearer service, leading to instability in the network, and therefore directly affect the stability of the bearer traffic on the network. Especially for video surveillance, it is absolutely can not be ignored, may be due to temporary failure of the network will be a direct result of the lack of video, and video information on the importance of video surveillance is definitely bear the brunt. Network instability leads to the loss of video data became NVR confrontation DVR battle the most deadly pitfalls, this is the future NVR need to continue to focus on areas of concern.
        In addition, cloud computing is now regarded as an effective means to solve some large-capacity or storage With cloud applications continue to penetrate in the security, the combination of cloud technology and NVR also likely to become the main direction of future applications. High-definition and high-capacity influx brings more to our video surveillance harvest, but after the preceding enjoy, how to better deal with post-processing of these resources, we need to pay special attention to . With high-definition network technology and practice with the traditional monitoring system gap growing in monitoring storage concept, destined to open up a new path. This new road will be doomed to lead us to harvest more surprises in the security and sublimation.
        Infrared thermal imaging surveillance not only to make up for the deficiencies of the traditional video surveillance system, and enhance the security system, automatic identification, automatic alarm degree of automation, has a very important role in society, and has broad market, especially thermal imaging network monitoring system, represents the development trend of the infrared thermal imaging surveillance.
        In this paper the Intelligent Transportation thermal imaging surveillance applications, for example, to explore a wide range of thermal imaging application and network monitoring trends.
        Effect of thermal imaging intelligent transportation applications
        The thermal imaging infrared surveillance cameras are widely used in the field of Intelligent Transportation (ITS), with the rapid maturing of the front-end equipment market, and promote the development of intelligent transportation applications. Thermal imaging surveillance cameras from low-light, sun glare interference can be automatically excluded from the shadows and harsh climate impact, which is the traditional surveillance cameras can not match advantage.
        Infrared video surveillance cameras can be applied with the road intersection control and narrow lanes road monitoring detection, the core is the application of video image processing software. This minor upgrade can be used for large-scale security applications, forward-looking infrared surveillance technology can improve the processing technology of intelligent video analysis. Thermal imaging surveillance cameras is not a singles solo, often with the use of perimeter intrusion detectors. FLIR camera with video analysis technology to combine and integrate into a powerful road monitoring system and services in cities around the road monitoring.
        The thermal imaging applications in the transport sector is mainly manifested in two aspects: detection control car through the intersection lights along the highway with the automatic detection event. Day or night, thermal imaging provides clear video images, it is from the sun, almost from the external environment control. Therefore, thermal imaging detection vehicles and pedestrians in the intersection of the prevailing situation is very accurate, to meet the 7 * 24 hour real-time monitoring requirements.
        Applicable to the field of traffic security surveillance cameras are many different kinds, through the fog, wide dynamic surveillance cameras, how can both ensure the effect of the image but also to meet the low-light environment monitoring? Addition to the traditional external LED fill light, in fact, a lot of the advantages of thermal imaging infrared technology .
        Infrared thermal imaging applications in many fields
        Recently, crazy H7N9 avian influenza confused panic, major airports aviation to ensure passenger An Quanshun smooth off the installation of a temperature sensor, a higher degree of automation infrared temperature monitoring system, invisible detection temperature.
        Of course, the thermal infrared imager thermal infrared monitoring is not a small difference, the thermal network cameras can solve the previous thermal imager single work, the inconvenience of installation can not be real-time online monitoring of a range of issues, infrared surveillance cameras through the network can be thermal imaging real-time image returns to the monitoring center for analysis, as an effective complement to visible light camera, greatly enhance the real-time monitoring system, effectiveness.
        No matter what kind of infrared surveillance technology, thermal imaging infrared surveillance cameras not only provide high-definition video images, but also can be integrated intelligent analysis technology to achieve the dual monitor the effect of the high-definition intelligent thermal infrared monitoring, road monitoring, there is much room for development .
        Thermal imaging network monitoring trend
        Compared to traditional thermal imaging devices, the thermal network cameras can solve the previous thermal imager single, installation is inconvenient to use, requires a lot of manpower equipped, the data can not be timely and effective and belongs not online real-time monitoring of a range of issues, can do thermal imaging monitoring information into the entire network monitoring platform, no real legacy weather a wide range of monitoring. Through the network, real-time thermal imaging image returns monitoring center for analysis as an effective complement to visible light camera, full coverage for the monitored object, the scope of monitoring, timely and accurate processing, greatly enhance the real-time monitoring system, effectiveness.
        Infrared thermal imaging camera infrared thermal imaging surveillance system equipment, mainly used in some of the important areas of equipment and perimeter monitoring, such as the important warehouse, building, and key buildings, ports, border and other occasions. Can also be applied in forest fire prevention, as well as power (such as transformers and lines), oil (especially the input pipe), mine key points and equipment monitoring. 0Lux cases can monitor the unique advantages of infrared, in the absence of any light environment, fog, bad weather can effectively find the target. Infrared temperature measurement capabilities, electrical equipment such as transformers work abnormalities, or the prevention of forest fires and other key security projects can play an important role.
        Rapid growth in the future
        The video image is loaded a lot of information, it is not only the image pixel, determine the quality including temperature. Most intersection monitoring probes external lighting, for monitoring costs seems to be very considerable. With the falling prices of infrared thermal imaging surveillance cameras, mounted directly on the infrared surveillance is more cost-effective than the cost of external lighting. At the same time, thermal imaging the spirit of green technology, help to reduce the use of expensive intensive lighting equipment to reduce energy consumption.
        In addition to applications in the transport sector, thermal imaging monitor also has a good performance in other areas. For example, forest fire prevention. In addition to the night can be used as the site to monitor the use of infrared thermal imaging by reflecting surface temperature, and preventive measures for fire detection. Application of infrared thermal imaging can quickly and efficiently find the hidden fire accurately determine the location and extent of the fire.
        At this stage, the infrared thermal imaging surveillance in the country is still in the promotion phase, users or Party related functions generally not very understanding, and there is no unified understanding of its necessity, infrared thermal imaging surveillance real applications not many. But over time, some high-end markets such as the military, banks, armed police and public security system has this system form a correct perception, and with the increase in domestic terrorist activities, many areas have their clear use intention, I believe, infrared thermal imaging monitoring in the coming years there will be more rapid development.
        Thermal imaging surveillance
        Any temperature of the object will give infrared thermal imager is to receive the infrared rays emitted by an object to be measured through color images to display the surface temperature distribution according to the slight difference in temperature to identify the abnormal temperature point, and thus play and maintenance role. The working principle of the thermal imaging camera is a thermal infrared imaging technology. Its core is the thermal imager, which is able to detect extremely small temperature difference between the sensor and the temperature difference is converted into a real-time video image is displayed. But only see the thermal contour of the people and objects, can not see the true face of the object.
        Infrared thermal imaging surveillance not only to make up for the deficiencies of the traditional video surveillance system, and enhance the security system, automatic identification, automatic alarm degree of automation, has a very important role in society, and has broad market, especially thermal imaging network monitoring system, represents the development trend of the infrared thermal imaging surveillance.
