More than 20 years, video surveillance system from the first generation of 100 percent of the simulation system (VCR), to the second part of the digital system (DVR), to NVR/third generation digital systems (completely video cameras and network server) three stages of development. In this process, video monitoring system and equipment in function and performance has been greatly improved, but is still some inherent factor, which contains the limit as the monitoring in human physiological weakness, video surveillance system is also contains video surveillance equipment configuration and performance in function and limitations. The limiting factor of video surveillance system that are more or less, the existence of alarm accuracy and phenomenon, alarm, response time video data analysis, causing difficulty of defects in the system safety and practicality.

In recent years, along with the network bandwidth and storage capacity of computer processing capacity and the increasing quickly, and various kinds of video information processing technology, digital video surveillance system, network, and its height has obvious advantages of openness, and video monitoring system for flexibility and equipment performance ascension creates the necessary conditions, but also for the development of the security industry provides more vast development space, the new application mode and emerging market opportunities, and intelligent video surveillance network video monitoring is one of the most field application modes.

The concept of intelligent video

Intelligent video (IV), IntelligentVideo from computer vision (CV, ComputerVision) technology. The computer vision is artificial intelligence (AI), one of the study ArtificialIntelligent branch, it can be described in the image and the mapping relation between image, which can be calculated by the digital image processing and analysis to understand the content of video images. And video monitoring mentioned in the video intelligent technology mainly refers to: "automatic analysis and extraction of video source key information." If the camera as people's eyes, and intelligent video system or equipment, can be regarded as the human brain. Intelligent video technology using computer powerful function of data processing in video image analysis, high-speed mass data filter out the information users don't care only for monitoring, provide useful critical information.

Intelligent video surveillance network video monitoring, with digital basis, but also different from ordinary network video monitoring, it is a kind of video surveillance applications. The higher Intelligent video surveillance system is able to identify different objects, found the abnormal situation, monitor screen and with the fastest and the best way to alert and provide useful information, and thus can be more effective to assist security personnel to deal with the crisis, and the maximum reduce and phenomenon. In the global war on terror serious video monitoring of today, intelligence can become apparent to terrorism and handling emergencies powerful auxiliary tools. In addition, intelligent video surveillance also can be used in traffic management, customer behavior analysis, customer service of the safety, in order to improve the user's return on investment.

Intelligent video advantage

Intelligent video surveillance network video monitoring in the common basis, besides having the network video monitoring of known, video intelligent monitoring system can also bring greater gains user:

24x7 monitoring, all-weather reliable thoroughly changed completely by previous: safety staff to monitor screen monitoring and analysis of the model, through the embedded in a front-end web video cameras or equipment (the intelligent video server) for monitoring module of uninterrupted analysis.

Robert greatly improve the accuracy of alarm equipment (web front-end: video cameras and server) integrated powerful image processing capacity, and advanced intelligent algorithm, the user can more precise definition of security threats, effectively reduce the misstatement or omission, reduce useless.

Robert greatly improve the response speed: identify suspicious activity in public places (such as someone from a suspicious objects, or someone in the sensitive area of the time), in the security threat before it can tip security personnel concerned with related monitoring menu prepared in advance, the user can also more precise definition in particular threat appear to be taken action, and the monitoring system itself, to ensure that the crisis of processing steps to execute the plan accurately, effectively prevent in chaos because of the delay caused by human factors.

Video resource effectively, expand the application: it applied to the video resource security fields, such as using the mall lobby surveillance system of automatic identification of VIP customers, and notify the customer service personnel timely. Find the crowd when someone fall, promptly notify the store near staff to help. In addition, intelligent video system can also help retail boss statistics on the number of customers to patronize, sales analysis, etc.

Intelligent video main potential applications

Intelligent video applications generally can be divided into safety related application and safety related application two categories. Safety related application is in the present market main intelligent video applications, especially in the September 11, 2001 terrorist attacks, the London bombings in Madrid bombings and, after the application, the market demand growth. In these applications, main effect is to assist the government agency or other departments to improve the security of large outdoor public environmental safety protective region. These applications include: advanced video moving Object detection (AdvancedVMD), MotionTracking), tracking (facial recognition (FacialDetection), Vehicle Identification (Vehicle Identification) and illegal detention (Object Persistence), etc.

Besides safety related classes, intelligent video applications can also be used to some of the safety of the application of relevant. These applications mainly facing retail and service industries, and can be regarded as the auxiliary tool management and service, to improve service levels and turnover. These applications include: (PeopleCounting), the number FlowControl crowd control (attention), AttentionControl) and Traffic control (Traffic Flow control (Flow), etc.

Intelligent video market situation at home and abroad

From the perspective of market demand, with terror, situation of intelligent video surveillance system is more and more cause the attention of people, rising demand in the process. In general, the foreign intelligence video applications market is from "concept" stage "scale to verify application" phase transformation, intelligent video has slowly began to form for an industry.

In the application of intelligent video concept model, shortly after some foreign companies have started research related to the software and hardware products. For example, network video market leading manufacturer of global Axis network communications Co., LTD, Sweden has launched its intelligent video products, including video server AXIS242SIV Axis and the number of intelligent video IVM 120 application module. AXIS 242S IV integrated with special DSP (TI), with a powerful DM 642 image processing ability, and can support third-party applications software module of operation and development. AXIS IVM 120 toll can make video intelligent video surveillance application module for monitoring equipment through the analysis for the users automatically images into a specific area calculating the number /, can effectively help service, retail industries or business management analysis improve service quality. Axis also plans to launch more in the near future, including video intelligent application modules within identification, illegal detention, etc.

Compared with the foreign and domestic intelligent video market still have a large gap, at present basically still blank. Generally in monitoring system of "mentioned in the video intelligent surveillance" actually still stays in the network video monitoring (ordinary digital control), IP monitoring the concept. But along with the market abroad and similar applications, intelligent video has some domestic manufacturers began to introduce foreign well-known manufacturers of intelligent video software and hardware products and technology, planning to use in the form of domestic OEM.

summarize

Intelligent, digital and network video monitoring is an inevitable trend in the development of the intelligent video surveillance, it appears the trend of direct embodiment. Intelligent video surveillance network video monitoring than ordinary equipment possesses stronger image processing and intelligent factors, it can provide more advanced video analysis function, it can greatly increase the video monitoring system, and the ability of video that could play a bigger role.
