Security industry video surveillance industry After the first generation of traditional analog CCTV systems, the second generation of digital-analog hybrid stage, the third generation of intelligent network video surveillance quickly emerged. The networked video surveillance system was designed for use in the network environment from the very beginning, and thus it overcomes the disadvantage that the DVR cannot obtain video information over the network. The user can monitor, record, and manage the video via any computer in the network. Real-time video information.
Network video monitoring includes two basic solutions: "analog camera + network video server" and "network camera + NVR." Thanks to the use of TCP/IP networks, the advantages of network video surveillance can be achieved by remote monitoring and low-cost expansion of the monitoring range. These advantages of network video surveillance make it greatly expand the application of video surveillance.
Since the beginning of 2012, demand for intelligent network video surveillance has been booming. Suppliers of IP cameras, NVRs, and network video switching equipment have been targeting this business opportunity. Face recognition, license plate recognition, large-scale successful industrial applications, well-known telecom operators at home and abroad And communications equipment manufacturers have also entered the field strongly to further promote the security industry's rapid development in the direction of IP intelligent monitoring. The development of the third-generation network video surveillance is moving toward the direction of intelligence, high-definition and mobilization.

The original International Radio Consultative Committee (CCIR) defined the definition of high-definition television: “The high-definition television should be a transparent system. The image quality that a normal-sighted audience sees at a distance of three times the height of the system’s display screen. It should have the impression of viewing the original scene or performance." It seems that when viewing the monitoring picture recorded by the DVR, the visual sensation should be at least as clear as the real scene we see on the scene. Currently, MPEG-4 and H.264 are the mainstream video compression technologies. The requirements of video monitoring equipment for video processing chips are mainly concentrated on the compression format, resolution, and ASIC/DSP. More and more equipment manufacturers need to support MPEG-4. /H.264 dual-mode chip. In terms of resolution, CIF/D1 is currently the mainstream resolution. Due to the further development of video compression technology, storage capacity and transmission bandwidth, high-definition surveillance applications have entered the high-end fields such as banking and banking.
(B) Intelligent
Intelligent video surveillance is a high-end monitoring technology with powerful processing capabilities developed on the basis of digital networking. It uses pattern recognition algorithms to identify object categories, analyze object activities, remove unwanted information, and provide information without manual intervention. Routing to the correct node can even detect abnormal conditions in the monitoring screen and issue an alarm in time. In addition to powerful processing power and video processing algorithms (such as compression, networking, and other control functions), the processor must be able to process intelligent algorithms in real time, which requires a special processor architecture.
Intelligent typical applications include abandoned object alarms, face recognition, automatic patrols, and entrance and exit statistics;
For example, in areas such as banking, ATM face capture, face recognition and alarm functions are particularly important; for example, highways, toll stations, bayonet, can carry out vehicle license plate recognition, traffic statistics, speeding capture, etc.; for example, airports, stations, etc. The face recognition cooperates with the central database to analyze and process suspicious faces, support the face picture video retrieval function, restricted zone management, etc.; for example, forest fire prevention, fire and fire analysis, and fire warning. This series of intelligent industrial applications will increase users' safety protection factor and prevention efficiency, and bring more convenience to people's lives and safety.
(III) Mobilization
Mobile security is a professional-grade monitoring product combining mobile communication software and traditional security. It integrates mobile communication, security and the Internet, and transforms system integration technology into potential product applications. As a new technology and product in the field, the logistics network and mobile video surveillance system rely on the technical and IP network's seamless compatibility and the provided remote real-time video processing capabilities. The annual growth rate of the Chinese market is 20%, and it is rapid. Become one of the fastest-growing products in the market and keep pace with analog monitoring systems that have been operating for many years.
The popularity of 3G networks will accelerate the mobile security business to a new era, a new era of remote video surveillance with mobile phones, an era that will introduce monitoring concepts into the home, such as: mobile TV services, mobile video telephony, mobile remote monitoring , mobile phone navigation and so on. Mobile security has great potential in the public sector such as *,*, firefighting, civil air defense, flood prevention, and forest fire prevention. It can transmit a large number of on-site situations to various departments of the management center in real time, without using the high cost of satellite communications. This will not only contribute to creating a safe city and a harmonious society, but also provide jobs and drive economic development.
