Low-cost high-definition monitor will go further with intelligent

According IHSiSuppli’s latest Chinese research report predicts that in 2012 Chinese video surveillance market growth rate of about 13.9%, total revenue will reach $ 8.7 billion, of which high-definition surveillance products have become the domestic security industry continues to move forward a big help Power, also marks the video surveillance market is entering the “HD era.” HD video surveillance industry standard primary or follow the broadcasting industry standard, that resolution of 720P or 1080p. From an implementation point of view means, clarity can be achieved 720P or 1080P HD surveillance technology program has the following two: one is high-definition IP network monitoring system, the other is HD-SDI HD surveillance system. From a practical application point of view, the application of the higher cost of the latter, and by the transmission system and storage system constraints, overall, network monitoring system accounted for the vast majority of current high-definition applications market ratio, and to 1.3 million end pixel-based (approximately 60%). Although in recent years the pace of development of network monitoring for all to see, but with a more mature market compared to traditional analog, had to admit that it is still in the stage of steady growth. According to industry research firm’s statistics, in 2012 the overall network monitoring video surveillance market accounted for about 30%, but the growth rate, network monitoring is expected to last several years the average annual growth rate of about 15%, slightly higher than the overall video surveillance market growth rate. From the “visible” to “see clearly”, high definition video surveillance security industry set off a new round of reform through digitization and networking technologies. This will have an impact not only on the front of the camera, speaking from the entire security industry chain, including sensitive device CCD, chip processing technology, the transmission system, so that the back-end storage devices, monitors, etc., will usher in a large technical leap, the next phase will also lay the foundation for the development of intelligence. Along with high-definition monitor process, requiring manufacturers have a stronger core technology research and development capabilities, and the ability to combine the unique needs of the project, the user presents a more perfect visual effects and application experience, thus speeding up network HD surveillance system penetration.

In the past, high-definition IP cameras and HD hinder network monitoring large-scale use there are two main factors, the first is the limited network bandwidth and storage capacity is too large, and the second is the more expensive HD ip camera. As technology advances, these two factors are gradually eliminated. First, communication technology and coding technology, has made limited network bandwidth, storage costs are too high and gradually become history. In megapixels HD 720P calculations, mainstream manufacturers using H.264 encoding process, you need the bandwidth is about 2-4Mbps (1080P is a 4-8Mbps). For the end user is concerned, bandwidth is not a problem. For video surveillance transmission network in terms of the peace of the city in the current financial network monitoring and other projects, it has been widely used in construction of fiber-optic networks to achieve 1000M bandwidth networks, can effectively support the practical application of HD ip camera. HD monitor storage costs, not as imagined so high. Previous memory contents, only used locally, and now the memory contents, you can use the network, from the use of cost-efficiency and user terms, is much lower than digital surveillance era. Coding compression technology continues to advance, H.265 standards will promote a higher compression ratio. With H.265 increasingly mature industry chain, will further accelerate the era of large-scale arrival of networked security definition process. Secondly, in terms of overall cost, high-definition network monitoring systems, especially the new system, compared to semi-analog half digital monitoring system, the comprehensive advantages are gradually emerging. With the involvement of a large number of manufacturers, digital high-definition camcorder prices will gradually decline. Deploy a high definition network surveillance system required number of cameras to be greatly reduced. As high-definition network surveillance system architecture is simple, will be supporting the wire, transmission equipment, back-end equipment, as well as other aspects of construction and maintenance, the cost should be lower than analog systems, but also flexible and convenient construction.
Security monitoring from the past “visible” to the current “see clearly”, thanks to the digital one million high-definition video surveillance technology, the rapid development of intelligent high-definition monitor for the future and lay a good foundation. With high-definition monitor new technologies, new products continue to emerge, “HD smart” video surveillance applications development trend has become the consensus of many people in the industry. In recent years, frequent natural disasters, mining accidents, traffic accidents, medical malpractice, food safety, emergency, etc. These effects of social and public safety incidents, the government, society and the public high concern. These problems but also to the security monitoring proposed new requirements, high-definition monitor intelligent growing. Currently the main role is to monitor HD video surveillance scene by human duty monitor screen situation, security incidents, you need to call a large number of video playback to locate, track or trail crime scene at that time, heavy task, work volume. Besides human duty drawbacks is more, not only the work of monotony, and easily cause visual fatigue, ignoring screen monitors make mistakes. HD ip camera implanted in the intelligence function, through intelligent analysis, high-definition monitor screen to identify the persons or things in the scene, contrast, judgments, and to prompt the user to produce abnormal or alarm. Such as face recognition, cross-border actions, illegal invasion, flow calculation, relics recognition. Most of the current video surveillance only play recorded video, the playback after the accident inquiry role changed to proactively identify, alarm, truly trouble.
