Panoramic visual system

Video monitoring system development experience different from imitation to digital era, its video understand degree also got always improve accordingly. Imitation as the CCD always development, video monitoring and digital video monitoring and understand degree in longitudinal, imitate the camera level rate from 380 to 380 respectively, pixel digital camera development from 250000 to 16 million. In the era of imitation, the camera level rate respectively were considered as long as more than 480 lines, can be called a high-definition video camera; And about the digital camera, respectively rate reached more than 720 p talent is called the high-definition cameras.

China's security industry since "million pixels" concept proposed in 2006, in view of the user requirements always change, each big manufacturer in different stages of technology development has launched different hd monitor solution, summarise it, generally can be divided into three generations.

The first generation of hd - panoramic video surveillance system

Digital monitoring products process accelerated in 2000, the industry of "digital, networked, intelligent monitoring technology development trend, a step by step, but the network camera is always because of picture quality, delay, cost and other factors difficult to or absorbed by the market, until 2006, when the first generation of high-definition monitor system, the situation didn't change.

Important by the first generation hd monitor system, "millions of pixels of cameras and video management software, practical in medium and small range of situations. Imitation compared with traditional monitoring system, the first generation of high-definition monitor system image more clear, broader, more than similar supervision area can replace the original fixed point camera or omni-directional camera. It about need multiple lower rate respectively the camera designed for maintenance occasions corner, can directly reduce the installation, maintenance and application.

Though have more advantage, but the first generation of high-definition monitor system is aimed at development of small and medium-sized monitoring situations, most can only access to dozens of hd video, or in the transport, storage, display, control coherent links such as emerging problems, couldn't satisfied safe city and other large at thousands of road video access requirements, monitoring and control system of medium and small range of situations, although the image quality has improved, but the first generation of high-definition monitor system of capital is too high. Therefore, the first generation of high-definition monitor system in the domestic market has always been hard to turn the situation. Though the early marketing is not absorbed by the market, to a wide range of applications, but the launch of the first generation hd monitoring system, for "hd monitor" laid a good foundation, promotes the industry attention about "hd monitor", for the vigorous development of the subsequent "hd monitor" played an indelible role.

The second generation hd - panoramic video surveillance system

Second generation hd monitor system is arises at the historic moment, it is important from the hd IPC, hd codec, Gao Qingguang machine, NVR, IPSAN equipment composition and so on.

In 2009, the ministry of public security has been released on the image to understand put forward higher requirements of the "red light automatic record system general technical conditions", the road vehicle intelligent monitoring record system general technical conditions ", the path transportation security illegal action image forensics technology scale, the scale of motor vehicle plate image automatic identification technology and a series of scales. In December, public security department of jiangsu province launched "320" items, the items planning within jiangsu province to build a path monitoring network, the path every 3 km away from across the province to create a snapshot of vehicle monitoring points, the path of other monitoring every 20 km to set up a capture point, the names will invest 9 front-end equipment. More than 5.4 billion, total investment of nearly 2 billion kinds.

The names in the equipment for phase, the front end cameras made a minimum of 2 million pixels, news, provoked uproar in the industry, major monitoring are introduced in view of the public security demand of all kinds of hd monitor solution, after a period of consolidation, fulfillment, gradually formed the demand can be satisfied with large monitoring system of the second generation of hd monitor system.

The second generation hd monitor system from the first generation of hd monitor system has the following advantages:

1, the second generation hd monitor system consists of hd IP camera, transmission, display and storage of all links such as equipment, each link of the equipment is aimed at a large monitor and control system development, system function more comprehensive, more stable performance;

2, the second generation hd monitor system can supply 720 p hd video image or above, and understand degree increased more than double;

3, the second generation hd monitor product based on network monitoring, can form a wide range of monitoring and control system;

4, the second generation hd monitor system can through the visualization platform management software management.

Second generation brought unprecedented high-definition high-definition monitor system for the user experience, direct stimulation of the demand of the market, in 2010, security monitoring items and electronic police around the nominal began to take the second generation of high-definition monitor system, a wide range of high-definition monitor market began to enter into high speed development stage, as a result, the industry will be referred to as "high definition" of the first year of this year.

The third generation of hd - panoramic video surveillance system

Nearly two years, the second generation HD monitor system into high speed development stage, then also naked across a wide range of market applications show image damage, delay and so on a series of problems cannot solved in the short term, and thus promoted the hd-sdi technology application in surveillance industry.

People found in the application process of various systems, whether the original copy monitoring system, the second generation of HD or hd-sdi, have irregular people give up place. Original copy monitoring system has not yet arrived in the application of fixed number of year, many outlets still practical, all change for hd, investment not only grand, will also face the danger of grand decisions. Second generation hd system has roots can satisfied user's needs, but when access the original imitation system, after decoding image quality decreased obviously, not only for PTZ tracking procedures, around 400 ms delay more made it difficult for users to absorb.

Hd-sdi despite good realized image real-time, nondestructive, but because is compressed video, if large range setting, on the network and storage pressure will be very grand. So can be real-time, nondestructive imitation access monitoring and control system, and according to the actual user needs setting HD IP and hd-sdi VAR3S monitory point of third generation high definition monitor system was born.

VAR3S third generation HD monitor system, not only is to realize the hd-sdi, IP high-definition, standard definition video access can, but to truly understand the three kinds of systems, set hd-sdi digital video compression and H. 264 digital video compression at an organic whole, to the satisfaction of both high definition, high requirements of real-time image, and to the satisfaction of digital storage, IP network transmission requirements; Both can front-end coding, and can concentrate sub-center present center compression coding, truly realize the hd-sdi HD video, IP HD video and imitates video do their networking, scheduling, switching, control, support for video, audio, data, Ethernet, E1 signal, switch etc all kinds of signals, access, and can solve the problem of more business on the same platform and at the same time access.

It can be understand that third generation hd monitor system can be in accordance with customer demand customized, combining their respective advantages, starts its monitoring system features the latest generation of monitoring system.
