IP network monitoring is the trend of future video surveillance

The high-speed ball in the digital era relied on the gradual improvement of the market's demand for high-quality image quality, forming a trend of contending and making progress together. HD-SDI and high-definition networks, also known as high-definition digital, have given two different flavors. The emerging HD-SDI has rapidly emerged with its advantages of uncompressed and high security frames. With the increasing popularity of the Internet today, the network dome reflects its overall convenient solution and is highly sought after by all parties.

As HD-SDI technology becomes more and more mature today, it can no longer meet the needs of the market with no compression and high security frames. SDI matrix, SDI hard disk video recorders, and SDI optical transceivers have emerged and expanded so that SDI gradually replaces the analog position. . However, due to the limitations of the transmission mode, SDI video surveillance has been limited in the transmission distance, making some short-distance projects take a futile expenditure on HD-SDI. The SDI high-speed ball also inherits the various functions of the traditional analog dome camera. It can be said that the HD-SDI high-speed dome is a fusion of the HD-SDI technology and the traditional analog dome camera. The HD is still familiar behind.

When it comes to HD-SDI, we must also mention high-definition networks. Some people say that network domes have large delays, coding and decoding losses, and high bandwidth. They have not been well resolved, and the development of network monitoring has been slow. In actual fact, the network ball machine bid farewell to the traditional ball machine 485 keyboard control style, using the client real-time picture control. At present, most of the network high-speed domes on the market use H.264 or MPEG-4 high compression ratio algorithms, which can achieve high picture quality and low bitstream capabilities, and greatly improve the network transmission speed. With the development of digital, network, and intelligent technologies, video surveillance has gradually developed toward the "three directions." From large cities to safe cities, to individual homes, they are all quickly compatible. With the rise of IP surveillance, the demand for high-speed networks for networking has increased. The network high-speed ball is an important branch of the current development of the high-speed ball. Based on the current high-speed ball, adding an image or voice encoding module and a network access module can form a basic network-type high-speed ball to realize video and audio data. Control the smooth and reliable transmission of data over the network. For the user, network monitoring is not limited by time and place. In the case of authorization, it can be monitored on demand at any time, and plug-and-play can be achieved. The use is very convenient.

As a result, IP network monitoring was consistently considered by the industry to be the main trend of future video network monitoring. However, its soft underbelly has not undergone a qualitative change after a period of time. It does not mention the common problem of delay and frame dropping. Even the code is used by different manufacturers to use different protocols according to their own situation, resulting in back-end and large-scale. There is a lot of unnecessary trouble with project compatibility. At this time, the emergence of HD-SDI solved these problems. It made people see hope again. Between gains and losses, the value has not been measured by analog designers. At present, IP networks have also made great progress in quality management. As the country attaches importance to network construction and network technologies are constantly updated, better broadband networks will be used. On the other hand, in order to solve the problem of network bandwidth, related companies are also constantly introducing new networking solutions, making the IP network monitoring technology constantly improving.

The advantages and broad prospects of network monitoring have prompted domestic and foreign security companies to develop products suitable for network monitoring. Due to the adoption of advanced digital compression technology, these network products can reduce the transmission bandwidth and storage requirements to compensate for the defects caused by insufficient network bandwidth. The emergence of network high-speed ball is the inevitable outcome of the development of digital monitoring. The use of convenient and fast network technology to transmit video and control signals will greatly expand the application of high-speed ball in the monitoring industry, especially in urban monitoring, highways and other places. With the development of technology, 3 million pixel cameras will also be born. How the HD-SDI dome solves its own bandwidth problem will be a problem that has been discussed since then, and the network dome camera should be able to quickly adapt to the market by virtue of its continuous compression technology enhancement. Once there was a strategic policy of "encircling the cities from the countryside," and proceeding from the national conditions, it won. Today, there are so many groups that have been forgotten. When the community and the new rural monitoring era come, who will be the world?

There may be doubts about whether the night vision effect of the high-definition dome camera will be inferior to that of a traditional analog dome camera when night falls and darkness is overshadowed. On the contrary, with the enhancement of the function of the movement, the promotion of low illumination and the cooperation of the infrared lamp group, the high-speed ball is more competitive. Imagine that you could not observe the scene of two hundred meters in the night without reaching out, and it is not just a figure. With such high level of integration and rich functionality, such a product will be used in a large market.

Nowadays, domestic high-speed ball technology, although the movement still relies on the support of foreign brands, but over time, the inspirational development of the Chinese people has gradually narrowed the gap in this regard, and in the future framework, the domestic movement The share will gradually exceed Sony, Hitachi and other foreigners.

The huge market demand in China has affected the development of the security industry at an alarming rate. The domestic industry leaders have gradually narrowed the gap with foreign industry giants, and some small and medium-sized enterprises with core technologies have gradually gained a firm foothold. In the surveillance boom of “Safe City” and “Safe Town”, high-speed domes are strong and account for more than 60% of the front-end equipment. With domestic manufacturers gradually mastering the core technology of high-speed domes, independent research and development of high-speed domes The machine has become a powerful force in the market with its higher cost-performance advantage. More and more people are beginning to accept this high-end surveillance product. In some remote mountain areas and small townships, high-speed dome cameras are also common.

With the gradual improvement of functions, the gradual increase of market demand, the progressive improvement of living standards, digital high-speed ball will be more widely used, high-speed ball will have a beautiful tomorrow.
