In 2011, Internet-related management agencies stated that with the advent of smartphones, connected appliances, and even connected cars, the global IP address used to identify digital communication destinations is about to run out. Once this information was disclosed, many authoritative scientists and regulators also expressed their position that the IPv4 address has been exhausted and that there is no available address in the world. With the continuous development and expansion of the network scale, new protocols have also been born. The emergence of IPv6 has neatly solved the flaws of IP address advisories. In fact, the transition from the IPv4 to IPv6 protocol has been initiated worldwide. It is reported that the 24 hours starting at 0:01 GMT on June 8, 2011 will be the first trial day of the IPv6 protocol system.
IPv6 has a much larger address space than IPv4, with 2 128 (about 3.4x10 38th) addresses, which is calculated by a population of 7 billion people on earth, and almost everyone gets an average of 4.86x10. The power of the IPv6 address can fully meet the network monitoring and video communication application system's demand for IP addresses. Therefore, on the eve of the impending exhaustion of IP address resources, network monitoring companies should strengthen research and development to enable their own network monitoring equipment to support IPv6 as soon as possible so as to thoroughly resolve the shortage of IP addresses. At present, many domestic enterprises have already achieved support for IPv6, and IT companies such as China Telecom and Huawei have made progress. It is understood that in the field of security, its communications companies represented by Warburg shares have also begun production of full-line products to support the IPv6 protocol, and also the application of IPv6 support for conversation between any device. Video conferencing systems and high-definition IP cameras all require network support. With a good network infrastructure, high-definition monitoring can be achieved without any remote accessibility. Network monitoring has been highly praised for its many advantages such as simple installation and maintenance, convenient management, and wide application. In recent years, the market share has greatly increased and it has become the trend of monitoring the market. The birth of the IPv6 protocol also ruled out the worries of network monitoring. However, due to its own factors, the development of network monitoring is still hampered and faces the following problems:
1. The price of the front-end network camera is too high, affecting the price/performance ratio Currently, the equivalently configured network high-speed ball is about 50% higher than the analog high-speed ball, which makes the network monitoring face the high price of the front-end price. When the monitoring system is built, compared with the simulation system, the price/performance advantage is not obvious. The small and medium-sized monitoring system is the stronghold of analog monitoring. Therefore, if the price of the network camera is too high, the replacement speed of the network monitoring system for analog monitoring will be reduced.
2, the dependence on the network is too strong Network video surveillance has a strong dependence on the network, huge data and signal traffic and the current relatively small available bandwidth is a contradiction, which is also the basic network monitoring system is large and medium-sized Reasons for construction based on local area network or government-industry network. Moreover, network monitoring also has problems such as poor image quality, slow network speed, transmission delay, and network security due to network transmission. Until now, these problems have not had a good solution. Therefore, people have many doubts about the application of IP network video surveillance.
3, bottlenecks in high-definition applications Although high-definition and network, intelligence is recognized as the three major trends in video surveillance, but in recent years video monitoring market, the real application of complete high-definition video monitoring is very small. The reason is that bandwidth and storage bottleneck are the two major factors. HD video with 720P as the starting point has high resolution, and the huge HD data stream is more than 10 times that of CIF. The HD video stream will reach 4-10M. Too much, this is an unacceptable burden on the current network conditions.
When the traditional network encounters development bottlenecks, many people in the industry place their hopes on another type of transmission medium fiber, but domestic fiber-to-the-home systems are still in the pilot phase. In Shanghai, Beijing, and Shenzhen, there are still no popular cases. Real implementation is still a distant matter. Of course, there is no other way to increase the bandwidth capacity. In fact, we can also improve the vitality of high-definition video by reducing the high-definition video stream. H. The birth of the video codec technology represented by 264HighProfile can halve the video bandwidth of the same quality, and can achieve 720P full-motion HD video transmission with only 512K of bandwidth. It can be said that the application of high-definition video has broadened the road.
