2009 video monitor: networking and promotion of several major trends (1)

Combined with a number of research institutions report, a more credible data show that in 2007, the gross output value of China's security market has reached $ 1450, which accounted for 47% of the security products (682 billion), accounting for 53% of the Security Engineering (769 million).

In the security products, solid protection products accounted for 33% (225 million), electronic security products accounted for 67 per cent ($ 457). Electronic security products which we have always said that the special protection, including video surveillance, building intercom and access control, intrusion alarm 4 categories. In 2007, 457 million of electronic security products, video surveillance accounted for 58 per cent (265 billion), while building intercom and access control, intrusion alarm accounted for 13 per cent respectively (59 million), 14 per cent (64 billion), 15% (68 million).

In other words, in the narrow security market video monitoring in occupies the position of the absolute main.

Furthermore, depending on market growth in recent years, the share of the video surveillance was further expanded. In recent years, China security market CAGR basic maintained at 20 percent, while the video surveillance of the CAGR is in excess of 25 per cent.

For video surveillance with such a fast growing market, in recent years is showing a kind of trend, then what happens?

Networking: no longer a trend, has arrived

From the initial suspicion, later the unanimous endorsement of the, on the network is the trend of the discussion has been going on for nearly 5 years.

Now, it should be that it's time: networking is no longer a trend, networking has really got us — networking has arrived.

From market data, 2004 to 2007, analog monitor accounts for video monitoring of share from 56.9% 19.7% digital monitor accounts for video surveillance of share from 35.7% growth to 54.4%, network monitor accounts for video monitoring of share from 7.4% growth to 25.9%.

That is, traditional analog monitor accounts for more than a pitiful already obvious, although to DVR digital monitor represented in occupies more than increased, while its share of CAGR only 11 per cent, and network monitoring account than CAGR reached 37 per cent. In 2008, based on the popularity of network monitoring and accounting of accelerated growth rates than the yearly projections estimated network video monitoring covers the entire video surveillance ratio may reach 40 per cent, close to the proportion of digital control.

Application from the industry, the video surveillance market for major industries are obviously tended to give priority to select the network monitor.

Based on our own in the 2008 survey done by the end of the year, video monitoring current main markets are concentrated in government public security, finance, industrial enterprises, building community, education, transportation, and several other major industries. In our contacts with government agencies and public security "safe city" project, 70 per cent made it clear that you want to select the network monitor, 20 per cent to test assessment and decision. Financial and transport industry in recent years showed a clear big networking needs, in a simulation of the monitoring and surveillance of the pain and the experience to do a network monitoring and ease of surprise, the network is no doubt that has become the primary choice. Education industry because the network infrastructure improvement without exception of obvious preference for network monitoring. Industrial enterprises and building community more dispersed, independent, industry features less obvious, weak product independent selective, so the tendency is not above several industry less noticeable, but because of network concepts in the Integrator, engineering and Design Institute of the link already widely recognized, so the vast majority of new system optimization and network monitoring.

From the network environment, today's networks is fully equipped for video transmission, and video communications requirements, all accredited degree unthreatened.

We initially on network monitoring main concern focused on network bandwidth, network delay, network stability, network security, these four areas. Now let's take a look at these aspects.

First, the network bandwidth.

The LAN connection, now generally is 100Mbps, 1000Mbps, even and data communication sharing, transmission for localized control is sufficient. Internet (Internet), we now every day through its online viewing high definition movie (300Kbps ~ 1Mbps), every day through its online video chat with friends (dozens Kbps ~ several hundred Kbps), image stabilization, smooth, its end-to-end bandwidth can meet today MPEG-4, H.264 and other high performance encoding of remote monitoring transport demand. Also, the more convincing that already have more and more video conferencing will run on the Internet, video-conference on network bandwidth requirements should be more stringent than video surveillance.

Second, network delay.

Because of the need to carry out interactive communication, video conference on network latency requirement is very high, coupled with coding and transmission, one-way delay is generally not exceed 250ms. Today's Internet time delay has been able to meet the needs of real-time video conference, so also fully able to meet the needs of real-time video monitor.

The third is the network stability.

Network stability measurement basis is a network interruption time during the year, due to the telephone network is fully satisfied the carrier-grade standards, so we can use the telephone as a reference, for a variety of network processing technology and the stability of the technical development, today's local area network stability has been comparable to the telephone network stability, the stability of the Internet is close to the telephone network stability. Moreover, network video monitoring itself on the stability of the technologies, is to eliminate network stability on its effects, including key equipment and parts of hot backup, media, load balancing, front and Center to store backups, and so on.
