HD technology is maturing

Everything is good or bad network monitoring system, the focus is on the image of the customer's eyes are good or bad, HD is the user's eternal pursuit. At present, many users do not know what the Internet HD is like and what they are, so they do not have the concept of HD. Once the effect of high-definition system is perceived and recognized by the user, users will quickly launch applications under the influence of the policy city, and even form a large replacement opportunity for the market of security monitoring equipment.

HD monitoring basics HD network cameras provide the source for video surveillance. It has video-encoded and IP-encapsulated, and carries high-definition images over IP networks, enabling surveillance functions such as high-definition surveillance and video recording.

At the sending end, the network camera integrates the image acquisition, video compression coding, communication control and transmission interfaces, and the video data is output through the IP network.

In the image acquisition part, CCD and CMOS sensors are designed for different needs. CMOS has certain advantages in terms of high pixels, while CCD is more adaptable to monitoring scenarios. In the video compression coding section, different compression algorithms and algorithm implementation schemes determine the quality and coding efficiency of high-definition images. In the communication control part, the network's adaptability, security, code stream encapsulation format, and transmission capabilities depend on the planning and design of the monitoring system. In the transmission interface part, different network access methods, such as wireless and wired, can be well supported; in addition, some network cameras also integrate other interfaces required for monitoring, such as alarm, control, intercom, and other interfaces.

At the receiving end, it decodes and outputs it to high-definition display devices, such as LCDs, and records high-definition images through recording devices.

Due to the high bit rate of high-definition images, which is generally more than 3Mbps, image recording is an important part of achieving high-definition recording. To record HD webcam images, we can use the following methods:

PC-NVR

Embedded NVR

Hybrid DVR

Whichever method is used, the following requirements should be met, such as:

Guarantee video storage period, need enough storage space;

Ensure the validity of multiple concurrent records, that is, there should be no bottleneck in the recording process;

Convenient and quick retrieval and playback efficiency

With cycle coverage, multiple coverage should ensure the efficiency of recording and retrieval;

Reliability, cost-effectiveness should meet the monitoring business requirements.

PC-NVR utilizes the PC-DVR development technology and can perform secondary development through the SDK provided by the HD network camera. The storage technology can be DAS, NAS, IPSAN, etc.

High-definition technology is maturing as an end user. To be sure, which industries are in urgent need of high-definition video, which industries may become the leading market for high-definition surveillance, users of these industries will become the first object of high-definition network monitoring. At present, users of banks, transportation, hospitals, and other industries have already built or have built HD network monitoring systems of different sizes. These applications show that HD network monitoring has started the market.

When the monitoring system has gone through several historical stages of analogization, digitization, networking, and intelligence, since 2008, high-definition surveillance has become a new application demand highlight with the deployment of network monitoring, and it has relied on users forever. HD is in full swing.

For example, an analog camera product was once called a high-definition camera at 480 lines, and now 540 lines or 580 lines have replaced 480 lines as representative of an analog high-definition camera. After the brief experience of the network camera, represented by D1, the terms megapixel, 1.3 megapixel, 720P, 1080I, and 1080P have already begun to be embedded in the terms of HD network cameras.

DVR initially emphasized encoding and decoding technologies from MPEG2, MJPEG, MPEG4, H.264, etc. Basically, no one emphasized the terms CIF, QCIF, DCIF, and D1. In the first three years, the term D1 became a popular symbol of DVR HD. At present, some companies point out that the quality of CIF is similar to that of D1. At present, after the DVR is fully equipped with products such as the D1 HD, a hybrid DVR that supports megapixels has emerged, and even more companies plan to simply call DVRs that support megapixels instead of DVRs and want to change their name to PDVR.

The evolution of these technical parameters reflects the continuous improvement of the picture quality of the image. When the technology becomes the leading state at that time, the picture is high-definition. The development history of the monitoring industry shows that HD is the historical stage of the development of image processing technology. It defines the mature technologies and image effects of the period. Therefore, every time monitoring image technology is upgraded to a new high-definition platform, it represents the era. HD monitoring terminology will become the new high-definition synonym.

At present, the market for high-definition network surveillance on China's security market is still basically in the initial stage. The sales of various chip vendors, product vendors, system integrators, and system platform vendors in the network high-definition surveillance market are still in the test phase because Technology and systems are still in a constant phase of perfection. From the realistic and mature application of market efficiency analysis, the high-definition network monitoring industry chain companies are still focusing on traditional products and systems, network HD, is the next battlefield. Because of this reality, all the core companies are currently preparing for high-definition, but everyone is still lazy jogging on the starting line and looking around.

However, some core high-end industry application markets are quietly stimulating the growth of this market. Whoever has good strategic planning and implementation in product technology, or system solutions, and market operations, the Chinese HD surveillance market will New high-end companies will emerge.

In the pursuit of this round of high-definition network monitoring, the favorable demand environment for the application of new products and new systems in the Chinese domestic market will be able to effectively promote the growth of Chinese and foreign security companies in the Chinese market. Of course, this impetus is limited to those companies that have core technological development capabilities. Judging from the starting point of development, China’s domestic security companies with certain technical strengths are, to a certain extent, not far from the technological starting points of overseas security companies. This may lead to the development of local enterprises in the high-definition monitoring field. Therefore, the evolution of the network HD surveillance in the Chinese market is likely to have a surging situation.
