How far is the HD market?

In the current security industry, high-definition has already led the development trend of the mainstream. However, in a sense, high-definition is not limited to front-end devices, but also consider the storage devices of the back-end, in other words, the cost of high-definition systems. It is no longer a question of the price of a single device, but a set of system problems. The current high-definition price has fallen sharply compared with several years ago. Although it cannot be predicted that there will be such a trend in the future, the application of high-definition will become more and more popular. The high-definition monitoring will certainly take the civilian route.

The standard for measuring the sharpness of the HD monitor is the resolution, and the unit is the pixel. The larger this value, the clearer the image. The so-called HD, SD, the difference is also reflected here. The dividing line between the two is megapixels or 720p, reaching megapixels or 720p is HD. Based on such standards, CIF and D1, which currently dominate the video surveillance market, are standard definition.

Whether it is from the perspective of resolution, display effect or fluency, HD has more advantages than SD. In terms of resolution, the 720p resolution is 9 times the CIF resolution, and the 1080i/1080p resolution is 20 times the CIF resolution. In the same display environment, HD will be much clearer. From the display effect, HD supports both large-screen display and 16:9 wide-screen display, which can greatly enhance the user's viewing experience. In terms of fluency, HD supports higher frame rates. For example, both 720p and 1080i/1080p can support 60 frames per second or 60 fields per second, and image fluency is twice as high as standard definition.

Therefore, the replacement of SD by HD is the inevitable trend of video surveillance.

Benefits of High-Definition Image Quality With the rise of intellectual property rights and the increasing demand for high image quality and enhanced customers, the demand for high resolution is increasing. The introduction of a 2-megapixel camera has driven the latest high-definition innovations, including improved image quality. Considering that the monitoring images of a few years ago have caused people's images to appear distorted, they can often only recognize their outlines. What is different from the past is that users can now clearly recognize very small numbers and characters.

HD cameras can be up to 4 megapixels from about 1.3 million pixels. Increased visibility also dynamically optimizes the brightness of each pixel of the image. When the area is dark or too light, the extended visibility of visibility enhances the shadows. Instead, it means that the clear, bright image is displayed under very low light conditions. Visibility also helps to enhance the camera's sensitivity and crimes that occur at night statistics. Appropriate video security techniques can significantly reduce crime.

Having a security surveillance camera will greatly change the brightness and clarity of the image. HD is able to achieve both of these aspects that help create a more secure surveillance system that has been developed for businesses and public places. Taking into account the 9.11 and London bombings, a security HD video surveillance camera is very necessary.

Regarding the future, excellent dynamic noise reduction (XDNR) provides the latest developments in the IP CCTV network with clear images of professional moving objects and still images in low light conditions. This will increase security. On the one hand, application in the parking lot can reduce theft. The other has become a part of many consumers watching fun - three-dimensional technology.

Recalling the past, a high-definition video surveillance **, from 2 million pixels to the current high-definition. Consumers have already seen the development trend of home HD technology, and as a result, people are more easily understandable, such as 720p and 1080p, full HD specifications. In today's society, there is a great need for a better security and innovative solutions to lead the development of high-definition.

The problems that need to be overcome in order to successfully obtain high-definition HD 1. The cameras used for monitoring the working environment may be installed outdoors in a climate with extreme weather, or in a hot and humid room, whether it be cold or hot or cold, and monitoring. The camera must be able to operate normally all the time.

2. Cameras for camera environment monitoring must be able to clearly record each frame of video under a variety of different scenes and dramatic lighting changes. Whether it is in the dark, a scene of an explosion, or someone in a dark alley deliberately using a flashlight to shoot a camera lens, it can capture the process of the incident.

3. Video Capture Because intelligent video surveillance systems must rely on correct and clear images in order to function intelligently. If a gray dress is photographed as a white dress in a bright light, or a skin-white face is made into a deep skin tone in a dark corner, or a fast-moving person is made into a distortion-distorting object, it will let Intelligent identification systems cannot accurately identify the target person or thing. Clearly recording each frame in high resolution is an essential element of an intelligent monitoring system.

4. Video Compression A video surveillance system often includes dozens to hundreds of cameras. Once a high-definition camera is used, the total video information increases dramatically. This poses great difficulties for video transmission and wiring. Only in the case of no loss of picture quality within the camera, highly compressed video signals can significantly reduce the transmission requirements and costs of high-definition video signals, and transmit high-definition video signals via wireless or wired networks.

How far is the high-definition market in the end from the current domestic security HD status, in addition to the above four difficulties, there are still many problems to be resolved. First of all, the technical problems, many key issues still need to be solved, such as the constraints of network bandwidth, such as high storage products, such as the need for the development of control management software and hardware, for hundreds of roads, thousands of roads to the high-definition monitoring project It is said that these are problems that need to be solved.

In addition, from the user's perspective, the current market is not mature, the high cost of high-definition monitoring does not meet the requirements of the general security market, people are more inclined to use network video surveillance, or even digital-analog hybrid systems, after all, the cost of the entire security project for China For the security market, it is still quite high.

There are currently two major factors that restrict the development of high-definition. The first is that manufacturers, middlemen, engineering companies, and users recognize the concept of high-definition, and only after high-definition is universally recognized can the high-definition market be possible. Second, the cost of HD. Compared with the cost of the SD monitoring system at the present stage, the cost of the HD monitoring system will undoubtedly increase greatly. If users are accustomed to the current cost structure, they can accept a new cost structure that is many times higher than the current price. For users, this will be a big challenge.

However, the challenge will not be repulsed. Although the current high-definition market is confusing, the immaturity of technology, and the immaturity of the market have brought great difficulties for high-definition applications, but the opportunity for high-definition market is rare, the time is ripe, the key Still look at the technical strength of HD manufacturers.

For video surveillance, image clarity is undoubtedly the most critical feature. The clearer the image, the more obvious the details, the better the viewing experience, and the higher the accuracy of application services such as smart, so image clarity is the eternal pursuit of video surveillance. Whether it is from the perspective of resolution, display effect or fluency, HD has more advantages than SD. Although analog monitoring still occupies an absolute share in the market, the market share of digital surveillance in recent years is also increasing exponentially. There is a great trend of substitution. When the standard digital surveillance is accepted by the market, HD is not far behind. Now.

Intelligence promotes HD to "use"

HD can not only stay in the resolution size, but should be combined with human visual effects, while focusing on the stability and practicality of HD products. HD is not only about resolution, but only HD has been further applied to reflect its own value.

High-definition brings not only the resolution improvement, but also the emergence of high-definition, there will be many applications that could not be realized in the SD system (for example, combined with intelligence). This is a qualitative change. Therefore, high-definition will bring about changes in the application, and it will bring about changes in the technology defense model.

HD and smart should belong to an advanced stage of video surveillance, and the two complement each other. With intelligence, it is possible to further extract effective information for high-precision coding and reduce the occupation of bandwidth-invalid information. Because of the demand for high-definition, it can bring urgency to smart demand. To make the network video surveillance system intelligent, its most important product form should be the intelligent front-end network camera. High-definition video technology can bring us high-quality video sources with rich and complete information with high definition and no delay. Analytical technology can bring us diverse applications through intelligent information. Without high-quality video sources, video intelligence analysis will greatly reduce the accuracy due to the problem of video resolution. Because of scene problems, the amount of information will be greatly reduced. On the contrary, without video intelligence analysis, high-definition video applications will only stop at 'seeing. 'The initial stage, but did not rise to the 'use' advanced stage.

Smart can remove the redundant information collected by the front end. In the case of improving the resolution of the captured image, intelligence can help analyze subtle goals. From this perspective, HD is not predicated on intelligence, but HD helps intelligence. Analysis of development.

The combination of high-definition and smart is a must, and the combination of high-definition and smart will bring changes to the video surveillance application model. High-definition has left the intelligence, and the resulting value is merely an increase in resolution. For smarts, many smart technologies and applications are only practical on a high-definition basis. Therefore, the large-scale development and application of intelligence should be based on high-definition. In essence, HD only provides the content of video data. Intelligence is the first use and consumption of content, and generates secondary data and content at the same time. The broader application of high-definition and smart is based on this data mining, through data mining, will produce a variety of application solutions in various industries, this will have a huge and far-reaching impact on the entire security, IT industry chain .
