High-definition monitoring technology core and internal architecture applications to get rid of fuzzy interface

Since 2010, the concept of high-definition has been recognized by people since the World Expo and the Expo. From the monitoring era of various security equipment applications to the visual quality of the front end of the display, they all mark the stage of HD walking in urban life.

When the high-definition era was under surveillance, it was hard to say that high-definition numbers and data were difficult to understand. In terms of quality alone, high-definition surveillance devices were hundreds of times more powerful than traditional surveillance devices, from shooting to video playback. So what should we know about HD surveillance? In fact, from the perspective of security monitoring to understand the operation of high-definition is also very simple.

A set of high-definition surveillance equipment is generally composed of the following devices: high-definition cameras, high-definition transmission lines, large-capacity storage and high-definition display, only this combination can play a high-definition effect, in order to reflect the charm of high-definition video .

The core of high-definition technology If you want to understand the core technology of high-definition, as long as you understand the above mentioned high-definition camera, high-definition transmission lines, large-capacity storage and high-definition display side, the following steps to explain:

First, the HD camera: a very simple word. To put it plainly, when a camera is a high-definition camera, it depends on the frame rate of the camera, the aspect ratio of the video, interlacing, or line-by-line. Usually, the frame rate of a high-definition camera is 24 to 60 frames per second, the video aspect ratio is 16:9, and the scanning mode is progressive scanning.

Second, high-definition transmission lines: high front-end high-definition camera video capture, the traditional transmission line before the way can not complete the large-capacity multi-line transmission needs. Currently used in the enterprise's monitoring network circuit, generally using optical fiber and optical fiber unit synthesis, such transmission can meet the need for multi-channel high-definition video transmission without affecting the normal operation of other networks.

Third, large-capacity storage: It is clear that the previous single hard disk storage model simply can not meet the day-to-day increase in the company's monitoring of video data storage. To store more, more data, you need more cluster storage. The use of high-definition clustered storage systems mainly solves the problem of large-instantaneous data volume accesses at the same time in multi-cluster server mode, thereby solving the problem of large HD data volume and slow operation at the same time.

Fourth, high-definition monitoring display: light with the above three high-definition monitoring equipment, mutual adjustment is not enough, for video playback problems, only high-definition display devices can make the best use. In layman's terms, the screen on the monitor display device can be divided horizontally into many, many scan lines. The finer the points, the clearer these screens are, and the greater the number of horizontal line scan lines.

High-definition monitoring architecture After reading the above points, everyone should understand the meaning of high-definition. Let's take a look at how the high-definition monitoring and control equipment in road traffic works. Take a school junction as an example:

In this section of 200 meters, a high-definition dome camera and high-definition infrared camera were set up in the school's traffic lanes. The dome camera can take turns to take pictures of the surrounding security, while the HDTV camera outside the site shoots the traffic on the road.

Through the high-speed bandwidth operation, the captured data is stored in the cluster storage device, so as to ensure the security of the video data. If a department needs to extract the video data in a specified time period, it can use the search function of related software to extract the data. Then send it to the HD display device for viewing.

Edit Comment:

With the perfection of high-definition video equipment, security has completely escaped the previous blurry interface. From the prevention of ATMs to the monitoring of roads and factories, they have played a very powerful role in deterring criminals.

From the above we can see that letting us see more clearly is no longer a one-sided slogan but an actual combat project being implemented.
