With the rapid development of society and economy, intelligent security technology has entered the new field of information technology in the 21st century under the constant updating and development of modern science and technology, and the boundary between it and the Internet is slowly being eliminated. Without intelligent security technology, our work and life are very likely to lose peace. The country’s beautiful desire to promote a harmonious society is also likely to fail, and the development and advancement of world science and technology will also be affected.
Intelligent security technology is the informatization of related content and services, image transmission, storage and processing, etc. A complete intelligent security system must include access control, alarm and monitoring. However, we all know that there are millions of high-definition monitoring and ordinary analog monitoring points for monitoring.
So, where exactly is the difference between millions of high-definition monitors and ordinary analog monitors?
According to Mr. Liu, an engineer from the company's weak power division, a simpler way to say: Million HD surveillance is often called network surveillance or digital surveillance, and its monitor heads range from 1 million pixels to 5 million pixels. For example: FS -HD-SDI1080P HD Series (2 million pixels)
The middle transmission line adopts the network cable. The storage host uses the dedicated NVR host. If there is an Internet connection, the external network can directly view the image or all the images of a monitoring point through the external network. The storage of the image has not passed. Compression so that the playback effect of the image is the same as when viewing in real-time recording. Ordinary analog monitoring is usually also called analog monitoring. It is the most widely used for civil use. Its monitoring head is divided by resolution, ranging from 420 lines to 700 lines, and from the pixel point of view, it is equivalent to 300,000. Around the pixel, the transmission line in the middle is basically a coaxial video line. The host used for the storage is a DVR dedicated host. In the case of interconnecting an external network, the image can be viewed directly through the external network. The storage of the image is compressed. Therefore, the playback effect of the image is worse than that of the real-time recording.
From a purely technical point of view, the sharpness of the image of the surveillance system depends mainly on the horizontal resolution of the camera and the resolution of the rear-end display device. A good transmission medium can reduce the signal failure of the image during transmission, and the performance of the sensor chip plays an important role in the clarity of the camera. The lens of a million HD surveillance camera lens is different from that of an ordinary analog surveillance camera in terms of sharpness. The resolution of the center of the imaging plane of the camera is the highest. Although the resolution of an ordinary analog camera can basically meet the user's requirements, the resolution of the edge of the screen can be relatively weaker, and the monitoring effect for the corner is accordingly reduced. However, the high-definition cameras are the best in both central and edge corners.
In addition, the key factors that determine the lens definition are the lens material and purity, the precision of the lens, and the coating accuracy of the lens. Different from ordinary analog monitoring, the lens of a million HD surveillance camera adopts aspherical lenses, which can relatively reduce aberrations. Its miniaturized design and special optical technology enable high resolution of image quality from the center of the image to the edge. High-contrast, about 2.5 times more resolution than conventional lenses, ensuring high image quality and high definition even when the image is cut or enlarged. In addition, the difference between millions of high-definition monitoring and ordinary analog monitoring is also reflected in different spectral transmission capabilities, as well as differences in spectral correction capabilities.
At the same time, in order to prove the difference between HD surveillance and ordinary analog surveillance, the security departments of several residential districts in Dongguan were interviewed, as well as the departments of the urban areas, all of which found that the district security installation with millions of HD surveillance systems was carried out. It is relatively smooth and the community is relatively peaceful. Even if there are occasional special circumstances, the security department can also identify clues from the high-definition monitoring system and quickly solve the problem to ensure the safety of residents in the community. However, the situation is not so optimistic about which areas are only installed with ordinary analog surveillance. In many cases, the quality of surveillance is not clear, which delays the security work. * The department also said that the poor quality of the monitoring records often made it difficult to conduct investigations on some cases, and sometimes even threatened the lives of the people.
Finally, the chief person in charge of Dongguan Tongtong Communication Technology Co., Ltd. of Dongcheng West Road visited the exhibition of related products. The reporter learned that Chuangtongbao Communication Technology is a comprehensive high-tech company specialized in high-definition digital surveillance, digital matrix, group telephone, network communication and network transformation projects. They have established a good reputation in many major areas such as major government agencies, safe campuses, factories, and major banks, and have won many praises in the industry. More importantly, Chuangtongbao Communication Technology Co., Ltd. has invested a lot of manpower, material resources, and financial resources in the development of the monitoring system in Dongguan and the monitoring and installation techniques in Dongguan. The achievements are quite remarkable. For many years, it has been contributing a small amount of effort to Dongguan security technology and Dongguan monitoring engineering.
