As an important front-end for video surveillance, the impact of the “High-Definition†trend is naturally the most intense, and as a result, most video camera manufacturers gradually increase R&D investment in high-definition video cameras. As the saying goes, "If a worker wants to do something good, he must first sharpen his tools." Without a matching high-definition lens, the front-end high-definition camera can not play its due effect. Of course, the high-definition monitoring needs of security are not only on the camera, but also on the professional lens has also put forward a demand for high-definition. As a professional CCTV lens manufacturer in China, the AVENIRETOKU Seiko lens operated by Shenzhen Supersonics has strong technical strength in the research and development of the high-definition field. Here, Shenzhen Supersonic explores the concept and requirements of a million HD surveillance camera.
The biggest advantage of millions of HD is the high pixel and high definition. What kind of conditions must be achieved for surveillance cameras to be truly "high-definition lenses"? Shenzhen Supersonic Electronics Co., Ltd. technical experts believe that: "Compared to ordinary surveillance cameras, high-definition lens can achieve true high-definition, not only white, even at night and evening sunset, it can provide all-weather unbiased focus clear We usually take 70 percent of the field of view of the lens as the standard for the lens pixel, and then we can call it "HDTV lens" by distinguishing the lens edge and the pixel can reach more than 1000TVL. Currently, AVENIRETOKU Seiko HD series lens are Achieve this standard."
In order to demonstrate the effect of the HD lens more intuitively, we can take a close-up view of the AVENIRETOKU Seiko SV1040GNBIRMP lens shot map. The following test chart shows the overall picture actually taken by the SV1040GNBIRMP lens, as well as the center and square-shaped effects of the overall picture.

From the above test chart, we can do a brief analysis. In the overall picture taken by the AVENIRETOKU Seiko lens (SV1040GNBIRMP) (Fig. 1), we can see that the figure, figure and approximate lines in the picture can be seen very clearly, with high resolution and fine picture quality, and the picture color is sharp and sharp. . Figure 2 shows the effect of the center image after zooming in the overall image. After the center image is enlarged by 4 times, the image is still very clear. Therefore, the image pixels are high. Fig. 3 is a four-cornered image after the overall image is enlarged. After one of the corners of the test chart is enlarged by 6 times, the graphic lines are still sharply contoured, with sharp edges, rich layers, strong texture, and bright tone. Take this effect diagram as an example, when the contrast and resolution reach a certain height, it is the real ideal million HD lens.
At present, the SSV0550GNBIRMP of the 720P camera dedicated to the AVENIRETOKU Seiko lens is more representative. SSV0550GNBIRMP is a 1/3" target surface, aperture F1.5, CS interface, 2 megapixel HD lens, multi-layer coating technology used in this lens, can promote light penetration, enhance the overall lens through The amount of light makes the imaging brighter. Its infrared technology can significantly improve the imaging effect at night.
