Explosion-proof video surveillance 720P application trend in the field of security
The high-definition era of explosion-proof cameras is proceeding in full swing. Whether it is a manufacturer or an engineer, the pursuit of high-definition surveillance is in the direction of high pixels. However, high-definition surveillance should not just blindly pursue high pixels, but should pay more attention to the practicality of products and technologies when pursuing high pixels. The rational choice is justified. Huang Gong, the chief technical engineer of Shenzhen Shiguo Technology, said that this reason is also in line with the advertising slogan: only choose the right, not expensive. In the HD selection of explosion-proof cameras, the HD we need is not the higher the pixels, the better, but the most suitable pixels should be used for the most suitable places. At present, the explosion-proof HD cameras on the market are more popular with two types of resolutions, 1080P and 720P. We can use these two HD examples to make a comparative analysis. Because in the explosion-proof camera industry and the entire security industry, everyone does not have a unified standard for the concept of high definition, so from the perspective of the radio and television field, 720P is a high-level high-definition digital TV format developed by the American Society of Motion Picture and Television Engineers (SMPTE) The standard is the D4 standard digital TV display mode, and the effective display format is 1280 & TImes; 720; and 1080P is the D5 standard digital TV display mode, generally 1920 & TImes; 1080. Technically, 1080P and 720P use progressive scanning, and the actual scanning lines of each frame of image are 1080 lines and 720 lines. The progressive scanning method can solve the flicker phenomenon brought in interlaced scanning, and it can provide a clearer and more stable image surface. The most suitable human eye vision standard for progressive scanning is 75 images per second, but in the video surveillance of explosion-proof cameras, 30 images per second can already meet the needs of users. From the perspective of market application, the market of 720P and 1080P is obviously not on the same plane. 1080P requires a 23, 24 inch or above LCD screen to be viewed point-to-point. The CPU frequency is probably above 3G, or there is a hardware decoding graphics card. This resolution is mainly aimed at high-end consumers and requires product excellence. Faced with ordinary consumers, the 720P market is in great demand. In addition to the difference in user positioning on the app, the two also differ greatly in price. The technical content required for 1080P resolution explosion-proof cameras is significantly higher than that of 720P, so there is a huge difference in price between the two. For the field of security monitoring of explosion-proof cameras, the ultimate goal of security monitoring is to be able to see clearly, and only the videos that can be seen clearly are valuable to us. However, people often pursue high-definition and forget the particularity of explosion-proof monitoring. This is mainly due to the high-definition storm of consumer electronics products that stimulates security monitoring to quickly enter the era of high-definition. At the same time, on the other hand, people are also Video is regarded as the target, thinking that any high-definition surveillance is the higher the pixel, the better. In the field of broadcasting and television, although 720P has begun to show a decline, in the field of security, according to Huang Gong of Shenzhen Shiguo Technology, especially in the field of explosion-proof camera monitoring, the prelude to the 720P era can be said to have just been unveiled, and With the increasing popularity of HD surveillance, 720P will become the mainstream representative in the future HD standard of the explosion-proof camera industry. It competes with 1080P, but it is more of a complementary relationship. The reason for this situation is mainly based on the cost of equipment And the pressure of transmission and storage. It is an indisputable fact that HD surveillance has become the chasing trend of the market, and it will inevitably still occupy an important part of the market in the next few years, but the cost of chasing HD will also increase, so manufacturers and engineering companies Reasonable production and reasonable choices should be made while fully grasping the actual situation. With the continuous improvement of technology, the number of pixels of an explosion-proof camera may be infinitely improved, but the range of sight that the surveillance video can reach the human eye is always limited, so the surveillance video information of the explosion-proof camera can make people on a limited screen Obtaining valid information is enough, or Huang Gong's sentence: the choice of HD for explosion-proof cameras, only choose the right one, not the highest one.
