The 4K Camera is getting more and more popular recently so what is the 4K Camera?
The 4K Camera/ 4K Ultra HD Cameras/ 4K Waterproof Cameras/ 4K Night Owl Cameras/ 4K Camera Monitor/ 4K Camera Wifi/ 4K Camera CCTV , also called the 4K HD Network Camera or the 4K HD network camera(today we mainly introduce the 4K HD network camera), adopts the new hardware platform with higher performance and is equipped with the 12 million pixels ultra-high-definition image sensor, which has the characteristics of the accurate and natural color reproduction and the clean and delicate picture quality.
What about the technology advantages of the 4K Camera?
The most outstanding technology advantage of the 4K Camera is the 4K technology.
First of all, the most obvious feature of 4K technology is that its improved display resolution makes the picture more refined. There are two important key factors that affect the fineness of the picture, one is the pixels of the picture, and the other is the vertical resolution of the picture. The higher the pixels of the picture is, the finer the pixels on the picture of the same size will be, and the smaller the lattice will be. In fact, the human eye is very sensitive to the vertical resolution of the image, the higher the vertical resolution is, the more details and levels the human eye can recognize. What the 4K technology can achieve in the surveillance field is to enhance the vertical resolution of the picture while increasing the pixels, making the details and levels of the picture more accurate.
All in all, the 4K Camera has a great improvement in the image quality and it would be more widely used by more and more people.

4K means that the resolution is 3840*2160 and the aspect ratio is 16:9; under which standard, the CMOS progressive scan can reach 2160P. Compared with the 2 million pixels, the 4K high-definition network camera has higher vertical resolution, more accurate picture details, clearer display, cleaner and more delicate, and can make people feel immersive; which can effectively help to saitisfy the monitoring needs of the high-definition picture quality at the places with the complex lighting.
Secondly, the enhancement of the color levels and details makes the picture closer to real life. The transition from the standard-definition to the high-definition display system is actually mainly the upgrade in resolution, while there is no significant improvement in color. However, in the era of 4K Ultra HD, in addition to the leap in resolution, the changes in color are particularly noticeable; which is reflected in the latest BT.2020 ultra-high-definition broadcasting standard promulgated by the ITU-R.
Finally, the 4K video systems process the 10-bit or even 12-bit encoded video signals. At present, the HD or Full HD systems usually use the 8-bit video systems, while the 4K Ultra HD uses the 10-bit or even 12-bit video systems. Therefore, the 4K video system has a greater improvement than the HD system whether in the gray level transition or in the color depth level performance.
According to foreign media reports, in the late spring of 2010, the whole world is paying attention (often in real time) to a new environmental disaster: an oil rig running deep in the bottom of the Gulf of Mexico exploded, and the oil well below the platform will have a large amount of oil. Spewing into the sea above. The offshore oil rig belonging to British Petroleum Company (BP), called "Deepwater Horizon" (Deepwater Horizon). Previously, the platform completed the world's deepest drilling mission - nearly 1.6 kilometers deep with 11.3 kilometers of rock formations. After the explosion, the impressive depth of the Deepwater Horizon became its most serious flaw, as it turned out that the drilling could not be sealed on such a deep seabed. The Gulf of Mexico oil spill was the most serious marine oil spill in history.
While BP was repeatedly repairing through unsuccessful methods, some observers quietly discussed a very different and unconventional method: detonating a nuclear bomb underground and using molten gravel to seal the crack. "It is beginning to become nuclear submarine surprisingly feasible and reasonable ...... I never thought I would 'hear' own written so out loud," engineers at the University of Texas Steven Weber ( Steven Webber) wrote. However, the nuclear explosion seems to have never been a serious possible option. A nuclear explosion may destroy a well rather than seal it, making closed drilling impossible. A working group convened by US Secretary of Energy Zhu Xiwen ruled out the possibility of this method; a senior official said, "This is crazy."
This idea may not be as crazy as it seems, or it can be said that at least this madness is not without precedent. In the 1960s and 1970s, the Soviet Union successfully used underground nuclear explosions to extinguish out-of-control gas wells four times. This is only part of a large-scale plan for the Soviet Union to use nuclear explosions for a variety of peaceful purposes; the United States has similar but smaller plans. Much of the information about the attempts made during these Cold War eras was not known until after 1998, when Milo Nordyke, former head of Lawrence Livermore National Laboratory, published an authoritative report on the incident.
For most people, it seems difficult to accept nuclear bombs as a tool for engineers to transform the planet. We can recall the mentality of nuclear energy after World War II. People are eager for everything related to the nuclear. People think that their cities, cars and lives can quickly get energy from the splitting and combination of atoms. . The Soviet representative declared at the United Nations: "The Soviet Union did not use atomic energy to raise the inventory of atomic bombs, but to use the atomic energy for the purpose of developing its own economy: exploding mountains, changing river courses, irrigating deserts, and opening new roads in inaccessible areas." Also at the United Nations, President Eisenhower issued a similar statement in his Atoms for Peace speech: "It is not enough to take such weapons from the hands of their soldiers. It must be placed in those Know how to deprive them of their military shell and adapt them to the hands of the art of peace. "Of course, the United States and the Soviet Union were constantly expanding their nuclear arsenals, and the atomic bombs of the two countries could destroy humanity many times.
In 1957, mankind finally took a solid step in the peaceful use of nuclear explosion. The United States conducted the world's first underground nuclear explosion test at 270 meters below the surface of the Nevada desert. The test was fully in line with the planned plan and there was almost no damage or radiation on the ground. “There was a great increase in enthusiasm and confidence, making nuclear explosions for peaceful uses possible and safely implemented.†For the next 16 years The United States' Plowshare Program has conducted 12 additional nuclear explosions, mostly to test the effects of using nuclear weapons to extract natural gas or excavate the surface. A plan involves the use of a string of nuclear bombs to create a pathway that can replace the Panama Canal.
The Soviet Union later joined the competition and was more enthusiastic. In 1965, the Soviet Union carried out its first civilian nuclear explosion. The nuclear explosion is closer to the surface, with the aim of exploding a large pit near a river in Kazakhstan, which can be used as a reservoir to provide irrigation water during the dry season. The test was very successful. According to reports, Efrim Slavskiy, the head of the project, jumped into the newly built reservoir and proudly became the first person to swim inside.
A year later, Soviet engineers discovered another creative use of nuclear bombs. At that time, an uncontrolled gas well in Uzbekistan had been burned for nearly three years, and 12 million cubic meters of natural gas was sprayed every day, enough for all the families in St. Petersburg. To make matters worse, these natural gas contain high concentrations of toxic hydrogen sulfide, which is very dangerous for workers trying to close gas wells and surrounding residents. After all the conventional methods failed, the Soviets decided to use nuclear bombs, hoping to close the gas wells deep underground. They drilled a new hole near the well, placed a specially designed nuclear bomb, and filled the hole with concrete. The nuclear bomb exploded after 23 seconds, and the gas well that had burned for 33 months was finally extinguished.
These early successes initiated a positive program that included 122 nuclear explosions and continued until the end of 1988, when the Soviet Union began to collapse. Soviet engineers not only used nuclear bombs to close burning natural gas wells or excavate lakes, canals and dams, but also used to increase oil production, build underground cavities, find geological resources and create new elements. Perhaps the most amazing application is to build large underground spaces that handle toxic waste, separating it from the biosphere and water. In the post-Soviet era, Russian scientists proposed to put waste from nuclear power plants deep underground, where they detonated nuclear bombs, and the waste and rock were merged into stable plots, and their radioactivity could be gradually dissipated over a long period of time. Nuclear bombs may be the most effective means of removing nuclear waste. It is a bit ironic to think about it.
In the 1970s and 1980s, the image of nuclear power in the public's mind showed a major decline, from the future energy miracle to a terrible environmental disaster. The United States and the Soviet Union have ended their various nuclear explosion plans, and it seems that the political significance of these plans is far greater than the actual use. This may explain why the idea of ​​peaceful use of nuclear bombs will also cause people's inner resistance. The invention that once symbolized the world's first-class creativity has become an eternal footnote for human arrogance.
