Man lives surrounded by various objects and living beings, each of which has advantages over others. That is why there is a clear division between predators and prey. They all, in turn, also have their strengths and weaknesses. Compared to more robust and faster animals, there are no such advantages. Therefore, from the tribal times, she sought to find in herself the best abilities that could not only protect her but also provide opportunities to defeat enemies or hunt; such an advantage could be given by the ability to see at night, which all mankind has longed for since ancient times. This became possible only a few dozen years ago, thanks to the invention of technology that can give such skills for a specific time. This is night vision technology. You could see her work in various military films because this is the first field where it was applied, or in action films where to track and defeat the enemy, the main character uses magic glasses that allow you to find the enemy in the dark and deliver a devastating blow, or in scenes with the pursuit of criminals in the middle of a large flow of cars at night, where the main character tries to save his beloved who has been kidnapped. The thief runs at breakneck speed with the lights off and breaks away from the chase, but it's not time to give up, and with the help of an additional function on the monitor in the car, we see the image of the desired car and follow it. So all these films show us the operation of night vision devices, which greatly simplify our lives. However, it is worth understanding what types of such devices there are, how they are arranged, what helps us see at night, and in which areas they can be used for the benefit of humanity. If you are sure that such devices are used only by the military, then you should ensure the opposite.

Brief info about thermal vision technology.
The need to invent a technology that would allow you to see at night arose long ago. However, insufficient awareness in this area and insufficient data for processing left attempts to invent such a tool fruitlessly. Until after the First World War, humanity did not feel a real threat of a new military conflict. Politicians of all countries were determined, but all scientists worked to invent new technologies that would give the military a significant advantage and bring them closer to victory. Night vision became such a device. Thanks to the work of infrared rays and sensors that capture information, it became possible to see in the dark. And although the first devices were quite heavy and oversized, during improvements and constant work on the convenience of their use, the world saw decent night vision devices that resemble modern ones. However, simply seeing in the dark was not enough. This technology worked with residual light and had certain conditions to use, so military engineering went further and modified the existing technology. This is how thermal imaging technology was born. Its peculiarity lies in that it does not work for light like its predecessor but with heat, which is emitted by every object, regardless of its living nature. The male's ability was a significant breakthrough because now, even a ray of light was not needed to see in the dark. Each body has its energy. Therefore, it emits a specific temperature; the thermal imager can read this heat and transform it into an image. However, different measurement scales were developed since each body has an additional heat output. For example, for observing living objects, a scale that depicts high temperatures is sufficient so that the image will be in the range of yellow to red; as for inanimate objects, their temperature is lower, so they have their measurement scale from blue to violet. These two varieties have been used for a very long time. Recently, another scale has emerged, black and white, where weak areas are high temperatures, and darker areas are colder. Different ones may be suitable for each case, so when buying, we advise you to pay attention to this and choose the ones that will be comfortable and understandable for you.
This technology is widely used in military control and domination over the enemy, but this is not its only purpose. This technology is also ubiquitous among rescue workers. Because to save the victims, it is necessary to carry out rescue operations without a break to pull everyone out of the wreckage as quickly as possible. Therefore, a thermal imager will come to the rescue here, ensuring timely response and detecting people's heat. In general, thermal imaging technology is used in medicine, the military, security service workers, hunters, animal protectors, photographers, and various special services.

Thermal Imaging Systems in airports.
Traveling is becoming an increasingly popular pastime among people from all over the world, and it's no wonder because traveling allows you to learn about a new culture, meet interesting people, and develop your perspective. It is exciting to fly to another part of the world and try to change your life according to their traditions, customs, and pace of life. Therefore, the need for high-quality air transportation is growing. An important factor is also the improvement of airplanes, which makes it possible to fly to another corner of the world without refueling; this opens up new and new opportunities among travelers. That is why the number of passengers in airports worldwide is proliferating, regardless of their size and how many flights take off from the runways daily. For the country to receive more visitors, the state is developing new, more modern, and larger airports and airplanes; of course, the safety of staying at new airports is a priority, and the security system is constantly developing. But despite all this, the level of terror and crime on regional and international flights remains appalling. What motivates the creation and introduce new systems of supervision and control? As a result of the unusual behavior in the airports and beyond, a 24-hour video surveillance system using night vision cameras was introduced. And since there is a 24-hour control under which airport security service employees train, the crime level should have decreased. But depending on the configuration, the presence of blind spots in the camera, and the possibility of error, so-called false alarms often occur. Due to insufficient visibility or image decoding errors, the security service directs the patrol to the wrong place, thereby undermining the trust of airport employees in other passengers. On the other hand, when a crime happens, and for some reason, it is not visible on the cameras. Another problem is that night vision cameras require partial light because they don't work in complete darkness, so their use is only sometimes possible. All this caused a particular conflict because there are 24-hour cameras for surveillance and control, but their effectiveness is much lower than planned. Thus, the problem of increased crime at airports still needs to be solved. To solve these significant problems, the idea of using another technology for night vision arose a technology that can work without light since the sensors work with the heat of objects. This is thermal imaging technology. Any heat emission from people, animals, equipment, or other devices has its specific temperature, making it possible to monitor any changes regardless of the time of day and the room's illumination level. And thanks to new improvements, thermal cameras provide a better image and can monitor movement to the smallest detail. At the same time, there is a specific difference between all objects, which significantly reduces the risk of false alarms. Nothing is generally impossible for a thermal vision camera at night; its operation does not depend on light or weather; it is simply an ideal device for round-the-clock surveillance and recording any crimes. And the method of their placement is devised in such a way that there are no blind zones at all; the height and distance between them are calculated so that the zones partially overlap, and there are no gaps in the image.

Medicine usage of Thermal Imaging Systems in airports.
Airports are considered one of the most visited spaces, on par with public transport or shops. Therefore, it is not at all surprising that after the beginning of the pandemic, there was an urgent need to increase the level of security at airports because a large number of people can carry the disease, and it will spread at a phenomenal speed, based on how many people visit one airport with many different international flights. Therefore, the issue of safety and detection of persons who can carry the virus has become a priority in recent years. While studying the disease, doctors discovered certain regularities in patients' temperature regimes and conducted several studies to confirm them. Not to mention that the airport space has been divided and distance markers have been recreated, but if you are in a hurry to catch a flight and there are many people around, only some people keep a safe distance. Therefore, as a matter of priority, all airports were equipped with checkpoints at the entrance and exit to check the temperature of all passengers, accompanying persons and airport staff. Of course, this greatly simplified the identification of the sick, but the queues at the checkpoint did not shorten since it takes time to measure the temperature of each passenger. The solution was found quickly. Since thermography has long been used in medicine to detect inflammatory processes and has shown promising results, it was decided to equip all airports with thermographic scanners. This device is similar to an arch, equipped with thermal cameras fixed on a person's head during the passage, thus showing his body temperature. The principle of operation is very similar to an ordinary thermal imager, just with certain modifications. Since you don't need to look for an enemy or assess the general situation here, the target here is the person's body temperature, which can range from yellow to red, depending on the heat the body emits. It became a simple salvation and a solution to two problems at once. First, now there was no long line at the entrance to the airport, and people did not gather, which slowed down the spread of the virus. Second, such scanners made it possible to measure temperature and track possible disease carriers, identify them and refer them for additional testing. Therefore, thermography was very useful for a safe stay and the airport area and helped prevent the virus's spread among airport visitors.

Thermal Imaging Systems are ubiquitous not only in the military field but with their help; improvements are made in our ordinary civilian life, as well as the progress of the security system and development in the medical field. It is tough to imagine even a day without using this technology because we constantly go to stores, have surveillance cameras at home, or travel. In any of these cases, you are tangential to thermal imaging technology. It is independent of your profession or standard of living. To be able to choose and use a thermal visa, you need to know several nuances. First, you need to determine precisely how and in what situations you want to use it; the configuration, image quality, and additional functions will depend on this. Suppose we are talking about thermal imaging cameras for your safety and the safety of your relatives. In that case, it is essential that cameras record the entire perimeter and that there are no blind spots. Image quality is also vital for timely response and the assignment of specific measures. To feel safe outside the home, every businessman or government is also concerned about improving the system and the quality of response. Thermal imagers are extremely important for all spheres of life, so you should consider their importance.
