In some people's eyes, online games are more than just games. They will find something that cannot be discovered. For example, a security practitioner has discovered the use of security technology. Let's follow him to understand what the game involves. Security expertise:
First, low light technology In some games, players must wear a night vision device to see the target. After wearing the night vision device, it is a yellow-green world in front of the night, which is the effect of low-light night vision imaging.
The low-light night vision device, as the name implies, is a technique that uses the visible light (external light, moonlight, etc.) of the external environment for imaging. It is also used in some high-end video surveillance devices. Inside the instrument there is a light amplification device that amplifies the faint light of the natural world to achieve an observable effect by the human eye.

Second, passive infrared technology here is mainly about thermal imaging technology, in some sniper games, sniper gun high-power standard mirror open, you can see a red world in smoke, easy to lock the target.
Thermal imaging technology is a passive infrared technology, and is currently the main force of passive infrared technology. It mainly performs imaging by collecting infrared light emitted by human body heat. At the back of the lens, we can completely see the human condition, but we can't see the human face. This is why thermal imaging technology has been difficult to enter the field of video surveillance.
Why is thermal imaging red and obscure when observing? The reason is that thermal imaging technology is relative to active infrared technology (common surveillance cameras use this technology). It does not emit infrared light sources itself, but collects the infrared light sources released by the objects themselves (we know that general objects have infrared light). That is, the instrument is exposed to strong infrared light, and the resulting image is naturally red.
Thermal imaging technology has a strong adaptability to the environment and can be observed under severe weather conditions such as strong light, sandstorm, and heavy fog. It is not a complete night-time observation technique. There are also many examples of harsh environment observations applied during the day. However, one problem in video surveillance is that it cannot see people's faces. This poses some difficulties for the investigation and evidence collection. If thermal imaging is used in one place, it must be equipped with a strong emergency response department. When the invasion was observed, security personnel were immediately dispatched to take security measures. At present, foreign manufacturers such as Axis have begun to apply thermal imaging technology to video surveillance.
Third, active infrared technology active infrared technology is also suitable for night-time target locking, but it presents a black and white investigation effect map. Dynamic infrared technology is a technology for nighttime imaging by actively emitting infrared light. It has been widely used in video surveillance and is the most widely used technology in the field of video surveillance. In terms of imaging, its images are black and white, the imaging effect is good, and the imaging is stable. At present, surveillance cameras in supermarkets all have infrared lights, and all use active infrared technology.
So why is it black and white? Mainly because at night, the black-and-white screen after infrared night vision is the best for clearest night vision. The colored image will deviate from the original effect of the object due to light and other reasons, while the black and white images will have less color loss.
Active infrared technology is currently the most widely used night vision technology, but due to its large power consumption, it is not easy to observe hidden objects and other reasons. In today's energy saving and environmental protection, it has gradually been replaced by other technologies.
IV. Heartbeat detection technology The heartbeat detection technology is also a life detector. It is mainly used in games to determine whether there are any enemies nearby. The position of a person is determined mainly by detecting the person's heartbeat. The principle of wave phase superposition is used to determine the approximate azimuth and the number of wave sources. As the military can detect the target heartbeat behind the wall and in the bunker, but cannot identify the type and attribute of the target, and it needs to be judged by combining other information.
It can detect the target location beyond the line of sight, so that you can know where the other is without visual inspection. This is the simplest single soldier detection system. In the field of security, life detection systems have been widely used in the field of security and rescue. In the rescue operations such as landslides and coal mine explosions that cannot enter the accident, equipment based on this technology can be seen.
In fact, not only in the game, but also in many places in our schedule life, we have used security technology, but it is only ignored by us that we can see how important security is in our lives.
