Analysis of the Night Vision Devices Market
1. The outline of the building shows that nowadays, drug control operations are becoming increasingly complex, and planting in many places has also shifted from outdoor to indoor, which adds great trouble to law enforcement officers' investigation and evidence collection. The application of night vision technology has solved this problem, as indoor planting requires the use of a 1 kilowatt high halogen lamp to provide the necessary light and heat for growth. These lights heat the interior of the building while radiating heat towards the exterior surface. This heat can be seen evaporating through a thermal imager, thus providing assistance for police anti drug operations.
2. Complete rescue missions and search for fugitives. Use low light mirrors and thermal cameras to search for missing persons or fugitives overnight. People are strong radiators of heat, and their positions can be easily determined using a thermal imager. The use of a thermal imager can also detect people hiding in hidden objects. For example, when the Georgetown police station was escorting two criminals, due to negligence, the criminals escaped, and the police immediately began their pursuit operation. One of them fled to a grassy area and hid. The police passed by the criminal's hiding place three times but couldn't find him with a flashlight* Later, using a handheld thermal imager produced by the Lexion company, the criminal was caught in just 25 seconds.
3. Ensure the safety of police officers using night vision technology. Police officers can detect suspects at night without being seen. There was a case in California where law enforcement officers from the Drug Control Agency used thermal cameras to monitor a gang of criminals suspected of secretly manufacturing drugs, who were rampant in their strongholds in the mountains. Every night, they came out to search for the police officers who were monitoring them in the forest. The police officers used thermal cameras in the forest to keep themselves undetected by the gang, ensuring their own safety.
4. Vehicle tracking vehicles emit a large amount of heat during and after use. Thermal radiation not only comes from the engine, but also from the tires, brakes, and exhaust pipes. A police helicopter equipped with a thermal imager can track a suspect's vehicle from the air, even when its headlights are not on. Patrol vehicles equipped with on-board thermal imagers can also track suspect vehicles entering or leaving the parking lot by detecting the heat dissipation of vehicles that have just turned off.
5. It may not be possible to see the restored soil surface with the naked eye, but it can be seen with a thermal imager because when a surface is disturbed, the thermal profile of the surface is also disrupted, and the thermal radiation of the flipped soil is different from that of the compacted soil. By using this function of a thermal imager, buried objects can be found. The police once handled a case where a man, in a fit of anger, killed his wife. To cover up the evidence, the man buried the body in the backyard and covered the burial site with grass. The man thought he was doing it perfectly, but the police quickly found the body using a thermal camera. Nowadays, law enforcement agencies have begun to use thermal cameras to locate the victims' burial sites. It is generally believed that new graves can be found within 90 days with a thermal imager, but recently the Geography of the United States Society discovered an ancient Egyptian base 2000 years ago with a thermal imager.
6. Discovering hidden compartments, car factories often use thermal cameras to check for any malfunctions in their cars. The police use the use of thermal imagers to check if vehicles have partitions. Drug dealers often place drugs in tires, fake gas cylinders, and return pipes or other compartments of vehicles, and it is difficult to detect these flaws solely through visual inspection. By using a thermal imager, it is much simpler. For example, if the vehicle has two return pipes and one is fake, it can be observed through the thermal imager that the return pipe in use appears white and hot, while the other does not. It is reported that the joint federal inspection team on the border between the United States and Mexico has used this method to discover thousands of drugs and smuggled items of illegal immigrants attempting to cross the border.
7. When searching for suspects or dealing with emergency situations, the action taken by the police is to block the accident site and send a warning in the surrounding area to prevent suspects from escaping or someone entering the warning area from interfering with the case. By using handheld or car mounted thermal cameras, the surrounding control can be more effective. Nowadays, many countries have begun to use night vision technology to monitor the surrounding areas of criminal correctional institutions, factories, and airports day and night to prevent accidents. Thermographs can also help police check the safety of commercial areas. Because a thermal imager cannot penetrate glass, windows usually appear to be integrated with the wall. If a thermal imager sees something inside the house, it indicates that the window is open or broken, and therefore the house has been or is being stolen. Utilizing this method is both effective and time saving.
8. Environmental protection: The thermal radiation emitted by pollutants such as oil and chemicals is different from the radiation emitted by the surrounding soil or water. By using a thermal imager, these pollutants can be tracked and traced to their source. This use was discovered when the US Drug Control Agency was tracking a ship from South America. When the ship sailed into New York Harbor, the process of opening the sewage system and pouring sewage into the harbor was observed through the thermal imager. After this incident, agencies such as the US Drug Control Agency and the Federal Bureau of Investigation began to use their own advantages to consciously participate in environmental protection. Nowadays, thermal imagers have been extensively used by environmental organizations to search for factories that cause pollution, as well as in operations such as oil slicks on water.
