Analysis of the application of night vision devices in the industry
1. Display of building contours
Nowadays, anti drug operations are becoming increasingly complex, and many places have shifted their cultivation from outdoor to indoor, which adds great trouble to law enforcement officers in investigating and collecting evidence. The application of night vision technology has solved this problem, as indoor planting requires the use of a 1 kW high halogen lamp to provide the necessary light and heat for growth. These lights heat up the interior of the building while also radiating heat towards the exterior surface of the building. Through thermal imaging, this heat can be seen evaporating, providing assistance for police anti drug operations.
2. Complete rescue missions and search for fugitives
It is possible to search for missing persons or fugitives overnight using low light mirrors and thermal imagers. People are strong radiators of heat, and their positions can be easily determined through thermal imaging. The use of a thermal imager can also detect people hiding inside hidden objects. For example, when the Georgetown Police Department was escorting two criminals, due to negligence, the criminals escaped, so the police immediately began the 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 it with a flashlight. Finally, using the handheld thermal imager produced by Leision Company, the criminal was caught in just 25 seconds.
4. Vehicle tracking
Vehicles emit a large amount of heat both 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 without turning on the lights. Patrol vehicles equipped with onboard thermal imagers can also track suspected vehicles entering or moving away from the parking lot by detecting the heat dissipation of vehicles that have just turned off.
5. Surrounding monitoring
When searching for suspects or dealing with emergency situations, the police take an action to block the accident site and dispatch surveillance in the surrounding area to prevent suspects from escaping or anyone entering the surveillance area to interfere with the case. The use of handheld or vehicle mounted thermal cameras can make surrounding control 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. Thermal imagers can also help police check the safety of commercial areas. Because thermal imagers 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, indicating that the house has been or is currently being robbed. Using this method is both effective and time-saving.
