1. Working Principle of Thermal Imaging Devices

    Thermal imaging technology detects infrared radiation from objects, converting it into visible images through various processes. As warm-blooded animals, humans have body temperatures that create strong color contrasts in infrared lenses, producing clear silhouettes that help identify rescue targets.

2. Application in Emergency Rescue

    The golden window for rescuing missing persons is 72 hours. Traditional search methods are often inefficient and can miss this critical period. Modern thermal imaging devices have become essential in rescue operations. For instance, rescuers used thermal imaging to locate a 70-year-old Alzheimer's patient lost in a mountainous, densely vegetated area, ultimately finding him despite the harsh conditions.

3. Application in Outdoor Exploration

    Outdoor adventures often involve complex environments and adverse weather, making it easy for companions to get lost. Thermal imaging relies on the infrared radiation emitted by objects and their surroundings, unaffected by visible light or severe weather. This temperature difference creates a strong contrast on thermal screens, aiding in the quick location of lost companions and monitoring for potential dangers like wild animals.

4. Application in Law Enforcement

    Thermal imaging is invaluable in capturing fugitives, especially in dark, foggy, or rainy conditions. It easily identifies and locates suspects based on temperature differences, allowing for covert monitoring and assisting law enforcement in search and capture operations.

5. Application in Border and Coastal Defense

    Border defense is crucial for national security. Traditional methods like patrolling and ambushes are insufficient. Thermal imaging, which relies on energy and temperature differences rather than light, excels in dark, snowy, or rainy conditions. It enables continuous monitoring of borders, guard posts, unmanned stations, and entry/exit points, providing real-time, comprehensive, and visualized information for border management.
