　　What are the differences between night vision devices and infrared life detectors?

　　There are two common types of night vision devices: active ones use infrared spotlights to illuminate the target and receive the reflected infrared light to form an image; passive thermal imaging forms an image by identifying the infrared radiation of the target object. Infrared life detectors sense the temperature difference of objects to determine whether they are living beings. The former is mainly used for seeing and searching things at night, while the latter is used for searching survivors in disasters.

　　Do you know how infrared life detectors are actually used?

　　Miniature seismic detectors are unfamiliar to many people, but everyone knows life detectors. After an earthquake or fire, life detectors may be used to detect whether there are survivors in the rubble. There are many types of life detectors, including radar life detectors, infrared life detectors, and thermal response life detection equipment. Miniature seismic detectors are also a type of life detector, but their detection methods and usage scenarios are slightly different.

　　Detection principle of infrared life detector

　　An infrared life detector is a rather special type of life detector. Humans have heartbeats, but their heart rate and pulse are within a certain range. When there is someone in a vehicle, micro-seismic waves can capture and detect the person's heart rate, but it judges the existence of life through the frequency of vibration. Therefore, micro-seismic life detectors have environmental requirements; they cannot be placed in overly noisy places, nor can they be exposed to rain.

　　Constituent elements of infrared life detector

　　A micro-seismic life detector mainly consists of a machine tool, a display system, and sensors. Machine tools, industrial computers, and industrial computers are widely used in industrial products due to their higher stability than consumer computers. For example, the LCD displays we see at train stations and the large wall-mounted TVs in shopping malls are all controlled by machine tools. The system and display of micro-seismic waves are displayed in waveform on the screen during micro-seismic operation, allowing personnel to easily determine whether there are people in the vehicle. The sensors mainly consist of a geomagnetic sensor and a vehicle geomagnetic sensor. The role of the geomagnetic sensor is to eliminate the influence of ground vibrations, while the vehicle sensor is used to connect to the vehicle body. Micro-seismic waves can use the vehicle sensor to investigate whether there is life inside the vehicle; there is nowhere to hide in any part of the vehicle.

　　Application scope of infrared life detector

　　Currently, infrared life detectors are mainly used in prisons, customs, and border control. The main function of micro-seismic waves is also to prevent prison escapes and illegal immigration, thereby maintaining social order, and they can also be used for disaster relief!

　　Okay, that's all for today's explanation. I hope this article has been helpful. Have a nice day!
