Application of infrared thermal imaging technology in the security field 1: Monitoring of targets at night and in harsh weather conditions

At night, due to well-known reasons, visible light equipment can no longer work normally. If artificial lighting is used, it is easy to expose the target. If low-light night vision equipment is used, it also works in the visible light band and still needs external light for illumination. The infrared thermal imaging camera passively accepts the infrared heat radiation of the target itself, and can work normally no matter day or night, and will not expose itself.

Also under harsh weather conditions such as rain and fog, due to the short wavelength of visible light, the ability to overcome obstacles is poor, so the observation effect is poor, but the wavelength of infrared light is longer, especially for infrared thermal imaging camera working at 8-14um. The ability of rain and fog is high, so the target can still be observed normally. Therefore, at night and in bad weather conditions, infrared thermal imaging monitoring equipment can be used to monitor various targets such as people and vehicles.

Application of infrared thermal imaging technology in the security field II: Fire Monitoring

Since the infrared thermal imaging camera is a device that reflects the surface temperature of an object, it can be used not only for on-site monitoring at night, but also as an effective fire alarm device. In large-scale forests, fires are often caused by unobvious hidden fires. of.

This is the source of destructive fires, and it is difficult to find the hidden signs of fires with existing common methods. The application of infrared thermal imaging camera can quickly and effectively find these hidden fires, and can accurately determine the location and scope of the fire, and find the ignition point through the smoke, so that it can be known, prevented and extinguished early.

Application of infrared thermal imaging technology in the security fieldIII: identification of camouflage and concealed targets

Ordinary camouflage is mainly to prevent visible light observation. Ordinary criminals usually hide in bushes and woods when committing crimes. Due to the harsh outdoor environment and people's visual illusions, it is easy to make wrong judgments.

Infrared thermal imaging devices passively accept the thermal radiation of the target itself. The temperature and infrared radiation of the human body and vehicles are generally much higher than the temperature and infrared radiation of vegetation, so it is not easy to camouflage and misjudgment.

With the development of photoelectric information, microelectronics, network communication, digital video, multimedia technology and sensing technology, security monitoring technology has moved from traditional analog to highly integrated digital, intelligent and networked.

With the increasing demand of the market, modern high-tech is almost applied or will be applied in the security monitoring system. The rapid development of infrared thermal imaging technology in modern sensing technology has also begun to be applied in security systems.
