What is infrared video
Infrared video is a technical means of capturing and recording images using infrared technology. Unlike ordinary visible light video, infrared video can capture infrared radiation that cannot be directly observed by the human eye and is widely used in military, security, medicine, industrial detection and other fields. This article will introduce in detail the principles, application scenarios and recent hot topics of infrared video.
1. Principle of infrared video

The core principle of infrared video is to use the infrared radiation (thermal radiation) emitted by objects to generate images. Infrared is the part of the electromagnetic spectrum with wavelengths between visible light and microwaves, usually divided into near-infrared, mid-infrared and far-infrared. Infrared cameras convert infrared radiation into electrical signals through special sensors (such as microbolometers), and then use image processing technology to generate visual thermal images.
| Infrared band | Wavelength range | Main applications |
|---|---|---|
| Near infrared (NIR) | 0.75-1.4 micron | Night vision, security monitoring |
| Mid-infrared (MIR) | 3-8 microns | Industrial detection, gas analysis |
| Far infrared (FIR) | 8-15 micron | Medical imaging, building heat loss detection |
2. Application scenarios of infrared video
Infrared video technology is widely used in many fields because of its unique advantages:
1. Security monitoring: Infrared cameras can capture clear images in complete darkness and are often used in night patrols, border surveillance and other scenarios.
2. Medical diagnosis: Infrared thermal imaging technology can be used to detect human body temperature distribution and assist in the diagnosis of inflammation, blood circulation abnormalities and other diseases.
3. Industrial testing: Through infrared video, problems such as equipment overheating and circuit faults can be quickly discovered to improve maintenance efficiency.
4. Military use: Infrared technology is widely used in military equipment such as night vision devices and missile guidance.
3. Recent hot topics and hot content
In the past 10 days, topics related to infrared video technology have mainly focused on the following directions:
| hot topics | Main content | heat index |
|---|---|---|

4. Future development trends
With the advancement of technology, the application scope of infrared video will be further expanded. The following trends may appear in the future:
1. Higher resolution: The pixel density of infrared sensors will continue to increase, making images clearer.
2. Integration of artificial intelligence: AI algorithm will be used to automatically analyze infrared video data to improve detection efficiency.
3. Consumer level popularization: Infrared cameras may gradually enter daily devices such as smartphones.
In short, infrared video technology is developing rapidly and its application prospects are very broad. Whether it is security, medical or industrial fields, infrared technology will play an increasingly important role.
