What is the basic principle of Thermal Camera?

The principle of thermal imaging cameras is based on the physical phenomenon that any object with a temperature higher than absolute zero (-273.15 °C) in nature emits electromagnetic radiation. There is a clear correlation between the surface of an object and the intensity and spectral composition of its emitted radiation.

Infrared Thermal Imaging Camera consists of 5 parts:
1. Infrared lens: Receive and converge the infrared radiation emitted by the measured object;
2. Infrared detector component: Turn the thermal radiation model into an electrical signal;
3. Electronic components: processing electrical signals;
4. Display components: convert electrical signals into visible light images;
5. Software: Process the collected temperature data and convert it into temperature readings and images.

Advantage:
1. Full consciousness;
2. It can be used normally during the day and night.
3. It can be used in extreme weather;
4. Obstacles such as fog, rain and smoke can be seen through;
5. All heat-generating objects have nowhere to hide;
6. Monitoring of targets at night and under severe weather conditions at night;
7. Detect the temperature of people in the monitoring range.

Use range:
Transportation fortresses such as schools, office buildings, supermarkets, banks, hospitals, airports, railway stations, high-speed toll stations, and subways.

Sanan 2021 Thermal Camera with Black Body,It is also a dual-spectrum thermal imaging camera,designed for daily use, with simple and generous appearance design, rich interfaces, real-time body temperature detection high-definition display recording (detecting the temperature of people within the monitoring range), data transmission, etc. , Support multi-person simultaneous 0.1s ultra-fast body temperature detection, really fast and accurate (accuracy ±0.3℃), very suitable for crowded areas, can save a lot of labor and machine costs, and improve work efficiency.
