What is Infrared Thermal imaging technology?

The infrared thermal imaging camera was first developed for military purposes and used to enhance the night combat capability of the troops. In recent years, the technology has rapidly expanded to the civilian industry. With the gradual maturity of technology and the decline of cost, especially the emergence of uncooled infrared detectors, infrared products continue to expand the civilian market.

Compared to other night vision devices, infrared thermal imaging cameras have unparalleled advantages:

1. Real-time display of temperature at each point in the detection range, tracking temperature anomalies and troubleshooting and automatic alarm

2. Unlike other night vision technologies, no need for any form of illumination, clear imaging in all black conditions

3. Free from visible light interference

4. It can penetrate smog and has high visibility

Infrared thermal Q&A:

1. Does the infrared thermal imaging camera emit infrared light? Is it harmful to the human body?

The infrared thermal imaging camera does not actively send any light source such as infrared light, which is two different concepts. The temperature distribution is primarily imaged by the non-contact absorption/induction of surface thermal radiation from the photosensitive element. If you don’t send it, there is no harmful one.

2. Can the infrared thermal imaging camera pass through the wall?

No, the infrared thermal imaging camera is an instrument that senses the surface temperature of an object and visualizes it, so naturally it does not have the function of penetrating the wall.

The infrared detector senses the temperature, and it will not be affected whether or not there is an active light source. However, it must be pointed out that the infrared image is a temperature distribution map, which is different from the ordinary visible light image.

4. Does the infrared thermal imaging camera need to touch objects when detecting? Does the distance have any effect?

No, the infrared detector is non-contact, so you don’t need to touch the surface of the object to measure the temperature. The detection distance is similar to that of a normal camera, depending on the lens, but only within the range of the lens detection distance.

5. Is the infrared thermal imaging camera accurate?

Because it is non-contact thermal induction temperature measurement, the error is inevitable. The temperature range of the conventional thermal imaging camera is -20~150°C, the error is ±2°C, the temperature range of the human body temperature measurement camera is 20~45°C, the error is ±0.5°C, and the error of the high temperature thermal imaging camera is controlled. ±2%.
