An obvious physical change feature of COVID-19 is the rise of body temperature, so many places need to measure body temperature, but now whether hospitals, schools, airports, railway stations, shopping malls, companies and other crowded places, most of them use forehead temperature guns, which is relatively inefficient. Even some staff members believe that the epidemic has had little impact and helping people enter the venue to measure their temperature is very casual. Recently, the epidemic has shown a rebound trend. With the arrival of spring, the risk of infection has increased, and the situation of epidemic prevention and control remains severe, especially as the Spring Festival holiday approaches and there is a large flow of people from all over the country.
Summary of the advantages of thermal imaging temperature measurement gate guard machine
Firstly, the distance that can be "seen" is very far, and the imaging of thermal imaging cameras is not limited by ambient light. Long focal length thermal imaging cameras can observe people over 3 kilometers and vehicles over 6 kilometers.
Secondly, thermal imaging has strong concealment, as it passively receives signals without actively emitting detection signals, making it difficult for anti reconnaissance methods to detect. At the same time, thermal imaging has a very strong ability to identify concealed targets.
Thirdly, it is not affected by environmental factors such as rain, snow, fog, and haze, and has strong penetration ability. The imaging effect is almost unaffected under adverse weather conditions. Why almost? The rain has intensified and weakened.
Fourth, work 24/7 without interference from strong or low light. It will not be affected by strong visible light interference like other night vision devices. Low light cameras cannot capture images in the absence of ambient light.
Fifth, the "eyes" of firefighting. Early detection of fire hazards. Generally, fires are caused by inconspicuous hidden flames, and thermal imaging cameras can promptly detect abnormal high temperature points such as electrical appliances, coal seams, and grain warehouses, and sound the alarm in a timely manner. For example, in the treatment of straw burning, thermal imaging has repeatedly made achievements.
Sixth, the thermal imager can "see through". Thermal imaging has a certain degree of penetrability, which can penetrate clothing (thinner clothes), plastic bags, smoke, haze, etc.
Obviously, in public places, especially in crowded areas such as stations, factories, schools, etc., measuring body temperature through thermometers is slow, inefficient, labor-intensive, and the detection data cannot be fed back in real time, making it difficult to take timely measures. With factories starting production and schools reopening after the Spring Festival, there is an urgent need for rapid temperature screening of personnel as the country is about to experience large-scale personnel movements.
