5 Reasons to Use Infrared Cameras to Detect Elevated Body Temperature
Can a Thermal Camera Detect Illness or Coronavirus?While these instruments offer significant benefits in public temperature screenings, thermal cameras are not diagnostic tools. They cannot confirm internal temperature — they measure surface temperature. They can, however, serve as a first line of defense. In conjunction with diagnostic measures, they can quickly identify individuals with elevated skin temperatures that might be the result of an illness. Thermal cameras measure invisible heat radiating from the surface of an object. The information from each pixel of the lens is then processed to express its corresponding temperature and assigned color. The image produced makes it possible to see a detailed and accurate visual depiction of the surface temperature of the object. It is important to note that not all thermal cameras are appropriate for medical settings — some are best suited for industrial, agricultural, or electrical uses.
Top 5 Benefits of Infrared Temperature ScreeningWhen used appropriately, there are numerous benefits for infrared technology to detect elevated body temperature. Understanding the technology and environmental conditions that affect reading is critical. With proper training, users can conduct safe, fast, and accurate temperature screenings.
1. Check Temperature from a Safe Social DistanceOne timely advantage of infrared temperature checkers is that they can accommodate social distancing requirements. While medical thermometers require close proximity, infrared temperature screening requires no person-to-person contact. Cameras mounted on metal detectors or handheld devices can be held at a safe distance and sound an alarm when it detects an elevated temperature. As everyone heads back to work and public life, infrared technology can make that transition safe and secure.
2. Keep the Masses Moving
In the wake of COVID-19, travel bans left large crowds of people waiting in airports to complete health screenings. As lines grew longer and delays began, the risk of infection and cross-contamination grew. The U.S. does not currently utilize infrared technology for health and temperature screening measures in airports. However, the ability to detect elevated skin temperatures has proven to keep things moving for the cruise industry, airports, businesses, and schools around the globe. Readings are completed in a matter of seconds, quickly identifying those who might need further screening.
3. Get Accurate Results
When used properly, infrared cameras detect temperature with a high level of accuracy. This means factoring in the camera’s specifications for distance in measuring, inputting conditions into the camera itself, and considering the emissivity of the object. ICI has devices with .1 to .2 ℃ accuracy, as well as some fixed and handheld systems coming accurate to .3 ℃, .5 ℃ and .8 ℃ accuracy. Our Infrared Training Institute also makes training available, to help ensure that users understand these devices and learn how to use them properly.
