Thermal cameras utilize infrared radiation in order to produce an image based on temperature. The image produced looks similar to a traditional camera but records the infrared wavelengths of light (hence the name) not visible by humans and displays a gradient of light or color intensity to distinguish high and low heat areas in the recording.
When thinking of thermal cameras, the first images in your head may be of high-stake secret missions carried out by special operations soldiers or fighter pilots. While this is certainly a use-case for this technology, thermal cameras have a range of practical day-to-day uses as well. For the average consumer, thermal cameras can be a great tool to track the heat output of your electronics, find cold or hot spots in your house in order to tackle a high electricity bill, pinpoint the source of water leaks, and even take your pet's or someone's temperature. This functionality in particular leads us to the reason for the huge growth in demand for thermal cameras in recent months.
With a growing awareness of illnesses and the desire to find ways to curb their spread in high-traffic areas, thermal cameras are used to identify fevers in people entering various kinds of public and private spaces. This is already being implemented in hospitals and businesses around the world in order to screen their employees and other visitors as they walk through the doors, which allows for a streamlined process to check each person without the need for additional staff or physical contact. Proponents of this usage of thermal cameras insist that it will slow down the spread of illness, and help keep the population healthy via the automated testing.
The price range for this technology is vast, with large corporations spending hundreds of thousands of dollars or more to set up complex, automated screening systems. However, there are a number of consumer-grade options that make it inexpensive and entirely possible to set up for the average consumer starting at just a few hundred dollars. There are even android and iOS thermal camera attachments that will provide this functionality right on your smartphone. Of course, if you are planning to use FLIR or thermal cameras in order to enhance the cleanliness of your workspace or home, it's important to also abide by basic hygiene rules in order to prevent the spread of illness. This includes washing your hands frequently, covering your mouth if you cough or sneeze, and making sure to stay home if you are sick.
