HOW DO BODY TEMPERATURE DETECTION CAMERAS WORK?

Any object with a temperature above absolute zero will emit a detectable amount of thermal radiation as infrared. A thermal camera converts infrared radiation into grayscale values and matches those grayscale values, through an algorithm, to temperature values. These readings are overlaid onto live video and displayed on a monitor. On the display, individuals’ faces are highlighted with a green or red rectangle and their actual body temperature. If the body temperature of any person is above the present level, an alert is sounded, enabling security intervention to separate and isolate the individual for further testing.

These systems are able to process this information in real-time for up to 30 people amongst a moving crowd, such as when volumes of people enter a building or walk through an airport.

During the period they were in lockdown, London City Airport installed body temperature detection cameras, which became fully operational when flights resumed on June 21st.

Once a passenger is identified as showing an elevated body temperature, they will be asked to allow staff to retake their temperature, using a handheld, non-contact device, and will be required to answer questions about their symptoms and general health.

HOW DOES OUR BODY TEMPERATURE DETECTION SYSTEM WORK?

Any object with a temperature above absolute zero will emit a detectable amount of thermal radiation. A thermal camera converts infra-red radiation into grayscale values and matches those grayscale values to temperature values through an algorithm model.

Thermal cameras with high-temperature accuracy can help detect elevated body temperatures which may indicate the presence of a fever or in this instance a symptom of Coronavirus.

Our temperature detection system is ideal in particular for situations where it can be beneficial to measure the body temperature of employees working in large organisations, visitors into offices, or places that experience a high level of footfall, such as train and bus stations, airports, shopping centres, supermarkets and construction sites. Effectively any area or building where a large number of individuals can be expected to visit or congregate.
