Taking body temperature helps to find COVID-19 patients and effectively prevent the spread of infectious diseases as early as possible. In response to the pandemic, Quanhom is cooperating with global partners to help develop various infrared body surface temperature rapid screening cameras and imagers(mainly providing LWIR athermalized and manual lenses), for example, thermal imagers used in entry-exit health quarantine at customs, airports, stations, terminals, schools, hospitals and office buildings for instant, secure and efficient identification of individuals with abnormal temperature.
