Automated temperature scanners equipped with OPX technology calculate body temperature rather than superficial skin temperature
While common handheld scanners capture the skin's surface temperature, FeverWarn calculates internal body temperature with MachineSense's OPX technology, which combines and processes data from a trio of sensors through an AI-based algorithm. This higher degree of accuracy helps vigilant workplaces and public spaces strengthen their defense against virus transmission to protect employees, visitors, students, customers, worshippers and patients.
Handheld temperature scanners are cheap, but unsafe. They require the operator to stand very close to a person before knowing whether or not they have a key indicator of illness. They are also dramatically impacted by high or low ambient temperatures which, at best, skew temperature readings and, at worst, make temperature unreadable when used outside of their suggested 70 to 94 degrees Fahrenheit ambient temperature range. With most of the country's climate below or above that range depending on the season, workplaces and public agencies that are serious about keeping fevers out while minimizing detection costs are turning to FeverWarn with OPX technology.
FeverWarn with OPX utilizes three sensors - an infrared sensor to scan skin temperature, an ambient sensor to capture the temperature of the ambient environment, and a proximity sensor to measure how far away the fist or wrist is when scanned. The sensor data is processed by the proprietary OPX algorithm to accurately calculate body temperature. FeverWarn signals an alert when it detects an elevated body temperature and, depending on the model, can disable a door badge to prevent entry, for instance. Because of its three sensors, FeverWarn with OPX scanners can operate in environments ranging from 40 to 105 degrees Fahrenheit.
