The makers of specialized cameras to quickly scan for fevers as people enter crowded workplaces are grappling with soaring demand while confronting supply disruptions, forcing some to prioritize customers such as hospitals, executives told Reuters.
Many businesses around the globe have halted or reduced operations to help combat the spread of the novel coronavirus which causes the sometimes fatal COVID-19 respiratory illness.
Major employers such as Tyson Foods Inc and Intel Corp are experimenting with thermal cameras to ensure workers do not enter factories with potential illness, a critical part of maintaining production during the pandemic that could become more widespread as economies reopen.
Thermal camera companies such as U.S.-based FLIR Systems Inc, UK-based Thermoteknix Systems Ltd and Israel’s Opgal Optronic Industries Ltd say the surge in interest has caused a sales spike – with some tripling quarterly revenue or selling as many units in a few weeks as they had in more than five years.
The most common method for checking employee temperatures, used by Amazon.com Inc, Walmart and others, uses a handheld thermometer. But that limits how fast workers can enter a building and requires operators to stand inside the 6-foot (1.8 m) boundary recommended for social distancing.
Thermal cameras, which measure the amount of energy an object emits relative to its surroundings, represent a potentially safer non-contact alternative. The cameras scan people as they enter through doorways or hallways and send alerts to pull aside an employee for a check with a thermometer.
Intel Corp told Reuters it is evaluating thermal camera systems from several makers for use at a computer chip plant in Israel, where it is already checking employee temperatures. In the United States, meat supplier Tyson Foods said on Thursday it has purchased more than 150 infrared scanners and has installed them in four facilities that include pork plants in Iowa and Indiana and poultry plants in Arkansas and Georgia. On Monday, Tyson shut a hog slaughterhouse in Columbus Junction, Iowa, for the week after more than 24 cases of COVID-19 emerged involving employees at the facility.
“We expect that eventually every one of our food production facilities will have at least one in place,” said Tyson spokeswoman Hli Yang in a statement.
