Shenzhen Sunell Technology Corporation was cited for marketing thermal imaging cameras (including models SN-T5P-F, SN-F22-B, SN-T5H-P-F, and SN-T5/F) as medical devices intended to mitigate, prevent, or diagnose COVID-19 without FDA clearance or approval, rendering them adulterated and misbranded under the Federal Food, Drug, and Cosmetic Act. The company's website contained claims positioning the temperature screening cameras as disease prevention tools in the fight against coronavirus, including statements that the devices "played an important role in the work of prevention and control of epidemic" and served as "guardians for thousands of prevention and control site and points worldwide." These marketing statements established the products' intended use as COVID-19 diagnostic or preventive devices, which required them to undergo FDA review and authorization before being distributed in the United States.
