Technology Thermal Video Surveillance & Screening March 31, 2026 Thermal temperature cameras can detect elevated body temperatures from a safe distance, triggering real-time alerts for facility managers. Learn how these cameras work and how businesses can benefit from implementing them. Manually administering temperature checks can be cumbersome, inefficient, and invasive, especially if you have a large number of employees. Luckily, with new, innovative technology, you don't have to handle all temperature checks manually. Thermal cameras detect elevated temperatures and send alerts to you and anyone else within the company in real time. Using state-of-the-art monitoring, these cameras can actively determine if temperatures are elevated from a safe distance. While not a medical device, thermal cameras are intended to detect elevated body temperature, trigger an alert, and then allow you to advise the employee to have their temperature checked using an FDA-approved medical device. What Are Thermal Temperature Cameras? Thermal temperature cameras work like other security cameras, but the camera shows a heat map of everything appearing in view, instead of producing a clear image. While you won't see facial features, you'll be able to identify hot and cold points on the recorded video while the camera registers people and records their individual temperatures. Real-life thermal imaging cameras have been used by the military for years. They are now playing a critical role in facility management and security. How a Thermal Temperature Camera Works Modern thermal temperature cameras are highly accurate. With the right conditions, cameras can consistently report elevated skin temperatures when compared to measurements taken with a traditional thermometer. Beyond Temperature: The Full Power of Thermal Cameras Thermal cameras are also highly effective for: - Perimeter security — Detecting human beings in outdoor areas at night or in adverse weather conditions - After-hours intrusion detection — Identifying unauthorized individuals on your property even in complete darkness - Catalytic converter theft prevention — Detecting people under vehicles in parking areas - Vehicle lot monitoring — Identifying heat signatures across large outdoor areas At Watchmen Security, we specialize in deploying thermal camera systems that provide proactive security monitoring.
