To help stem the alarming spread of infections worldwide, LILIN introduced an innovative monitoring system capable of measuring the body temperature of individuals and detecting whether they’re wearing a protective mask. Based on LILIN’s revolutionary AIDA artificial intelligence, this “touch-free” system is a milestone in disease prevention and is suitable for medical institutions, large public gatherings, schools, retail outlets and businesses of all types.
In June at the Taiwan Global Anti-COVID-19 Pavilion, LILIN engineers demonstrated how the system supports high-precision facial temperature measurement within a distance of 30 inches from face to camera. The entire testing process requires less than 3 seconds per person.
While different diseases affect people in a variety of ways, the most common symptoms during this epidemic has been a fever and cough. While a cough can be heard, a fever is easier to ignore. This makes the monitoring and detection of persons running a fever critical to flattening the curve, and ensuring the successful reopening of businesses.
In developing the system, LILIN engineered the P3T6522E2-F dual-sensor IP camera, which can capture high-resolution color video through a 2-megapixel CMOS sensor and detect abnormal temperatures by using a built-in thermopile sensor that targets the facial area.
After it’s captured, temperature data and video are streamed in real time to the NVR51T4E 4-port Temperature Measurement network video recorder (NVR) for analysis. An alarm is activated when a temperature exceeds the defined temperature range, or the NVR can trigger digital output to, for example, an access control system. Digital video is stamped with an on-screen display of the temperature reading, so the infected person can be identified immediately, alerted and sent to a medical facility for testing before potentially infecting those around them.
To avoid false positives, the NVR51T4E can be adjusted to reflect the ambient temperature of the testing area. Up to three individuals can be measured simultaneously.
Along with the new cameras and NVR, LILIN is offering its NAV6001AI-M AIDA mask-detection server. When connected to a LILIN temperature-monitoring camera, it will identify in real time individuals not wearing a mask in public areas that require their use. In the event the NAV6001AI-M detects a person not wearing a mask, an audio or physical alarm is triggered to deny access to a facility.
The NAV6001AI-M AIDA mask-detection server easily integrates into the LILIN camera and NVR solution, although it doesn’t require the NVR and can be used as a stand-alone solution with a P3T6522E2-F camera.
