The Technology

The EpidHunter heat-detection system enables non-invasive, autonomous monitoring of people in crowded areas such as airports, office buildings, shopping centers, and stadiums. In a matter of milliseconds, the simple, yet sophisticated, system identifies anyone with a temperature higher than 37.5 ºC /99.5 ºF.

Using a combination of sensors that collect diverse information from the area and the crowd as it moves, the system efficiently and discreetly identifies virus carriers, without the need to stop passenger flow or shut down other activities.

Based on groundbreaking patent-pending technology, the EpidHunter remotely measures temperatures with an extremely high degree of accuracy, ±0.1˚C, similar to clinical oral thermometers. Unlike other systems, EpidHunter continuously calibrates without the need for an external calibration source (blackbody) for maximum accuracy and a reduced number of false alarms.

The self-contained system comprises a device and a screen (tablet or computer) for simple, fast deployment. It does not require fixed infrastructure and offers end-to-end wireless encrypted connectivity.

The technology was validated after a long, multi-participant study conducted in collaboration with a health care facility that demonstrated the correlation between actual body heat and the heat measurement on the face.


People move through existing checkpoints or building entrances.
During the passenger flow, multiple sensors remotely monitor the individuals' radiated heat energy and the surrounding environmental parameters.
Using state-of-the-art algorithms, the system immediately identifies potential fever carriers.
Operators receive real-time alerts (visual, audible, silent) through a dedicated PC/mobile device user interface in order to take immediate action (per local guidelines).
MULTILAYERED detection in milliseconds minimizes the risk of spreading.
