In order to comply with COVID containment measures, screening operations should also include the measurement of body surface temperature to intercept fever temperatures. This has to be done without adding any extra manual operations and avoiding any contact between screeners and the persons screened.
Description
Thermal alarm: the control unit shows the body surface temperature
The rapid spread of COVID-19 infections has required the introduction of containment measures at all levels. Measures include the use of face masks, social distancing and also the measurement of body temperature as an indicator of possible virus infections.
Security checkpoints at the entries to airports and other sensitive buildings should now be equipped with security systems compliant with the new measures. This means detecting target threats with the minimum rate of nuisance alarms in order to limit the number of secondary checks necessary, reduce contacts between checkpoint operators and persons in transit and reduce waiting times upstream from the system. All in all, this requires a metal detector with a very low nuisance alarm rate.
In order to comply with COVID containment measures, screening operations should also include the measurement of body surface temperature to intercept fever temperatures. This has to be done without adding any extra manual operations and avoiding any contact between screeners and the persons screened.
The TDU (Thermal Detection Unit) is an upgrade sensing kit for COVID screening compliance that can be installed on all current CEIA Security Gates, allowing the following functions:- Simultaneous threat and fever detection on all screened persons
- Accurate body surface measurement using an infrared camera with automatic determination of the highest body temperature
- Indication of the thermal alarm on the control unit display
- Continuous calibration of the thermal measuring system using two temperature stabilized Reference Bodies. Each reference is constantly controlled by a sensor device that is 100% tested on a production setup that is NIST traceable and verified with equipment that is calibrated to ISO/IEC 17025 accredited standards.
- Transit direction and count verification with synchronization of the temperature measurement of the inspected person inside the gate. This ensures maximum accuracy and unique signalling
