TDU Thermal Detection Unit

The TDU (Thermal Detection Unit) is an upgrade sensing kit for COVID screening compliance that can be installed on all current CEIA Security Gates.

TDU Thermal Detection Unit - detail

No thermal alarm

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.

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 person measurement using an infrared camera with automatic determination of the highest temperature
  • Zone of measurement can be selected on either the full IR camera frame or the face area only (high selectivity mode)
  • Indication of the thermal alarm on the control unit display
  • Continuous calibration of the thermal measuring system using two temperature-stabilized Reference Bodies.
  • 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.


TDU - Advanced IR processing

TDU provides advanced automatic capabilities to ensure correct temperature measurements even in unfavorable installations and difficult environmental conditions.For this purpose, the temperature measurement is taken on the face of only the person walking through. This selective capability allows to prevent possible measurement errors due to the following scenarios:
  • Queue of people seen in the IR camera frame with different facial temperature
  • Fixed hot-spot in the IR frame (i.e. floor or structures exposed to sun light)
  • Moving hot objects or areas, crossing the IR frame
  • Hot clothing, accessories or hot drinks carried by the person walking through. All the above cases that could generate a false febrile alarm are automatically rejected as the measurement is restricted to the face area only.
