​

• 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
