Elevated Body Temperature Screening

Higia is SENSIA’s advanced solution for reliable Elevated Body Temperature screening based on thermal imaging.

This new Elevated Body Temperature detection solution for intelligent temperature measurement of people is based on SENSIA’s RedLook software.

This screening monitoring tool allows to automatically detect and alert the person who stands out from the rest by an abnormal body temperature.

High reliability thanks to real time closed loop calibration.

IEC 80601-2-59:2019

The HIGIA Elevated Body Temperature functionality of RedLook analyzes every subject’s temperature and compares it to the previously specified threshold. If the subject’s temperature is above the threshold an alarm is generated.

This operation mode has been developed to operate according to the IEC 80601-2-59:2019 standard for infrared thermographs.

One by one, each person shall stay in the specified position facing the thermal camera with the face completely uncovered. HIGIA will measure the temperature of the subject in the region medially adjacent to the inner canthus of each eye.


HIGIA automatically detects every person (green rectangle) who enters in the field of view of the thermal camera and measures the skin temperature in real time.

The ability of HIGIA to distinguish people from the rest of the elements in the screen allows to analyze only the temperature of each subject coming through avoiding false alarms due to other hot spots in the field of view such as heaters, lights, hot cups, etc.

HIGIA does not provide person identification, so the identity of the evaluated subjects remains anonymous at all effects. HIGIA just identifies people from the rest of the elements in the image prior to the temperature measurement.

Thermal camera versions

There are 4 HIGIA thermal camera main versions which can be delivered in three different aluminum housings.

  • Multiple resolutions: High Sensitivity with 384 x 288 pixels detector and eXtra Sensitivity with 640 x 480 pixels detector
  • Multiple connectivity options: Compact (USB), Standard (USB, PoE or Wi-Fi)
  • Rugged version is an upgrade available for all the camera versions

The HIGIA solution consists of 3 main elements

Higia thermal camera

High precision infrared camera based on a high sensitivity uncooled detector.


Temperature reference device

Field box with a low emissivity surface at a controlled temperature of 37 ºC (configurable). This device provides a temperature reference, controlled by a PID, to calibrate the camera in real time to achieve the best precision in every measurement.

Control and visualization PC

With the RedLook software application installed. Low resources computer required. The HIGIA Elevated Body Temperature functionality of RedLook analyzes every subject’s temperature and compares it to the previously specified threshold. If the subject’s temperature is above the threshold an alarm is generated.

Architecture diagrams
  • HIGIA can be integrated with third-party control systems as access control systems for an additional level of security.

  • The architecture diagram shows the possibility to connect several thermal cameras (including different versions) to one application computer.

High reliability thanks to

closed loop calibration

Outdoor and indoor performance keeping the highest reliability

HIGIA is a premium infrared thermography solution for Elevated Body Temperature detection providing a much better performance compared to apparently similar low cost solutions. The high added value points in comparison to the low cost solutions are the following:

  • Best-in-class rate of reliability with negligible false positives and false negatives

  • High precision and accuracy in the measurement. A real-time closed loop calibration using a controlled temperature reference allows to achieve a greater performance. Delivered with Calibration and Conformity Certificates.
  • HIGIA provides absolute temperature values while others just provide relative measurements between subjects. HIGIA thermal cameras are calibrated in laboratory using certified calibration patterns. No adjustment factors required.
  • High resolution and image quality. HIGIA thermal camera integrates high resolution detectors that provide a sharper infrared image.
  • Two different operation modes: Absolute temperature threshold (37.7 ºC, for example) and Average deviation threshold (+1ºC over the average of the last n readings)

  • Higia can operate at both outdoor and indoor conditions keeping the highest reliability. By this feature, the temperature measurement is not conditioned by external factors, even in hot or cold environments.

RedLook is implemented in SENSIA’s line of fixed systems for 24/7 monitoring. This comprehensive monitoring system presents innovative capabilities assembled under a single control software.

Higia performance lets RedLook to enable exhaustive monitoring and real-time alerting. Our software is highly versatile, allowing to configure several Regions of Interest (RoI) within the area to be monitored. And to each one of them, any functionality can be assigned, granting a total and safe surveillance of the installation.
