Our Business

Wide Area Surveillance 

HGH’s SPYNEL 360-degree thermal imaging systems take Wide Area Surveillance to the next level. On land or at sea, the SPYNEL thermal cameras acquire high-resolution 360-degree images, with automatic and real time detection of simultaneous and unlimited number of targets. The SPYNEL cameras continuously monitor ultra wide panoramic fields of view to ensure that no event is missed, even in total darkness, or through smoke or inclement weather conditions. SPYNEL, equipped with the CYCLOPE advanced detection and tracking software, is the ultimate solution for 24/7 situation awareness, providing unprecedented real-time security for critical infrastructures.

Test & Measurement 

HGH provides leading-edge IR test equipment, ranging from blackbodies and collimators to integrated test benches, to universities, research labs, detector manufacturers and test centres around the world. Beyond the quest for technical excellence, we strive to offer a complete metrology service to our customers, by sharing our experience and best practices, offering expert support, trainings, and commissioning for our integrated solutions.

Industrial Thermography 

HGH manufactures thermal scanners and cameras for remote temperature measurements on rotary kilns, with the highest accuracy. HGH solutions extend equipment lifetime and enable maintenance actions before irreversible damage occurs. It contributes to improving production in quality and quantity, with a reduction in downtime and energy consumption. HGH has sold more than 1000 units worldwide.
