Company Overview

IRay Technology Co., Ltd. (commonly known as InfiRay) is a massive global manufacturer of thermal imaging technologies and uncooled vanadium oxide (VOx) infrared focal plane detectors. Unlike companies that simply assemble cameras using third-party sensors, InfiRay physically engineers and manufactures the microscopic thermal sensor chips themselves, making them a titan in the global thermography supply chain.

During the height of global health concerns, InfiRay’s radiometric thermal cameras became omnipresent at massive live events, airports, and corporate campuses. Their specialized ‘Fever Screening’ systems utilize advanced AI face-tracking combined with highly precise thermal measurement. As hundreds of attendees walk into a venue, the camera instantly maps their faces and measures their inner canthus (tear duct) temperature, triggering a silent alarm if anyone exceeds a safe threshold, all without halting the flow of foot traffic.

Beyond fever screening, InfiRay’s massive catalog spans everything from heavy-duty industrial thermal drones used for inspecting event rigging and power lines, to ultra-compact smartphone thermal attachments used by touring AV technicians to spot overheating amplifiers in dark server racks.

Core Technologies

🔥

Proprietary VOx Detectors

InfiRay manufactures their own highly advanced, microscopic uncooled vanadium oxide thermal sensors, achieving incredibly high thermal sensitivity (NETD) to detect temperature differences of less than 0.04°C.

🧠

AI Facial Tracking

For crowd screening, their cameras do not just measure heat randomly; onboard AI instantly identifies human faces in a massive crowd, specifically targeting the forehead and tear ducts for accurate medical temperature readings.

🎯

Blackbody Calibration

To ensure absolute medical-grade accuracy (±0.3°C), InfiRay fever screening systems utilize a ‘Blackbody’—a separate device placed in the camera’s view that maintains an exact, constant temperature, allowing the camera to constantly calibrate itself in real-time.

Frequently Asked Questions

How can a camera accurately measure fever in a moving crowd?

Standard thermal cameras are wildly inaccurate for fevers. InfiRay uses AI to ignore hot coffee cups and only measure human faces. Crucially, they use a ‘Blackbody’ calibration tool in the background, which acts as a permanent, exact temperature reference point to keep the camera flawlessly accurate.

Can these cameras diagnose illness?

No. Thermal cameras are strictly ‘screening’ devices. They cannot diagnose illness; they only detect an elevated surface skin temperature. Anyone flagged by the system must be secondarily verified with a clinical medical thermometer.

Why do AV technicians use handheld thermal cameras?

Live events use massive amounts of electricity. A loose wire in a massive amp rack will generate immense heat before it catches fire. A quick thermal scan instantly reveals a glowing red ‘hot spot,’ allowing technicians to fix it before a disaster occurs.
