IR & Thermal Cameras
Custom rPPG for Infrared & Thermal Cameras
We develop custom rPPG algorithms for near-infrared and thermal camera systems — building preprocessing pipelines and training models from scratch for specific IR sensor characteristics, wavelength range, and thermal resolution.
Works in complete darkness. From active NIR illumination to passive LWIR thermal imaging, our custom builds extract reliable vital signs where visible-light rPPG is physically impossible.

What We Build
NIR Signal Extraction
Custom models for near-infrared (850nm-940nm) cameras that extract blood volume pulse from IR reflectance changes — fundamentally different physics from visible-light rPPG.
LWIR Thermal Processing
Algorithms for long-wave infrared thermal cameras (8-14 μm) that detect superficial blood flow patterns through thermal emission changes on the skin surface.
Complete Darkness Operation
Vital sign extraction in zero ambient light using active NIR illumination or passive thermal imaging — enabling 24/7 monitoring in any lighting condition.
Wavelength-Specific Preprocessing
Custom preprocessing tuned for your exact IR sensor’s spectral response, quantum efficiency curve, and noise characteristics at specific wavelengths.
Multi-Spectral Fusion
For systems with both visible and IR channels, we build fusion models that combine RGB and NIR/LWIR data for enhanced accuracy beyond what either modality achieves alone.
Hardened Deployment Packages
Production-ready builds for military (MIL-STD-810G), security (IP67/IP68 rated systems), and clinical (IEC 60601 environments) with appropriate environmental hardening.

IR & Thermal Camera rPPG FAQ
Common questions about custom rPPG for infrared and thermal camera systems
How does rPPG work with infrared cameras?
NIR cameras detect blood volume changes through IR reflectance variation in the skin. LWIR thermal cameras detect superficial blood flow through micro-temperature changes. Both require fundamentally different preprocessing than visible-light rPPG.
Can you work in complete darkness?
With active NIR illumination (invisible to the human eye), we extract vitals in zero ambient light. For passive operation, LWIR thermal cameras detect physiological signals without any illumination.
What military/defense applications do you support?
Personnel monitoring in field operations, night vision vital sign overlay, vehicle crew monitoring, long-range standoff vital sign detection, and mass casualty triage. All builds can be MIL-STD-810G hardened.
How do you handle multi-spectral camera systems?
We build fusion models that combine visible RGB, NIR, and LWIR channels. The preprocessing extracts complementary physiological signals from each spectral band, and the fusion model produces higher accuracy than any single modality.
What’s different about training models for IR versus visible light?
The physics of signal formation is different. Visible-light rPPG detects hemoglobin absorption changes via skin color variation. NIR detects reflectance changes at different tissue depths. LWIR detects thermal emission from superficial blood flow. Each requires purpose-built preprocessing, training data, and model architecture.
