About Custom Model Building
How we became the team hardware OEMs trust for camera-specific rPPG models
Why Hardware OEMs Choose Us
We built Circadify's rPPG technology from the ground up — training models, deploying them on consumer devices, and learning what it takes to make vital signs extraction work reliably in real-world conditions. That production experience is the foundation of our custom model building practice.
When hardware OEMs and Tier-1 suppliers approached us, the pattern was consistent: generic rPPG models performed poorly on their specific cameras. Different sensors, different optics, different noise profiles, different deployment environments. The models needed to be trained against the actual hardware to perform. So we built a systematic process for doing exactly that.
Today, our custom model pipeline handles everything from automotive NIR cabin cameras to smart glasses micro-sensors to IoT health kiosks. Each engagement starts with your hardware and ends with a production-ready model optimized for your specific device, compute constraints, and target vital signs.
Our Mission
To enable every hardware platform to deliver reliable vital signs monitoring by building rPPG models purpose-trained for the cameras, sensors, and compute constraints of each specific device.
What Defines Our Custom Builds
Hardware-First Approach
Every engagement starts with your camera hardware, not our assumptions. We characterize your sensor, profile your compute, and build models that perform on your actual device rather than forcing your hardware to accommodate a generic model.
Production-Grade Delivery
We deliver models ready for manufacturing, not research prototypes. Production binaries, integration SDKs, validation reports, and technical documentation — everything your engineering team needs to ship.
Privacy by Architecture
On-device processing is not a feature — it is the architecture. Every model runs fully offline. Biometric data never leaves the device. This is non-negotiable and fundamental to every build.
Lifecycle Partnership
Hardware products evolve. Sensor revisions, new SoC targets, expanded vital sign requirements. We support custom models through your product lifecycle with retraining, optimization, and model updates as your hardware and requirements change.
