Integrated Health Cam Device

I’m putting together a proof-of-concept that fuses a cardiorespiratory and pulse-oximeter module with a video camera, speaker and microphone—all inside a single enclosure. Its core job is continuous health monitoring, so the sensors must capture both heart rate and SpO₂ in real time and feed that data to an onboard processor for display or wireless transmission.

Because I also need visual context, the camera has to handle live streaming and local recording at the same time. Think of a patient pressing a button, the feed goes out instantly to a caregiver while a copy is stored on removable storage or flash for later review. The built-in mic and speaker will let users ask simple questions (“What’s my oxygen level?”) and hear an immediate, spoken answer pulled from current readings.

What I’m looking for from you:
• A working prototype (breadboard or compact PCB) that integrates the chosen heart-rate/SpO₂ sensor, HD camera, microcontroller/SoC, audio codec, speaker and mic.
• Firmware capable of sensor acquisition, on-device data processing, voice prompts, and simultaneous RTSP/HTTP live stream plus H.264 recording.
• A minimal companion interface (mobile or web) just to demonstrate data display and camera feed.
• Full documentation: schematics, BOM, mechanical layout, and flashing instructions so the build can be reproduced and scaled.

If you’ve tackled embedded health tech or multimedia IoT projects before, let’s talk through component choices and the roadmap to a demo-ready unit.
