Rahm Sensor Development builds FDA-registered, AI-powered radar and vision systems that protect human life without wearables or invasive surveillance.
Our flagship devices—Cell-Guardian™ for corrections and Silver-Guardian™ for elder care—combine radar, thermal, and video (RGB or infrared) sensing with on-device AI to detect vital signs, falls, and distress in real time, delivering continuous awareness and superior privacy through intelligent, contact-free monitoring.
Every year, preventable deaths occur due to gaps in human monitoring—officers can’t watch every cell, and caregivers can’t reach every room. Traditional solutions rely on wearables, invasive cameras, or manual checks that compromise privacy or fail when devices are forgotten or refused.
Rahm Sensor Development addresses this critical need with contact-free radar, thermal, and intelligent video fusion processed entirely on-device.
Founded by Vik Ramprakash, who previously built and sold VetGuardian™ (acquired by Zomedica in 2023), Rahm adapts proven radar technology for human health and safety applications.
Flagship Products
- Cell-Guardian™
Provides continuous 24-hour monitoring of motion, breathing, and falls in correctional cells, enabling staff to detect distress events within seconds between mandatory checks. Early county deployments have already prevented potential incidents. - Silver-Guardian™
Extends the same radar-AI core to senior living and home environments, with infrared video for privacy-safe, night-vision monitoring and no cloud storage.
Both systems are FDA Class I registered, IEC 60601 pre-compliant, and manufactured in an ISO-13485 facility in Atlanta. Rahm owns core IP with patents filed on radar-AI fusion and behavioral classification.
Mission: No one should die unseen—whether in a cell or a senior’s bedroom.

Investment Opportunity
Rahm is raising $2.0 million via Seed-2 convertible note to accelerate commercial rollout and advance toward FDA Class II 510(k) clearance for vital-sign analytics.
The round bridges proven pilot traction to national scale in correctional and elder-care markets.
Use of Funds
| Allocation | Amount | Purpose |
|---|---|---|
| Manufacturing & Inventory | $800k (40%) | Scale production for 500+ units, fulfill >$2M backlog, reduce lead times. |
| AI & Firmware | $500k (25%) | Complete heart/respiration algorithms, expand datasets for 510(k). |
| Sales & Marketing | $400k (20%) | Grow distributor network (5→15 regions), build $5M pipeline, support pilots. |
| Regulatory & Working Capital | $300k (15%) | Maintain compliance, fund operations. |
12-Month Goals
- Ship >500 devices (>$1.5M ARR)
- File FDA Class II 510(k)
- Launch 3 retail pilots for Silver-Guardian 2.0
- Expand AI dataset to >10k hours
With $1.35M raised to date and paid revenue from pilots, this round positions Rahm as the leader in privacy-controlled, contact-free safety monitoring.
Rahm’s Guardian platform fuses 24 GHz radar, thermal imaging, and video sensing (RGB or infrared) with edge-AI for real-time detection of motion, breathing, and falls.
Key Features
- On-device processing: Cell-Guardian™ uses secure cloud for compliance; Silver-Guardian™ keeps everything local for privacy.
