Basic Questions
How does FH Vitals™ differ from wearable devices?

Compared to traditional wearable devices, FH Vitals™’ contactless solution requires no additional hardware other than existing video cameras on your devices. FH Vitals™  offers a high accurate vital signs measurement with an intuitive operation, and can be used in a wide range of applications due to its flexible integration and adaptability to a variety of external settings.

What is the pricing model of FH Vitals™ SDK?

It depends on your use. Tell us about your case! Please fill out the form in Book a Demo and we will contact you shortly.

Where can I request a demo of FH Vitals™ SDK?

Please fill out the form in Book a Demo and we will contact you shortly.

What vital signs can FH Vitals™ SDK measure?

Available now: Heart Rate (HR), Heart Rate Variability (HRV), Blood Pressure (BP), and Oxygen Saturation (SpO₂), Respiration Rate (RR), Stress Index (SI). 

Coming soon: Atrial fibrillation (AF), Arrhythmia and Sleep Apnea.

How long does the measurement take?

On average, measuring your Heart Rate (HR) takes around 6 seconds, while your Heart Rate Variability (HRV), Respiration Rate (RR), Stress Index (SI), Blood Pressure (BP), and Oxygen Saturation (SpO₂) will be displayed consecutively after 34 seconds.

Can FH Vitals™ measure multiple people at the same time?

It depends on the processors' power and the camera specifications of the underlying devices. Usually, FH Vitals™ loaded on a handset can only measure one person at a time, while using a tablet can measure up to two people. It all depends on the CPU. In addition, for a typical 8-core ARM configuration (4x A73, 4x A53), FH Vitals™ can process 4 people simultaneously, and up to 6 people with stronger processors.

What is the effective range of FH Vitals™?

Depending on the hardware specifications, FH Vitals™ can measure one's vital signs from up to 5 meters away. 2 to 5 meters is typically applied to TV-related devices, although we need to adjust Lens Focus length to a certain proper value (such as 12mm) for this kind of devices.

Do I have to stare at the camera when taking a measurement?

No, it is not necessary to stare at the camera, but please place your face steady within the detection frame.

Does skin color affect the usage of FH Vitals™?

According to the Fitzpatrick skin type (,  FH Vitals™ can support up to type V (If it exceeds type V, the results depend on the surrounding environment).

What are the lighting requirements for using FH Vitals™?

FH Vitals™ can be used under most well-lit environments (Illuminance ≥ 150lux, Color temperature 3500K-6000K).

What are the minimum camera requirements?

VGA (640 x 480) is the minimum requirement. Frame Rate at 30 fps is recommended, and the minimum frame rate is 15fps.

Can I use FH Vitals™ with a regular RGB camera (typical WebCam)?


What are processors’ (CPU/GPU/NPU) requirements and computational power required?

For typical 8-core ARM configuration (4x A73, 4x A53), If GPU is available, it will be used during the FD and FR (Face Detection and Face Recognition) processes. NPU is not being used presently.

Has your technology gone through IRB approved clinical trials?

Yes, FH Vitals™ technology has gone through several IRB-approved clinical trials in six hospitals across multiple departments in Taiwan. The extensive clinical data collected during these trials have enabled FH Vitals™ to integrate doctors’ knowledge into our algorithm calibration measuring at medical-grade accuracy.

Can FH Vitals™ be used as a medical equipment?

FH Vitals™ is currently under application for FDA Class II clearance, which is expected to be approved in 2022.

Is it GDPR and HIPPA compliant?

FH Vitals™ merely displays the data and performs all its calculations on the edge, which alleviates any data privacy and security concerns.
