How it works



Rendered prototype of a Sereen device

Sereen devices are installed in the bedroom and living room.

No cameras, just radar

Bedrooms are very intimate places. As opposed to at-home cameras, Sereen preserves your privacy, only sharing information about your vital signs, but no images.

Hidden but everpresent

It works at a distance, detecting your vitals through clothes and without needing to touch or wear it.



The sensor tracks your health vitals and enables the device to diagnose you instantly if something goes wrong.

  • Heartrate

  • Breathing

  • Movement

  • Sleep

By tracking your heart rate over time we can understand whether there are irregular intervals or speeds that could be indicative of an emergency.

We track your breathing rhythm, inhale to exhale ratio, speed and frequency. This helps us understand if the body is under any kind of abnormal stress that could indicate an illness or medical issue.

By understanding what the usual patterns of movement to and from the bedroom and living room look like, we can detect when there has been a fall.

When we sleep, we move in different ways that can indicate whether there is a problem. We can detect issues such as sleep apnea.
