This device has 3 different types of alerts according to interpersonal distance:

> Distance less than 1m

-Flashing red LED.

-Beep sound (if not muted)

> Distance 1m-1.5m

-Flashing blue LED.

> Distance greater than 1.5m

-Flashing green LED. This is a safe distance and therefore is not a warning.

Social Distance Warning Device highlights.


This device doesn’t share personally identifiable information and location tracking occurs.


Detect physical contact from less than 5 cm up to 2m.


EPI-DWS prevents risky contact by alerting working before they get too close. This gentle reminder helps staff maintain social distance, even when focused on tasks.


With battery duration up to 10h.


Not smartphone and software are required for setup or operation.
