The Sirona M with SensorSafe monitors the well-being of the seated child through the smart chest clip that is synced with the installed vehicle receiver and the caregiver's smartphone; and while originally developed to help prevent the rising number of infant hot car deaths, the Cybex design of this technology has been expanded to ensure safety for children in a range of additional situations.

The Sirona M with SensorSafe still provides that essential alert when the caregiver accidentally leaves the child behind in the car, but also alerts the caregiver if a child unbuckles themselves while the vehicle is in motion; if the back seat has become too warm or too cold; and if a child has been seated for too long —all through a user-friendly app, that also provides guidance on installation, how-to videos, FAQ’s and other useful information to help prevent car seat misuse.
