Stay Guardian by Engineer M8Smart access and privacy-first occupancy awareness
One package. One hub. Complete control.

Smart access meets property awareness.

Stay Guardian combines a connected lock box, Sense Guardian occupancy technology and one centrally located EM8 Hub—giving short-term accommodation operators a clearer view of every arrival, checkout and changeover.

The complete package

More than a smart key box

Stay Guardian brings guest access, occupancy awareness and property turnover into one easy-to-manage system.

Unique booking codes

Create time-limited access codes that activate for check-in and expire after checkout.

Privacy-first sensing

See whether the property appears occupied or vacant without installing indoor cameras.

One central EM8 Hub

A simple central installation removes the need for separate Wi-Fi hotspots throughout the property.

Checkout awareness

Know when guests appear to have left and identify possible overstays before cleaners arrive.

Cleaner access

Issue dedicated cleaner codes and build a reliable record of property changeovers.

Portfolio portal

Manage one apartment or a complete portfolio from a single online dashboard.

Operational clarity

Know what is happening without being inside the property.

A standard smart lock tells you a code was used. Stay Guardian helps connect that access event to the property’s occupied or vacant status.
