The Smart G4 Simple Slave Economy Series delivers reliable, cost-effective GRMS for budget hotels, serviced apartments, and large-scale economy properties. The system uses a master–slave architecture: a master service requester panel at the room entrance communicates with slave bell units inside and outside the room, giving guests clear visual and audible DND and service signals without complex wiring.
The iconic large-format LED display shows the room number in bold red digits — instantly readable from the corridor — alongside DND and service request icons. Available in wall-mount and door-mount configurations, the Simple Slave series is the go-to choice for 2 and 3-star hotels that need professional GRMS at an economy price point.

The large-format red LED display shows the room number in digits readable from 10 metres down a corridor — no ambiguity for housekeeping, maintenance, or room service staff.
DND, Make Up Room, and service request signalling at a price point that works for 2 and 3-star hotels, serviced apartments, and large-scale budget properties without sacrificing reliability.

The Smart G4 BioHotel GRMS Series replaces every key card, PIN, and physical button in the guest journey with facial recognition and biometric access. From the moment a guest arrives at the car park entrance to check-in at reception, elevator floor selection, gym access, housekeeping verification, and room entry — every touchpoint is authenticated by face.
The system integrates directly with the hotel's GRMS, PMS, and access control infrastructure. Staff and guests are enrolled once at check-in; the biometric profile then travels with them across every access point in the property for the duration of their stay — no cards to lose, no PINs to forget, no contact required.

Guests and staff are enrolled once at check-in. Their biometric profile is instantly active across every access point — car park, lobby, elevator, gym, spa, and room — for the entire stay.
No key cards to issue, demagnetise, or lose. No PINs to share or forget. Every access event is touchless, logged, and tied to a verified identity — raising both security and the guest experience simultaneously.
Housekeeping, maintenance, and room service staff are verified by face before any room entry is authorised. Every access event is timestamped and logged for compliance, dispute resolution, and security audits.
Wheelchair users and guests with mobility limitations access every touchpoint — elevators, doors, amenities — hands-free by face recognition alone. No buttons to reach, no cards to swipe, no barriers.

Unlike fixed-function panels, the Mosaic Android platform is fully customisable — hotel branding, room type layouts, language preferences, and service menus are all configurable through the Smart G4 management console. The same hardware supports firmware updates over the network, future-proofing the investment across the property lifecycle.
