Guest Experience. Unseen Security.
Discreet, high-performance security and networking solutions that protect guests and staff without disrupting the hospitality experience.
ZEI engineers hospitality infrastructure that protects guests and staff while staying invisible to the experience — mobile keys, discreet surveillance, distributed audio, high-density Wi-Fi, lone-worker safety, and back-of-house security. Designed for the operating realities of hotels, resorts, and restaurants.
Technology Partners
A representative hotels & hospitality environment of the kind ZEI engineers infrastructure for.
What this industry deals with.
- Guest experience cannot be compromised by visible security
- Lone-worker (housekeeping, room service) safety legally required in many jurisdictions
- High-density Wi-Fi expectations from guests of every demographic
- Back-of-house shrinkage and contractor access exposure
- Multi-property chains needing standardized operations across locations
Hospitality Technology
Enhancing the stay while securing the property.
Mobile Room Keys
Skip the front desk.
Allow guests to bypass check-in lines and unlock their rooms securely using their smartphones.
Discreet Surveillance
Watching without staring.
Low-profile, aesthetically pleasing cameras that blend into high-end architectural designs.
Staff Safety
Protecting lone workers.
Panic buttons and location tracking for housekeeping and room service staff working alone in guest rooms.
High-Density Wi-Fi
Five-star connectivity.
Enterprise networking to ensure fast, reliable internet access for hundreds of guests simultaneously.
How this gets applied.
Mobile room keys
Skip-the-line check-in with phones unlocking guest rooms, elevators, and amenity spaces (Salto, Assa Abloy, dormakaba integration).
Lone-worker safety devices
Wearable or app-based panic devices with real-time location for housekeeping and room-service staff, complying with state staff-safety laws.
Distributed audio and digital signage
Multi-zone audio for lobby, pool, restaurant, and event spaces with centralized scheduling and content.
Back-of-house operations security
Loading-dock surveillance, contractor access management, kitchen and storage monitoring, time-and-attendance integration.
Systems we typically deploy.
An opinionated, ordered stack — what most hotels & hospitality engagements include, in priority order.
Access Control
ZEI deploys cloud-managed and enterprise access control across single-door deployments and multi-site campuses
Video Surveillance
ZEI engineers commercial video surveillance systems built around modern IP cameras, edge AI analytics, and cloud or on-premise video management
Commercial A/V
ZEI designs and integrates commercial audio-video systems that work the first time and every time after — Microsoft Teams Rooms and Zoom Rooms, distributed audio and digital signage, sound masking, and acoustic treatment, all centrally managed and serviced by our team
Networking & Wifi
ZEI engineers commercial network infrastructure that the rest of your facility depends on — structured cabling, managed switching, Wi-Fi 6E / 7, next-generation firewalls, and SD-WAN
Intercom Systems
ZEI deploys IP and SIP-based intercom systems that connect entry stations to mobile apps, desk phones, and security operations — bringing visitor management, video, and access control into a single workflow
Physical AI
ZEI deploys physical AI — computer vision, behavioral analytics, and machine learning — that turns existing camera infrastructure into intelligent sensors
Built to the standards that apply.
State hotel-worker safety laws
Florida, Illinois, New Jersey, and other states require panic devices for hotel staff working alone in rooms.
PCI DSS
Surveillance and access controls around card-present payment terminals.
ADA accessibility
Access systems support accessible alternatives for guests who cannot use mobile credentials.
Property Areas
Different security postures for different zones.
Guest Facing (Front of House)
Lobbies, corridors, and amenities.
- Aesthetic camera designs
- Pool & gym access control
- Luggage room security
- Valet tracking
- Seamless Wi-Fi roaming
Operations (Back of House)
Kitchens, loading docks, and staff areas.
- Inventory shrinkage control
- Time & attendance integration
- Delivery bay surveillance
- Food storage temperature alerts
- Contractor access management
