Patent attributes
Multifunction smart door devices may be part of a system of multifunction smart door devices installed within or near stateroom doors of a cruise ship. Each smart door device can control access to a stateroom based on facial recognition or a wireless credential and can perform other functions such as controlling stateroom personalization features, providing an electronic peephole function, allowing controlled access for authorized crew members, accommodating remote unlocking, and providing notifications. Data obtained by the smart door devices can be provided to the cruise operator for service, safety, or security purposes, such as for anonymized foot traffic analysis, hazard detection, and stateroom access auditing. Smart door device functionality may be implemented in part by customers' mobile devices.
