At the entrance of unmanned data centers/warehouses, access control intercom terminals areinstalled, enabling staff to enter by swiping a card, entering a password, or receiving remoteauthorization from the security center.Inside the data center/warehouse, a SIP Video Intercom &Broadcasting Gateway PA2S is installed, which can interface with external sensors to detectintrusion or fire alarms.Upon receiving an alarm, the corresponding lP camera screen will pop up,and actions can be taken according to the preset plan, such as: issuing deterrent announcements,controlling audio and light alarms, making phone calls to relevant personnel, or sending textmessages, etc. 87%

Scratches, collisions, occupied parking spaces, and various issues that prevent the barrier gates from opening and closing are common emergencies in parking lots. Therefore, a one-touchemergency assistance system remains a necessary feature in parking lots, and its role becomeseven more critical in unmanned parking facilities. When drivers encounter emergencies in theparking lot, they can use the installed help terminals at the entrance and exit, as well as within theparking area, to promptly contact the management center or administrators for remoteassistance. This can greatly enhance the user experience in unmanned parking lots, achieving fast(convenient service), accurate (precise problem identification), clear (effective communication)and zero (zero communication distance). Moreover, it can reduce the overall operational costs ofthe parking lot.

The HWD Campus lP Broadcasting and Intercom integrated System achieves interconnectivity andintercommunication among multiple subsystems such as intercom, broadcasting, access controlsurveillance, alarm, and office telephone, allowing for resource sharing and centralizedmanagement of each subsystem. This not only reduces system investment and maintenance costsbut also enhances regulatory efficiency and emergency response capabilities.

As the adoption of technologies like facial recognition, RFlD tags, and electronic paymentsbecomes widespread, the concept of "unmanned operation" is seeping into various sectors.

Smart lampposts are an essential component of smart cities, with governments implementing a series of smart street light and smart courtyard light projects. These projects provide smart lighting, WiFi coverage, 4G/5G micro base stations, one-touch emergency assistance, urban broadcasting, surveillance cameras, and micro environmental monitoring for municipal roads,tourist attractions, squares, and residential areas. They are seamlessly integrated with road lighting poles, meeting both the aesthetic demands of urban road construction and the functional needs of city management.

The HWD Smart Community Audio-Visual IoT System addresses the pain points in old residential areas related to access, parking, security, living, and environment. It achieves the intelligent application of spaces such as smart elevators, unattended parking lots, unattended pedestrian posts, building entrances and exits, public areas, and monitoring centers, bringing more convenient and efficient management as well as a safer and more comfortable living environment to community life.
