Single devices have limited value; linkage is the key
When access, elevator, fire and parking stand alone, experience fragments and operations scatter. The system-integration solution uses a platform as the hub, unifying heterogeneous subsystems into one policy and one data set, turning passage, security and emergency from silos into coordinated linkage.
Core capabilities
Fire linkage. Fire-alarm signals trigger access emergency release, turnstiles held open and elevator recall, keeping evacuation paths clear.
Elevator linkage. After gate verification, permission syncs to the elevator, auto-delivering to authorized floors, preventing floor hopping.
Parking linkage. Pre-registered visitor plates are auto-released at entry, closing the loop with personnel passage.
Open APIs and SDK. Standardized interfaces support secondary development and integration with HR attendance, property ERP, DingTalk, WeCom and more.
Integration with existing systems
The solution emphasizes openness over lock-in: API, Webhook and event bus connect existing HR, ERP and IoT platforms, protecting customers’ prior investment and avoiding rip-and-replace. For large groups this decides whether multi-subsidiary, multi-system unified control can land.
Privacy and compliance
Cross-system data flow needs minimal authorization and encrypted transmission; biometric and personnel data comply with PIPL; third-party connections must define data boundaries and responsibility.
Selection and deployment
Openness. Whether real open APIs and SDK and successful integration cases exist is the first selection question.
Architecture. Event bus and edge coordination decide linkage real-time and reliability, superior to point-to-point hardwiring.
Gray capability. Large-system rollout should support canary and rollback to avoid one-shot switch risk.
ROI
Value from protecting prior investment, unified operations and emergency coordination; risk from lock-in. For large customers with coexisting systems, integration capability is itself the selection watershed.
