Customer Background
Police stations, police substations, case-handling zones, government service halls and grassroots governance centers need controlled entry/exit, traced visitor registration, key-area access, anomaly alarms, data reporting and unified device O&M. The existing backend already has devices, readers, people, credentials, rights groups, visitors, logs, alarms, OTA, print and reporting — packageable as a complete smart passage and visitor closed-loop system.
Pain Points
Paper visitor logs. Outside visitors registered by hand at the desk — easy to lose, hard to trace, impossible to report.
High key-area risk. Case-handling, evidence and archive areas with single-credential passage risk over-rights and mis-open.
No anomaly loop. Door-magnet anomalies, open timeout, illegal swipes lack unified alarm and disposition records.
Scattered O&M. Device status, firmware versions and reader management are scattered, costly to triage on site.
DejaOS Solution
Device end. Face terminals, controllers, readers, door magnets, relays and alarm inputs cover gates, halls, offices, equipment/archive/case areas.
Backend. Unified people, org, devices, rights, visitors, credentials, logs, alarms, firmware and print config.
Mobile. Visitor booking, officer confirmation, face enroll, temp-code push, visit reminders and mobile approval.
Visitor side. Name, phone, ID, address, plate, purpose, host, captured photo and verify status into a traceable ledger.
Security side. Door-magnet, abnormal open, open timeout, repeated fail, tamper, interlock, unauthorized swipe, wrong PIN, duress-code alarms and audit.
O&M side. Device monitoring, reader management, config QR, firmware package and batch OTA, online check and secure MQTT.
Anomaly disposition. Events to backend alarm records, alert to duty end, disposition with photo/person/credential into exportable logs.
Expected Business Value
Passage closed-loop. Links internal passage, visitor log, key-area control, anomaly trail, visitor printout and data interface into one deliverable, not a single device.
Traceable security. Every entry, anomaly and remote op is logged, meeting accountability for case/evidence/archive areas.
Fast landing. Existing backend lets one station pilot then replicate to many, extending to justice offices, governance centers, service halls and park security.
Supervision linkage. Visitor info, logs, key-person flags and verify results report to police/governance platforms per project, feeding duty boards and remote O&M.
