Manual Bottlenecks & Interception Delays
Field officers relied heavily on slow, manual radio lookups to check license plates. Every minute spent waiting for dispatch response allowed stolen or high-risk vehicles to escape tracking windows.

Vision
Real-Time Intelligence for Public Safety Operations
Operating within the high-stakes environment of public safety and military policing, field units require instant access to accurate vehicle data to enforce the law effectively. Vehicle sweeps, traffic checkpoints, and proactive patrols form the frontline of urban security, handling millions of data points daily across transit networks.
To transform this vital capability, the client partnered with Beno Support Technologies Pvt. Ltd. to engineer the Rota Legal platform. The ultimate vision was to convert continuous License Plate Recognition (LPR) camera feeds—from both fixed city checkpoints and mobile units—into instantaneous, actionable intelligence for officers on the move. By eliminating manual plate check delays, the system drastically increases the odds of intercepting stolen vehicles and flagging outstanding citations before suspects leave the area.
Challenges
Overcoming Infrastructure Vulnerabilities and Data Fragmentation
Traditional traffic operations and vehicle verification methods across Brazilian municipalities introduced intense operational bottlenecks. Key challenges included:
High-Volume Streaming Throughput
Continuous event streams generated by widespread LPR camera networks threatened to choke standard databases, requiring an ingestion pipeline capable of sustained, sub-second processing.
Patchy Field Connectivity
Mobile tactical teams frequently operated in areas with unreliable cellular networks, causing standard cloud-dependent applications to fail at critical operational moments.
Stringent Data Privacy Laws
Processing public vehicle transit records and linking plate numbers to owner information demanded absolute alignment with Brazil's General Data Protection Law (LGPD) without impacting system latency.
The Solution
Engineering a Real-Time LPR Intelligence Platform for Field Operations
Beno Support Technologies designed and delivered a fixed-fee MVP architecture centered on event-driven ingestion, offline-capable field apps, and LGPD-aligned identity workflows for public safety teams.
Multi-Tiered Application Refinement
Dual interfaces for officers in the field and command staff monitoring operations.
- Hybrid Mobile Application: Offline-first Flutter app for plate lookups, alerts, and checkpoint workflows under unreliable cellular coverage.
- Web Management Console: Operations dashboard for live camera events, hit lists, audit trails, and role-based team administration.
Event-Driven Pipeline & Legacy Integration
A high-throughput bridge between LPR camera listeners and actionable APIs.
- High-Performance Consumer (Golang): Sustained sub-second ingestion of dense LPR event streams via RabbitMQ.
- Enterprise API Layer (Java Spring Boot): Secure services for plate resolution, alerts, and integration with client-provided listener modules.
Security & Compliance by Design
Privacy-preserving plate handling without sacrificing operational speed.
- Layered Security Architecture: TLS, JWT/OAuth, MFA, and RBAC/ABAC perimeter controls across mobile and console surfaces.
- Hybrid Storage Model: Separates hot operational events from encrypted long-term identity records.
- LGPD-Aligned Data Minimization: Stores only fields required for enforcement outcomes with immutable audit logging.
De-risked Milestone Delivery Mode
A 5–6 week fixed-fee MVP window executed by a focused team of 3–5 engineers, with early integration of client listener modules and acceptance-gated milestones to keep delivery risk contained.
- 5–6 week fixed-fee MVP execution window with clear acceptance gates.
- Core architecture blended with client-provided listener modules from week one.
Measurable outcomes across architecture, compliance and delivery.

Business Outcome
The collaboration between Rota Legal and Beno Support Technologies Pvt. Ltd. transformed manual, radio-bound vehicle verification into a real-time public safety intelligence engine for Brazilian field operations. Dense LPR streams now resolve into actionable alerts that officers can trust under pressure.
By pairing an event-driven core with offline-capable mobile workflows and LGPD-aligned data handling, the platform shortened interception windows, reduced communication lag with dispatch, and established a repeatable blueprint for smart-city traffic enforcement.
