Olho Vivo Patrol

The proprietary Aretron OCR engine processes vehicle license plate images in real time, directly on the hardware embedded in the vehicle. High-resolution lateral cameras capture plates on both sides of the road simultaneously, even at speeds up to 60 km/h, in rain, at night, or with intense solar reflections.

The system processes between 3,000 and 5,000 plates per hour in normal urban operation. Each reading is instantly cross-referenced with the local database (Blue Zone, restricted vehicles, SINESP alerts). The 98.7% accuracy is achieved through specific training with Brazilian plates in both old and Mercosur standards.

The urban stewardship module uses computer vision to automatically identify and classify pavement defects (potholes, cracks, undulations), worn horizontal signage (faded lanes, unpainted speed bumps), and damaged vertical signage (crooked, illegible, or missing signs).

Each detected defect is georeferenced with centimetric precision and classified by severity according to DNIT criteria. Continuous mapping allows the city to prioritize maintenance based on objective data, eliminating dependence on complaints and manual inspections that took weeks to cover the entire city.

The accessibility module automatically maps the city's inclusion infrastructure: access ramps, tactile paving, accessible parking spaces, curb ramps, and audible traffic signals. The system identifies both the presence and the absence or deterioration of these elements.

The data feeds a compliance dashboard based on ABNT accessibility standards, allowing city management to prioritize inclusion investments using georeferenced evidence. Automatic reports are generated for accountability and budget planning.

The Olho Vivo Patrol facial search module uses the proprietary AreaFace engine, built with proprietary technology for optimized processing on dedicated hardware. The system captures faces in real time through the vehicle cameras and instantly compares them against databases of wanted, missing, or arrest-warrant individuals.

Native anti-fraud protection detects spoofing attempts using photos, videos, or 3D masks. All processing happens locally in the vehicle, with no biometric data sent to the cloud.

AreaChain is the Areatec immutable record system that ensures the digital chain of custody for all evidence produced by Olho Vivo Patrol. Each record (photo, plate reading, GPS coordinate, telemetry data) receives a unique cryptographic signature at the moment of capture and is stored immutably.

This makes it impossible to alter, delete, or forge any evidence after its creation. Traceability is complete: any audit can verify the integrity of a record from the moment of capture to final processing.

The PTT (Push-to-Talk) over IP communication system is proprietary to Areatec and runs over cellular infrastructure (PoC), removing the need for conventional radios and their range limitations.

An exclusive differentiator is AI voice analysis: Aretron interprets the field agent's vocal tone, detecting signs of stress, fear, or risk situations, and automatically alerts the operator at the control center.
