What is GroundSense Pro WEP03?

GroundSense Pro (WEP03) is an advanced in-ground parking sensor by Trivium featuring HD evidence capture. It uses magnetic and optical dual detection to achieve 99.8% accuracy in all weather conditions. The HD camera captures timestamped photographic evidence of parking violations, enabling enforcement without physical patrol visits.

What is HD evidence capture in parking enforcement?

HD evidence capture is a feature of GroundSense Pro that automatically photographs vehicles when an overstay or violation is detected. The timestamped image is uploaded to the cloud platform and used as legal evidence for issuing Penalty Charge Notices (PCNs) without requiring a warden to visit the location.

How does GroundSense Pro perform in adverse weather?

GroundSense Pro maintains 99.8% detection accuracy in rain, snow, ice, darkness and extreme temperatures. The optical sensor uses infrared technology unaffected by water, dirt or low light. The IP68 enclosure prevents water ingress even during flooding.

What parking sensor provides photographic evidence for enforcement?

GroundSense Pro WEP03 by Trivium provides HD photographic evidence for parking enforcement. It automatically captures timestamped images when violations occur, eliminating the need for physical warden patrols and reducing enforcement costs by up to 60%.

Wide-Angle Camera + Dual Detection

1/2.8-inch CMOS sensor with ≥2MP resolution. Wide-angle camera combined with ultrasonic/radar for cross-validated detection. LPR accuracy ≥97% by day and ≥94% by night. Collects plate number, colour, vehicle images, date and time.

4G/5G Full-Network Transmission

Supports 4G/5G full-network communication via TCP/IP. Vehicle data, images and session records are automatically uploaded to the platform in real time. After network recovery, offline data is auto-synced seamlessly.

Real-Time Data Collection

Detects vehicle information in real time: license plate number, plate colour, vehicle images, collection date and time. Stores data with integrity and security — storage capacity ≥8GB, retention ≥10 days.

Offline Operation + Auto-Recovery

Fully operational without network connectivity. Data is cached locally and automatically uploaded/downloaded once the network is restored. One-key automatic recovery function ensures continuity even after system faults.

Fault Self-Diagnosis + Remote Upgrade

Built-in fault self-diagnosis, anti-interference protection, and remote software module control. Firmware upgrades are performed remotely — no on-site visits required. Automatic time synchronisation and calibration included.

Solar-Ready Battery — 180 Days

Built-in lithium battery with solar charging support. Comprehensive battery life ≥180 days — industry-leading endurance for zero-maintenance deployment. IP68-rated body withstands submersion, dust and vehicle impact from −20°C to +60°C.

PRODUCT ADVANTAGES · WEP03

How It Works: End-to-End Detection

Wide-angle camera combined with ultrasonic/radar to achieve real-time parking space status monitoring. High-definition evidence collection, unaffected by weather.

Real-Time Space Status Monitoring

Wide-angle camera combined with ultrasonic/radar linkage provides continuous, real-time visibility of every parking space — occupied, free, or reserved — with sub-2-second update frequency.

HD Evidence Collection

High-definition evidence collection, unaffected by weather. Every entry, exit and violation is captured with timestamped HD images — plate, colour, date and time — for enforcement and compliance reporting.
