Portable Under Vehicle Surveillance System

The YD-GUVSS-R Portable Under Vehicle Surveillance System (UVSS) is a high-security inspection solution for vehicle undercarriage screening. Utilizing advanced linear CCD dynamic scanning technology, the system captures real-time, full-width, high-resolution undercarriage images. Designed to replace low-efficiency manual mirror inspections, it provides automated, reliable security screening at checkpoints, border crossings, and sensitive perimeters under all‑weather conditions.

Automated Trigger & Fast Image Acquisition
The system automatically detects and scans vehicles at speeds from 1 to 60 km/h (recommended ≤30 km/h). Once the vehicle passes over the scanner, a complete high-definition undercarriage image is displayed on screen in less than 1 second, ensuring smooth traffic flow at busy entrances.

Linear CCD Dynamic Imaging Architecture
Equipped with an advanced linear CCD scanner delivering an ultra‑high vertical resolution of ≥4096 pixels. Featuring an open wide‑field optical architecture with a 178‑degree field of view, it generates seamless underbody images up to 12000 × 7500 resolution, stored in standard BMP or JPEG formats.

All‑Weather Environmental Adaptability
Built to sustain a heavy‑duty load capacity of over 30 tons, the scanner accommodates a wide range of vehicles. Rated IP68 for waterproof performance, the system operates reliably in rain, snow, and harsh conditions. Working temperature range: -20°C to +60°C; storage temperature: -40°C to +75°C.

Intelligent License Plate Recognition (LPR)
Integrated with a standard 1‑channel LPR module (expandable to multi‑channel configurations), achieving single‑character recognition accuracy of ≥99% and total plate recognition accuracy of ≥95%. Average recognition processing time is <20ms, supporting plate image horizontal tilt angles from -10° to +10°.

Rapid Deployment & Intelligent Data Management
Designed for high mobility, the system requires minimal setup time and can be operated by a single person. The software automatically stores at least 10,000 images and deletes expired files. Users can easily retrieve stored undercarriage and license plate images by searching date, time, or plate number.

Military Bases & Government Facilities – Deployed at prison gates, customs checkpoints, and military perimeters to detect VBIEDs, hidden weapons, and unauthorized structural modifications.

Critical Infrastructure Protection – Provides perimeter defense screening for high‑risk assets including nuclear power plants, power grids, seaports, and airport access points.

Tactical Temporary Checkpoints – Ideal for rapid deployment at international summits, mass public events, and temporary border crossings – replacing manual mirror inspections in all‑weather environments.
