Products Description

The Fixed Under-Vehicle Surveillance System (UVSS) is a permanent, military-grade checkpoint security solution integrated with a high-definition linear CMOS dynamic scanning architecture (≥ 4096 pixels). Engineered with a heavy-duty structural frame capable of sustaining an exceptional ≥ 50-Ton load-bearing weight, this ground-embedded system automatically delivers a massive >90-Megapixel high-fidelity visual blueprint of vehicle chassis in less than 1 second (<1s). Featuring cutting-edge AI intelligent identification (optional) for contraband detection and dual-layer IP68 waterproof protection, it is optimized for 365-day uninterrupted high-risk perimeter defense at international borders, military bases, prisons, and critical government infrastructure.

Product Advantages

High Resolution and Comprehensive Imaging

High Definition and Precision

Utilizes high-resolution line-scan cameras or sensors capable of capturing extremely clear and detailed images of the vehicle undercarriage, including minute structures such as screws, welds, and pipelines.

Seamless Panoramic View

Generates a complete, seamless panoramic image of the undercarriage, ensuring there are no blind spots and leaving no place for attachments or modifications to hide.

High Efficiency and Unobtrusive Inspection

Rapid Inspection

Vehicles only need to pass over the scanning area at a low, constant speed (typically 5-15 km/h), without requiring a stop, engine shut-off, or occupants to exit. This significantly enhances throughput at checkpoints.

Preventing Congestion

Particularly suitable for high-traffic entrances, effectively avoiding traffic jams caused by security inspections.

Automation and Intelligent Analysis

Automatic Threat Detection

Advanced systems integrate ATD software, which automatically compares the real-time scan image against a database of standard undercarriage images and highlights any anomalies or attached objects, assisting the operator in making quick judgments.

Reducing Human Error

Overcomes missed detections associated with manual inspections caused by fatigue, lack of experience, or negligence, ensuring consistent and objective inspection results.

Application Scenarios

Government and Military Sites
Preventing vehicle-borne bombs: This is the core function, effectively preventing bomb attacks against government buildings, leadership residences, and military command centers using vehicles.
Controlling material flow: Ensuring only authorized materials and equipment are brought into sensitive areas.

Critical Infrastructure
Ensuring energy and utility security: At locations such as nuclear power plants, dams, and power grids, it prevents saboteurs from using vehicles to carry explosives inside, thereby avoiding catastrophic accidents and widespread disruption.

Transportation Hubs and Border Crossings
Combating smuggling: Efficiently intercepting drugs, weapons, currency, and dutiable goods concealed underneath vehicles.
Preventing illegal stowaways: Detecting individuals attempting to sneak in by clinging to the vehicle undercarriage.
Ensuring aviation security: At airports, it is a key part of aviation ground security, preventing dangerous items from being brought into controlled areas like aprons and terminals via vehicles.
