As important windows for the country's opening up to the outside world, customs ports and bonded areas have large cargo throughput and complex vehicle types (truck collection, dangerous chemicals vehicles, cold chain vehicles, private cars, etc.). They are high-risk areas for smuggling, smuggling, and contraband. However, the traditional undervehicle security inspection model is facing severe challenges: the undervehicle blind area is large, making smuggling and hiding difficult to prevent: criminals use the hidden space under the vehicle to hide smuggled goods (electronic products, luxury goods, drugs), and illegal personnel even modify hidden compartments. Traditional manual inspection relies on mirrors or on the ground to see. Due to limitations of light and angle, the missed detection rate is as high as 30%, and it is easily evaded by experienced smugglers. Customs clearance efficiency is low and logistics costs are high: manual undercarriage inspection takes 3-5 minutes for each vehicle. During peak periods, serious congestion is caused at the checkpoint, and vehicle queues are several kilometers long, seriously affecting logistics turnover efficiency and corporate operating costs. Some advanced ports have achieved "second-level customs clearance", while many bonded areas are still in the artificial era of "squatting next to the car and checking documents." Nanjing Soan Electronics tailor-made the solution of "high-definition imaging + intelligent comparison + full-process marking" for the bonded area to achieve "non-stop vehicles, immediate hidden dangers, and second-level release." The dual-mode underbody inspection system performs complete chassis scanning imaging and real-time video monitoring of the vehicle chassis.

Binding license plate and image: The system automatically recognizes the license plate number, names the high-definition large picture of the vehicle under the vehicle as "license plate + time", and can optionally associate the driver's face, driving license, customs declaration form and other information to form a complete chain of evidence. Historical image comparison: The software supports retrieving differences in historical chassis image comparison of the car and discovering new caches or chassis changes. All-round synthesis display: Optional software can synthesize multi-angle images in front of, behind, under, and side of the car into a large picture, and visually display the "normal/abnormal security check" status on the interface. Multi-device linkage: The intelligent controller provides rich IO interfaces, which can link road gates, roadblocks, traffic lights, LED screens and voice broadcasts. Process automation: license plate recognition → underbody scanning → automatic lifting of the pole in normal cases; sound and light alarms, roadblocks are raised, and pop-up windows prompt re-inspection in abnormal cases. Permanent data storage: All images and associated information are permanently stored in the database, supporting multi-dimensional retrieval by time, license plate, unit, etc., providing ironclad evidence for anti-smuggling cases. Nanjing Suoan Electronics understands customs and business: it is deeply involved in the construction of under-vehicle security inspection projects in most bonded areas and ports across the country, is familiar with customs inspection processes and regulatory requirements, and is closely related to actual combat design. Leading technology and independently controllable: With independently developed high-speed line-scan imaging core technology and AI comparison algorithm, product performance reaches the international leading level, supports deep customization, and ensures data security. Extreme environmental adaptability: The product has been strictly tested to adapt to complex environments such as high salt fog, high humidity, extreme cold and scorching heat in the bonded area, ensuring stable operation for 7×24 hours and a long maintenance-free period. Turnkey engineering services: Provide one-stop services from on-site survey, scheme customization, system integration, standardized construction to after-sales training to ensure high-quality project delivery and help the bonded area successfully pass customs acceptance. Helping "smart customs" and jointly building efficient bonded zones Today, when trade facilitation and safety supervision are both emphasized, Nanjing Soan Electronics is willing to use leading undervehicle video intelligent monitoring technology to build an "invisible but powerful" security line for your bonded zone., achieve the goal of "manageable and fast access", and help optimize the regional business environment and high-quality economic development.
