product description:
　　 This product‘s under-vehicle safety inspection system can check whether the under-vehicle has been illegally altered to hide prohibited items or persons such as drugs and bombs. It can also detect places inaccessible to humans. In addition, this product has a high protection level design, which can work normally in harsh environments. The product is suitable for inspection of car chassis in airports, terminals, customs, prisons, military restricted areas, and other security inspection areas.
The vehicle bottom safety inspection system mainly detects the bottom of various vehicles, and can quickly and accurately find the prohibited items and illegal smuggling and private persons hiding under the vehicle. It is faster and more accurate than traditional vehicle inspection mirrors, which greatly improves the vehicle safety inspection. Speed ??and accuracy reduce investment in human resources.

Second, the scope of application:
1. Airports, prisons, customs and other government departments, and large public parking lot entrances and exits are used to check whether entering and exiting vehicles have prohibited items.
        2. Carry out safety inspections at the entrances and exits of large-scale events and exhibitions.
3. It is used for security inspection, explosion protection, and security inspection of the bottom of military vehicles.

3. Product features:
1. Adopt digital line scan camera, with extremely high image resolution and clarity.
2. Complete imaging of the vehicle bottom without any omissions, and the image is clear, complete and without distortion, and objects with a diameter of not less than 2mm can be clearly observed.
3. IP68 high protection level, anti-pressure and anti-vibration, suitable for use in any climate environment.
4. The inspection process can be compiled on site to meet various on-site needs.
5. Multi-channel scene image monitoring and recording functions.
6. Multi-language operation interface design.
7. Support image recognition or RFID technology for vehicle identification.
8. Extremely strong expansion ability, can easily realize the linkage control of various systems (such as: anti-collision system, barrier, etc.).
9. Support multiple devices network control function.
10. Inspection of image retrieval function: It can retrieve the stored bottom and license plate images according to the date, time, license plate number and other information.
11. Automatic image capture of the vehicle bottom: when the vehicle passes the vehicle bottom scanner at a speed of 1-60km/h, the system displays the image within 1S after the vehicle passes by. When the vehicle remains stationary within the image acquisition area of ??the vehicle bottom scanner After time passes through the vehicle scanner, the image of the vehicle is completely displayed.
12. Image automatic storage and deletion function: save no less than 10,000 pictures, and automatically delete the expired pictures.
