In recent years, various cases have occurred on ATMs all over the country, especially the rapid growth of ATM bank card cases since this year. Code piracy cases on bank ATMs have occurred in closely guarded Beijing, Beijing, and even Shanghai, where the World Expo is being held. From the perspective of the ongoing cases in various places, it is clear that the existing video surveillance system has not played its due role. The reason is that the entire industry relies too much on pure video surveillance systems, and video equipment providers and engineering installation service providers have exaggerated the effectiveness of video surveillance too much. Affected by this, various commercial banks and public security departments have also The focus of prevention and control inspections is on video surveillance equipment while ignoring other technical prevention and control methods. These factors ultimately lead to today's severe passive situation.

From a technical point of view, video surveillance does play an indispensable role in financial security, and it also plays an important role in the post-mortem forensics and detection of ATM machine cases. However, from the perspective of its efficacy, it can only play the role of collecting evidence after the event and tracing the source of the crime, but it does not have the functions of pre-warning and real-time prevention.

There is a problem

Although the relevant state departments publicize various methods of committing crimes on ATMs through various channels, it is also very difficult for ordinary cardholders to judge whether abnormal situations occur on ATMs of different brands and models. At present, in order to prevent crimes on ATMs, the investment cost of police force in some places is already greater than that of security equipment, but the effect is not ideal, and the social cost is very high. The resulting loss of the bank ’s reputation image even exceeds the bank ’s image advertising investment. In addition, many current ATM video intelligent monitoring will still have some shortcomings, mainly because the video intelligent analysis depends on many factors, such as whether the clarity of the image meets the minimum requirements for video analysis, and whether the image is subject to human interference (such as umbrella, helmet , Scarves, portrait masks, small pieces of reflective paper, etc.) or destruction, whether an illegal sticker with polarized light is used, whether the image analysis recognition algorithm is accurate, etc. Many conditions must be met at the same time to implement intelligent analysis, so the intelligent image recognition system Very ideal and demanding conditions are required, and in the actual ATM withdrawal environment, such conditions are almost non-existent, and there are not many intelligent video server manufacturers that can meet the above factors. The technology is stable and the functions are comprehensive. , Hanwang, Hikvision and other manufacturers.

solution

Change the traditional passive video surveillance ideas, give full play to the effectiveness of various sensors, establish a comprehensive prevention and control system based on sensor warning and video surveillance recording, and make up for the deficiencies of pure video surveillance system is the practical way to solve the current dilemma .

Judging from the types of crimes currently happening on ATMs, stealing trader ’s bank card numbers and passwords and cloning bank cards is the most difficult to see and prevent, and also the most harmful and worst-affected crime tactic. , Long latency period, large amount of money involved and other characteristics. Judging from the characteristics of this type of crime, there must be two elements: 1. Bank card number; 2. Bank card password. As long as these two elements are blocked, crime cannot succeed. The password is usually stolen by installing a camera. For bank card passwords, the location and method of installing the camera by the suspects are different (some even install a fake keyboard password anti-peep mask by themselves, and the fake anti-peep mask has a camera installed) , Difficult to prevent.

At present, the only way to steal a card number is to install a code stolen at the card slot of the ATM machine (the card access control system has been canceled explicitly). The code piracy is a physical device. After installation, it will inevitably cause the thickness of the card slot to change. As long as the thickness change at this position is measured by a dedicated device, it can be analyzed whether the card slot is abnormal. Because the laser has a very high measurement accuracy, even if criminals make the code thief very small, the laser distance sensor can be accurately identified. Through the laser ranging sensor, the thickness change of the card slot can be measured in real time. Once an abnormal change in thickness is found, an early warning can be issued through the Internet of Things module in order to stop and arrest the crime in time.

Yuantuo's anti-theft code system is independently networked to form a true Internet of Things, avoiding the disadvantages of incorporating video surveillance hosts (video surveillance hosts crash and instability is more common), even if the video surveillance host crashes, sensor warning The system is still able to exert its effectiveness, form a new monitoring model with diversified risks and centralized management.

TV Stand

TV Stand, also known as TV cabinet. TV cabinets are mainly used to place TVs. With the improvement of people's living standards, electrical equipment matching TVs has appeared accordingly, resulting in the development of TV cabinets from single to diversified use, no longer a single use for placing TVs , but the collection and placement of TVs, set-top boxes, DVDs, audio equipment, discs and other products.

Combination style

The combined TV cabinet is a sublimation product of the traditional floor cabinet TV cabinet. It is also the most popular TV cabinet among consumers in recent years. The feature of the combined TV cabinet is the word combination. Decorative cabinets, floor cabinets and other household cabinets are combined to form a unique TV cabinet. When you put a set of TV cabinets composed of floor cabinets and wine cabinets in your living room, isn't it very eye-catching!

Shelf style

The characteristics of the panel TV cabinet are generally similar to the combined TV cabinet type TV cabinet, mainly because the material used is the design of the plate structure, which is more prominent in practicality and durability.
