Describe the integrated application of ATM monitoring from a technical perspective
Original: Shi Xinhua Source: Yuantuo Technology
With the rapid economic development, ATMs have become an indispensable part of people's daily lives. As ATMs penetrated into people's lives, ATM's own problems, the social security situation became more and more complicated, more and more crimes on ATMs became more and more serious, and the disputes between banks and customers also greatly increased.
Criminals use the drawer's own poor awareness to prevent the cardholder from peeping at the password when withdrawing money from the ATM, or draw the cardholder's attention, and collaborate with others to subcontract the bank card on the cardholder's ATM, and use the peeping password to steal To withdraw funds from the card, install an illegal card reading device at the ATM card slot, or rob and intimidate the drawer to withdraw money in the area of ​​the ATM.
At present, ATMs adopt a security prevention and control system represented by video surveillance and alarm linkage, which is almost reduced to a tool for providing evidence recording afterwards. The alarm information cannot be provided in time at the time of the incident, and such crimes cannot be effectively curbed.
Nanjing Yuantuo Technology Co., Ltd. focused on the above security problems of the current ATM ATMs and concentrated its technical strength to develop an ATM ATM intelligent anti-theft card system. After a long period of testing and application, the system has been fully improved to achieve The teller's cash is safe, and the bank card information is peeped and leaked to protect it effectively and reasonably.
Yuantuo Technology's ATM anti-theft card system intelligently analyzes the ATM card slot in a certain area in front of the ATM. The ATM intelligent anti-theft card system has been successfully applied in some cities in China. Before the World Expos in Beijing, Nanjing and Shanghai, the above-mentioned ATM intelligent anti-theft card processing products were installed on ATMs in Shanghai and connected to the ATM monitoring and networking system in Shanghai. The intelligent anti-theft card networking monitoring of these ATMs was greatly improved The original monitoring performance has been well received by users.
Main technical features:
First, multi-point ranging is performed on the card reader of ATM machine and other self-service equipment and its surroundings through a high-precision laser ranging system, and the measurement result is saved as a reference value. During normal operation, the card reader of the self-service equipment such as ATM machine is repeatedly measured according to a certain period or preset conditions, and compared with the measured distance value received and the stored reference value, when the measured distance value does not exceed the alarm When the distance parameter value is maintained, the current state is maintained; when the measured distance value exceeds the alarm distance parameter value, it means that the physical state or shape around the reader has changed, then an alarm signal is sent to the control module, and the continuous alarm time is counted If the continuous alarm time statistics exceed the set warning time parameter threshold, the control module will send out warning instructions, warning warning signals, voice prompts and on-site pictures through the Internet of Things module, and will not act on normal card actions Will produce false positives;
Yuantuo anti-side recording system uses a phase-type laser ranging module to achieve high-precision laser multi-point ranging. A laser protective net can be formed around the card reader. Because the device is hoisted at a certain distance in front of the self-service device, it is not only convenient to set up, but also has good concealment. And without destroying self-service equipment, the installation position is flexible, and can be installed within a distance of 0.05 meters to 20 meters from the ATM machine reader; in addition, the laser light path of the device not only has a large detection range, but also is not easily affected by the environment and electromagnetic interference Solve the problems of false alarms and omissions of traditional equipment.
The Internet of Things module is specially set in the system, which can monitor the card slot status of the ATMs of each network point in real time through the central network, and can report to the center in time for any abnormal conditions of the card slot. At the same time, it can be connected to the SMS alarm module to send SMS alarm to the relevant personnel or the SMS alarm platform of the public security department.
ATM monitoring system:
Behaviors that trigger system alarms include:
â‘ Except for the cardholder who normally operates the deposit / withdrawal of the ATM machine, an alarm is triggered when other personnel enter the preset monitoring area. Including all body access and part of the body access (hands, feet, head, etc.).
â‘¡Except for the cardholder who normally operates the deposit / withdrawal of the ATM machine, an alarm is triggered when there are other people wandering near the preset monitoring area.
â‘¢When there are more people gathered in the monitoring area in front of the ATM machine, there is suspicious behavior such as fighting or destroying the ATM cabinet, etc., an alarm is triggered.
â‘£ When the person approaches the ATM, the human body approaches the alarm pre-recording and the delayed recording function after the human body leaves.
Compared with traditional monitoring methods, Yuantuo Technology's ATM intelligent monitoring system has the following advantages:
â‘ No need for monitoring personnel to watch a large number of screens at the same time for a long time. With the help of the powerful data processing function of the computer, the data in the video screen can be automatically analyzed at high speed to filter irrelevant information.
â‘¡The incident responded quickly, and early warning before the occurrence of criminal behavior, notify security personnel, and respond in a timely manner.
â‘¢Intelligent selective storage, saving massive storage space. For example, it can be set to automatically turn on the video storage function when someone appears in front of the ATM machine, and turn off this function when there is no one.
â‘£Intelligent video retrieval, it is simple, easy and fast to check previous videos.
⑤ With the panoramic map server system independently developed by our company, it can be more intuitive, clear, and quickly obtain the real-time information of each ATM in the map area.
In short, the anti-theft code system based on the new generation of early warning and prevention theory is an effective supplement and development of the traditional video surveillance system. Its appearance greatly avoids improving the bank's defense capabilities, changing the traditional single video surveillance idea, and making full use of various sensors to establish a complete system of frontier warning, on-site deterrence, equipment security, case control, and power delivery. It is of great significance to combat professional crimes of ATMs, protect the interests of cardholders, maintain the social image of banks, and guarantee the order of financial payments.
