When I was a kid, I heard that banks in foreign countries were even more than grain stores in China. Now taking a look at our current life, we can’t say that banks are innumerable, but ATMs almost exist everywhere throughout the country. The number of ATM is absolutely over the one of grain stores. It is a trend that ATMs shall be widely used. As common people, we should try to adapt to this high-tech product－-ATM and make it convenient for us maximally. To protect our benefits when using the ATM, it is very urgent to improve the functions of ATM surveillance.
Application of specialized alarm sensor in the banking surveillance industry
Sensing function: it has video motion alarm and dynamic tracking trigger recording function； it has detector input alarm and lens shielded alarm function as well as vibration alarm； when the ATM is under destruction, it will record and call the police； blacklist alarm function is also included, it can raise the local and remote networking alarm to the card number in the blacklist.
1. Human activity detector YT-EWS
It uses human activity detection way to record normal and exceptional transaction processes to avoid using motion detection recording way which causes numerous useless files.
It is widely used in the financial industry, Self Service Banking and human proximity alarm of ATM surveillance. It uses microcircuit chip as programmed processing which combines detection and control into one unit with high detecting sensitivity and triggering reliability. It has low stand-by power consumption, switch signal output and directly trigger alarm recording and is easy to operate.
Functions and features:
（1）Capable of penetrating walls and non-metallic doors and windows. It can be installed in a concealed built-in installation for ATM surveillance system.
（2）Detection distance is adjustable between 0 and 5 meters.
（3）The detection area is in the shape of a double fan.
（4）Dual detection technologies for low false alarm rate
（5）Robust for use in harsh environments. Detection sensitivity unaffected by temperatures between -20℃ and 80℃.
1. Vibration detector YT-SHK
It is a new vibration sensor with high sensitivity that developed for the ATM and Self Service Banking. It has omni-bearing detection, adjustable sensitivity and high anti-jamming capability. It is also featured with good consistence and interchangeability, small footprint, high reliability and low price.
Application of specialized camera in the banking surveillance industry
To prevent using ATMs to commit crimes, efficient security surveillance is very important. With the raising security surveillance consciousness, it is necessary to improve surveillance quality and reduce the degree of difficulties of collecting evidence. Due to the particularity of ATM surveillance environment, surveillance camera needs to be equipped with wide dynamic, high deficiency and privacy shielding function which can clearly see the faces and accurately reflect the corresponding situations on banknote output feed and banknote input feed and thus to guarantee that the whole withdrawal process is within the surveillance view range. This surely brings forward higher requirements to specified functions of surveillance camera. In this respect, mini-camera is more suitable for the particular surveillance demands of ATM.
The surveillance range of banking ATMs is very narrow and is largely affected by the illumination conditions. It has tight structure, small footprint and low consumption with higher quality and performance. Mini camera is more widely used in the banking surveillance industry, especially some banking ATMs with particular demands which ask the surveillance to have wide dynamic, high deficiency and privacy shielding functions. It has brought forward higher requirements to specialized performance of surveillance camera. With the wide application of ATM surveillance, the security and alarm manufacturers need to release mini cameras with higher quality and performance to satisfy the specified demands of banking surveillance.
Reducing the alarm failure in the intelligent video analysis.
Video analysis in the China security surveillance industry is in the early stage and the surveillance system needs to depend on intelligence to increase the thinking ability to take place of the surveillance staff 7×24-hour identifying exceptional events or states. Application of intelligent recognition on ATM is still at the starting stage. Facing with many technical bottlenecks, intelligent recognition relies on the support of HD cameras. Therefore, the development of HD development must lead the development of intelligent recognition. At current stage, first of all, “alarm failure” shouldn’t exist at all. Alarm failure is easy to be omitted whereas false alarm is common to see. Therefore, many manufacturers at home and abroad sacrifice the sensitivity to reduce the false alarm rate which causes high alarm failure rate. Professionals suggest that we should firstly pay attention to the alarm failure rate and tolerate some false alarm rate, and meanwhile, give the manufacturer certain time (for instance, 1 month) to solve most false alarms during the operation. The real demand of ATM surveillance should be “no alarm failure and low false alarm” rather than “low false alarm and high alarm failure”.
To strengthen the management ability
To set Internet of things module in the intelligent video surveillance can detect the ATM card slot in each Net-spot of banks in real time through central networking and every exceptional situation will be reported in time which can maximally protect banks and cardholders’ benefits. it uses multiple networking to add the 3G wireless warning transmission function. With the implementation of real-name registration, the cardholder’s cellphone number, name and serial number can be detected if this detection technology is applied in the ATM. Once the crimes happened, the suspect’s current position can be called through wireless communication technology and thus it will be easy to arrest the suspect.
Technical requirements of networking alarm and voice intercom
1. It is required that the system should have functions such as dual-net (TCP/IP private network and PSTN telephone) alarm, dual-net (TCP/IP private network and PSTN telephone) real-time voice telecom； in addition to the above two functions, the ATM surveillance host itself should add a peripheral equipment to achieve telephone alarm and voice telecom function (considering that most Net-spots of banks have no Internet conditions)； ATM front-end telecom equipment is required to have auto answer and auto hang up functions.
2. Telephone alarm is required to connect not only with the centralized management center of banks but also with 110 command center of Public Security departments.
3. To establish a dual-net (TCP/IP private network and PSTN telephone) centralized management platform which can use telephone to achieve alarm, voice telecom and SMS alarm management without the TCP/IP private network conditions. If it is under the condition of TCP/IP private condition, it can achieve dual-net alarm and voice telecom and transmit real-time images through TCP/IP private network.
4. It is required that when the local surveillance system is at fault or destructed or the network is cut, it can use the SMS alarm function to call the unified SMS alarm platform of public security departments and trigger the central alarm through the SMS.
With Xu Ting’s malicious withdrawal, improvement of customers’ awareness and complication of surveillance target, pitfalls of original relative specialized ATM surveillance system exposed constantly in practical application. At present, ATM surveillance modes at home and abroad are all under rapid development. In the current ATM surveillance background, Yuantuo Tech has already developed ATM-DVR towards more specialized, stronger networking, higher integration and intelligence.
