With the high incidence of ATMs in recent years, various commercial banks have strengthened video surveillance measures for ATMs and installed professional monitoring systems. However, due to the particularity of ATM monitoring, many common monitoring fields have not been found. Problems have caused a lot of confusion for banks and engineering companies. In order to facilitate relevant users to further improve the system, improve the monitoring mode, and better play the unique role of ATM monitoring, here are some common problems and some solutions.
Question 1: Which areas are mainly monitored by ATM monitoring? How many cameras are needed?
Answer: Generally, the front of the person is monitored, the cash outlet, and the cash distribution area. The front camera of the person is mainly used to obtain the front image of the withdrawer or the spoiler. The camera mainly monitors the moving images during the banknote distribution process. Among them, the camera in the banknote outlet and the banknote distribution area generally adopts automatic switching mode, so the real video recording is two-way, but three cameras are required. However, with the changes in the financial security situation, in recent times, public security departments in many places have proposed the requirement of installing 5 cameras. This requirement is mainly for the monitoring of the surrounding environment of the ATM, that is, the need to add two environmental cameras (each Ambient cameras cover 90 degrees and two channels cover 180 degrees) to achieve panoramic coverage and prevent monitoring of dead ends, providing more comprehensive evidence for the forensics afterwards. In this way, 5 cameras need to be installed, and the actual recording is 4 channels.
Question 2: Why do the images in the keyboard password area have a blocking function?
Answer: Due to the special structure of the teller machine, most of the camera of the cash outlet will monitor the keyboard image of the ATM machine, which will cause the image of the input password to be recorded. Be blocked to avoid leaving security holes in the future.
Question 3: In addition to superimposing the time, date, etc., why should the bank card number of the beneficiary be superimposed on the video image? How to obtain the card number?
Answer: This is mainly due to several reasons. 1Only the bank card number is superimposed on the front image of the person who withdraws can directly prove that the person withdrew the money, which provides the most direct and effective evidence support for the court to obtain evidence in subsequent disputes; 2 Superimposing bank card numbers also provides an aspect for future video retrieval, otherwise it is also very troublesome to find the video of the dispute card in a few months of video.
Since the acquisition of bank card numbers has involved financial security issues, most of them now use special hardware to read from card readers, and the form of network access to card numbers has been banned by banks.
Question 4: Why do some banks need to install SMS alarm module?
Answer: Due to the instant, economical and convenient characteristics of SMS alarm, when the vandalism occurs on the teller machine, it can be transmitted to the mobile phone of the relevant personnel as soon as possible, which provides the possibility of handling the problem in a timely manner.
Question 5: Why should I install an emergency help button on the ATM machine? What function should the button have?
Answer: Due to the special nature of the withdrawal environment, when the withdrawal person feels danger or needs help during the withdrawal process, he can press the emergency button installed on the ATM operation panel in a convenient and concealed manner, and call the bank security personnel to handle or trigger the relevant sound. The light alarm device can prevent possible vicious events in a timely manner. This button can improve the bank's ability to prevent it, thereby better maintaining the bank's reputation.
The buttons generally have functions such as intercom, automatic announcement, and triggering alarm device.
Question 6: How to solve the problem of monitoring host crash?
Answer: Whether it is embedded or industrial control monitoring host, there have been problems of crashing and not recording in the actual use process, which has caused many cases to be unable to obtain evidence.
From a product point of view, there is no absolutely perfect product, and the factors that cause the monitoring host to crash are also very complicated. In many cases, it is normal to turn off the power and turn on again after a crash is found. Due to the special nature of ATM monitoring, the vast majority of monitoring hosts are in an unattended 24-hour working state. Considering the security issues, most banks do not allow ATM monitoring systems to access the bank's business network. late.
Solution: install a host status monitor, automatically cut off the power of the monitoring host and reconnect when there is a crash, if it can not be restored, trigger the alarm device to notify the maintenance personnel to repair in time.
Question 7: What trigger recording method is generally used for ATM monitoring?
Answer: Mainly trigger recording by human activity monitor, vibration sensor, and banknote distribution sensor, supplemented by recording triggered by image motion detection.
Question 8: What should I do if the front camera of the person is partially blocked?
Answer: Due to the widespread installation of ATM monitoring, many criminal suspects also know that a monitoring system is installed on the teller machine, and they also know that all the cameras are blocked, and the system will alarm. Recently, a part of the cameras has been blocked in many places, making the monitoring system lost. effect. For this new type of criminal tactics, a combination of human activity monitor + image motion detection can be used.
Question 9: Why is it necessary to combine the front image of the person and the image of the cash outlet into one image when recording?
Answer: If you record independently, there will be many disputes in the future when the court obtains evidence. It is more direct, reliable and effective to combine the frontal image of the person and the image of the cash outlet into one image as evidence, without the need for dispute reasoning.
