This article refers to the address: http://
With the rapid development of the financial services industry in the past few years, private commercial banks across the country have emerged, and their security and protection is related to social stability and people's property security. It has always been the focus of the development of the security industry. The banking industry has become one of the first industries to conduct digital video surveillance. A large number of surveillance cameras, video capture cards, information transmission equipment, DVRs and monitors have been applied to bank outlets, ATMs and vaults. monitor. The large-scale rise of the digital video surveillance system in the banking industry has promoted the rapid development of the security industry. With the improvement of the bank monitoring system and the development of digital technology, the bank's head office went to branches, branches to branch offices, and branch offices to the savings office. Remote monitoring is possible. In the future video surveillance market, the focus of technology will increasingly focus on digital, networked, intelligent, and integrated solutions. Banking monitoring system networking and intelligence will be an unstoppable development trend.
First, the importance of bank security monitoring
As a business place for financial services, banks are located in all corners of the city and belong to the country's key security units. They are characterized by diverse scales, numerous important facilities, complex personnel, and a wide range of management areas. As the main circulation place of today's social currency and an important part of the national economic operation, it serves a wide range of domestic industries with its unique functions and advanced technologies. Therefore, it is particularly important to improve the scientific and security capabilities of the banking system. As a business place for financial services, the security of its system equipment and the safety of its users have always attracted people's attention.
In order to contain and combat crime and reduce financial risks, banks need to effectively and reliably monitor important locations and business premises to achieve the preservation of audio and video data of important locations and business premises. The main purpose of the bank teller system video monitoring is to monitor the daily work of the recording counter staff, including the transaction process with the customer, reduce errors and disputes in the bank teller system, and provide for possible transaction disputes and other economic criminal activities. Video data and legal basis; ATM ATM monitoring ensures the safe operation of bank ATM, protects the interests of cardholders and banks, guards against various criminal acts against ATM, properly resolves disputes arising during the use of users, and adds them to ATMs. Install monitoring system to obtain accurate evidence of accidents, effectively protect the rights of banks and depositors, effectively prevent criminal activities such as financial fraud, and establish an efficient real-time surveillance video system has become an important management tool for banks.
Second, the composition of the POE switch bank monitoring passive transmission solution
Monitoring center workstation
Establish a unified monitoring and management platform to perform local and central multiple backup management of important information of the system to ensure the security of recorded data and other data.
Main operation terminal and display system: distribute images to the video wall, process information transmitted from remote sites, and control remote sites.
The alarm signal receiving system: receives the input of the access control and other alarm signals, performs corresponding encoding processing, and transmits to the management and video distribution server of the main control center.
Remote workstation
The remote workstation is a real-time, point-to-point video transmission system. With Internet/Intranet technology, users can use the remote workstation to access the system and receive video and alarm information transmitted by the network terminals of each monitoring point through the network to realize remote monitoring and maintenance. .
Front-end monitoring network
1. Counter monitoring---Monitor the salesperson's counting action, the face value and number of the bill, the working status of the money counter and the current customer's face, 25 frames/second. An emergency button can be added.
2. Business District Office Monitoring - Monitor the work of bank staff and customers in the interior.
3. ATM machine monitoring --- monitoring the use of customer behavior and face, 24-hour monitoring, password area for mosaic security.
4. Treasury monitoring---Monitoring all personnel, requiring a clear face, no blind spots, 24-hour monitoring, installation of an active double-infrared detector, and linkage alarm with the alarm access control.
Third, the design features of the program
With the network camera and network monitoring and management platform as the core, the pure digital monitoring system with POE switch as the transmission device has the following characteristics:
1, stable and reliable performance, no need to manage
The network camera is based on embedded technology and adopts embedded real-time multi-tasking operating system. The code is solidified in FLASH. The system is more stable and reliable. The network monitoring system using Tianshida network camera does not have the problem that the system can not operate normally due to machine crash. Stability and reliability are greatly improved, no need for special management, and it is very suitable for unattended environments.
2, installation is convenient and safe, management is simple and concentrated
The network video surveillance system greatly simplifies the types and quantities of equipment that may be involved in the monitoring system. It completely replaces the video matrix, switcher, picture splitter, character adder, etc. in the analog monitoring system, which not only reduces the construction of the debugging equipment. Cycles, while reducing the use of equipment, can improve the stability and reliability of the overall system, reducing the difficulty of maintaining equipment in the future. When you use it, you only need to enter the URL in IE to view the image. At the same time, the POE switch can not only transmit data and sound but also transmit power with the existing network cable, which can be used in combination with various security devices, greatly reducing the installation and Maintenance costs and centralized management. In addition, the PoE switch can mainly utilize the uninterruptible power supply system (UPS), and the safety is much higher after a long period of stable operation.
3, the image is clear and the bandwidth is low
Some network camera chips use the latest international H.264 compression method for image compression, which can use narrow bandwidth, over-frame reconstruction techniques to compress and transmit data. The compression ratio is up to 200:1. The server can also automatically adjust the stream based on the amount of bandwidth. Therefore, it will not increase the network burden too much.
4, high-performance systems with almost unlimited seamless expansion capabilities
The advanced nature of network cameras is the use of powerful video processing chips that deliver high-quality dynamic images at real-time speeds over 200 to 500 KB of bandwidth and support simultaneous access by multiple users. Under the LAN, you can allow unlimited users to access at the same time. Tianshida network cameras are identified by IP addresses. Adding devices means only the expansion of IP addresses.
5, can form a very large monitoring network
The network camera adopts the monitoring system based on the embedded network video server. The networking mode is very different from the traditional analog monitoring and PC-based monitoring. The network video server output has completed the analog to digital conversion. It is compressed and transmitted over the network using a unified protocol, so it supports remote video transmission across gateways and across routers.
6, remote system maintenance and system management
The webcam provides software access and remote web access. The administrator remotely manages system devices through software without having to reach the equipment site to improve equipment maintenance efficiency. At the same time, the administrator can modify the user information: remote addition, deletion, monitoring location, user control authority, recording time and alarm information. After the information is modified, the administrator does not need to maintain the client. The user only needs to log in to the system once again to get the information re-allocated by the administrator, which greatly reduces the software maintenance workload of the administrator.
Fourth, the program design

System topology
System topology
According to the monitoring environment and needs of the bank, we describe the monitoring system in two chunks. Bank outdoor monitoring area and bank indoor monitoring area.
4.1, bank outdoor solutions
At a distance of 5 meters around the bank, a video collection point is built and monitored by an infrared camera for 24 hours to achieve coverage. The POE network information point is arranged from the monitoring center of the building to solve the power and data of the base station, and may also be connected to the network in the vicinity according to the situation. The camera is waterproof and dustproof, and the lightning protection circuit ensures the safety of outdoor weather monitoring. Using SONY's latest SuperHADII CCD, ICR day and night conversion design, can also provide a clear picture in the low-light environment at night.
Automatically detect camera working status
Ensure that the video is destroyed (the video line is cut, the video source is cut off, the camera is damaged, etc.), and the alarm is promptly reminded to avoid recording unnecessary video or dealing with the destruction behavior in time;
Bank outdoor solution
4.2, bank indoor solutions
Bank hall
This area is an important area for banks to enter and exit, and is very important for the role of bank security monitoring. It is required to monitor the bank lobby 24 hours a day to ensure the safety of the bank. Even if the night lights are off, it provides a clear picture. Start wiring from the monitoring center room, go to the core switch, connect the POE power supply system, pull the POE cable to power the 6 cameras in the hall, install the camera ceiling, and cover the hall.
Bank hall
ATM area
ATM machine monitoring system, alarm processing two parts. The main purpose of ATM ATM video surveillance is to monitor the situation of each transaction, to provide video data to prevent transaction disputes or malicious overdrafts and other economic crimes, and to monitor the damage behavior of the ATM. Through the software, for different working states such as: monitoring, vibration, billing, and proximity, when the corresponding camera and video recording mode is used to sense strong vibration, the detector sends an alarm trigger signal to start the video recorder to record, and simultaneously pass the sound and light. The alarm device sends an alarm signal.
ATM monitoring
Teller area
The area is a key area of ​​banking business. The background of the tellers is generally a large glass wall with bright light. The request can see the face of the customer, and the whole process of the transaction can distinguish the denomination of the banknote. The business hall monitoring system consists of four parts: front-end equipment, transmission equipment, control equipment, display and recording equipment. The monitored objects include the daily work situation of the counter staff, providing video recording for banking management, transaction disputes and other economic criminal activities. The data, therefore, has high requirements for the clarity of the system video, recording time, video retrieval, system stability, convenience, and intelligence.
Fifth, the installation
Camera installation instructions
The camera is mounted on a 3 m high pole
Powered by 48V power supply, the connector of the POE cable connected to the camera should be wrapped with electrical tape. The base station should be well fixed and guaranteed to be neat and beautiful. The POE cable (twisted pair) is laid, and the Ñ„32PVC pipe is used. The wiring in the building is required to be close to the inner wall. It is fixed with a card code every 1 meter. The appearance is required to be clean and tidy, horizontal and vertical. If there is a need for bending in the cable routing, the elbow connection should be used. The bending radius requirement is not less than 8 times the diameter of the cable. Avoid bending more than 90 degrees and the cable is too tightly wound. Underground pipelines should be constructed with strong surface to prevent collapse
Power supply instructions
Unified power collection in the monitoring center, outdoor terminal only needs POE power supply, no need to take additional power
Grounding condition
The POE network cable must be connected to the lightning arrester. The lightning arrester needs to have lightning protection for the power supply and lightning protection for the network cable. The lightning arrester must be grounded.
Sixth, product selection

2, the transmission part (the PoE switch as an important device for network transmission)
PoE switches use UTP's leading HyperTransLRE technology, which not only can supply power, but also extend the distance, killing two birds with one stone and saving the total cost of TCO. And we use different equipment for different environments, follow the customer-centric principle, and use cost-effective equipment, such as indoor environment, in the case of solving problems, we use LS5004P.
Brief introduction of the transmission equipment:
The PoE switch is an important device for network transmission. It uses the LS5004P and LS5208PF of UTP Communication. PoE switches eliminate the hassle of deliberately connecting power outlets to these devices. Make connections to devices that are difficult to connect to AC power more flexible, and minimize installation costs while centralizing management.
