I. Overview
This article refers to the address: http://
With the development of the national economy and the continuous development of banking business, the business volume of financial institutions has grown rapidly, but at the same time business disputes have increased, and bank robberies have occurred from time to time. Therefore, new requirements have been placed on the security of the financial system. There is an urgent need for practical, efficient, stable, and economical security equipment to conduct effective security management for every aspect of financial institutions. At present, the vast majority of financial systems use analog video surveillance systems for monitoring. This traditional analog video system cannot store large amounts of image information due to the constraints of the system itself, and cannot provide efficient and accurate retrieval and control. Long-distance connection and communication between local and metropolitan areas. Its basic functions can only achieve monitoring, recording, and alarm functions, and the cost is expensive, and the expansion functions of key components are very limited. Conventional video tape recorders are not ideal for processing sensitive images when the playback image is enlarged. It is difficult to find the problem, and the scope of use is greatly reduced. Functions such as image retrieval and network transmission are basically not realized. At present, the video surveillance system has gradually evolved into digital, intelligent and networked and has derived many new functions and requirements. It has become the first choice for many monitoring users.
Second, user requirements
1. Each channel has a long time digital video;
2. Real-time monitoring of each image site (sub-branch);
3. Each image remote (branch) real-time monitoring: without adding any network resources, sharing existing network resources, remote monitoring of any one of the images of each branch in real time at the branch;
4. Video data query multi-faceted: You can check the video data at the branch office, or you can remotely query the video data of the branch at the branch and download the required image data;
5. Various alarm signals are automatically linked;
6. Remote uploading of various alarm signals: Branch branch monitoring room where various alarm signals can be uploaded in time.
Third, the system constitutes
1. Part of a branch or savings office
On-site cameras with fixed lens or pan/tilt controllable cameras can be installed, and outdoor rain-proof pan/tilt + lens cover + decoder control is used. With electronic map alarm arming, each alarm point position and alarm response action can be set in sections. In the event of an alarm, the alarm detector and video control are linked.
Multiple cameras can be installed at each site, and the monitoring center can remotely select one camera image or optionally multiple camera images to form a monitoring image.
Image motion detection can be performed on the unmanned area of ​​the equipment room. When the image of the equipment room changes, the monitoring center prompts the alarm.
The human body infrared probe detector can be placed at the ATM teller machine. When the human body approaches the ATM machine, the system starts recording, and the human body stops recording when leaving the ATM machine.
2. Transmission network and backend part
The control center is connected to multiple remote branches through a router, and any host on the central LAN can simultaneously monitor multiple different branches. Relevant departments such as the president's office, the security room is equipped with a sub-control computer, and the sub-control computer can monitor any number of live video images at a certain time and can control them. The advanced Server/Clients system is used to transmit compressed images using TCP/IP. Therefore, whether it is an image remote transmitter or an image remote receiver, only the IP address can be defined, and any network can be configured.
The following figure is a simple topology diagram of remote monitoring in the solution:
Fourth, system function
1. Digital video
The recording time period is 1-3 months. Video data is automatically managed without manual intervention. After the hard disk is full, the oldest video data is automatically deleted, and the hard disk space is repeatedly used.
There are several ways to record videos:
• Manual control: manual operation of video;
• Automatic programming: automatic recording according to a pre-arranged schedule;
• Motion detection: recording starts when there is a moving object, and stops when the moving object leaves;
• Alarm linkage: Start recording when there is a sensor alarm.
2. On-site monitoring
The multi-channel image is monitored in real time on the computer screen of the branch.
3. Video data query playback
According to the corresponding time, place and lens number, each image can be retrieved, and the multi-faceted video data can be queried:
• Query playback on the computer at the branch site;
• Query playback through the LAN in the control center;
• Query playback via remote network on a remote computer in the branch monitoring room, the president's office or the security department's room.
4. Alarm processing
•Alarm
Sensor alarm signal connected to the video server;
Image motion detection alarm signal;
Video loss signal;
• Automatic processing
Alarm signal uploading branch;
The alarm signal is automatically recorded;
Linking the corresponding camera image recording;
Link the corresponding control device.
5. PTZ lens control
• Control the pan/tilt and lens at the branch site;
• The branch president remotely controls the pan/tilt and lens of the subordinate branch through the LAN
