One, system overview
Banks have long been the focus of the security area, also belong to national key units to be safety. As the main circulation of currency in today's society, an important part of the national economic operation, it by its unique function and advanced technology service in all walks of life at home. But because of its wealth, the characteristics of the liquid, also make it easy to become extreme criminals malicious violation goal, thus improve the scientific management of bank system and security ability is especially important. And the choice of monitoring and control system directly affects the degree of the financial system security, good or bad. Banks to some extent, the effective application of the existing monitoring system gives security ability improved, but also from the aspects of monitoring capacity and monitoring effectiveness basic stay on phase of traditional video monitoring mode, in most of the time can only be used after the forensics, cannot have the effect of prevention, early warning. And there must be a specialist in the observation, control and analysis the camera image, security personnel need to surveillance video images so much, far beyond people's ability to accept, leads to low actual monitoring results. The experimental results show that the staring at video images only 22 minutes later, the human will ignore more than 95% of the activity in the video image information. So we need intelligent video monitoring to improve the monitoring effect, reduce the burden of security guards at the same time.
Second, the basic technical specifications
Intelligent video surveillance utilizes advanced computer vision, artificial intelligence technology, such as perimeter of video monitoring and abnormal behavior analysis, extract the key information in the video image for the user. From intelligent analysis commonly used technology for, mainly include the following:
2.1, foreground object detection
At a fixed camera monitoring the area of concern, the extracted from video image texture, color and other information, to determine the monitoring area basic background model, and through the period of different attention to the change of the background model. Again according to the actual detection rules for judging the object specific behavior, the application of this technology will be able to effectively implement perimeter detection and recognition of the basic behavior. Such as trespassing, cross-border, items disappear, item's legacy, etc.
2.2, characteristic pattern analysis
The basic characteristics of the first extracted from video image, such as image color, texture, etc. And on the basis of these characteristics can draw the basic information of the test object, such as people, vehicles, characteristics of the basic information of the object, and through the tracking and pay close attention to changes in these characteristics determine the detection object behavior. The application of this technology can realize the object tracking and classification, etc.
2.3, the movement pattern analysis
It is within the video image object after the course form, according to the trajectory of the object's behavior, or properties do further analysis and confirmation. On the one hand, it can be combined with a foreground object detection, remove the leaves, cloud, such as the false alarm, enhance the adaptability of the scene; By detecting the object trajectory detection on the other hand, can effectively achieve the retrograde motion detection under the crowded scene, pedestrians abnormal acceleration, fighting, crowds gathered and so on.
HaoYun intelligent video analysis system based on the above, specifically for the characteristics of people and people movement pattern analysis, collection and describes all parts of the body silhouette, relative position, color and other characteristics, formed a huge amounts of auxiliary classification information, with the result of the movement tracking to the nature of the human behavior, or in the video, can achieve such as into the box, retrograde, stranded, tailgate, fighting, and organizing a mob to abnormal behavior detection.
Three, general basic module, intelligent video
Intelligent video is a high-end application of the video monitoring, it with its powerful functions have a great supplement the traditional monitoring and enhanced. Intelligent video analysis system can meet the demand of industry diversification, and function modular design is adopted to provide perfect solutions for different industry. The main function module can be realized as follows:
Perimeter detection
Automatically detect intrusion monitoring protection zones of the intruder (people, objects, or transportation), can automatically distinguish intruders characteristics such as type, size, speed, direction, and report to the police. In particular it can implement the following six basic detection behavior.
(1) into the restricted area: to test whether anyone, objects or vehicles to enter reservation area, flexible user can adjust the sensitivity;
(2) leave the box: to test whether anyone, objects or vehicles leave the reservation area, flexible user can adjust the sensitivity;
(3) one-way cross-border: to test whether anyone, objects, or a vehicle from a specified direction to the border with reservation, single direction detection, also known as the "one-way trip wires";
(4) two-way cross-border: to test whether anyone, objects, or a vehicle from any direction to the border with reservation, the two sides to test, also known as "two-way trip wires";
(5) the sluggish leave: to test whether someone approaches, objects, or vehicle for a long time to stay in the specified area, when the retention time than the preset value, the system will give alarm.
(6) : to test whether someone approaches, objects, or the vehicle is pacing back and forth in the designated area for a long time, when hovering over the preset value, the system will send out alarm;
Retrograde motion detection
In densely populated areas to provide way backward movement of people, objects, or vehicle for testing. Some typical application scenario is one-way flow gateway or area.
Abnormal running
Detect whether there is a fast moving, can distinguish between pedestrians, vehicles, or objects in theft or robbery behavior.
A fight
That can detect whether there is a fight, fight can distinguish between pedestrians, objects or vehicles.
group
Detect whether there is a group gathered phenomenon: based on the regional groups (sometimes) for vehicle intensive qualitative detection, to obtain a crowded estimate, from on macroscopic to automatically detect congestion behavior and report to the police.
Legacy object detection
Vehicles or dock of unknown origin items or place in the region of the set alarm occurs in more than a certain amount of time. Such as someone left the parcel or explosives. Mainly used to detect suspicious objects abandoned in a public place, is the typical application of counter-terrorism.
The sudden
When a great change of the video image alarm system. Such as camera obscured and greatly moves, effectively prevent criminals through block and turn the camera to destroy criminal evidence.
Entrance guard followed monitoring
Detect whether someone followed by access control and other special channel, effectively prevent the following behavior theft and robbery.
The number statistics
The entrances of statistics in and out of the population, based on the gateway in the number of real-time information, can get real time within the closed space ownership, statistical results can provide the number of period of time. And in the total number of more than the preset value, the alarm system.
Video quality monitoring
Video of the leakage of video image, snow, scrolling, fuzzy, partial color, screen freezes, gain imbalances and yuntai camera out of control and other common fault judgement and send out alarm information. To protect important cameras in a timely manner and the interests of the bank, which can effectively prevent illegal points against various for ATM crime becomes an increasingly urgent problem. For now, the bank ATM system basically has been put on the video monitor equipment, there is no doubt that to a certain extent, cause of crime in criminal threats, but in the real sense, but still only stay on for later forensics state. Difficult to really effective help to deal with emergencies. It is imperative to promote the application of intelligent video surveillance is a bank of one job.
ATM access gangway
24 hours monitoring ATM gateway personnel in and out of the situation, in the real-time video at the same time, to prevent the occurrence of abnormal behavior.
Queue waiting area
Real-time monitoring for queues personnel and closely monitor queuing one-meter line.
Automated teller machines (atms) around
Real-time monitoring ATM nearby personnel flows, real-time information record personnel flow, eliminate unsafe factors.
ATM area
Sensitive areas belong to the bank, generally in a state of no duty, high level of security control requirements. Need to guarantee different people life and property of absolute security.
Implementation plan
Automated teller machines (atms) is the key area of bank security, because of the unattended while operated 24 hours day and night, making it for video monitoring rely on determines the magnitude of safety factor.
On the ATM crime commonly used means of it, basically can be divided into interference three camera, destruction, camera, keep out cameras.
Criminals in the ATM crime often know, ATM is equipped with a camera and can record the entire process, crime to evade capture, is likely to use their camera image by means of radio interference interference, increase the difficulty of evidence collection, analysis, and discriminant after the incident. For this kind of situation, HaoYun intelligent video analysis system of "change" function can be achieved when a great change of the video image automatic alarm system. Such a system can be quickly at the first time to inform security personnel processing, effectively prevent criminals through block and turn the camera to destroy criminal evidence.
ATM access to access point can access following monitoring function, detecting whether anyone followed by entrance guard, or a single credit card, people through the door. Discovery immediately remind attention, effectively prevent the following behavior theft and robbery.
Queue waiting area, through the perimeter detection function, defined in one-meter line rules, a but someone suddenly from behind the team more than one-meter line distance line, the system will automatically warning. Behind this will effectively prevent peeping steal passwords.
Atms around, wandering and retention tests personnel flows around the ATM, but someone stay near or hover time exceeds the preset time value, the system automatically forward security alarm. And the discovery of the incident, intelligent video analysis system for the further processing of dynamic image magnification, so more conducive to the recognition of suspicious objects and records.
ATM machine area, 24 hours to provide different services, no duty because of its characteristics, on the degree of dependent on video monitoring is very high. Through HaoYun intelligent video analysis system for all-weather kitsch area detection, when the phenomenon of regional scale appear left more than the preset value, the automatic alarm system. On the one hand, pay attention to package. At the same time will also be effective to eliminate the risk of malicious left phenomenon, is the typical application of anti-terrorism in this area. Second in the regional scale, through intelligent video analysis system for detecting all-weather fight, abnormal behavior of video monitoring analysis, and judgment. Can timely to curb illegal and criminal behavior of deteriorating even further.

Demand analysis
Security monitoring is the key of the bank security system, only to properly handle civil air defense and technology dimension is a reasonable relationship, enhance dimension is upgrading, strengthening vaults, keep the library room, office, office space, business hall each main areas such as monitoring ability, can better plan in the future, effective safeguard the normal order of business bank.
Vault area, business area, business departments electronic clearing room: a comprehensive monitoring personnel in the area of activity and anti-theft system for 24 hours real-time surveillance video at night, and in case of emergency for the first time will be alert to security departments to handle in time.
Such as: counting, handover between, between the control room monitor in the activity room, sensitive area belongs to the bank, not permission, irrelevant personnel shall be prohibited from entering.
Outside the door, office front door: all-round monitoring gate access, and the overall grasp on the surrounding environment.
Important passage doorway: closely monitored discrepancy condition of each channel personnel and security access.
Office space, business hall: the stream of people the most densely populated area, also the foreign bank service area, low safety factor. Need comprehensive monitor activity, and found the unsafe factors in time, to effectively manage at the same time, safeguard the normal order of business.
Implementation plan
Security monitoring is the basis of bank security system, the bank every year spend a lot of manpower and material resources and financial resources to ensure the normal order of business bank. And actually existing monitoring systems are based on the traditional view, the basic function such as storage, retrieval, playback application of monitoring system. Is the machine of eye and eye pattern, because of the limitations of human monitoring and control system
Monitoring capability is limited by a lot. Intelligent video monitoring system of the security personnel from the traditional monitoring at the same time, to the bank's security provides more likely.
Vaults of the library, library mun, business area, business departments between electronic clearing room, counting, monitoring room belongs to the sensitive areas of bank, non-bank staff are not allowed to enter, the intelligent video analysis system, define the detailed area perimeter detection and alarm, for illegal intruder monitored 24 hours a day, once found someone to enter this area immediately report to the police. This will in unattended situation, effectively such as theft, robbery, destruction of malignant events happened, vigorously protect the safety of the property.
All areas outside the door, and the office front door is stream of people is opposite bigger, more unstable factors, is the main type security monitoring several sites, have been supervised by intelligent video analysis system for key, perimeter around the gate and define events such as illegal detention, wandering, immediately report to the police found the suspect or object. As far as possible eliminate unsafe factors surrounding the Banks.
The door of the important channels, is one of the main areas of video monitoring, through the intelligent video surveillance system, define the crowd at the gate of the various intensity detection, when the channel number more than the preset value, the system automatically alarm, then staff can promptly take appropriate measures of reasonable arrangement, in order to prevent the number too much jam phenomenon of channels. At the same time, through the monitoring of important channel, the definition of events, the action of running, fighting, once found a video with abnormal running and fights, will immediately report to security personnel, reminding, effective monitoring criminals fled after the robbery, theft behavior, to achieve the first time the tracking process.
Office space and foreign business hall is of the highest densities of construction bank personnel area, the complexity of security determines its efforts in safety will be increased, in the business hall, through HaoYun intelligent video analysis system, realize the legacy object detection, when found an unidentified object in area for unattended for more than the preset value, the system will alarm immediately, alert security personnel related processing.
4.2.4, bank comprehensive diagnosis system of video quality
For video equipment is used in great quantities in the bank and need for effective management, can be diagnosed by video system for video image of snowflakes, scrolling, fuzzy, partial color, screen freezes, gain imbalances and yuntai camera out of control and other common fault make accurate judgment and to send out alarm information. Effective prevention of image quality problems caused by the hardware and the unnecessary loss, the timely detection of damage monitoring equipment of wrongdoing.
Combined with Banks in terms of the actual video quality diagnosis application, concrete can be divided into the following two kinds:
1. The inspection of the quality of video is given priority to with emergency
In view of the bank of some important areas, such as Treasury, AYM, control room, etc. Must ensure that the video surveillance camera of absolute security, guarantee the daily operation of monitoring equipment, within the scope of bank security control makes monitoring equipment functioning. Find someone malicious destruction or shade can give warning in time, to detect damage the wrongdoing of monitoring equipment, remind related personnel to take measures and timely treatment.
2. The inspection of the quality of video is given priority to with maintenance
In the face of all video surveillance cameras, due to the problems in use process, such as video resolution, video interference, video brightness anomaly, partial color video, video signal loss, screen freezes, etc.), effective prevention of image quality problems caused by the hardware and the unnecessary loss, for the continuous and effective monitoring of the video monitoring provides a solid foundation. When your equipment failure can the first time for repair or replacement.
