HD monitoring problems and solutions

In recent years, the construction and application of high-definition surveillance systems has become a trend. Video surveillance has evolved from the "visible" standard-definition video security system to "visible" high-definition video surveillance systems. In 2011, as the outbreak year of high-definition products in the surveillance field, more and more manufacturers have joined this field and launched a series of high-definition video surveillance products. The front-end lens manufacturers and chip makers are also adopting high-definition video solutions. In the market, high-definition solutions have gradually become popular in areas such as transportation and bayonet, and the market share of high-definition surveillance in the traditional surveillance areas is also gradually increasing. According to a report released by the international authoritative electronics industry research organization IMSRESEARCH, the next five years, high-definition monitoring The market share of products will exceed the traditional standard definition monitoring products.

HD monitoring problems

HD network cameras have made a qualitative leap in image clarity, but they have also brought a series of real problems to high-definition surveillance systems. The three core issues to be solved by HD monitoring are: bandwidth issues, display problems, and storage problems.

Bandwidth problem: Due to the current limited network bandwidth, the high bit rate brought by high-definition video has become its biggest promotion bottleneck. How to transmit as high quality video as possible with the lowest possible bit rate is the top issue that HD surveillance needs to solve. At the same time, due to the heterogeneity of the network, different networks have different channel characteristics. Different users enjoy different network bandwidths. Even the bandwidth of the same user may change at any time. With the development of the monitoring field, various user terminals have the need to connect to monitoring video. For example, the network bandwidth of the local area network monitoring network is ideal. Users want to browse high-quality video. In the field of mobile phone monitoring, because the bandwidth is limited, users value the low code. Rate video fluency. How to adapt to these different bandwidth environments is also a problem that HD surveillance devices need to solve.

Display problem: Compared with standard definition video, the amount of high-definition video information is abundant, and the corresponding requirements for decoding display performance are also greatly improved. For example, the current mainstream PC can easily achieve 8-channel D1 standard definition video decoding display, but if the front end is 1080P high-definition video, can only barely decode and display 1 way. For large-scale video surveillance platforms, if all use high-definition video, server decoding pressure will be great.

Storage issues: The increase in image resolution will inevitably consume more storage space. Taking 1920×1080@30 frames of video as an example, using the H264 encoding algorithm, to ensure clarity, the code stream needs to be maintained at more than 6Mbps, which is about 4-8 times of standard definition video. Under standard definition video conditions, a 16-channel DVR built-in 8 fast 2T hard disk can meet the long-term video storage requirements. In high-definition monitoring, this time will be greatly shortened, which will bring about increased storage غير مجاز مي باشدts.

Application of Video Coding Technology in High-definition Monitoring System

The development of video coding technology has brought a new method to solve the above-mentioned high-definition monitoring problems. Through the improvement of the encoding method, the applicability of high-definition video can be greatly improved, enabling it to adapt to more monitoring scenarios.

An enterprise in the industry has been committed to the research, development and promotion of high-definition video surveillance equipment. It has achieved a number of technological breakthroughs in the core algorithms of video compression. Currently, there are areas of interest that include compression coding technology, scalable coding technology, and intelligence. "Front-end" dynamic coding adaptive technology.

Region of Interest Compression Coding (ROI): Video compression ratio and video quality are contradictory bodies. The higher the compression ratio, the more video loss, and the worse the corresponding video quality. However, when watching video surveillance, people usually only interested in a specific area (usually the central area of ​​the video). The images in this area should be as clear as possible, and other parts of the image may be relatively blurred. Based on the above requirements, a compression coding technique for an image region of interest arises, that is, lossless compression or lossless compression of a region of interest in an image, and lossy compression of a background region. This can not only make the reconstructed image have higher video quality, but also get a higher compression ratio, which solves the contradiction between compression ratio and image quality.

Picture 1 is the original image; Picture 2 is compressed and generated by an ordinary video encoding algorithm without ROI processing. Obviously, the entire picture has become blurred due to the loss caused by video compression; the face image that is more interested in monitoring has been performed. ROI processing, coding to get picture 3. It can be seen that the sharpness of the background area is similar to that of the picture 2, but since the face is subjected to ROI processing, more details are saved and visually clearer than the picture 2. In high-definition equipment, compression is performed using a high compression ratio, and the central area of ​​interest for monitoring is processed using ROI technology to obtain lower bit rate, high-vision-quality video.

Scalable video coding technology: It is achieved by dividing a single stream into several layers. If the codestream generated by the video encoder after one-time compression can be decoded by the decoder at different code rates, frame rates, spatial resolutions, and video quality, the codec system is said to have "scalability". From this definition, we can see that scalable encoding only needs to encode the video program source once, and then it can reconstruct the video with various resolutions, bit rates, or quality levels by transmitting, extracting, and decoding the corresponding part of the compressed code stream. Compared with the currently used simulcast encoding method, this encoding method has a stronger ability to satisfy various different needs and greatly improves the encoding efficiency.

The single code stream provided by the encoder has a scalable feature and can automatically adapt to the user network's network status and terminal equipment. In a network with a good bandwidth, high-resolution and high-quality video can be transmitted, and in a low-bandwidth environment such as mobile phone monitoring, only low-resolution and low-stream video can be transmitted.

The basic idea of ​​scalable video coding is described as follows: The encoder encodes the video sequence into a base layer and multiple enhancement layers, as shown in FIG. The base layer has the lowest video quality, and the enhancement layer can improve the quality of the base layer. High-definition monitoring equipment can select the amount of data to send based on bandwidth and terminal requirements.

For example, in a space scalable encoding application, the resolution of the mobile video is small. In this case, there is no need to transmit more enhancement layers (corresponding to a higher spatial resolution), and only the basic layer suitable for the resolution of the mobile phone can be transmitted. . The receiving end decodes the corresponding quality video according to the received data.

The more enhancement layers received, the better the decoded video quality. It is usually assumed that the base layer data is lower than the minimum transmission bandwidth, so the decoder can always decode the lowest quality video. By using a high-definition video encoder that uses scalable video coding technology, it can adapt to the video monitoring requirements under various network bandwidth conditions, and the bandwidth problem is no longer a problem. At the same time, the decoding end can also choose to solve only the basic layer according to its own decoding capability. The video still decodes more enhanced video, which greatly eases the problem of insufficient display capability when displaying high-definition video.

"Smart front end" dynamic coding adaptive technology: Through the application of "region of interest coding technology" and "scalable video coding technology", the pressure on network bandwidth and decoding display capability in high-definition surveillance video is greatly reduced, but it takes up much storage space. The problem has not been solved in nature. The development of intelligent video analytics technology has brought new ways to solve this problem.

Most of the videos in the surveillance industry are redundant. Users are more concerned with the specific video when abnormal events occur. The "smart front-end" high-definition network cameras, combined with intelligent analysis algorithms, can achieve cross-border, mixed lines, and regional stays. Remaining behavior analysis. In the normal state, "insignificant" video streams are recorded in SD format. Once an abnormal state occurs, the video is automatically switched to HD video, which ensures the details of the surveillance video without causing excessive pressure on the storage. Improve the efficiency of effective video retrieval. Verified, can save 30% -50% of storage space.

Conclusion

The progress of video coding technology has brought new developments to high-definition surveillance, effectively alleviating the bottlenecks that high-definition video surveillance has encountered in terms of network bandwidth, decoding and display capabilities, and storage resources, becoming the most powerful boost for the overall high-definition monitoring industry. power. Some security companies are positioning themselves as technology-leading enterprises, adhering to the development direction of high-definition and intelligentization, giving full play to their core technology advantages in video coding, and continuously blazing new trails, serving the society, and serving users, helping the security industry to achieve full HD development of.

The importance of key technologies for bank network monitoring

Banks belong to the country's key security and prevention units, and are characterized by various scales, numerous important facilities, complicated access personnel, and wide management areas. As the main circulation place of the current social currency, it plays an important role in the economic operation of the country. It serves a wide range of domestic industries with its unique features and advanced technologies. As banking business involves a large amount of cash, securities, and valuables, it has been the focus of various criminals; since the birth of modern banks, theft and anti-theft, robbery and anti-robbery, fraud and anti-fraud, etc. The development of the development is also synchronized. At present, criminal activities against banks are increasing. The criminal means and methods of crime have also gradually diversified, and the security and prevention systems of modern banks have been comprehensively strengthened and renewed; in order to adapt to the operation of the banking system and business development, it has become imminent.

I. The composition of bank security networking system
The construction of banking security networking system should be based on the bank's business characteristics and security requirements, with the bank security integrated management platform as the core, digital, high-definition, and networked product technologies to achieve multi-level network monitoring of outlets, branches, and head offices. Integrate high-definition video surveillance systems, GIS systems, alarm systems, access control systems, and intercom systems into one, and through the combination of security systems and banking systems, build a regulatory information platform that meets the needs of modern bank security management.

The overall structure of the bank security networking system shall adopt the special network structure of the provincial branch's primary monitoring center, the municipal branch's secondary monitoring center, and the district-county branch three-level monitoring center. The first-level monitoring center requires the establishment of branches at each provincial level. The monitoring center requires the establishment of branches in various cities. The three-level monitoring center requires the establishment of branches and sub-county branches; in order to ensure the security and reliability of the networked system, the above three-level networking architecture must be established in the bank's special network system, such as the lease of China Netcom and telecommunications. , mobile and other circuits establish a financial information security special network.

Currently, the bank security networking system is based on the bank's inline private network VPN. It is required to comply with the Intranet technical system and the status quo. It cannot generate excessive information traffic to the Intranet, and it cannot form the factors that cause the network to crash. It also needs to implement security supervision. The accuracy, timeliness and reliability of information. The bank's in-line special network is divided into three layers, including monitoring of business outlets, monitoring centers of various cities, and monitoring centers of provincial branches. The office network of the regional monitoring center to the business outlets of the jurisdiction is generally 2 Mbits bandwidth. To achieve high-definition monitoring, it is necessary to transition to 4M bandwidth. Considering the other غير مجاز مي باشدts of network protocols and service data, the bandwidth that can be allocated to the actual monitoring network is about 50-75%. (ie, 2 to 3 Mbits). Therefore, each business network point can transmit one HD 1080p video or two video video streams to the upper level monitoring center. When the bandwidth is too low, the low bitstream network transmission can be selected to ensure smooth video surveillance and reduce the actual bandwidth. .

1. Bank network special network platform composition and function
The bank network system uses a private network as the basic network platform to realize the interconnection, intercommunication, and control of various security subsystems based on different network platforms within the banking system. It mainly has the following basic functions:

2. The composition and function of the primary monitoring center system

The first-level monitoring center system is usually composed of a central management server, an alarm server, an HD decoder, a monitoring video wall, and a centralized storage server, and has the following basic functions:

(1) It can manage video surveillance sites and secondary monitoring centers in this jurisdiction.

(2) It can receive and process the alarm information actively uploaded by the secondary monitoring center.

(3) Centralized storage of important surveillance videos in the areas under its jurisdiction.

(4) The front-end equipment can be controlled.

(5) Support rapid electronic map navigation and realize the management of all subordinate monitoring points through electronic maps.

3. Secondary monitoring center system composition and function

The secondary monitoring center system is usually composed of management servers, high-definition decoders, monitoring video walls and other equipment, and has the following basic functions:

(1) The front-end device can be controlled.

(2) It can realize the recording, playback and upload of remote images.

(3) Support for alarm linkage access and processing, can receive monitoring equipment alarm events within its jurisdiction; and record and process video.

(4) The forwarding and distribution of various video image requirements at business outlets can be realized.

(5) For the monitoring equipment at the front-end business outlets, not only can the basic data information be obtained, but also the equipment operating status can be detected through the inspection function.

4. Composition and function of business network monitoring system

The monitoring system of business outlets in various places is usually composed of high-definition cameras, alarm probes, hard disk recorders, or NVRs, ATMs, access control bays, etc. The main functions are as follows:

(1) The business network monitoring system shall have the capability of supporting various image formats such as CIF, D1 (4CIF), VGA, 720P, and 1080P. The collected data can be uploaded and saved in real time, and video data can also be synchronously forwarded.

(2) The monitoring center has control commands for controlling the pan-tilt, lens, etc. It can collect alarm information and upload related information to the superior monitoring center through the network.

(3) General video recordings should be kept for more than 30 days in monitoring storage devices, and monitoring videos for important parts should be kept for more than 60 days. Video for emergencies or major cases is transmitted to the upper monitoring center server for backup and preservation.

Second, the key technologies of bank security networking system

The bank security networking system requires an open architecture, standardized interfaces and protocols, good compatibility and scalability, compliance with national and industry standards and regulations, and full use of existing alarm systems, video surveillance systems, and transmission resources. Realize system integration, resource integration and information sharing.

(1) The equipment involved in the bank security networking system must meet the requirements of reliability and safety. The selection of equipment cannot be selected as a test product. It is necessary to select advanced mainstream products on the market and ensure that the system equipment operates without interruption.

(2) Critical data devices and interfaces should be designed with redundancy. They must have the functions of fault detection, system recovery, etc. The information transmission and data storage under the network environment should be more secure to avoid being attacked by malicious attacks and illegal data extraction. appear.

(3) The banking security networking system requires a network system with resource sharing and rapid response. Therefore, it is necessary to strengthen the real-time supervision and management of the operating conditions of the network system, ensure the stable operation and rapid response of the system, and consider and operate based on the following points:

1 The system should adopt a unified user authority authentication management mode.

2 The system should adopt a multi-level user rights management mechanism to prevent users from exceeding their authority.

3 The server device should be able to limit or control the access of certain IP clients.

4 The system log operation function can record important events in the log list, and store the classified and scheduled backups to prevent data loss due to hardware failure.

(4) The bank security networking system should adopt multiple methods to ensure network security. First of all, external network isolation must ensure the absolute security of the networked system. The system networking should be strictly established on the bank intranet platform and be completely isolated from the external network to ensure that it cannot pass through any external network and public network system. The system performs connection access (VPN network can also be used). Secondly, intranet isolation requires that the provincial branch network subsystems and the local city branch network subsystems must be separated by a firewall. At the same time, the firewall needs to support non-pure software for address, protocol filtering, packet filtering, secure identity authentication, and remote management.

(5) The information security of the banking security network system mainly includes the authorization mechanism and the identity authentication mechanism. The authorization mechanism should adopt the role-based access control model in the networked system, support the authorization of users at different levels, and can realize the monitoring of the decentralization such as login, browse, read, modify, and delete. In addition, the identity authentication mechanism can implement the identity authentication of the user of the computer system, the identity authentication of the user to the computer system, and the identity authentication of the computer system to other computer systems.

Third, the application of bank security networking system

The banking security system network management is the focus of bank security construction in recent years. With the development of technology and demand, bank security has evolved from local management to networked management, and network management applications have evolved from the first off-site storage facilities to self-service banks, business establishments, etc. Fully networked applications. At present, banking security networking applications have fully covered all subsystems of banking security and have been extended to business outlets. Self-service banking, treasury and other departments provided strong technical support for bank operations management.

A solution for bank security networking systems. Among them, the business hall adopts high-definition video with ultra-wide dynamic image processing technology, which effectively avoids the problems of backlight imaging; at the same time, it also implements the supervision of teller business personnel, such as the movement of the cash box, cash registers, and other operations. In the self-service banking area, a wide dynamic function pinhole camera is used to identify and monitor the face of the payer, and the collected information is transmitted to the superior monitoring center in real time. In case of abnormal idle conditions, the alarm can be promptly reported. In addition, the Treasury uses a variety of equipment technologies such as access control, alarms, and monitoring. It can carry out multiple identification and certification of entry and exit personnel and has a strict authority management mechanism. Different levels of personnel can be authorized differently to prevent illegal intrusion.

Intelligent Video Analysis Technology Port Application

The video surveillance system of the existing ports in China is mainly composed of cameras, optical cables, matrixes, hard disk recorders, and video walls. Due to the large number of video surveillance images and boring contents, the existing systems, even with on-duty personnel, are still in an unattended state in most cases.

When a crime incident occurs, the retrieval of video playback and forensics from the DVR becomes one of the major values ​​of the system. Even if on-duty personnel are on duty, due to the physiological characteristics of human beings, it is impossible to effectively observe multi-channel images for a long time, which may result in the omission of suspicious events and misjudgment of safety forms.

Intelligent video surveillance technology can be understood as using a computer to help watch people watch video surveillance. The high reliability of modern computers can provide 24-hour protection. Fundamentally eliminate the omissions caused by fatigue. At the same time, it is also possible to prevent the possibility of colluding inside and outside the monitoring staff.

The existing intelligent video analysis technology cannot replace people. It still needs people to recognize the nature of the alarm and decide the disposal method. Its value lies in greatly reducing the intensity of the monitoring personnel's work and making the quality of monitoring a qualitative improvement. Compared with traditional video surveillance systems, intelligent video analytics can detect or even prevent crimes from occurring. The significance of this sensitive and critical infrastructure such as the port is obvious.

The function of intelligent video analysis technology and its application in ports

The demand for video surveillance systems in domestic ports is mainly due to the need for theft prevention, production safety, and anti-terrorism. The valuable materials in the port and the surveillance of key departments are typical application scenarios.

Since China signed the Sonus Convention, all ports exported to the United States must meet certain security standards. At the same time, as an important part of the national economy, the port’s anti-terrorism has also been incorporated into the agenda by major domestic ports.

The main function

Currently, intelligent video analysis systems on the market generally have the following functions:

1, image acquisition / interface. The vast majority of intelligent video analysis algorithms are based on non-compressed image formats such as RGB or YUV, so image signals are sent directly to the video analysis unit without being compressed after being captured. Almost all video analysis systems are equipped with an image capture function, usually through the BNC input analog image signal. The image signal in the existing image monitoring system usually exists in the form of a compressed image stream, and the image stream can be decompressed and restored to the original image format before analysis.

2, moving object detection. In simple terms, motion detection is the discovery of moving objects in an image. Moving objects can simply be defined as changing parts of an image. Some elementary motion detection algorithms are based on these concepts. The false alarm rate of such methods is too high to be suitable for real-time alarm systems.

Not all changes in the image are moving objects that we are interested in. For example, changes introduced by the camera itself include pixel noise, overall brightness changes caused by the camera's auto iris control circuit, and high- and low-frequency periodic noise signals introduced in image transmission. , mutations caused by infrared camera cycle calibration. Changes introduced by the external environment include rapid changes in the ground light in cloudy weather, shadows of moving objects, waves or sparkling phenomena on the water surface, swinging of branches on land, halo caused by headlights at night, and rain and snow weather.

In addition, the camera shakes easily on windy days, especially high light poles. The image changes caused by these phenomena should be filtered out. They can be solved by algorithms or other technical means.

Home Previous Next Last From the point of view of the algorithm, it can be simply divided into two categories. One is to establish a background model and find the moving object by comparing it with the background model. The other type is to find moving objects through the optical flow method by finding the effect of moving objects on the optical flow field. The other is a method that combines the two or a combination of the two.

3, multi-object tracking. Tracing is essentially stringing together the same objects found on each frame in chronological order. This area itself is a relatively independent and active research area. The main research direction is to effectively track under complex circumstances such as multiple moving objects, multiple cameras, moving objects blocking each other, disappearing and recurring.

In practical monitoring applications, especially for some intrusion alarm application cases, the requirements for tracking algorithms are relatively low. The existing system does not have satisfactory tracking effects on moving objects and other complex application scenes. However, with reference to the pace of technological development in the past, this aspect will soon be perfected.

4, behavioral characteristics analysis. The behavioral feature analysis is to look for an event that meets a predetermined behavioral characteristic from the image. Typical applications on the market today include:

(1) Classification. Judging that the moving objects are people, cars, boats, airplanes. Stop or abruptly accelerate, such as when a vehicle is anchored in a tunnel or on a highway, a scene of a robbery on the street, and a chance to escape.

(2) Hey. Persons who are observed outside the sensitive area. Pedestrians and vehicles that pass normally are not alerted.

(3) Leftovers. Place explosives at airports, oil depots, etc. and leave.

(4) The item is missing. If the museum’s valuable exhibits discover the disappearance of exhibits, the system will immediately call the police.

(5) Statistics of the number of people. For example, statistics are made on the number of people entering supermarkets and other places, and the average consumption curve of one day is plotted against sales data.

(6) Population density. Such as when the alarm when the number of personnel is too large, or when the crowd suddenly spread out anomalies occur when the alarm.

(7) The staff fell to the ground. For example, when the staff suddenly changes from straight to flat.

In general, intelligent video analytics can do a lot of things and require video analytics developers and end users to communicate effectively. As intelligent video analysis is still a relatively new technology, the circle that knows this technology in the country currently only expands to the integrator level. Many application scenarios suitable for video analysis technology have yet to be developed in the market. However, one thing is clear: companies must master core technologies and have independent research and development capabilities. The intelligent video analysis market is composed of many subdivided small markets, and new applications are constantly emerging.

5, set the alarm conditions. The introduction of intelligence in video surveillance has greatly enriched the monitoring content. Currently available alarm elements include areas, time periods, object types, dimensions, direction of movement, speed, behavioral characteristics, and many other things.

6, alarm linkage. After the abnormal situation is found in the intelligent video analysis system, it is usually necessary to verify the authenticity of the alarm, such as detailed investigation of the close of the alarm event by another PTZ camera, or promptly notify and remind the monitoring personnel. Common real-time prompt methods include voice, pop-up images, sending text mesغير مجاز مي باشدes, screenshots and other means to prompt monitoring personnel.

Special function intelligent video analysis can also solve the special needs of the port

Especially in the area of ​​safety production. For example, in the illegal parking of container yard roads, the container trucks are not allowed to park under the bridge cranes, and the coal yard is burning spontaneously. Since intelligent video analytics technology itself can be applied to many fields, communication between ports and video analytics companies can bring many new problems to the port.

Special problems encountered

Compared with other smart video analysis application scenarios (eg, prisons, power plants, banks, vital organs, etc.), the port project has the following difficulties that require attention:

1, a large range

The perimeter of the port is usually a few kilometers or more. It is usually relatively empty. The available installation points do not necessarily meet the requirements of a typical intelligent video analysis system. This is mainly due to the fact that the typical detection distance of existing products is usually in the range of tens of meters, and individual manufacturers can do farther. Technically, it is mainly the conflict between resolution and processing power. If the resolution is too high, some low-end systems cannot process such a large amount of image data in real-time due to the increase in the amount of data. For the port, analysis using D1 (704 times 576) images is often encountered.

2, camera shake

Since the port is usually open and faces the sea or river, camera shake is certain. Even if the camera is fixed on a very thick lamp pole, shaking cannot be avoided on a windy day. For a fixed camera using the background model method, camera shake must be effectively compensated before it can be used, otherwise a large number of false alarms will be generated.

3, surface waves, reflective

The above technical difficulties are solved in some existing commercial systems. Therefore, when selecting the system, you must identify it.

When monitoring the waters of a dock, such as intrusion of a small raft, if it does not properly handle the sparkling phenomenon caused by water wave and sun reflection, it will cause a large number of false alarms.

Technology development trend

Intelligent video analytics is at an early stage both in terms of technology and market maturity. Some new products and new features continue to emerge. In general, foreign countries have a wider range of applications than the domestic market; there are fewer domestic independent R&D manufacturers and more manufacturers integrate foreign systems. In the long run, the development of video surveillance systems in the direction of intelligence is increasingly being recognized by government agencies, integrators, and end users. How to choose the time to enter the market, and to use intelligent video analysis technology to improve the port security level, and then to improve the owner satisfaction and find a mature technology to achieve a balance between the port security department needs to consider their own situation.
