DVR is a digital video recorder. Compared with the traditional analog video recorder, it uses hard disk video recording, so it is often called a hard disk recorder. It is a computer system for image storage processing, with long-term recording, recording, remote monitoring and control of images/voices. This article focuses on the development status and future development trends of the DVR market.
DVR market development status
Along with the expansion of the DVR market, the number of newcomers in the market is increasing, which makes the DVR market extremely competitive and the product homogenization is serious. Now with the advent of high-definition smart cameras, traditional DVR products are facing a new challenge. Many people think that IPC+NVR will immediately replace DVR. Although this kind of worry is not unreasonable, the application of IPC is a peaceful evolution. It takes a long process. Although IPC may grow and even be faster than DVR, the number of channels in IPC will exceed the DVR for a long time, and the replacement of DVR will take a longer path. Therefore, DVR will continue to develop in a certain period of time, but the competition will be more intense. Enterprises need to work hard to make traditional DVRs better, such as better picture quality, lower cost, stronger network function and better stability. In addition, based on this, do some other product forms, such as hybrid, high-definition, etc., otherwise DVR may face a passive situation in the market knockout.
Intelligent technology integrated into DVR
Intelligent technology enables the "eye" function of the video surveillance system to have a certain "brain" thinking and judgment ability, so that the identification and processing of the personnel who need to be on duty should be handed over to the computer, thereby greatly reducing the workload of the on-duty personnel and improving the security monitoring. quality. Through automatic intelligent analysis of camera video images, the target automatic lock tracking, automatic warning, automatic alarm, automatic recording and other functions are realized.
In the future development direction of embedded DVR, intelligentization will occupy a very important position, and the development focus of technology has turned to video processing and video analysis. In the professional large-scale network monitoring system, such as Safe City, the number of monitoring points is huge, and thousands of them are moving, which brings unprecedented pressure for the processing, storage and network bandwidth of massive information.
The current embedded DVR has simple motion detection and alarm functions, but it does not have the ability of target recognition, behavior understanding, event recognition, etc., but the real security precautions require people to observe and analyze images in real time, thus obtaining The security evaluation of the scene, so the current embedded DVR belongs to the category of non-intelligent video surveillance systems.
In order to improve the intelligence of the monitoring system, people are freed from boring on-site monitoring. Many scholars combine optoelectronic digital image processing and analysis, pattern recognition, computer vision, artificial intelligence and other technologies with video surveillance to propose intelligent visual surveillance research. Direction, in-depth research in the field of detection, tracking, classification, recognition, target behavior understanding and event recognition of moving targets.
Intelligent technology with intrusion detection, cross-line detection, remnant detection, personnel flow statistics, traffic statistics, target tracking, etc. can effectively alleviate system pressure. The information originally processed by the monitoring personnel can be completed by the machine, thus reducing manpower. Workload and reduced human error. Through the video analysis of the machine, automatic tracking, automatic alarm and automatic recording are realized to improve the monitoring quality. The intelligent technology solves the storage problem on the one hand, and provides strong support for the historical information retrieval on the other hand.
DVR technology development trend
From a technical point of view, DVR has a long-term development, with image/voice recording, recording, remote monitoring and cloud mirror control functions, and integrates screen splitting, alarm control linkage, network transmission and other functions. At present, DVR technology has basically matured and its functions are basically perfect. In the future, DVR technology development direction believes that there are five aspects:
1. The hardware aspect can be summarized as faster processing and longer storage time. With the development of chip technology, higher performance CPUs make DVRs faster and more powerful. From the early CIF hard disk recorders to the current D1 hard disk recorders, 960H hard disk recorders, hybrid hard disk recorders, HD-SDI hard disk recorders. In addition, with the trend of high definition, the demand for storage is also increasing, and the DVR hard disk management technology is also improving. Basically, DVRs may support more hard disk interfaces, support RAID technology, and support compatibility with storage technologies such as DAS, SAN, and NAS.
2, the encoding method is more advanced, currently the mainstream DVR on the market uses compression technology MPEG-4, H.264, M-JPEG. MPEG-4 and H.264 are the most common compression methods in China, and H.264 has become mainstream because of its more suitable network transmission requirements. In the future, in order to make the embedded DVR have wider applicability, the unification of various algorithms will be the trend of future development. However, this unification is not based on the standards of any enterprise in China, but requires a wide range of government functions and DVR industry chain. Extensive participation of various types of companies. For example, China's AVS compression algorithm with independent intellectual property rights, as well as H.265 compression algorithm, has revolutionized many aspects compared to H.264.
3. The interconnection and interoperability function is more simple. Compared with the IPC, the ONVIF protocol is proposed. The DVR is upgraded slowly in the software version, and it is not open enough for integration and consistency. In terms of interconnection between products and the openness between systems, each company does not have a unified standard for products. The current system access is mainly through the SDK, and each vendor is in a separate position. It can only solve the interconnection and interconnection at a certain level. It is a long-term process to realize the interconnection and interconnection.
4. Intelligent. From a technical point of view, intelligence is an important development direction. Only through intelligent analysis technology can video information management be able to free people's work from complicated affairs. In fact, real-time monitoring, early warning, information processing, retrieval and other functions require intelligent technology applications. Although it is difficult to fully realize the management of intelligent analysis technology in a short time, the current technology can achieve semi-automatic monitoring intelligence to some extent, and in most cases, most of the work can be done by using intelligent analysis technology. Being able to focus on management and coordination processing is a good application at this stage.
5. The application of cloud computing is mainly reflected in cloud storage and cloud monitoring. For the security field, cloud storage is one of the main application directions in the field of cloud technology. Cloud storage refers to the integration of different types of storage devices in the network through application software through cluster application, network technology or distributed file system function to achieve a common working system for providing storage and access to the outside world. DVR cloud storage technology will also be supported due to confidential security and remote monitoring requirements. Cloud monitoring, using cloud communication technology, the video stream is directly transmitted from the camera to the monitoring terminal, without server relay, the picture quality is clearer and smoother; the platform is more stable and safer, 100% clearance rate, communication is strong and stable, the user terminal is real Plug and play, no need to install settings, no DDNS settings, no port conversion, real zero configuration, fully intelligent, adaptive to any complex network environment, automatic recovery of broken network video; support mobile phones, tablets, notebooks Computers, etc., various terminals access control through browser or client mode.
In summary, with the development of network technology, identification technology, microelectronics technology, codec technology, operating system technology, etc., the embedded DVR will be intelligent, integrated, wireless, high-definition, personalized, and interactive. The direction of development.
