As the earliest application of video surveillance, the security market has developed extremely rapidly and has begun to take shape. In recent years, it has been developing rapidly at a growth rate of about 15% to 25% every year. "Harmonious society, safe city" not only puts forward new and higher requirements for security product technology and solutions, but also changes the concept of security monitoring application.
Security monitoring development and information storage
In three stages, we can clearly see the changes and development of storage technology for monitoring data. The CCTV (Closed Circuit Television) system, which was originally characterized by analog signals and equipment, uses VCR (VideoCassetteRecorders) to store monitoring data; to digital or partial digital monitoring systems, DVR (DigitalVideoRecorder) or NVR (NetworkDVR) ) Storage monitoring data; to the now booming networked video monitoring system (IP monitoring system), using newer storage technology (DAS, NAS, IPSAN or FCSAN, etc.) to store monitoring data. This is the three-step development path that the monitoring system has gone through and three different eras of monitoring data storage.
Objectively speaking, the current analog technology still occupies a large proportion, but its limitations are very obvious. The increasingly wide and deep application of digital and networked security technology has become an inevitable development trend. In the early stages of the security market for analog technology and digital technology, users paid more attention to hardware equipment, such as cameras, etc., so in the first and second generation monitoring systems, the storage concern and solution is how to faithfully monitor the monitored data. , Completely recorded, so that future accidents can be effectively queried, so the importance of monitoring data is very limited. It can be said that the focus is on the collection and transmission of monitoring data. With the development of networked monitoring, its data collection application is becoming more and more common, and its scope is getting wider and wider. Traditional data storage methods are increasingly unable to meet the demand, that is to say, it is difficult to meet even the most basic data for future review. From the user's perspective, the existing monitoring is basically an independent system. Various industries or different regions within an industry can obtain a variety of effective information through the surveillance camera, but it is difficult to share, let alone security. Effective management of information.
In fact, the security monitoring system not only puts forward higher requirements on the security monitoring technology itself, but also puts forward higher requirements on the storage of monitoring data. With the increase in the scale and requirements of security monitoring systems, the higher requirements for monitoring data can be reflected in several main aspects:
(1) Reliability and integrity of monitoring data storage;
(2) The scalability of monitoring data storage, including: how to meet the needs of data collection with higher resolution or more collection points, and how to meet the needs of longer data collection time;
(3) How the monitoring data of each part is shared with each other.
Can storage technologies (such as DAS, NAS, IPSAN, FCSAN, etc.) that are widely used in IT application solutions be directly applied to security monitoring systems? Can storage technologies in IT technology be integrated with monitoring systems? Theoretically It is entirely possible, that is, the existing storage technology can fully meet these needs. Considering the characteristics of video surveillance data stream (stream) access, if the stream access features of security monitoring are reasonably customized, the price / performance ratio will be more reasonable. Therefore, the storage technology can fully meet the needs of the new generation of security monitoring systems for the future review of security data, and can solve the problem of reliable, complete and shared storage of monitoring data.
