  • Promote prosperity of HD industries Monitoring Storage usher in new opportunities

        So far, security monitoring technology has undergone three stages of development: analog, digital, networked. Correspondingly, video surveillance storage has gone through several stages: VCR analog data storage, DVR digital data storage, centralized network storage, and the last two years appears the cloud storage technology. Due to be moving, to meet the growing demand for high-definition monitor image storage, the storage industry continues to break through technical difficulties, so that image storage technology has been greatly enhanced.
        Monitoring Storage Development Status
        The diversity of market demand for a variety of storage solutions provide market space. Therefore, in the future for a long period of time, DVR, NVR, SDI-DVR and FCSAN, IPSAN other storage solutions will co-exist. Cloud computing and cloud storage are likely in the next few years, the market for video surveillance pattern a tremendous impact, and video surveillance industry into a new, higher stage of development.
        HD image storage drive HD surveillance industry, frankly, to do high-definition storage market research is a difficult thing. Because, now is not the year of the storage market products of a single DVR era, corresponding to the front of the camera, shipments, we can calculate the DVR statistics and annual shipments; then follow the sales price when the DVR, you can statistics and calculate the total sales of the DVR market. With video technology in recent years the rapid development of intelligent security monitoring has entered the era of high definition and big data, we can say video surveillance technology and the market has undergone a qualitative change. With security products and technology continues to improve, businesses for video surveillance image quality requirements are high, along with the data storage requirements are also increasing, which is bound to promote the video surveillance storage market changes. Speaking from the application level, in fact, all of the monitoring image information, useful, and often only 1% or even less than 1%, 99% of the information is useless information. But precisely because of this 99% percent of the useless information groundwork before settling 1% of useful information.
        Therefore, whether it is useful or useless video information, should be stored, which is bound to bring huge storage pressure. video surveillance images are often a lot of industry events and subsequent verification of cases important evidence in the social security monitoring, banking, judicial and other system applications, video surveillance image storage time is often in 1-3 months or even longer. Monitoring to improve image clarity, image storage will inevitably bring greater pressure. For HD IP camera capture high-definition images, you need network storage system (including storage servers and storage devices).
        Standards-based H.264 compression technology HD IP camera, all the way to full real-time image 720P HD stream is 2Mbps, recording one hour of storage space required is about 900M or so; way 1080P HD Camcorder, stream is 8Mbps, 24 小时 video produced amount of data 84GB, 30 天 amount of recorded data 2520GB, 1 amount of data in video 30TB. Even so, the same way if the construction of 100 cameras, one year of storage space required approximately 3PB. If it is a safe city with a total monitoring of large ones are usually a few thousand to tens of thousands of road, it is hard to imagine such storage, traditional storage media and systems simply can not meet demand. Due to be moving, to meet the growing demand for high-definition monitor image storage, the storage industry continues to break through technical difficulties, so that image storage technology has been greatly enhanced.
        Currently, IT industry data used in hard disk capacity has reached mainstream TB level, 2TB, 3TB hard drive data have also been put on the market. 1G calculate the amount of data per hour, 1TB hard drive data can be stored around the 720P video 1000 hours or 1000 Lu 720P HD IP camera1 hours of image data. Data hard drive capacity upgrade, good to meet the high-definition video surveillance image storage requirements, making it a powerful high-definition monitor market developments driving force.
        HD video surveillance storage technology development path and the status of video surveillance storage market, the main form of storage, including DVR, NVR, SDI-DVR, IPSAN, FCSAN other, and if in accordance with the transfer agreement to points, can be divided into a file transfer protocol, block transfer protocol, streaming media protocol three. As customer needs improvement and technology development trend, the security industry for storage applications also derived from a variety of modes.
        HD storage drive monitoring industrial development
        Frankly, do high-definition storage market research is a relatively difficult task. Because, now is not the year of the storage market products of a single DVR era, corresponding to the front-end surveillance camera´s annual shipments, we can calculate the DVR statistics and annual shipments; then follow the sales price when the DVR, you can statistics and calculate the total sales of the DVR market.
        Speaking from the application level, in fact, all of the monitoring image information, useful, and often only 1% or even less than 1%, 99% of the information is useless information.
