  • HD video surveillance several major problems solutions

        In the current video surveillance market , high-definition video surveillance has become a mainstream trend, although high-definition video surveillance is already hot, but several major problems facing HD video surveillance need to be addressed .
        Transmission and storage, systems integrators can be solved by the high cost of inputs ; display and management of HD manufacturers need to spend some effort to improve the underlying hardware and software ; effect in terms of improving night vision , but also a relatively small investment , but also the most likely to be able to make to improve user satisfaction solution .
        Compared with standard-definition video surveillance, the advantages of high-definition network monitoring is very obvious, but by marketing more than two years , will inevitably encounter the following types of questions:
        1, the transmission aspect
        HD IP camera will generally choose 720P or 1080P solution , if you want to achieve the desired image effect , we need 2 ~ 8M network bandwidth , and if one of them should have a few hundred points system , that data flow across the network will be quite large , and the video stream in real time data streams , will continue to result in continued pressure on network-related switching equipment , which requires plenty of homework to do in network planning.
        Solution:
        As the costs continue to reduce the cable , plus a high-performance fiber-optic local area network switch completely to form the high-speed network can be used , Gigabit to the desktop is a very easy thing . With the popularity of broadband networks , especially this year, has just launched the "triple play" , the rate of households have reached the tens of megabytes to hundreds of megabytes , Copper light eventually brought us cheap high-speed Internet. For remote transmission of high-definition video images do not need to have a long time.
        2 , storage
        On an issue referred to the huge problem of data stream , or if the data is aggregated into center of each storage node , the bandwidth of the center of the inlet pressure and the storage capacity is a big challenge.
        Solution:
        Currently only done in the IPSAN and storage media heavily invested , IPSAN best embedded architecture , much less plug boards, high stability, but the drawback is poor compatibility moment, the secondary development of less flexible . Most NVR products on the market are based on X86 architecture , which is the server plus an array of cards, installed applications, servers and disk arrays combo, compatibility is better. If IPSAN way , you need to use a storage medium enterprise-class hard drive , so as to play a IPSAN advantage in speed of data storage and security. For some small systems do not require too long if you save time , while data security requirements are not too high, the market can use the server to complete the mainstream storage functions.
        3 , showing respect
        Many of the HD manufacturers just focus on the front of the camera pixels , without a corresponding development of high-definition video decoder, only around a PC screen to watch high-definition images , high-definition images can not be independent of the big screen on the display .
        Solution:
        For high-definition screen TV wall, we have developed a high-definition decoder , the front transmission over HD graphics effectively restore the connection to the big screen, high-definition input interface, high-definition picture perfect to show on the screen above .
        4 , management
        Many manufacturers still do the traditional definition analog camera thinking HD cameras, bought ready-made hardware solutions , using standard algorithms provided by third parties MPEG4 , and only provides a network interface , conduct some simple digitization , as the platform behind how the camera hardware and data flow management , as he did those underlying core algorithm and technology, simply can not be achieved.
        Solution:
        Possible choice of hardware with a rich interface front-end equipment , such as alarms , SD card , intercom, audio, 485 , etc., you can do the project in accordance with the Party ´s program requirements, flexible portfolio , no longer a separate additional customization features. Software to have a variety of access methods, such as WEB, client , a large platform that provides SDK development kit that can be flexibly and third-party software for docking . To function modules as complete as possible , such as alarms, streaming media, storage services, etc. , can be used directly in the project.
        5 night respect
        In the case of day -lit , high-definition is very easy, once used in low light or nighttime surveillance when needed , HD became powerless it. Since most HD cameras using CMOS sensors have lower sensitivity to light , if not with infrared light , in the night is dark, and we want to monitor most of the time period is precisely guard at night , so high expectations of high-definition video systems will become a decoration. Solution:
        We have accumulated a wealth of experience in night vision surveillance , provide different solutions depending on the site conditions. Such as infrared light program , IRCUT technology , illumination chips.
        Comments:
        In our frenzy behind on HD products , should be more calm to analyze the five above-mentioned practical issues involved , each one how to solve the problem , it is rarely considered by many manufacturers , their focus is often confined to a particular the product itself , as long as pixels high , is a high-definition , high-end system solution.
