Transmission and storage problem is the system integrator can solve the high cost of investment in high-definition display and management of monitoring equipment manufacturers need to spend some effort to improve the underlying hardware and software ; aspect in improving night vision , investment is relatively small, it is most likely to improve customer 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: HD ip cameras usually choose 720P or 1080P solution , if you want to achieve the desired image effects , it is necessary network bandwidth 2 ~ 8M , if a system has hundreds of monitoring points , the whole network will be very large data streams , and video streams in real time data stream , it will give the relevant network switching equipment caused by constant pressure , which requires plenty of homework to do in network planning. As the cable costs continue to decrease , 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 home networks have reached tens of megabytes or even hundreds of megabytes , and ultimately brought us cheap high-speed Internet. Remote transmission of high-definition video images has been just around the corner . 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. 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 , secondary development 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. 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 . For high-definition screen TV wall, has now developed a HD decoder , the front-end ip cameras transmit images over the definition of effective reduction connected to a large screen HD input interface, high-definition picture perfect to show on the screen above . Many high-definition equipment manufacturers or in accordance with the idea of traditional analog cameras do HD ip camera , 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 back of the platform how the camera hardware and data flow management , as he did those underlying core algorithm and technology, simply can not be achieved. 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. In the case of day -lit , high-definition is very easy to do , and once the application environment of low light or at night when the need to monitor , HD would be difficult to play a role. Since most HD ip 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. Today, we have accumulated a wealth of experience in night vision surveillance can provide different solutions depending on the site conditions. Such as infrared light program , IRCUT technology , illumination chips.
