Everybody talks network video server and its matrix product - [1]

With in front has mentioned intelligence video is relevant, the feature with the main another that DVS develops, will be intelligence is changed. Intelligence changes monitoring to be able to reduce the working load of monitoring personnel considerably, reduce of all kinds call the police the fail to report sth of incident and sign up for probability by accident, accordingly, the DVS of framework of processor of RISC ＋ DSP, criterion more those who have a product to change is advantageous go qualitative. In this domain, will take the kind that cooperates external, introduce advanced image processing and intelligence to identify a technology substantially, drive the rate that how defends technical intelligence to change development.

The application of video server, photograph comparing DVR, a marked characteristic is its system is based on a network to undertake a framework, compress the collection of video system, transmit, memory, retrieve, exchange, show, the functional module such as management has network. DVS also can choose to whether configure hard disk in this locality at present, regard video data as a kind of solution of memory. But its are general the configuration that the capacity wants to compare DVR wants little, also somebody regards DVS a branch that is DVR accordingly, or of DVR simplify edition, but the place that the tendentiousness that its apply still has a lot of to differ, analyse simply, DVR more considers to assure the dependability that this locality stores, and the transmission efficiency that DVS more considers a network and quality, and the communication with outside system is normative, mode of these two kinds of application can have conflict sometimes; Additional, DVR is OK stand-alone moves and become an organic whole oneself, and DVS cannot cut apart to come true alone with its system commonly, it is the front equipment of network supervisory system, since be one part of the system, of agreement of its communication, control and systematic platform accept an agreement, want to consider the level of platform manufacturer, must undertake systematic market moves effectively into ability, this and DVR also have very big different; Be worth what carry is, DVR also can assume the role of DVS sometimes, DVR still is DVS, its function should change along with what apply program demand and change, will tell commonly, in plan design Shi Yingfu grants to compare clear fixed position.

So, I think, DVS still cannot replace DVR completely at present, both between still supplement each other, the advantage is complementary.
