Position:Should define video server above all (DVS) with videocorder of present digital hard disk (DVR) distinction, simple method is, DVR is OK stand-alone system runs an operation, also have network interface, the administrative software that DVS must need network undertakes operating through the network, use and manage.
The development of any product, the development of the related its product that general metropolis accompanies and technology, and video server is not exceptional also. As the development that how prevents the relevant technology such as technology of technology, the computer, network, promoting the development process of video server jointly.
At present DVR held the mainstream market that how prevents. These a few years as network monitoring arisen, especially as " restful city " construction strength is increased gradually, video server product and its application begin to warm up, people is higher and higher also to the attention degree of video server, all sorts of DVS products appear like the ground like emerge come out, adumbrative DVS application begins to enter to rise period. Especially after business experience enters telegraphic operation how to prevent the market, the characteristic of DVS gets be reflectinged adequately in platform of telegraphic operation business, manufacturer of equipment of server of a lot of video, for telecommunication " global eye " platform and net connect " wide world " platform is received reached control agreement to make custom-built development. Equipment manufacturer and win-win of platform firm cooperation, pursue in all development.
Returning those who have specification of a bit need is: IP network camera (IPcamera) . IPcamera with height compositive image is collected, analysis of encode of image processing, video, intelligence, network is transmitted and a lot of and advanced technology such as memory, can more stick into civilian the demand that prevents market user, will be a when video server develops next important way.
From the point of current condition, 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.
The main application market of DVS is the supervisory system of telegraphic class. Of Chinese telecommunication " global eye " the new standard of video monitoring standard of platform (3 version) in be being made now, new standard lieutenant general used SIP agreement to serve as platform advocate dominate a deliberation, the fixed position of facilitating video, attestation, control, exchange, transmit, the business processing such as plan cost, management. So the development of video server product, must accord with the demand that these rising markets expand, can miss good opportunity otherwise. Want to be able to accord with the demand that network monitoring expands and direction, must want to if PNP of memory of many code shedding, this locality, heartbeat, DDNS, Web, U, video is added,can come true prevent attestation of bogus, telegraphic class, speech closely to telling, frame is led suit oneself, wireless / 3G application, call the police processing means (Mail, short message, accord with the standard of the industry and standard. On the function of the product, want to be able to assure the quality of image, the small delay time that the network transmits and bandwidth wave motion make the same score stability, the product is stabilized reliably, have very strong custom-built capacity.
