In fact transition from analog to network monitoring equipment is not impossible to achieve, after all, for the network equipment, and its future applications and convenience applications in future technologies mature, are analog surveillance difficult unbeatable. However, because of the huge engineering overhead as well as a long-term process of adaptation to face, therefore, is for the analog switch to the network such work needs, is bound to make more careful preparation in order to guarantee that the practical realization of the demand on the same time so that we inputs minimized. Video surveillance of the pace of development in the past two years seems to have been difficult to quickly describe for users, demand seems to have become one of the most important reference direction. In most of our applications, high-definition is often an important factor in the demand for network monitoring, HD high-resolution surveillance cameras are in many of the key sites, Strip essential equipment. However, because not all sites are requested definition video, for the needs of the transition to the network camera by the analog monitoring, we can use the digital encoder picture converted from analog signals to digital signals to be transmitted and stored in the front of the surveillance camera. When the phasing out of analog equipment, we can make use of network technology defense equipment to achieve control of analog devices. Or we can network with analog equipment coexistence VNS software and analog control terminal combination, of course, will have a significantly different in the two control characteristics. Although in both in Formwork mixed practice, have a relatively good working condition, but they cost a significant difference. By transcoding mode network integration equipment, although such work may seem to make this transition process smoother, but will pay more money in the cost of inputs. For the latter, its system, as a still in application mode try to build have to be more simple than the former. In addition to the terminal, the transmission cable is one of the important facilities that we have to pay attention to, in the use of analog camera and network camera on the transmission medium or a clear difference in transmission applications, engineering applications in this transition to avoid Since the medium resulting from differences in signal distress is undoubtedly a test project with important factors. Therefore, in similar system builders, we tend to use optical fiber as a mixed communication mode network transmission medium, so not only can avoid the transfer of the equipment in a variety of media by different line quality fiber with its higher transmission transfer effect of the environment to a more compatible. In addition, network, network pressure under the coverage of the entire management system will suddenly increased network environment can assume security monitoring applications, or application of compression standards whether the communication stream control within the acceptable range, all we need to consider. A long time, whenever we talk about high-definition monitor brings us convenience, will naturally take into account high-definition monitor for the storage of huge pressure, this problem will naturally seem especially prominent in the transition from analog to network monitor system. But for this storage problem, we may wish to use the front-end storage mode, both to some extent alleviate the back-end equipment to deal with stress, and at the same time be able to improve the safety factor of the information, so that you can ensure the security of the information in the device is powered off or contact with the back-end accidents. In addition to the information before and after storage, fast feedback can be achieved for the device in the event of a fault, or the identification of equipment storage and compatibility, as well as the time of storage capacity greater storage pressure, are also monitoring system after adding a new component the aspect can not be ignored.
