NVR development and front-end ip camera, back-end monitoring platform has a great relationship, for the front-end equipment, requires the ability to access more manufacturers of compatible IP Camera; For monitoring platform, but also requires NVR has good access performance, NVR During architecture design requires consideration of these factors. The development of back-end devices are now differentiated into two directions: one direction is stored centrally, the main equipment for the IPSAN, NAS, etc.; another is a distributed storage direction, the main equipment for the NVR. Centralized storage is mainly the existence of network bandwidth requirements, the exchange capacity of the switch high requirements for central storage server performance requirements, so that the overall cost will be very high. Another issue is the centralized storage of data insecurity, because it is centrally stored, if the storage server is out of the question, the entire data may be lost; relative to the centralized storage, distributed storage data are stored in a single NVR, only centers need to see a preview and playback data, it needs to be connected NVR, network bandwidth requirements is relatively low, the cost of the entire project will be low. NVR is currently divided into PC-based and embedded NVR NVR, PC-style PC-based NVR mainly, on the inside of a NVR management software runs; embedded NVR is mainly embedded hardware and software platform for NVR. Two kinds of comparison, PC-based NVR hardware development difficulty, and software features to be slightly more powerful, easier to access different IP Camera manufacturers, you can just follow the SDK access; rather difficult to develop embedded NVR hardware relatively large, but long run, the overall cost of the hardware and software embedded NVR low, the system is stable. Chip manufacturers have realized NVR provides opportunities for development, chip manufacturers are already developed for NVR using the chip. Chip manufacturers to provide more complete development kit SDK, generally provide a complete solution for the development of embedded NVR difficulty is gradually reduced.
