NVR products are mainly divided into two categories : one is based on the so-called SOC hardware-based embedded system products, general OS is Linux. Anotherip ip camera surveillance camera is an industrial grade computer system products , OS will give WINCE, LINUX choice. The latter advantage is based on replacing the CPU speed, short development cycle, corresponding to the development of technical requirements is not high, supports a variety of video compression. The disadvantage is that the stability of reliability than the SOC NVR to almost, because such NVR is used to extract the soft way , and therefore can not support the full real-time applications are more large ones . However , the former is the SOC 's NVR products have their advantages and disadvantages: advantages is its stability, high reliability , the device application consumption ( power consumption ) has obvious advantages, more suitable for application in a variety of different applications , and low cost of the product . SOC 's current road NVR mostly 32,64 or more large ones , can achieve 25FPS full-time . The disadvantage is that hardware changes difficult ( easy to replace the platform and CPU), a long development cycle. But on the security systems ip camera system product development trend, mainly NVR will be for the development of SOC . For now, we can be chosen according to different needs . For example, in accessip camera system NVR Recorder management applications ones are few, you can consider using the former type of NVR. If you want to be able to access the larger ones , you can opt for the latter . Support the front-end hardware diversity Users generally considered NVR should only compatible network cameras, or support only one brand of network cameras. In fact, not at all , and some brands of NVR in addition to the current support their brand , but also the support of other more well-known brands, so that surveillance camera security systems regardless of the agent , or engineering providers and users, in the selection of NVR and IP Camera with a range of applications on a broader , and thus can be selected according to the different needs and environments. This video surveillance in the current conversion of analog to digital transition , if the mixed analog and digital front-end use , NVR really help this busy. Some brands of products on the basis of supporting IP Camera also supports analog video access, in its local codec , so the number of mixed -mode approach is bound to be one of the most popular network camera NVR Recorder and most rapid manner acceptable . By the way network camera security camera system while also slowly into the all-digital network monitoring . Under the characteristics of such products can offer different options for everyone . |
