Hello, I'm trying to build a NVR (network video recorder) on an ARM based embedded linux board. I have seen NVR manufacturers mentioning specs in the form of a relation like: <no. of channels> * <resolution> @ <fps> I understand that this relation is quite straightforward in terms of network bandwidth. However, I need to know how one can determine the hardware specifications (CPU, RAM, etc.) for a given relation. For example, say I need to support 8 channels * 1080p @ 30fps, how can I determine the required hardware specifications for my board? And similarly, for the same hardware, I would like to know what max. fps can be supported for 8 * 2K cameras. Thanks in advance.
