HIKVision NVR with IPCam - Computing correct IPCam to match NVR

Hi

I have checked that HIKVision NVR has different incoming bandwidth and based on how I understand it, we need to know the incoming bandwidth in order to properly select a camera that will not consume bandwidth that is greater than the NVR's capacity.
Please correct me if my understanding is incorrect. Let us take DS-7104NI as an example (4-port NVR). Its incoming bandwidth is 25Mbps and it has 4-ports
25 / 4 = 6.25

So this means each port's maximum IPCam resolution is only up to 6.25 Mb...
