HIKVision NVR with IPCam - Computing correct IPCam to match NVR

[bien gomez]

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
Is there a calculator or a computation that HIK installers use that we can follow or perhaps a guide that we can use in order to properly know how many and what is the maximum IPCam resolution we can bundle with the HIK NVR?

Thanks.

Hi bien,

It's not done on a port-by-port quota, but an overall limit. For example, you can have a camera connected to one port that needs 12Mbps and another that only needs 2Mbps, and both would work fine.

We have a bandwidth and storage calculator embedded into our blog

Hikvision themselves have also produced their own bandwidth and storage calculator

Hi Kieran.

I just wanted to make sure. If incoming bandwidth is @ 25 Mbps for a 4-port NVR, this means as long as the total of my IPCam will not exceed the 24 Mbps, this is ok.

Please confirm, Thanks.

That's correct, yes. I wouldn't design a system in which you cut it so close to the maximum though - listed maximum incoming bandwidth might not always be what it can provide in practise.

Hi Kieran.

I will keep that in mind. Thanks.
