NVR for 8x4Mpixel cameras

[Cyberslider]

Hi all!
I searching a good Dahua NVR with 8POE ports &H.265 important...
There is:
NVR4108HS-8P-4KS2 or NVR4108-8P-4KS2
NVR4208-8P-4KS2
NVR5208-8P-4KS2

I want use max. 8*4Mpixel Dahua cameras (so, not 4K, but better than 1080P) maybe.. 15fps is enough, with high bandwith as possible...
I don't understand, how many bandwith is enough? 80mbit, or need more?
Wich model can record 8 channel simultaneously with 4Mpixel resolution cca. max 10mbit/channel?

Thanks for information!
edit: oh maybe the decoding is not equal as recording/encoding?

If possible, I would go with the NVR5208 because it support 320Mbps and give me room to grow in the future

You don't need 320Mbps for 8 cameras.

Save yourself some cash and get the NVR4108-8P for one HDD or NVR4208-8P for two HDDs

You need 80mbps max for 8 cameras. If you own a busy shop with 8 cameras running this will still be ok, so 80Mbps is plenty as you'll run the cameras at 8Mbps variable MAX.

You'll be able to run 4MP x 8 x 25fps no problem.

Well yes, my dahua cams max. bitrate is 10mbit/s.. 8x10=80Mbit. I think 15fps ok, but of course 25 fps is better, but the storage capacity!
Sometimes need to check the system from other location, and use the substream too. The full bandwith contain the substream too(?), so I just thinking, maybe better the 4208 that's right?

Yes, get the NVR4208-8P if you want more space. I paid £200 in the UK for mine, so it should be about that locally. 15fps is ok but 25fps isn't much more and 8mbit/s max vbr is fine for that I find.

If on a budget and this is for residential, then I'd get NVR4108-8P + 6TB HDD. 6TB is plenty. Rather have this than NVR4208-8P and 4TB HDD which will cost more.

Be aware the total bandwidth is main + sub, so 8192 + 1024 x 8 not just 8192 x 8.

Actually I've changed my mind - didn't realise they did this one: 16 channels and 8 poe ports. You can add some more cameras later then and the price difference isn't that big.

NVR4216-8P

Thanks for informations!
16 cameras? In my next life, in a bigger house LOL

I checked two cameras:
IPC-HDW4431C-A-V2 & IPC-HDBW4431R-S-v2 both 4M/20 fps maximum.
Do you recommend any other?

Check out the Dahua Starlight thread but I would use those in darker areas only. Everyone has a different view!

My 4431 or 4421 (can't remember) do 25fps
