NVR decoding capability and live view

Hallo everybody.
I'm setting up a new system for video surveillance.
I've just bought 12 HikVision DS-2CD2343G0-I 2.8mm cameras (4MP, H265+, check link)

Now I need a NVR to handle those cameras.

I'm looking those two models:
DS-7616NI-K2
DS-7616NI-I2

Due to the fact that K serie is stuck on V3 firmware, I'm moving on I serie that has regular updates and V4 firmware.

I don't need NVR with POE ports because of the LAN architecture of my home. Cameras will be connected to two POE switches in two different floors and the NVR is on another floor.

Incoming bandwidth of DS-7616NI-I2 is 160Mbps.
According to what I read, I think that each camera set on 4MP/30fps H265+ should stream at approximately 6 or 8 Mbps.
Worst case: 8 * 12 = 96 Mbps.
Hope this is correct, so at the moment I'm ok and I can add other cameras in the future.

Now here you are my main concern: I need to broadcast the live view on all my TVs, so I bought a DVB modulator that works flawlessly.
Then, I discovered (reading this forum) that I must pay attention to decoding capability of my DVR.
DS-7616NI-I2 can decode 8-ch @ 4MP (30fps), so I cannot live view all the 12 4MP cameras at once!
I've studied a lot of specifications of different NVR but this appear to me as a limit even in the most expensive HikVision NVR.

I can record all the streams but I can not live view all the streams at the same time. Am I wrong?

So I'm asking you: can I record all the 12 4MP streams and live view all the 12 cameras with a different resolution, using another main stream or a sub stream lower than 4MP? Is this a possible scenario? Or is there another possible solution to live view all the 12 cameras at the same time? (something like an "Auto change stream type" option that is valid only for live view)

Then my secondary concern: I've bought 305 meters of cat6 UTP 23 AWG LAN cable but is CCA, not solid copper. Which type of problem may I encounter? Should I trash this cable and buy a solid copper cable? (I have not connected the camera yet).
Edit: I've read a lot about this. So I'm trashing old cable and buying a new solid copper one.

Hope I made it all clear.

Thank you in advance for any suggestions.

Edit: I changed the title, the old one was too generic.

You’ll have no issue there. The NVR automatically switches to view the cameras sub stream while in a split screen format in live view, then back to main stream when you go back to a single selection.

CAT5E would’ve been fine CAT6 is overkill.

If it uses the sub stream does that not increase the incoming band width as there are two incoming streams from the same camera into the NVR ?

Yes it will, the total incoming bandwidth will be the sum of the main steam and sub stream of each connected camera. However the total of the sub streams won’t amount to much and the total will be well below the 160Mbps incoming bandwidth of the NVR.

V4 is actually available on the K series, but the I series is a little better anyways

It WAS available on the K series. Hikvision withdrew it from the UK portal on January 21st. I posted on this forum and another suppliers forum in the UK regarding this. They went to them for more information. Hikvision denied that it had ever been available in the Portal, even though many had downloaded it. They now say that although it works on the K series, it's buggy and they don't support it.

That’s interesting... I was given V4.0 for my K series directly From Hikvision USA in California
 
Just for your information:
I've set up everything and there's no problem in live view.
I can record in full res all the cameras and live view everything without any problem.
I have at least other 80/90 Mbps free in incoming bandwidth.
And there is also a "channel zero" option (I have not used it) to minimize band occupation for live view.
So if you have any concern, go on, everything's gonna be alright ;)

Yes you can set the channel zero bit rate and frames per second to suit. It will encode whatever you have showing on the monitor output into a single stream. IE if you have 16 cameras but the main monitor is displaying a 3 x 3 split of cameras 1-9 - the channel zero stream will be the 3 x 3 grid of cameras 1-9

Having GUI 4.0 for the unit is not what it seems. Yes it is the latest and greatest but they have a major bug on it that is still being fixed. The older interface... the 3.4.X is still one of the better/stable interfaces. Major thing about GUI 4.0 is the issue with the file system. Unit seems to be recording but when you go back to look at your playback it seems footage disappears. Only thing I have seen that is a plus with the GUI 4.0 is that the later revisions have limited support for Firefox and Chrome so you will not be limited to IE. Then there is the option to unbind Hik-connect accounts easily.

Your idea regarding decoding is wrong. The unit will be recording all channels at the highest resolution you have set the camera to but decoding is about viewing the live view or playback in main stream. If you max out the decoding (viewing too many main stream video at once) then you will get a “No resources” error for certain cameras. That being said, in the multi stream view you will be fine because those are showing cameras at a lower resolution. When you double click to show the camera full screen is when it will switch to main stream. Either that or you manually set the cameras in the multi screen view to all realtime (main stream). By default it will be on balanced so it will automatically switch by itself.

So to answer your question.... Yes you can record all 12 of your 4mp cameras at the same time. You will just have issues displaying in the multi screen view in all main stream.
 
came across this thread, my nvr w/4.0 won't allow me to review playback, or even live view from within the nvr GUI. can i download an earlier firmware and flash the nvr to the 3.4.x? i'm so sick of this nvr and cameras not connecting, etc.
 
Once you are on NVR GUI 4.0 it will not let you downgrade. What firmware were you on before and what is the current firmware? Earlier versions of 4.0 had issues/bugs. Make sure you are on the latest version and update the firmware in sequential order. For the reviewing playback you were talking about.... I would check the firmware version. Make sure it is upgraded to the latest version. Then go into Storage/Storage Device and select your hard drive and click repair. That should fix the issue.

If you upgraded from 3.4.X to 4.0.... The file systems are different between the two. It is usually recommended to initialize (format) your hard drive. If not possible then do the repair option. Just a note that it will take some time to repair. Hours depending on hard drive size. Don't worry. It is still recording and you can still use your NVR while it is repairing. 4.0 firmware and up. Early 4.0 firmware had a bug where the unit cannot find footage. The fix is to upgrade firmware and then to the hard drive repair on all drives.
 
It will let you downgrade from V4 to V3 but it will default the unit and return it to inactive status. I did this with one of mine without issue

new nvr-5208-8p-4ks2e running 4.000.0000001.5 date: 12-6-2019

it came with the nvr purchased over a month ago.

when i look at dahua wiki i found a newer firmware, but i think it's for the US version or the non "e" version. I dont want to brick my NVR, here's the link i'm talking about.

DahuaWiki

dahuawiki.com dahuawiki.com
 
Are we talking about the same thing? I thought we were talking about Hikvision/Hikvision OEM products and the difference between firmware 3.4.X and 4.0. So now we are talking about a Dahua NVR? I am a little confused.
 
sorry, it was a long night last night, i'm having mega issues with my new dahua nvr with 4.0, disregard.

Are you sure it was Hikvision in California? Hikvision North America has three tech support offices. In USA is in Dallas, City of Industry and Canada is in Montreal.
 
I’m not sure I understand what your trying to clarify. City of industry is in California... I’m in California, my supplier is in California, and occasionally when I’m at my suppliers office we will call his contact at Hikvision (in California) with questions or firmware requests.

Lots of time when you call in to tech support to get help then it will go to once of those offices for help.
