Which NVR to upgrade with from Hikvision

Hi all,

I have an old LaView system with 16 PoE cameras. The NVR started to act up, so I decided to upgrade. There are three options on the table:

* DS-7616NXI-I2 - I already got this NVR and the AI helps to mark footage for humans and cars, which I find helpful. I am talking about Motion Detection 2.0. I bought this on Amazon and will probably have no support at all.

*DS-7716NXI-I4 - I ordered this from an an online store claiming to be Hikvision authorized reseller. I thought this would be my final choice, it has some better specs vs. the 7616, including more HDD slots. The order kept lingering for weeks and now they say this model is discontinued. They are proposing to give me the next one below.

* DS-7716NI-M4 - This would be same price as the 7716nxi, i.e. $500. It would probably have better bandwidth than the I series, but these M series do not have any AI from what I understand. With no AI, I am left with the need to upgrade cameras to have smarter functionality.

What should I do? Is there any benefit of getting the M series besides the higher bandwidth for higher resolution cameras in the future? I may upgrade few cameras, but don't really want to upgrade all of them.

Or should I just keep the 7616nxi from Amazon that is without support?

Btw, this is for a residence, I don't look at the cameras often, all I need is to maybe set an alarm in the future when I leave home, run a smart search here and there, and find easily relevant footage for playback.

Thanks.
 
Many come HERE after having a useless phone call with support LOL and end up getting better help here.

If the device is a big enough savings over the one with "support" go for it.

Motion Detection 2.0 isn't all it is cracked up to be, but if it is working for you, then go for it. Many find it still produces a lot of false triggers.

Now do keep in mind that having the NVR do the AI instead of the cameras, it does throttle the NVR in some capacity.

Most prefer the AI and if you have the NVR do it because your cameras cannot, then it is limited to only 4 cameras even thought it is a 16 channel NVR

I have enabled Motion Detection 2.0 on 15 cameras and it seems to work without complaining. This is another mystery of specs to me, between all of AI engines and options, it is hard to figure out which AI feature is limited to 4 channels and why MD works on all of them

This said, I agree that MD2.0 is not 100 accurate. It picks up occasionally cats and leaves as people. But I don't use any alarm at all currently, so can't talk about the experience is having an NVR that notifies you if someone is entering the garage in the middle of the night :)

the main rule on both Dahua and HIK cams / NVR...

if camera have some AI function (Smart Motion Detection, IVS with human & cars filtering etc) then You don't need NVR with AI functions.. All AI is done on camera and NVR only stores video footage & events & marks on HDDs...

AI enabled NVR's are only for situation when You have dumb cameras - then You can add some AI to them. And only in this situations AI limits on NVR (like IVS only for 4 channels) is counted when you enable this AI function done on NVR for dumb camera channel.

And another important rule for AI:

Smart Motion Detection, both in Dahua & HIK execution are simplest and most dumb AI filtering with can generate some false positives (and negatives).
Much better is properly configured IVS with human/cars filtering..

ps. be aware that HIK have revisions of it's products - especially NVR's.. they are labeled using letters like (A), (B), (C), (D) after model number.. each have different feature set (different AI functions & limits) and each have different firmware line... usually only latest one have fresh firmware...

Price? Does it work correctly with human/vehicle detection sent by the cameras?

$299 (4HDD) or $499 (8 HDD).

Network Video Recorder - Ubiquiti Store

A video recorder with (4) 2.5/3.5" HDD bays that can support up to 30 days of storage for (18) 4K cameras or (60) Full HD cameras.

No, it does support the built-in AI functions on individual cameras right now. As matter of fact, it does not even support simple motion detection.

When using with non-Ubiquiti brand cameras, if you want anything more than constant recording, you need to add Unifi AI Ports ($199/ea) for that. With the AI-Ports, it's incredible. The accuracy is lights out. Including with ALPR function at distances where the camera lens has no business capturing plates.

Right now, it's 1 per cam. It will be as many as 5 per AI port with future firmware upgrades.

Regardless of cost, it's worth it. Either through the web or on a phone, the software interface is incredible. Feels like something designed by Apple, not China. So easy find the info you need.

I love the image quality of Chinese camera (Dahua, Hik), but the rest of the experience always seemed like a joke. I now have that image quality with a modern, professional-looking product. Set up with Internet Explorer 2 years after support ended? No thanks.

I'm looking for a NVR upgrade too.

One of the parameters I'm looking for is increasing the incoming bandwidth- so the NVR can handle higher MP cameras better. The I2 has a incoming bandwidth of 160Mbps whereas the M4 has 256Mbps. (So that's 10Mbps vs 16Mbps per camera.) I'm not sure if that is something that concerns you at all? My current NVR is 10Mbps/ channel and that seems to be a bottle neck with 4k cameras (affecting the image quality.)

One should always try for the highest bandwidth they can afford. As you said, as MP increases, it really takes a hit to the bandwidth. And use any AI functions in the NVR and some have their bandwidth or other capacity cut by doing so.

He's probably saving a wayward NVR user from ripping his hair out on the other side of the Globe.
