Replacement for QC888 NVR that works with Qsee cameras?

My QC888 NVR (about 3 years old) bit the dust- the hard drive and fan don't spin up, and there is a faint ticking sound from the power supply area of the PCB- I'm going to call it dead. Q-See is now out of business as discussed earlier.

The cameras that it used are QCN8099B. From what I read, the Q-See stuff is Dahua-based. I'm looking for recommendations for a replacement NVR that would work with the existing cameras- Any suggestions of models with similar feature sets as the QC888? I'm only using 4 cameras today, but might want to add one or two more.

Thank you,

FYI - adding info - looks like a Dahua OEM kit

FYI - could just be the power supply.... often the AC/DC adapter goes south on electronics also..

While I don't have a way to test it under load or check ripple, the 48V 2A AC/DC Adapter is measuring 49.5v DC on a voltmeter with no load, so that suggested to me that the failure is more likely the board. The power supply section of the PCB has one LED that comes on too.

btw - can run Blue Iris or SmartPSS on a PC as a NVR substitute ... would need a small PoE switch of course ( or the likefor PoE power )
 
After some searching:
I see the NVR2108HS-8P-4KS2 and NVR2108-8P-4KS2 etc- Around $170-180. These seem to have an 80Mbps limit on incoming data (which I doubt would be an issue for me with 4 cameras but might be with 8+)
I see the NVR4208-8P-4KS2 and friends - Around $220-290- These have a 200Mbps limit on data.
I see the mentioned EmpireTech NVR5208-8P-4KS2E at $320 with a 320Mbps limit on data.

Is there some kind of feature comparison between these models, or are they pretty much the same aside for the bandwidth limit? I see some other places mention that the NVR5208 has things like License Plate recognition and fisheye dewarp, but it doesn't seem consistent so I wonder if the installed software varies?

(Also, are they all as loud as the QC888? That little 12v fan was a loud one and I like the quiet with it dead...)

Thank you,

FYI - pizza box NVR tend to have higher rpm fans which make noise... some have opted to replace the fan with a pricier one. Others go with a SFF business class PC and run VMS software and a separate PoE switch ( which can also have noisy fans if you get a larger industrial data center version of them )
 
The Q-see bankrupt this year,but dahua nvr can work with them under onvif protocle, not plug and play, so need some further setting can make it work.

FYI - some of the older models are Dahua OEM so will work fine with Dahua API / protocals. You will probably need to adjust / sync IP, port, user / passowrd, and stream info.
( iirc Q-see used to use port 85 for their webserver for example )
Some newer, recent Q-see models were from another OEM ( i.e. not Dahua ).
