Which NVR to use with 4 x 8mp Hikvision cameras - DS-2CD2387G2H-LIU?

Hi

I have searched but am unable to find an up to date answer, so here goes.

I am looking to install 4 x 8mp Hikvision cameras - DS-2CD2387G2H-LIU.
I have read through several posts discussing a similar topic but nothing specific.
Which NVR would you recommend?

I understand bandwidth is the main concern but some of the other posts mention that it is also possible that certain models may not support all the functionality of the cameras.

I am thinking it may have to be the DS-7608NI-M2/8P, but it is a little expensive.


Thanks in advance.

Yes that's the one you want. The additional expense will outweigh the frustration of using a lesser model that struggles to cope.

Thanks for the prompt response.

What do you think about dropping down to 4mp cameras to keep the cost down? Would it be a noticeable drop in picture quality?

The 4MP and 8MP share the same 1/1.8" sensor (the older non hybrid ColorVu used a 1/1.2" sensor on the 8MP). I use both the 4 and the 8. The 4MP should be slightly better for nighttime performance but I've not noticed. If you're covering a wide area then the 8MP will have a clear advantage. Whichever you go for I'd recommend the standard 4mm lens unless you're sure you need the stupidly wide angle of the 2.8mm.

Ultimately you can use any NVR that will support the cameras and you'll only run into real issues if you are running high frame rates with their associated higher bit rates. However the decoding performance of lesser models means that it can get a bit laggy on some models when displaying multiscreen locally and also there's greater restriction on how many simultaneous images you can play back. The DS-7608NXI-I2/8P/S will be slightly less in both cost and performance. At a push you could even use the DS-7608NXI-K2/8P if you're only using 4 cameras. However with the 'M' with it's 'ultra' tag you can happily run the cameras at full frame rate and maximum bit rate without seeing any issues.

Edit: Regarding Picture Quality. Both 4 and 8 will look very similar when displayed on most screens. If your display is 1080P than both are being shrunk to fit the screen as their native resolution is higher. The benefit of the 8MP is that you can use a little digital zoom when playing back (as you're not actually zooming in but just displaying the image at its native size)

Superb, thanks again.

Is Hikvision preparing to upgrade the M-series anytime soon? I am in the same boat, trying to replace my EOL I-Series NVR.
Using DS-2CD2387G2-L(U) camera's (ColorVu).

Hi @Ray Arts

We are not aware of any new NVR models being released that will offer significantly better/different performance to the M-series models.

Just remember that if you're getting an M series and want the new AcuSearch function you would have to splash out on the iDS-7716NXI-M4 which is a beast of a machine. The AcuSearch function is reliant on an NXI model. In other markets a DS-7616NXI-M2/VPro is available but not in the UK.

Thanks, I would like to pick one with at least 4 port PoE connectivity. This DS-7616NXI-M2/VPro does not have it, correct?

 

[Dan]

Correct, the DS-7616NXI-M2/VPro is a non-PoE model

Last question, I currently use DS-2CD2387G2-L(U)
These are all ColorVu, not AcuSearch I believe. Does it make sense to buy an NVR with AcuSearch? Is AcuSearch the same as AcuSense?
I just want to make sure I have the right combination with all of the features unlocked.

Hi @Ray Arts

AcuSearch is a new feature built into certain NVRs to improve playback searching via smart filtering features, AcuSearch will work with all current EasyIP 4.0 cameras including AcuSense, ColorVu, Live-Guard, and Hybrid Light models.

Yea, that's good advice, wish I knew that when I started

6mm would be good in many cases but the availability is poor; they're usually a special order. Back in the good old days of analogue cameras (when we pre built - camera, lens, housing, IR); a 3.5-8mm varifocal lens might be standard on a 1/3" sensor camera. At the wide end it would be (from memory) about 78 degrees (it was more standardised then as lenses and image sensors were generally 1/3" or 1/2" with C or CS mount so viewing angles would be the same between camera and lens combinations unless you put a 1/2" lens on a 1/3" camera). I think now the 4mm fixed lens at 93/95 degrees is a little wide.

Great, would the DS-7608NI-M2/8P as successor to my DS-7808NI-I2 be able to have all of the AccuSense and AccuSearch options? Or would you advise the much more expensive vPro? All of my camera's are DS-2CD2387G2-LU (I believe these have AccuSense?)

The DS-7608NI-M2/8P has no onboard AcuSense processing. If you have all AcuSense cameras that's not an issue, as the cameras do the processing and pass the metadata back to the NVR (no need for AcuSense on the NVR). The flip side of that is that you still need an AcuSense on the NVR if you want/need that specific AcuSearch function. It's probably a bit of a niche feature for residential systems. While playing back, it allows you to drag a box around a target person and then the NVR's AcuSearch will try to find all clips that feature that target. As mentioned previously, the vPro may simply be unavailable to you depending on what country you're in. It's not available in the UK and so to get an M series model that has the function you'd have to leap up to the 16 camera, 4 HDD iDS-7716NXI-M4(16P)

Thanks for the clarification, the vPro model is available in the Netherlands but double the price of the non vPro model.
I'll go for the non vPro as I probably don't need the AcuSearch function anyway, at least not given the steep price.
