Hi fellow members, I am newbie to this forum but have always followed it for any advise in the past.
I was recently in China for a work trip and I happened to find a CCTV wholesale market in Guangzhou.
I have a Dahua NVR2108HS-8P-4KS2 which I have been using with Ali express cameras currently which has english language and it has been working fine for over 1.5 years.
During this trip I bought some chinese cameras IPC-HDW4631C-A and the seller told me that it would work with english NVR. He also activated all cameras in front of my using some chinese portal and demonstrated using a English version 16ch NVR. All was working fine.
When I returned from the trip and connected the cameras to my NVR I have been having an error "Device is not compatible". I thought I was taking small risk by buying the chinese cameras as they didn't have english version in stock.
I have done lot of google search but have been unable to find a solution to make this work with the NVR.
Can anyone here shed some light on if this can work with my NVR ?

Thank you for your help!

Your NVR is most likely a International version and that is a good thing, most likely he demonstrated the cameras on a Chinese "hacked" firmware version NVR. Dahua as of late and also users on this form have reported this issue of Incompatibility between Chinese region Cameras and International NVR's. Its a shame you came here after the fact because these Issues are well documented here in the cliffnotes about chinese cams. Not sure you are going to be able to solve this issue without taking a hit on your wallet.
Perhaps @EMPIRETECANDY could have some say on this but he has stated before that Dahua has put locks in the NVR's firmware so hacked cams cannot be supported. I know that some of the older models chinese cams can be used with the older NVR's but have not seen a fix here for this yet. Good luck and perhaps Andy can give you the info because he is a Dahua dealer here.

Good info on this model here---->IPC-HDW4631C-A - any thoughts?

I'm using some chinese market cameras with a dahua nvr. It works only because I have old nvr firmware. If I update the firmware I'll lose access to the cameras. As mentioned earlier, this issue has been know on the forum, for about a year or so I'm guessing. It's just a market segmentation issue being enforced by the firmware in the nvr.

How old is your firmware ? Can you post your firmware built date and version ? May be we can learn something from that.

Looks like you were about 4 months too late. My info is that the chinese market camera rejection began with V3.215.0000001.0.R, 2018-03-26 . I'm running 3.210.0003.0, 2017-04-18, and am stuck there until my 8 chinese market cameras break or I replace them for some other reason. I do almost all viewing with SmartPSS and the nvr firmware is doing what I need it to. I haven't tried BI myself, but I've sure read a lot of posts that make it sound like it "beats the pants" off of the nvrs.

Do you think I can downgrade the firmware to 3.210 ? I also want basic viewing and recording access. I use Smart PSS as well for viewing or use the mobile app.

You can try General_NVR2XXX-4KS2_Eng_V3.215.0000000.0.R.171114.bin

it's new & it's bad for you now.
What about ONVIF or RTSP connecting method from NVR to IPC?

How would ONVIF be any different ? Wouldn't it recognise the device as same way and block the access ?
I guess RTSP would need me to buy a POE switch ? I am not very familiar with RTSP yet but any guidance would be appreciated.

So I tried to connect the camera with ONVIF and it shows the same error message. Device is not compatible
