chuck it out, get proper english firmware cameras you will be happier.No matter how do I connect the camera. It won't work with neither DH private or ONVIF protocols. Just RTSP. The NVR stopped recognizing it after I upgraded the NVR firmware to the newest one. This is the known issue with the Chinese modded cameras. I thought you would bring some new ideas.
Are your all cameras use English modded FW version? If yes, then it explains why it works. In my case I'm using chinese firmware. NVR has stopped seeing the cameras. I can't upgrade the cameras back to English, can't downgrade the NVR. The camera jut became a toy at home.
