    [FIXED]Help Needed: Cameras keep disconnecting and reconnecting after Dahua NVR firmware update to V4 from V3.

    Looks like I need a new NVR that has the capabilities to run 4 4K cameras and 2 12MP fisheye at max FPS and resolution.

    Are you saying the NVR5216-8P-4KS2E (October 2019 build) can only handle one(1) 12MP, fisheye camera(…plus the other 4 4K)?

    The NVR was fine before the FW update. As you said, it was a work horse.

    That's the thing, both fisheye cameras are working just fine. No issues with them. I can plug them out and see if that stabilises the others.

    I do not know how to do a factory reset. The NVR was powered off, then turned off using the physical switch in the back of the NVR.

    Will try this. Question: If I did want to run all 6 cameras at maximum FPS and Bit Rate it sounds as if I would need a different NVR with that capability?

    Had not tried isolating individual cameras to ferret out the one causing the problem. I will give that a go. I had plugged out all the cameras; turned off the nvr for a minute; turned it back on and plugged in all the cameras. I noticed that the cameras' visual feeds on the monitor were no...

    Andy gave me the link for the specific nvr I wanted to update. Decided to update nvr’s firmware to fix a present and persistent issue with one of my cameras shutting off when there was consistent motion being recorded. Otherwise I would have left the firmware alone.

    Microphone for DH-IPC-EBW81230 not working? Try this.

    Since I bought my Dahua 12MP Panoramic Fisheye Camera (IPC-EBW81230), in 2019, the microphone has not worked. Or so I thought. Watch the following video: . This may sort out your problem. My cameras are connected to a Dahua NVR and not to a PC running BlueIris.
