Please read the original post. Trust me, I don't want to update the firmware on the NVR, but I fear I have no alternative. Same issue as you had.If you really want to update the firmware just do what I posted. But like what the others said if you dont have to its probably better not to if youre not having problems. I've only updated my Hik NVR because the firmware it had on it was too old to process the newer 180degree dual sensor cameras
