I was looking into the logs of my DS-7608NI-I2/8P as I'd been experiencing what seemed to be sporadic restarts. It's something much stranger. A user "SuperUser" is logged in with no remote host IP listed, then the camera's all restart. Two or three times a day. Currently there are no open ports set in the router and the NVR is plugged into it. A search of the forum only found one passing thread mentioning this. Nothing found in a Google search either. WTF?
