I have a Luma 310 camera system. 3 of the 8 cameras suddenly stopped recording events. All 8 cameras are operational and viewed remotely and from my home pc the 3 havent recorded any activety that its set to record. I have rebooted the NVR and tried to change the region the 3 cameras view to see if doing so would help. It did not. when i make a change i receive the message you see above followed by the name of the camera. I do not want to reset the NVR and go through setting up IP addresses all over again. Has this occurred w anyone else can what can be done to correct the issue?
