i have following Samsung hardware at my site 2 NVR Model SNR 3200 with 8TB HDD in each NVR. 18 x Model SNB-3000 12 x Model SNC-570 and 2 PTZ Cams Model 3301 H i access my cams by writing IP address of my NVRs in IE. The NVRs provide me play back and record of my videos. Due to Repeat Recording Mode setting, the data starts deleting itself after the HDD get full. this way i lost my data. I want to backup this data before it start deleting. I tried Net-i-Viewer but it cannot backup the cameras simultaneously. It is not feasible to backup all my 32 cams one by one . i am looking for any solution that can backup my data over CDs automatically before it starts deleting from my NVR HDDs. Can any Body help me?
