I successfully tinkered and was able to save Dahua camera snapshots & videos triggered by IVS to my NAS shared folder instead of using the internal SD card. I was just playing around trying to fine tune my IVS intrusion/tripwires. Completely useless other than backup purposes. It would be handy if the Data Src on the Dahua GUI playback screen was able to select the NAS shared folder instead of only SD card. I assume, this is not possible? If it was possible, would have lesser need of having SD cards in all my cameras.
