I recently had an unfortunate episode requiring the exporting of a clip off a Dahua NVR, but I needed someone else to do it… (and no, I was not in jail, trying to instruct someone else to pull exonerating evidence off some CCTV, if that was what you were thinking)…
My original method of using the in-built web UI off the NVR, manual streaming conversion via VLC Player (after fiddling with it for a temporal configuration change to “enable” playback of .dav files) was just not going to “cut it”…
So, once I had the time, I waded into the battle of the forever-changing, forever-beta nature of Dahua firmware, software and hodge-podge end-user solutions…
SmartPSS
There happened to be a “new” version of the SmartPSS software (v2.002.0000008.0.T.190801); which was supposedly released a month ago (2019/08/01, as of writing this). This software was “supposed” to have had some (old) “enforced 1 hour video export” bug fixed. However, I was pulling my hair out as to why I could not seem to limit the video clip I chose to export. I finally found my clue and therefore am posting this here for posterity (actually, to enable other people to follow the same instructions to do this).
