So I hope this might be an ineresting workaround for the guys who want to use IVS and don't wanna have gaps in the important moment the IVS event occurs like me and
@aristobrat .
Because it seems the gap is forced by the way the Dahua NVR records the IVS events. Instead of making a second file for the IVS event, it stops the regular record, starts an IVS record and when the event is over it starts a regular record again. While doing this the gap of 2-3 seconds seems to appear.
So my idea was preventing the NVR to make a new file and keep regular recording. Of course i wanna know when IVS events did occur and so i decided to do snapshots when IVS is triggered.
In the NVR WebUI it is not that much fun to find the pictures in the playback, because they are listed neither in the timeline nor in the file list. You have to go to "File List" -> "More" and the select "Pic" for the Type in the "Download by File" tab.
Within SmartPSS its easier with the Playback. You can switch between "Record" and "Picture" in the left pane and expand the "File List" with the little arrow on the right. So you can quickly watch evidence for interesting pictures and then switch back to record and watch the corresponding record from the timeline.
I'm hoping Dahua will fix the issue with the IVS recording in any way. For me it would be the best solution if a second file is recorded simultaneously. But I would also be happy if it works without gaps in any way.
This is how my IVS Events look now, without gaps. Mounted this cam for testing purposes only...
