Dahua NVR: continuous record + motion detection marking?

Out of the box, my new NVR5216-16P-4KS2E was configured for continuous recording, which is what I want. But, I was hoping for a way to have the timeline indicate motion events.

What exactly is the best way to go about this? Using all Dahua cameras.
 
Okay, but since that's a "storage" schedule it implies, to me, that it's going to potentially record events twice, once continuous and again for all motion?

And how about the individual channel settings - do I then need to enable Video Detect and NOT select "Record Channel"? Or leave that enabled?

The nvr does not record anything twice. When the are no events, it starts a new file (marked in green on the timeline) once per hour. When an event happens, it closes the "green" file, and starts a new one (yellow for motion, orange for IVS, and red for hardwired trigger input). When the recording time for the event is over, that file is closed and a new green file is started. I don't particularly like that method, but it is what it is. For events to record there are a few places they have to be set up in both the camera and nvr. The events need to be enabled, have a record channel set, and the storage schedule set. There were a few times it took me a while to find all the settings that had to be made.

Ah, I see. They should really change that to just record an index file of “events” for the bigger files. (Yeah I know, get BI, but this is enough for me).

I used to run other, older Dahua cams using the native in-cam software to record motion to a NAS and it was very buggy - it would occasionally have 2 or 3 different files going recording the same frames (but for different durations).
 
Until the next-to-last nvr firmware update, there was a major problem with lost frames when an event happened and the file switch occurred. You lost the exact frames you needed the most. Had that not been fixed I would have either pulled out all my hair or switched to BI by now. At this point the nvr is working well for how I use it.
