    Dahua NVR password recovery or reset

    Some NVR5216 models have a reset button on the motherboard, some don't - you gotta open it to check. If yours has one, hold it for 30 seconds while powering on to factory reset, otherwise you'll need pattern unlock or contact your dealer for a reset code.

    Dahua NVR - NVR5216-EI - Any easy way for external service to flag/mark the recording timeline?

    Nah, Dahua's HTTP API doesn't have a webhook or API call to mark/bookmark timeline recordings like Synology does. Your best bet is using the NVR's physical alarm inputs - wire your ESP board outputs to trigger those, which will mark the timeline as alarm events (shows up red in playback).
